The short answer
The longevity habits with the strongest evidence are not secret hacks. They are regular movement, some strength training, a mostly whole-food diet, 7 or more hours of sleep, not smoking, drinking less alcohol, staying socially connected and keeping up with checkups. In a large Harvard analysis, adults who kept five basic habits had a projected life expectancy at age 50 about 12 to 14 years longer than adults who kept none.
- Move: about 150 minutes a week of moderate activity, per the CDC.
- Lift: muscle-strengthening work at least 2 days a week.
- Sleep: 7 or more hours a night for most adults.
- Know your numbers: blood pressure, cholesterol, blood sugar and weight, the core of the American Heart Association’s Life’s Essential 8.

Most people want two things from aging: more years, and more good years. Longevity habits, the everyday behaviors linked in long-term studies to living longer and staying healthier, are the most reliable tools we have for both. Better still, they are ordinary. The National Institute on Aging (NIA), the federal research agency for aging, lists staying active, eating well, sleeping enough, limiting alcohol, not smoking, staying connected and seeing a doctor regularly as the core steps, as its healthy aging research summary explains.
In short, this guide replaces our earlier version of this article. Instead of chasing biohacks, it sticks to what large studies and US health agencies actually show, with numbers you can check. It is written for adults of any age, although the payoff tends to grow the longer you keep a habit.
What are longevity habits?
Longevity habits are repeatable daily choices that lower your risk of the chronic diseases that shorten life, mainly heart disease, stroke, type 2 diabetes and several cancers. In other words, they work by preventing or delaying illness, not by changing how fast your cells age in some measurable way.
Because chronic disease builds slowly, the habits matter most when you keep them for years. That said, research also shows real benefits from starting late. For example, the NIA notes that people who quit smoking between 45 and 54 lived about six years longer than those who kept smoking, and those who quit between 55 and 64 lived about four years longer.
Which longevity habits matter most?
If you only focus on a few, start with the ones that have the biggest and most consistent effects in the research: not smoking, regular physical activity, a good-quality diet, healthy weight and blood pressure, and enough sleep. Social connection and screenings round out the list, since loneliness and undetected disease both raise risk.
Lifespan vs healthspan: what is the difference?
Lifespan is how long you live; healthspan is how many of those years you live in good health, free of serious disease or disability. To track it, researchers measure healthspan with a statistic called health-adjusted life expectancy.
However, the gap between the two is large in the US. A 2024 Mayo Clinic analysis of World Health Organization data for 183 countries, published in JAMA Network Open, found the US had the widest healthspan-lifespan gap of any country studied, at 12.4 years. Notably, the authors linked that gap to a rise in noncommunicable diseases such as heart disease and diabetes.
| Lifespan | Healthspan | |
|---|---|---|
| What it measures | Total years lived | Years lived in good health |
| How it is tracked | Life expectancy | Health-adjusted life expectancy |
| US gap between them | About 12.4 years | About 12.4 years |
| Main drivers | Accidents, disease, genetics | Chronic disease, disability, mobility |
So healthspan is the more useful target. Fortunately, the same longevity habits that lower your risk of early death also tend to keep you mobile and independent for longer.
How much can healthy habits add to your life?
Large observational studies suggest the combined effect of a few basic habits is measured in years, not months. For example, the best-known study is a 2018 Harvard study in Circulation that followed more than 120,000 US health professionals for up to 34 years.
In that study, the five low-risk habits were never smoking, a body mass index (BMI, a weight-to-height ratio) of 18.5 to 24.9, at least 30 minutes a day of moderate to vigorous activity, moderate alcohol intake and a high-quality diet. As a result, women with all five had a projected life expectancy at age 50 about 14 years longer than women with none, and men gained about 12 years.
| Study | What it looked at | Key finding |
|---|---|---|
| Li et al., Circulation 2018 | 5 low-risk lifestyle habits in US adults | About 14.0 more years at age 50 for women and 12.2 for men with all 5 vs none |
| Ma et al., Circulation 2023 | Life’s Essential 8 scores in 23,003 US adults | High scores linked to about 8.9 more years of life expectancy at 50 vs low scores |
| Momma et al., BJSM 2022 | Muscle-strengthening activity, 16 cohort studies | 10% to 17% lower risk of death from all causes, heart disease and cancer |
| Holt-Lunstad et al., PLoS Med 2010 | Social relationships, 148 studies | 50% higher likelihood of survival with stronger social ties |
| NIA summary of step research | Daily steps in adults 40 and older | 8,000 steps vs 4,000 linked to 51% lower risk of death |
Watch out. Studies like these compare groups of people, so they cannot promise any individual a set number of extra years. In addition, genetics, income, access to care and existing health conditions all play a role too.
