Longevity Manifesto

We live in a time when longevity is no longer a dream, but a tangible reality. Never before have human beings had so much knowledge, tools and opportunities to live longer. However, this extraordinary achievement is accompanied by a fundamental question:

Do we really live better or simply longer?

In recent decades, advances in medicine, technology and socioeconomic conditions have contributed significantly to the increase inlife expectancy (lifespan) in most developed countries. Today, living beyond 80 years is a common reality in many areas of the world, with the global average rising steadily (WHO, 2021). However, this achievement is accompanied by a growing gap between lifespan and the quality with which it is lived.

The international scientific literature distinguishes increasingly clearly between lifespan-the total number of years lived-and healthspan, or years lived in good health, without significant disability or disabling chronic disease (AGE.MPG.DE; PMC.NCBI.NLM.NIH.GOV). By definition, healthspan is equal to or less than lifespan, and the gap between the two-already wide-is steadily growing. According to a study in JAMA Network Open, in 2019 this gap averaged 9.6 years globally, marking a 13 percent increase since 2000 (Garmany et al., 2024).

This phenomenon can be observed across the board: in the United States, for example, there is a life expectancy of about 78-79 years, compared with only 66-67 years in good health (ScienceDaily.com, 2020). Similarly, in the European Union, 2020 Eurostat data show that individuals live on average 78-82 percent of their lives in optimal health, meaning that more than 15 out of 80 years are often marked by chronic disease or disability (EC.EUROPA.EU, 2022).

This longevity paradox-living longer but in compromised health-has significant individual, health, and economic implications. In clinical settings, an increasing number of older people experience a prolonged phase of functional decline, which profoundly impacts their quality of life. In systemic terms, the cost of age-related chronic diseases is estimated at more than $47 trillion globally over the past two decades, including both direct health care costs and lost productivity (Nature.com, 2021).

Far from being a mere question of age, longevity is shaping up to be a question of quality.

The goal is not simply to add years to life, but life to years.

– WHO Decade of Healthy Aging 2021-2030 initiative.

This requires a paradigm shift: no longer just measuring survival, but promoting autonomy, functionality, physical and cognitive well-being throughout the lifespan.

Our Integrated Approach to Longevity

Our goal as Longevia is to propose a personalized plan based on the genetic, epigenetic and clinical profile of the individual, through an integrated and personalized medicine approach that combines: Biohacking, Predictive Medicine, Advanced and Targeted Therapies to Innovative Instrumentation

At the heart of this approach is the Longevia Protocol, (divided into the 3 phases Check-up 360, Action and Prevention).

This model will enable us to extend healthspan-the healthy years of life-by delaying biological aging and measurably improving quality of life.“

Longevia Protocol

Longevity, according to Longevia therefore, must truly be an advancement; it cannot simply add years to life: it must bring life into those years.
We can identify the signs of biological aging early, intervene in a targeted, personalized and measurable way, and build pathways that promote lasting health at any age.

This Manifesto represents a commitment to a new model of health: not reactive but preventive, not generic but tailored, not passive but participatory. A model that recognizes that the true value of longevity lies not in its duration but in its quality.

Because living longer is not enough.
It is time to live better, longer.

Scientific Foundations of Longevity in Health:
Evidence, Key Concepts and Integrated Approach

Numerous data show a growing gap between total life span(lifespan) and years lived in good health(healthspan). Globally, life expectancy at birth has increased from about 66.8 years in 2000 to 73.1 years in 2019, while healthy life expectancy (HALE) has only increased from ~58.1 to 63.5 years ( Life expectancy and Healthy life expectancy ). In other words, the increase in HALE (about +5.3 years) has not kept pace with that of average life expectancy (+6.4 years) ( Life expectancy and Healthy life expectancy ).

This has led to an expanding healthspan-lifespan gap: a study of 183 WHO member countries indicates that the average gap has grown from ~8.5 years in 2000 to ~9.6 years in 2019 (+13%) ( Global Healthspan-Lifespan Gaps Among 183 World Health Organization Member States – PMC ). On a global average, individuals live up to ~63 years in health compared to an average life span of ~72.5 years ( Global Healthspan-Lifespan Gaps Among 183 World Health Organization Member States – PMC ). In European Union countries, similarly, healthy years account for ~78-82% of total life span ( How many healthy life years for EU men and women? – Products Eurostat News – Eurostat ) – this implies that about 15-18 years (out of ~80) are lived with chronic diseases or disabilities.

Gap between lifespan and healthspan (life years vs. healthy years)

( Global Healthspan-Lifespan Gaps Among 183 World Health Organization Member States – PMC ) Trends in the healthspan-lifespan gap globally (2000-2019). The “healthspan-lifespan” gap increased from ~8.5 years to ~9.6 years ( Global Healthspan-Lifespan Gaps Among 183 World Health Organization Member States – PMCs. ).

