Healthy Aging: An Evidence-Based Daily Routine for Longevity

Healthy aging is built from daily habits, not a single hack

If you are somewhere between 35 and 65, healthy aging can feel like a moving target surrounded by marketing noise. The good news: the science points to a short list of genuinely powerful, unglamorous habits. None of them are secret, and none of them require a lab. What follows is an evidence-based daily routine organized around five pillars: move, eat, sleep, recover, and connect. Supplements come last, on purpose, because they are the smallest lever of the bunch.

A quick note before you change anything: talk with your healthcare provider before starting a new exercise program or supplement, especially if you have an existing condition or take medication.

Morning: move your body and eat like you mean it

Pillar 1 — Move (the biggest lever)

Physical activity is the most consistently supported habit for aging well. General guidance from public health authorities points to at least 150 minutes of moderate aerobic activity per week, plus muscle-strengthening activity on two or more days. Aerobic work supports cardiovascular and metabolic health; resistance training supports something that quietly erodes with age — muscle.

After roughly age 40, adults gradually lose muscle mass and strength, a process that accelerates later in life. Resistance training is the most direct way to push back, supporting strength, mobility, bone density, and everyday independence. If you do only one new thing this year, add two short strength sessions a week. For a deeper look at why this matters, see our guide on preventing sarcopenia and muscle loss after 50.

One simple, trackable marker of overall resilience is grip strength, which researchers use as a proxy for whole-body strength and healthy aging. Our article on grip strength and longevity explains how to measure and build it. And if you want to understand how exercise and timing interact with your cells, our piece on fasting, exercise, and mitophagy covers how movement helps your body clean up worn-out cellular components.

Pillar 2 — Eat (protein and plants)

You cannot out-supplement a poor diet, and you cannot maintain muscle without enough protein. As we age, the body becomes less efficient at using dietary protein to build and preserve muscle, which is why many nutrition researchers suggest older adults aim toward the higher end of protein intake and spread it across meals rather than loading it all at dinner. Pair that with a mostly plant-forward pattern rich in vegetables, fruit, legumes, whole grains, nuts, and healthy fats, and you have covered most of what the evidence supports.

Practical starting points: build each meal around a protein source, fill half your plate with vegetables, and lean toward minimally processed foods most of the time. Hydration and fiber help too, and they are easy to overlook.

Daytime: sunlight, movement snacks, and sun protection

Long stretches of sitting work against everything you do in the gym. Break up the day with short "movement snacks" — a few minutes of walking, stairs, or bodyweight squats every hour or so. Getting some daylight, particularly in the morning, also supports your circadian rhythm, which feeds directly into better sleep that night.

At the same time, protect your skin. Daily use of broad-spectrum sun protection is one of the most under-appreciated healthy-aging habits, supporting skin health and reducing sun damage over the decades. It costs almost nothing and takes seconds.

Evening: sleep and recovery

Pillar 3 — Sleep

Sleep is when your body does much of its repair and consolidation work. Most adults do best with 7-9 hours of consistent, quality sleep. Short-changing it affects mood, appetite regulation, focus, and how well you recover from training. A regular schedule, a cool and dark room, and a wind-down routine that limits late-night screens and heavy meals go a long way.

Pillar 4 — Recover and manage stress

Chronic, unmanaged stress works against healthy aging. You do not need an elaborate system — a few minutes of daily breathing practice, time outdoors, or a hobby that absorbs your attention can help support a calmer baseline. Recovery days between hard workouts are part of the plan, not a break from it.

Pillar 5 — Connect and don't smoke

Two of the best-supported longevity habits are almost never sold as supplements: avoiding tobacco and maintaining strong social connections. Not smoking (and avoiding vaping) is among the single most impactful choices for long-term health. And robust research on social ties links connection and community to healthier aging. Schedule the call, keep the standing walk with a friend, stay involved.

Plant-forward, whole-food eating	Supports overall nutrition and healthy aging	Fill half your plate with vegetables
7-9 hours of consistent sleep	Supports recovery, mood, and cognition	Fixed bedtime and a screen-light wind-down
Stress management	Supports a calmer physiological baseline	5 minutes of breathing or a daily walk outdoors

Social connection	Associated with healthier aging	One meaningful interaction each day
No tobacco	Among the most impactful long-term choices	If you smoke, ask your provider about quitting support

Where supplements fit — honestly

Once the foundations above are consistent, some people choose to add a targeted supplement or two. Think of this as the last few percent, not the strategy. No pill replaces training, protein, sleep, or not smoking.

One compound that has drawn research interest for aging-related cellular health is Urolithin A, a metabolite the gut produces from certain polyphenols found in foods like pomegranates, berries, and walnuts. Not everyone's gut microbiome makes meaningful amounts of it, which is part of why it is studied as a direct supplement. It has been examined for its potential to support mitophagy — the body's process of recycling aging mitochondria — and mitochondrial function.

In a randomized study published in Cell Reports Medicine (2022), Urolithin A supplementation was associated with improvements in muscle endurance and markers of mitochondrial health in middle-aged adults (see the study). More recent work published in Nature Aging (2025) has continued to explore Urolithin A in the context of aging biology (read here). This research is promising but still developing, and it describes structure/function support for cellular energy — not treatment or prevention of any disease.

If you want to learn more about the compound itself, our overview of Urolithin A benefits goes deeper. For those who have their fundamentals in place and want to try it, SOMA offers Urolithin A 1,000mg gummies as a convenient daily option. As with any supplement, check with your healthcare provider first, especially if you are pregnant, nursing, or taking medication.

Frequently asked questions

What is the single most important habit for healthy aging?

If forced to pick one, most experts point to regular physical activity that includes both aerobic exercise and resistance training. Movement supports nearly every system involved in aging well — muscle, bone, heart, metabolism, and brain. That said, the habits work together; sleep and nutrition make your training more effective.

How much protein do I actually need as I get older?

Needs vary by body size, activity, and health status, but many nutrition researchers suggest older adults aim toward the higher end of general protein recommendations and spread intake across meals to better support muscle maintenance. A registered dietitian or your healthcare provider can help you set a specific target.

Do I need supplements to age well?

No. The daily habits in this article — movement, nutrition, sleep, stress management, not smoking, and social connection — do the vast majority of the work. Supplements are an optional layer for people who already have the basics covered and want to add targeted support.

What does Urolithin A do?

Urolithin A is a gut-derived metabolite studied for its potential to support mitophagy and mitochondrial function, which relate to cellular energy. Research including a 2022 Cell Reports Medicine trial has examined its effects on muscle endurance and mitochondrial markers. It is studied for structure/function support, not as a treatment for any condition.

Is it ever too late to start?

No. Research consistently shows that adopting these habits provides benefits at essentially any age, including for adults starting strength training in their 50s, 60s, and beyond. Start with one or two changes, make them consistent, and build from there — after checking with your healthcare provider.