What is Life’s Essential 8?
Life’s Essential 8 is the American Heart Association’s checklist of eight measures of heart and brain health: four behaviors and four health numbers. The AHA first introduced it in 2022, adding sleep to its earlier list of seven, in an advisory published in Circulation.
Each measure gets a score from 0 to 100, and the average is your overall score. In the 2023 study above, scores under 50 counted as low, 50 to 79 as moderate and 80 or more as high. Therefore, it works well as a practical longevity scorecard.
| Measure | Ideal level for adults (100 points) |
|---|---|
| Diet | Close adherence to a DASH-style or Mediterranean-style eating pattern |
| Physical activity | 150 or more minutes a week of moderate or vigorous activity |
| Nicotine exposure | Never smoked |
| Sleep | 7 to under 9 hours a night |
| Body mass index | Under 25 |
| Non-HDL cholesterol | Under 130 mg/dL |
| Blood sugar | No diabetes and fasting glucose under 100 mg/dL (or HbA1c under 5.7%) |
| Blood pressure | Under 120/80 mm Hg |
Pro tip. You do not need a perfect score to benefit. Moving any one measure in the right direction counts, and your doctor can check the four numbers at a routine visit.
8 healthy habits to live longer
Here are the eight longevity habits with the most consistent support from US health agencies and long-term research. Next, each card shows what to aim for and where the guidance comes from.
1. Move most days
Regular aerobic activity is one of the strongest longevity habits. The CDC adult guidelines call for about 150 minutes a week of moderate activity, such as brisk walking, or 75 minutes of vigorous activity like jogging.
- Why it matters: the CDC links regular activity to lower risk of heart disease, stroke, type 2 diabetes and at least eight types of cancer.
- Steps: CDC says the risk of early death leveled off at about 8,000 to 10,000 steps a day for adults under 60, and 6,000 to 8,000 for those 60 and older.
- Start small: even 10 extra minutes a day makes a difference, according to the CDC.
Walking also counts, and it is often the easiest place to start. For a deeper comparison, our guide to walking vs running compares the two for weight and joint health.
2. Train your muscles twice a week
Strength training helps you keep muscle as you age, and muscle helps you stay independent. The CDC recommends muscle-strengthening activities that work all major muscle groups on at least 2 days a week.
- Evidence: a 2022 meta-analysis found muscle-strengthening activity was linked to a 10% to 17% lower risk of death from all causes, heart disease and cancer.
- How much: the biggest risk reduction appeared at about 30 to 60 minutes a week; the benefit of much more was unclear.
- Muscle and age: in a UCLA study of older adults, those with the most muscle relative to height had about 20% lower risk of death than those with the least.
3. Eat mostly whole foods
Diet quality also shows up in almost every longevity study. The Dietary Guidelines for Americans, 2025 to 2030 emphasize vegetables, fruits, protein foods, dairy, healthy fats and whole grains, and a sharp cut in highly processed foods and added sugars.
- Patterns with evidence: the NIA highlights Mediterranean-style, DASH and MIND eating patterns for heart and brain health.
- Limit: sugar-sweetened drinks, highly processed snacks and sodium (under 2,300 mg a day for people 14 and older).
- Protein: the new guidelines set a goal of 1.2 to 1.6 grams per kilogram of body weight a day; ask your doctor what fits you, especially with kidney disease.
Fiber and fermented foods also support the gut microbiome, the bacteria living in your digestive tract. If you want specifics, our gut health food guide covers which foods help most.
4. Protect your sleep
Sleep is now formally part of heart health, too. The CDC says adults 18 to 60 need 7 or more hours, adults 61 to 64 need 7 to 9 hours and adults 65 and older need 7 to 8 hours.
- Why it matters: too little sleep is linked to higher risk of type 2 diabetes, heart disease, high blood pressure and stroke, plus more car crashes.
- Dementia link: the NIA cites a study of nearly 8,000 people where those sleeping 6 hours or less in their 50s and 60s had a higher dementia risk later.
- Best habit: a steady sleep and wake time every day, per the NIA.
If you struggle to fall or stay asleep, see our sleep tips for busy professionals.
5. Do not smoke or vape
Not smoking is the single habit present in every major longevity framework. According to the CDC, quitting can add as much as 10 years to life expectancy and helps at any age.
- Timeline: heart attack risk drops sharply within 1 to 2 years of quitting, per the CDC.
- Long term: after 15 years, coronary heart disease risk approaches that of someone who never smoked.
- Help works: your doctor can discuss counseling and FDA-approved quit medicines.