This “longevity paradox” (living longer but with more years of poor health) is a cross-documented phenomenon and underscores the need for interventions to compress morbidity, adding health to the added years ( Global Healthspan-Lifespan Gaps Among 183 World Health Organization Member States – PMC )(Longevity leap: mind the healthspan gap | npj Regenerative Medicine).

Adding life to years, not just years to life

The idea that medicine should aim not only to extend life, but to improve its quality, has distant roots. As early as 1946, the Gerontological Society of America adopted the motto “To add life to years, not just years to life” in the first issue of the Journal of Gerontology ( Longevity’s Purposes – PMC ). This principle states that efforts on longevity should aim “not merely to increase time itself, but to extend the period of healthy and productive life” ( Longevity’s Purposes – PMC ). The same concept is now being promoted by international bodies: for example, WHO and the UN emphasize that “we have added years to life; now it is time to add life to years.” In the launch of the Decade of Healthy Aging 2021-2030, it is clearly stated that it is not enough to prolong survival, but to ensure well-being and autonomy in advanced ages ( What is the UN Decade of Healthy Aging? – The Platform ) ( What is the UN Decade of Healthy Aging? – The Platform ). In summary, the goal of modern medicine is redefined as adding life to years-that is, health, function, and meaning to the years gained-and not just years to life. This paradigm shift emphasizes the quality of longevity as much as the quantity of years.

Prevention, predictive medicine and early identification of biological aging

The key to healthy longevity lies in a proactive approach: preventing functional decline early by identifying biological signs of aging before they translate into disease. It is reiterated in geriatric and public health circles that prevention of age-related diseases is critical in the ageing population era(Biological age in healthy elderly predicts aging-related diseases including dementia | Scientific Reports). This requires predictive medicine tools capable of identifying the individual’s “rate of aging.” Indeed, scientific studies show that the rate of aging varies from person to person:biological age can deviate from chronological age, reflecting the body’s actual state of wear and tear(Biological age in healthy elderly predicts aging-related diseases including dementia | Scientific Reports). Measuring biological aging through biomarkers (e.g., epigenetic clocks, indicators of inflammation, etc.) allows identification of individuals at risk of accelerated aging. Detecting such signals early allows intervention before established pathologies arise. For example, a prospective study concluded that“accelerated” biological age relative to age peers is a strong predictor of increased risk of chronic morbidity and dementia in the still-healthy elderly(Biological age in healthy elderly predicts aging-related diseases including dementia | Scientific Reports). In general, as experts in artificial intelligence applied to gerontology note, “accurately predicting biological age is essential for early diagnosis of age-related diseases”(Application of AI in biological age prediction – ScienceDirect.com). Accordingly, advanced geriatric screening programs are being developed: for example, periodic assessments of biomarkers of aging (metabolic, inflammatory, epigenetic profile) at middle age, so that targeted preventive measures (lifestyle, early therapies) can be implemented before clinical signs of decline appear(Biological age in healthy elderly predicts aging-related diseases including dementia | Scientific Reports) ( Targeting Cellular Senescence in Aging and Age-Related Diseases: Challenges, Considerations, and the Emerging Role of Senolytic and Senomorphic Therapies – PMC ). This preventive and predictive approach represents a crucial shift from “reactive” medicine-which intervenes only when damage is done-to medicine geared toward “adding life to the years” by intervening in the aging process itself.

Integrated scientific approach to longevity (biohacking, gene therapies, senolytics, cell therapies, anti-aging technologies)

Longevity science takes an interdisciplinary approach, combining lifestyle interventions with the most advanced biomedical anti-aging therapies. In addition to behavioral and nutritional measures (so-called biohacking in a broad sense, which includes e.g., intermittent fasting, exercise, sleep optimization, targeted supplements, etc.), research is developing high-tech interventions to slow aging at the molecular level.

Ongoing geroscientific studies include “a variety of approaches, including drug therapies, gene therapies, and cell therapies” ( Targeting Cellular Senescence in Aging and Age-Related Diseases: Challenges, Considerations, and the Emerging Role of Senolytic and Senomorphic Therapies – PMC ). In practice, they range from geroprotective drugs (small molecules) to genome interventions and stem cells… Promising strategies include the use of senolytics, drugs that can eliminate senescent cells from the body. Selective elimination of these “aged” cells in animal models has been shown to extend healthy lifespan and delay the onset of many age-related diseases ( Targeting senescent cells for a healthier longevity: the roadmap for an era of global aging – PMC ).

As reported in a review in Nature, senolytics have shown preclinical efficacy in preventing or attenuating frailty, cancer, and various cardiovascular, metabolic, neurological, etc., opening “a new avenue for the treatment of age-related disorders” ( Targeting senescent cells for a healthier longevity: the roadmap for an era of global aging – PMC ). On the gene therapy front, a notable example is telomerase activation: a study in adult mice showed that a single pro-telomerase gene therapy can extend the median lifespan of mice by 24% (when treated at age 1 year) without increasing tumor incidence(Telomerase gene therapy increases longevity – Nature). Cell and regenerative therapies are also in development-for example, stem cell transplantation or partial cell reprogramming protocols-with the goal of repairing age-damaged tissues and restoring youthful function. A perspective published in npj Regenerative Medicine summarizes that it takes “multidimensional action enhanced by modern anti-senescence and regenerative technologies” to close the healthspangap (Longevity leap: mind the healthspan gap | npj Regenerative Medicine). In summary, the integrated approach to longevity combines preventive lifestyle interventions and innovative therapeutic interventions (pharmacological, genetic, and cellular) targeting the biological mechanisms of aging, configuring geroscience as a discipline aimed at treating aging itself in order to prevent age-related diseases(Longevity leap: mind the healthspan gap | npj Regenerative Medicine) ( Targeting Cellular Senescence in Aging and Age-Related Diseases: Challenges, Considerations, and the Emerging Role of Senolytic and Senomorphic Therapies – PMC ).

Genetic, epigenetic, and clinical data for personalized health and prevention protocols

Finally, longevity medicine is moving toward personalized health models built on individual genetic and epigenetic profiles. Because aging is a heterogeneous process that is different for each individual, the integrated collection and analysis of genomic, epigenetic, and clinical data makes it possible to design tailored preventive protocols. The scholars point out that the aging process varies among individuals in both rate and mode, and that “by monitoring the characteristics of an individual’s senescent cells, guidance can be provided for personalized treatments, formulating preventive and therapeutic strategies based on each individual’s aging characteristics” ( Targeting Cellular Senescence in Aging and Age-Related Diseases: Challenges, Considerations, and the Emerging Role of Senolytic and Senomorphic Therapies – PMC ). In practice, through advanced examinations (genetic panels, epigenetic clocks from DNA, metabolic and inflammatory markers) it is possible to identify early who is aging faster than expected and intervene accordingly. Biological age diagnostics provide early warning signals: for example, assays of specific microRNAs and epigenetic changes in blood have been shown to correlate more closely with biological age than with registry age, suggesting the potential of this information in guiding targeted preventive interventions(Biological age in healthy elderly predicts aging-related diseases including dementia | Scientific Reports). The goal is to move away from a “one-size-fits-all” approach in which everyone follows a longevity protocol based on their own profile. Pilot studies demonstrate the feasibility of such a model: in an investigation of the genetics of skin aging, the combined analysis of genetic polymorphisms and blood chemistry test results yielded “a more complete and accurate picture of a patient’s overall health status” ( Genetical Signature-An Example of a Personalized Skin Aging Investigation with Possible Implementation in Clinical Practice – PMC ). The authors conclude that these results “confirm the approach of personalized medicine applied to aging” and advocate the development of algorithms capable of integrating large volumes of individual data to provide assessments and clinical recommendations on a personalized basis ( Genetical Signature-An Example of a Personalized Skin Aging Investigation with Possible Implementation in Clinical Practice – PMC ). Looking forward, with the help of big data and artificial intelligence, it will be possible to devise an aging prevention protocol for each person based on his or her genomic (e.g., genetic predispositions), epigenetic (e.g., biological age from DNA methylation) and clinical/physiological (e.g., indicators of frailty) data, fully realizing the vision of precision medicine applied to longevity.

Living better and longer: Can it be done?

Nutrition: The Fuel of Long Life

We are what we eat: science confirms thatnutrition is an essential pillar for living long and healthy lives. A balanced diet not only provides energy, but modulates inflammation, metabolic processes and even gut flora, directly influencing longevity. The world’s long-lived populations share similar eating habits: predominance of plant foods, legumes, nuts, and whole grains, with meat consumed rarely and in small portions. The Mediterranean Diet-rich in vegetables, legumes, whole grains, fish, olive oil and low in sugar and industrial foods-is also associated with longer life spans and fewer chronic diseases ( The Effects of the Mediterranean Diet on Health and Gut Microbiota – PMC )

Indeed, much recent research links healthy eating to concrete benefits: reduced risk of diabetes and cardiovascular disease, lower incidence of some cancers, and better cognitive function in old age ( The Effects of the Mediterranean Diet on Health and Gut Microbiota – PMC ).

A key aspect that has recently emerged is the role of the gut microbiome. A diet rich in fiber (from vegetables, fruits, legumes and whole grains) promotes a greater diversity of “good” gut bacteria, which produce anti-inflammatory and protective substances.In contrast, an excess of sugars, processed meats and ultra-processed foods can negatively alter the microbiota. European studies have shown that, in the elderly, improving the diet toward a Mediterranean pattern for one year leads to positive changes in the microbiome associated with healthier aging and less frailty ( The Effects of the Mediterranean Diet on Health and Gut Microbiota – PMC ).

In the Blue Zones, the diet has a clear “plant slant“: legumes such as beans and lentils are the cornerstone of the centenarians’ diet, while meat is consumed only a few times a month, in small quantities ( Blue Zones: Lessons From the World’s Longest Lived – PMC ). Another common habit is the“80% rule” of Okinawa: stopping at about 80% satiety(hara hachi bu) to avoid excess calories. This simple rule reduces metabolic stress and helps maintain a healthy weight, and is shared in various forms by many long-lived communities ( Blue Zones: Lessons From the World’s Longest Lived – PMC ).

Finally, hydration and moderation are crucial components. Drinking enough water and consuming alcoholic beverages in extreme moderation (in the Blue Zones, red wine rich in polyphenols such as Sardinian Cannonau, but always 1-2 glasses per day and never accumulated) are associated with benefits. The use of herbs and spices instead of salt, and the habit of having light meals in the evening, also fit into pro-longevity eating patterns.

In practice: To nurture longevity through diet, we can adopt some practical guidelines right away:

Favor fresh, whole foods: Fill your plate with vegetables, fruits, legumes, whole grains and nuts. These foods provide fiber, vitamins and antioxidants that fight inflammation and cellular aging.
Limit excess and ultra-processed foods: Reduce added sugars, sugary drinks, packaged snacks high in salt and trans fats. Prefer a fruit, a handful of nuts or natural yogurt as a snack.

Choose healthy fats: Use extra virgin olive oil as your main condiment. Consume fish (rich in omega-3s useful for the heart and brain) and avocados regularly, while avoiding fried foods and excess animal fats.
Apply the “80% rule”: Eat slowly and listen to your body’s signals. Stop before you feel completely full-you will still get all the nutrients you need while avoiding unnecessary calories ( Blue Zones: Lessons From the World’s Longest Lived – PMC ).
No extreme diets, yes to overnight fasting: No need to follow punitive regimens. It is more helpful to maintain a balanced diet each day. Give your body adequate digestive rest at night (e.g., light dinner at least 2-3 hours before bedtime, avoiding eating until breakfast).

Nutrition: The Fuel of Long Life

Movement is one of the most powerful protective factors for a long and healthy life. Human beings are made to move: inactivity, on the contrary, contributes to the development of cardiovascular disease, diabetes, osteoporosis and cognitive decline. Research indicates that regular moderate physical activity is enough to reap huge benefits: the risk of death from any cause is significantly lower in active people than in sedentary people ( Physical activity ). The World Health Organization estimates that those who do not achieve at least minimum levels of physical activity(150 minutes per week of moderate activity) have a 20-30% increased risk of death compared to those who are sufficiently active ( Physical activity ).

In long-lived populations, however, we will not find marathon runners or gym fanatics: the secret lies in moving naturally and often. In Blue Zones, for example, the elderly walk every day, do housework or gardening, climb stairs – daily activities that keep their hearts, muscles and joints exercising without the need for strenuous workouts ( Blue Zones: Lessons From the World’s Longest Lived – PMC ). This constant “non-exercise movement” accumulates benefits over time: better circulation, more efficient metabolism, weight under control. Of course, structured sport is fine too if you like it, but it is not the only way. What is important is to break the sedentary lifestyle: too much time sitting (at a desk or on the couch) is itself a risk factor, so it is important to get up, stretch and take a walk at regular intervals.

Regular physical activity has documented anti-aging effects. With aerobic exercise (such as brisk walking, biking, swimming) the heart becomes more efficient, blood pressure is lowered, and cholesterol and blood sugar levels improve. With strength exercise (such as light weight lifting or free-body exercises), muscle and bone mass are preserved, counteracting the sarcopenia and osteoporosis typical of old age. It is also important to work on balance and flexibility (yoga, tai chi, balance exercises) especially for the elderly to prevent falls and maintain independence in daily movements. It is never too late to start: studies show that even people over 70 can improve strength and functional capacity with appropriate exercises.

Bottom line: Integrating more movement into daily life is within everyone’s reach with a few practical steps:

Move your body at every opportunity: Walk or use a bike for short trips instead of a car whenever possible. Take the stairs instead of the elevator. During work, get up every hour for a few minutes of movement.
Rediscover the pleasure of physical activity: Choose activities you enjoy – dancing, hiking in nature, playing tennis with a friend, swimming – so it will be easier to be consistent. The key is regularity: better 30 minutes a day of something you enjoy than 2 hours at the gym once a month.
Follow the guidelines (in your own way): Aim for at least 150 min per week of moderate activity (e.g., 30 min x 5 days of brisk walking) or 75 min of vigorous activity. You can break it up into shorter sessions (even 3 sessions of 10 min a day count!). Add, 2-3 times a week, some muscle-strengthening exercises (even at home with water bottles as weights).
Break up sedentariness: If your job is sedentary, set a reminder every hour to get up and take a walk or do some stretching. Doing chores with energy or working in the garden are also good forms of natural movement.
Don’t get discouraged and listen to your body: If you are starting from scratch, gradually increase activity to avoid injury. Even a few minutes at first is better than nothing. Choose convenient times and settings (e.g., an early morning walk in a pleasant place). Every extra step literally counts toward your longevity.

Stress Management and Mental Well-Being

The mind and body are intertwined in our health. Chronic stress, depression, anxiety, and isolation can accelerate biological aging as much as physical factors such as poor diet or being sedentary. When we are under constant stress, our bodies remain on continuous “alert”: hormones such as cortisol rise, systemic inflammation rises, and “ inflammaging” is generated.

Studies show that chronic stress accelerates cellular aging processes, for example by shortening telomeres (the protective “caps” of chromosomes) more rapidly ( The Link between Chronic Stress and Accelerated Aging – PMC ). In addition, prolonged stress can promote the onset or worsening of cardiovascular disease, immune disorders and cognitive decline. In contrast, a peaceful and resilient mind contributes to a more favorable hormonal and inflammatory profile, protecting our organs in the long run.Long-lived populations teach us much about how to manage stress. In the Blue Zones, while not immune to stress, people have developed daily rituals to “release” tension. Some people pray, some take an afternoon nap, and some devote time to family or hobbies every day. This constant downshifting prevents stress from building up to the point where it becomes harmful.

Another crucial aspect is keeping the brain active and curious: spending time on creative hobbies, learning new things (a language, a musical instrument, strategy games) creates new neural connections and helps the brain stay flexible. Several studies link a mentally stimulating life to a lower risk of cognitive decline and dementia.

Finally, asking for help when needed is crucial. Mental well-being does not mean never experiencing stress or sadness, but knowing how to recognize and manage them. Talking about your worries with people you trust or a professional, practicing mindfulness or relaxation techniques, and-if necessary-taking advantage of psychological support are all elements of a winning mental longevity strategy.

In practice: Here are some practical techniques for cultivating emotional resilience and keeping stress under control:

Carve out moments of calm each day: Even 10-15 minutes of deep breathing, meditation, prayer or yoga can lower stress levels if practiced regularly. Find what works for you-it can also be a quiet walk in the fresh air or listening to soothing music before bed.
Practice gratitude and positive thinking: At the end of each day, think of (or jot down) 3 things you are grateful for. Cultivating an attitude of gratitude helps reduce anxiety and improve mood. Similarly, try to reframe difficult situations in a positive light(reframing): instead of “today was a horrible day,” think “today I faced tough challenges, but I overcame them, and tomorrow will be better.”
Immerse yourself in a hobby you are passionate about: Whether it is painting, playing an instrument, gardening, cooking or reading, devoting time to an activity that totally immerses you in the “flow” reduces stress and provides satisfaction. Set small, achievable goals in your hobby (e.g., finish a chapter in a book, learn a new recipe) to feel a sense of accomplishment and progression.
Cultivate relationships (more on this later): Spending quality time with friends and family is a powerful antidote to daily stress. A chat with a loved one can ease worries and make us feel supported. Don’t isolate yourself: if you feel tension rising, seek the company of those who make you feel good.

Learn to say no and delegate: An often self-induced stress comes from overloading yourself with commitments. Recognize your limits: you don’t have to be perfect or available all the time. Prioritizing things and letting go of the superfluous is liberating. Organize your time, make lists of what is really important and give yourself guilt-free breaks.

Sleep and Circadian Rhythms

Good sleep is an often-overlooked pillar of longevity. During deep sleep, the body activates powerful repair mechanisms: damaged cells are regenerated, the brain eliminates toxins accumulated during wakefulness, memory and learning are consolidated, and key hormones (such as appetite and stress hormones) are rebalanced.

Conversely, chronic sleep deprivation is associated with increased inflammation, metabolic imbalances (predisposing to obesity and diabetes) and increased risk of neurodegenerative diseases such as Alzheimer’s.Epidemiological studies clearly show a relationship between sleep duration/quality and life expectancy. Sleeping too little (or even too long) can shorten life. Specifically, sleeping steadily less than 5 hours per night is linked to a significantly higher risk of mortality (up to ~40% higher) than sleeping 7-8 hours(Frontiers | Association of Sleep Duration With All-Cause and Cardiovascular Mortality: A Prospective Cohort Study). Sleeping more than 9-10 hours may also indicate underlying health problems and is associated with higher mortality(Frontiers | Association of Sleep Duration With All-Cause and Cardiovascular Mortality: A Prospective Cohort Study).

The optimal point for most people seems to be around 7 hours of good quality sleep per night.

In addition to duration, the circadian rhythm, i.e., our internal ~24-hour biological clock, matters. Modern habits such as evening use of electronic devices (blue light) or night shifts can confuse our internal clock, affecting metabolism and immune system. Regular circadian rhythms (falling asleep and waking up at about the same time, adequate exposure to natural light during the day and darkness at night) are linked to lower risk of depression, obesity, and even certain cancers.

The good news is that improving sleep is often possible with sleep hygiene tricks and without having to resort to medication. Creating a comfortable environment, following relaxing routines, and respecting your body’s signals can make a huge difference in the quality of rest.

In practice: Here are some tips for optimizing sleep and circadian rhythms:

Keep regular schedule: Try to go to bed and wake up at about the same time every day, including weekends. Regularity strengthens the circadian rhythm and improves sleep quality.
Light in the morning, dark in the evening: Exposing yourself to natural light in the morning (even going outside for 10 minutes as soon as you wake up is enough) helps “set” your biological clock. In the evening, on the other hand, limitexposure to blue light from phones, tablets, computers and TVs in the 1-2 hours before bedtime. If you must use them, reduce the brightness or use blue light filters.
Create a relaxing pre-sleep ritual: Practice a routine that signals to the body that it is time to sleep . It can include simple, pleasant gestures: take a warm bath or shower, read a few pages of a book (preferably on paper), practice 5 minutes of slow breathing or meditation, sip herbal tea (without caffeine).
Optimize the bedroom environment: The room should invite sleep. Keep the temperature cool (ideally around 18-20°C) and the room dark and quiet. If there are noises, consider earplugs or white noise in the background. A good mattress and pillow suitable for you make all the difference (we spend a third of our lives in bed!).
Be careful what you consume late in the day: Avoid caffeine in the 6 hours before bedtime (coffee, black tea, energy drinks). Also limit alcohol in the evening: it may give initial drowsiness, but it fragments sleep in the second part of the night. Very large evening meals can also disrupt rest; better to eat a light dinner and perhaps, if you are hungry before bed, have a light, healthy snack (such as a few almonds or a kiwi, which contains natural serotonin).

Social Connections: The Power of Relationships

Human beings are, by nature, social animals. The quality of our human relationships has a huge impact on health and longevity. Feeling loved, part of a community, having someone to count on in difficult times not only warms the heart – it also protects the body. In contrast,social isolation and chronic loneliness have been equated with serious health risk factors, similar to smoking 15 cigarettes a day in terms of their negative impact on longevity(Our Epidemic of Loneliness and Isolation). A meta-analysis that aggregated 148 studies found that having strong social relationships increases the odds of survival by 50 percent over the observation period compared to those who are socially isolated(Our Epidemic of Loneliness and Isolation). This effect is comparable to, if not greater than, many well-known biological risk factors! In practice, lack of social connectedness is an independent risk factor for mortality, on par with hypertension, smoking and obesity, while a good social network serves as a powerful protective factor.

But how do relationships physiologically affect our health? Several mechanisms have been identified. Emotional support from friends and family helps reduce stress (feeling understood lowers cortisol and blood pressure levels). Sharing time with others often involves physical or recreational activities that are good for you (from walking in the park with a friend to playing bocce ball at the senior club). In addition, those who are embedded in social ties tend to adopt healthy behaviors more easily — there is a kind of positive social contagion: in groups people tend to eat better, motivate each other to exercise or follow medical prescriptions. Not least, relationships stimulate the brain: conversing, confronting, even arguing and making up keep complex neural networks active and give “meaning” to our days.

In the world’s long-lived communities, the social aspect is central. In Okinawa, there is a tradition of “Moai”: small groups of friends who support each other throughout life, sharing joys and difficulties. Knowing that one is part of a close-knit group makes everyone feel constantly cared for and less worried about the future. In Sardinia, in the mountainous areas of Ogliastra where there is one of the highest rates of male centenarians, strong community cohesion, intergenerational living (grandparents, parents and grandchildren all close together) and a less hectic pace of life contribute to widespread serenity. In California, the Loma Linda community greatly emphasizes volunteerism, religious worship, and mutual support-this too creates shared purpose and bonds that improve health.

In practice: To build and maintain a social network that promotes longevity:

Dedicate time to loved ones: Put regular times for family and friends in your diary, as if they were important “appointments” (because they are!). It can be Sunday dinner with relatives, a weekly phone call to a distant friend, or an evening walk with a neighbor. Frequency matters: consistent contact fuels a sense of connection.
Cultivate community around you: Get involved in the life of your neighborhood or village. Join groups, associations, or collective activities that interest you-from volunteering at the soup kitchen, to a dance class, bocce team, or local hiking group. Meeting new people with common interests widens your network and keeps your sense of belonging alive.
Be present and listening: In interactions, try to be really present. Actively listen when someone is talking to you, show empathy, offer help if you can. The quality of relationships is built on trust and mutual support. Even offering a shoulder to cry on or helping a friend in need strengthens the bond (and also gives you a sense of usefulness and connection).
Make new connections, even late in life: It’s never too late to make friends. Talk to neighbors, chat with the bartender or other parents/grandparents at the park. Attend senior citizen social centers or senior citizen universities if you are retired-they are great places to socialize. Opening up to others sometimes takes some courage, but the benefits are worth the initial effort.
Surround yourself with people who encourage healthy habits: Companionship influences lifestyle. Whenever possible, hang out with people with whom you can share positive habits (such as walking together in the morning, or swapping healthy recipes, or going to see an exhibition instead of sitting at home in front of the TV all the time). Being part of a health-oriented “tribe” makes everything easier and more enjoyable.

Purpose and Meaning in Life

Having a purpose-knowing why you get out of bed in the morning-is a striking common denominator in the lives of the long-lived, and has emerged as a powerful predictor of health and resilience. The Japanese in Okinawa call this concept Ikigai, while Costa Ricans in Nicoya speak of plan de vida: in both cases it indicates the deep reason that gives meaning to one’s days. It can be the job you love, the family to care for, a social cause you believe in, a hobby you are passionate about, religious faith-or a combination of these things. Having a clear purpose is associated with lower stress levels, better health habits, and even measurable differences in biological markers of aging.

Scientific studies have sought to quantify the effect of purpose in life on longevity. In a study of more than 13,000 U.S. adults over 50, followed for 8 years, the group with a higher sense of purpose showed a significantly lower mortality risk: only 15% of them had died by the end of the period, compared to 36% mortality among those reporting a low sense of purpose(Higher Sense of Purpose May Be Linked to Mortality Risk | SPH). This was after adjusting for other factors: a sign that the “nurturing” of living with purpose has tangible effects on health. Another study suggested that the positive effect of having a life purpose may be particularly strong in women, but is present in both sexes and independent of ethnicity or class(Higher Sense of Purpose May Be Linked to Mortality Risk | SPH). Among possible reasons: those with goals and plans take better care of themselves, are more motivated to stay active and socially engaged, and physiologically have lower levels of inflammation and stress hormones.

In daily practice, finding purpose and meaning is not an abstract “philosophical” exercise, but something very concrete. It means identifying activities that give you joy and a sense of contribution, setting goals (small or large) that stimulate your personal growth, and recognizing the value of what you do for yourself and others. And purpose can evolve with the seasons of life: retirement, for example, may mean loss of work-related purpose for some, but it offers the opportunity to find a new one in volunteer work, grandchildren, and passions left in the drawer.

In practice: Here are some suggestions for cultivating or finding purpose in life, at any age:

Reflect on what makes you “lose track of time”: When do you enter that state of flow in which you are totally immersed and fulfilled? It may give you clues about authentic passions to cultivate (whether it’s writing, crafting, helping others, cooking…).
Put your talents to use for others: Everyone has unique skills or qualities. Share them! If you know how to do something (fix things, play music, teach a language, grow a garden), think about how you can put it to good use in the community. For example, mentor a young person in your profession, volunteer by teaching what you know, or even simply bake a cake for a neighbor: feeling useful fuels your purpose.
Try something new: Curiosity keeps you young. Sign up for that class you’re curious about, visit new places (even in your own city), read books on topics you don’t know. Keep your brain in learning mode: in addition to discovering interests you might be passionate about, keep your mind plastic and open.
Adjust purpose to life changes: Priorities in your 20s are different from those in your 70s. Don’t cling to a single identification (e.g., “my only reason for living is work” or “children”): cultivate different dimensions of you so that you always have some north star even when a phase closes (e.g., children grow up, you retire). Your purpose can evolve-from building a career, to giving something back to society, to passing on knowledge and wisdom to new generations. Each phase can have meaning if you actively seek it.
Connect purpose and daily well-being: Remember why you do what you do. For example, getting up to take a walk every morning may seem like a mundane routine, but if your purpose is “to keep myself healthy to watch my grandchildren grow up,” that walk becomes part of something bigger and more motivating. Find the common thread between your deep goals and the small actions of each day.

Environment and Prevention: Health Beyond Individual Lifestyle

When we talk about longevity, we often focus on personal choices, but there is a whole environment around us that can foster or hinder our health. Clean air, unpolluted water, green spaces and human-friendly cities are not just environmental issues-they are determinants of how long and well we live. For example,air pollution is now considered one of the leading outdoor killers: breathing air laden with fine particulate matter shortens the average lifespan. It is estimated that meeting WHO’s recommended limits on PM2.5 would lead to gaining about 2 more years of life on average worldwide(Air pollution can reduce life expectancy by almost 2 years- AQLI 2024 report – AQLI). In contrast, those living in the most polluted regions lose up to 2.7 years of life expectancy on average compared to those living in areas with cleaner air(Air pollution can reduce life expectancy by almost 2 years- AQLI 2024 report – AQLI). Air and environmental pollution in general increases the risk of cardiovascular disease, stroke, lung cancer, and respiratory disease. Protecting and improving the environment in which we live is therefore also a longevity strategy: policies to reduce emissions, sustainable traffic, clean energy, and proper waste management translate into years of healthy life gained for the population.

But the environment is not just air and water-it is also the urban and social environment. Living in a safe neighborhood, with walking options, parks where you can exercise, stores that are accessible on foot, efficient health services, all encourage healthy lifestyles and reduce stress and isolation. The “social climate” also matters: cohesive communities, where there is trust and mutual help, generate a sense of security and belonging that has positive effects on mental and physical health. In contrast, difficult socioeconomic conditions (poverty, crime, lack of services) are associated with worse health indicators and lower longevity. Italian data show differences in life expectancy between more advantaged regions and areas with greater socioeconomic hardship. Investing in public health – understood both as environmental protection and as social and health infrastructure – is therefore investing in the longevity of citizens.

Along with the environment, another crucial piece is preventive health care. An old adage states, “prevention is better than cure,” and never has this been truer than today thanks to advances in preventive and predictive medicine. According to some epidemiological estimates, up to80 percent of chronic diseases and premature deaths could be prevented by adopting healthy lifestyles and the proper preventive measures (no smoking, physical activity, balanced diet, control of risk factors)(Lifestyle as Medicine: The Case for a True Health Initiative – PubMed). Many forms of heart disease, stroke, type 2 diabetes and even cancer can also be largely prevented or delayed by primary (lifestyle) and secondary (screening and early detection) prevention.

Prevention means proactive action: taking care of one’s health before problems arise. This includes adhering to recommended screening programs (periodic examinations such as mammograms, Pap smears, colonoscopies, mole checks, etc., depending on age and personal risk factors) and vaccinations (annual flu for over 65 or frail, antipneumococcal, shingles, tetanus booster, and of course basic vaccinations). For example, colorectal cancer screening by occult blood detection and colonoscopy has been shown to significantly reduce mortality from this cancer through early removal of polyps; flu vaccination reduces the risk of serious complications and death in the elderly by 50%. Then there is “daily” prevention: measure blood pressure and keep cholesterol and blood sugar under control, take periodic blood tests, and seek medical attention at the first suspicious signs instead of waiting. The recent COVID-19 pandemic also taught the importance of simple gestures such as washing your hands, using a mask in crowded high-risk environments, and staying home when you are sick to protect yourself and others — these are all forms of prevention that save lives.

In practice (Environment): Each of us, in our own small way, can contribute to an environment conducive to longevity:

Reduce your footprint and protect the air: Use public transportation more, bike or walk whenever possible – not only will you reduce pollution (collective benefit), but you will get moving (personal benefit!). If you drive, try to carpool (carpool) or switch to an electric/hybrid vehicle if you can. Avoid burning trash or plastic material outdoors.
Healthy and safe home: Keep indoor spaces well ventilated (indoor air can be more polluted than outdoor air). If you live in a busy area, using indoor plants or small air purifiers can help filter out some substances. For the elderly: adapt the home environment to prevent accidents (fixed carpets, handrails and grab bars where needed, good lighting)-preventing falls means preventing disabilities.
Support green initiatives in your community: Participate in or support urban reforestation projects, community gardens, park and beach cleanups. Planting a tree today can provide oxygen and shade for decades. In addition, getting involved in these activities creates social bonds and gives satisfaction, two pro-longevity ingredients.
Create a positive climate around you: In your daily relationships, practice kindness, respect and mutual help. A “toxic” social environment of bickering and distrust breeds stress; conversely, supportive communities where people feel safe and supported encourage everyone to get out of the house, do activities, and live actively and positively. You too can be an agent of this change by cultivating good neighborhood relationships and participating in civic life (neighborhood meetings, local volunteering).

In Practice (Prevention): Make prevention an integral part of your lifestyle:

Don’t skip medical screenings: Find out from your doctor about recommended preventive screenings for your age group and risk factors (mammogram, Pap test, colorectal screening, mole check, urological examination, etc.). Put these appointments on your calendar as high a priority as a work commitment-they can literally save your life through early detection.
Keep up with vaccines: In addition to childhood vaccinations, remember those in adulthood. The annual flu shot is recommended for over 60 (and even younger people if they have chronic diseases); after age 65, it is indicated to vaccinate against pneumococcal (pneumonia) and shingles (shingles). These vaccines prevent diseases that can have serious complications in old age.
Regular check-ups and monitoring: Check in with your primary care physician at least once a year, even if you feel well, to measure blood pressure, do basic tests (blood, urine), and discuss any risk factors. Regular check-ups can uncover high blood pressure, pre-diabetes, or high cholesterol before they cause damage, so you can intervene in time (perhaps just improve diet and exercise, or start a little therapy).
Prevent accidents and protect your senses: Prevention is also avoiding harm: always use a seatbelt in the car and a helmet on a bike/motorbike, install smoke and monoxide detectors in the home, protect your skin from the sun with creams if you are outdoors for long periods of time. Also get regular checkups on vision and hearing: if you have vision or hearing declines, use glasses and hearing aids. For example, using hearing aids if you have hearing loss is associated with slower cognitive decline and an approximately 30-50% lower risk of dementia than those who do not correct their hearing loss ( What impact does hearing loss have on dementia risk? ). Don’t overlook these aids-they are part of healthy longevity.
Every day is prevention: Adopt the mindset that every small healthy choice is an act of prevention. Every cigarette less is prevention for your lungs and heart; every day you exercise is prevention for dozens of diseases; every night of good sleep is prevention for your brain and metabolism. This will help you value daily acts-they are never trivial, but building blocks of your future well-being.