6. Drink less alcohol
Alcohol advice has become more cautious. The 2025 to 2030 Dietary Guidelines simply say to consume less alcohol for better overall health, and they no longer give daily drink limits.
- Avoid completely: during pregnancy, in recovery from alcohol use disorder, if you cannot control your drinking, or with medicines or conditions that interact with alcohol.
- Older study note: the 2018 Harvard study counted moderate drinking as low risk, but current guidance does not suggest starting to drink for health.
- Aging: the NIA notes that older adults are more vulnerable to the effects of alcohol.
7. Stay connected
Relationships matter for survival about as much as some classic risk factors. A meta-analysis of 148 studies found that people with stronger social ties had a 50% higher likelihood of survival over the study periods.
- Risks of isolation: the CDC links loneliness and isolation to heart disease, stroke, type 2 diabetes, depression, dementia and earlier death.
- How common: about 1 in 3 US adults report feeling lonely, according to CDC data.
- What helps: regular calls or visits, classes and volunteering, as the NIA suggests.
Stress management belongs here too, since chronic stress affects sleep, mood and heart health. For practical steps, our guide on how to reduce stress lists techniques with evidence behind them.
8. Keep up with checkups and screenings
Many longevity risks are silent, so testing matters. For example, the CDC notes that most people with high blood pressure have no symptoms, so measuring it is the only way to know.
- Colorectal cancer: screening for average-risk adults 45 to 75, per the CDC and USPSTF.
- Breast cancer: a mammogram every two years for average-risk women 40 to 74, per the USPSTF.
- Lung cancer: yearly low-dose CT for adults 50 to 80 with a heavy smoking history who smoke now or quit within 15 years, per the CDC.
- Numbers to know: blood pressure, cholesterol, blood sugar and weight, the four Life’s Essential 8 health factors.

How to build longevity habits that last
Habits stick when they are small, specific and tied to something you already do. For instance, walk for 10 minutes after lunch, keep resistance bands next to the TV, or set a fixed bedtime alarm. Then add one change at a time, because stacking five new rules at once is the fastest way to drop all of them.
What the research does not support yet
Much of the online longevity world runs ahead of the evidence. So here is an honest look at claims that often appear alongside real longevity habits, including in the earlier version of this article.
| Popular claim | What the evidence shows |
|---|---|
| Very high protein intake slows aging | Current US guidelines set a goal of 1.2 to 1.6 g/kg a day; we found no agency guidance supporting much higher amounts for longevity. |
| Exercise works as a senolytic or lengthens telomeres | These are active research areas, mostly in lab and small studies; they are not proven ways to extend human life. |
| Time-restricted eating switches off aging via mTOR | Animal research is intriguing, but human longevity evidence is not established. |
| One test, like grip strength, predicts your future | Grip strength and muscle mass are linked to outcomes in studies, but no single measure tells your personal future. |
| Supplements can extend lifespan | No supplement has been shown to extend human lifespan; talk to your doctor before taking any. |
Similarly, weight-loss drugs can improve some risk factors, yet they are medical treatments, not lifestyle shortcuts. If you are curious, our GLP-1 drug explainer covers what they do.
A simple week of longevity habits
A realistic week can cover every habit without a gym membership or special foods. Here is one example, so adjust it to your schedule and any advice from your doctor.
| Day | Movement | Other habit |
|---|---|---|
| Monday | 30-minute brisk walk | Plan three home-cooked dinners |
| Tuesday | 20 to 30 minutes of strength work (squats, push-ups, bands) | Same bedtime as Monday |
| Wednesday | 30-minute brisk walk | Call a friend or family member |
| Thursday | 30-minute walk or bike ride | Swap a soda for water |
| Friday | 20 to 30 minutes of strength work | Check whether any screenings are due |
| Saturday | Longer walk, hike or active outing with others | Cook a vegetable-heavy meal |
| Sunday | Rest or gentle stretching | Review the week and pick one habit to improve |
When to see a doctor
See a doctor before starting a new exercise plan if you have heart disease, diabetes, kidney disease or another chronic condition, or if you have been inactive for a long time. Otherwise, get regular checkups so silent problems like high blood pressure are found early. In addition, make an appointment soon if you notice:
- Chest pain, pressure or shortness of breath with activity
- Fainting, dizziness or a racing or irregular heartbeat
- Unexplained weight loss, ongoing fatigue or new pain that will not go away
- Loud snoring with pauses in breathing or daytime sleepiness
- Low mood, loss of interest in activities or feeling isolated for weeks
- Trouble controlling how much you drink
Call 911 right away for chest pain that lasts more than a few minutes, sudden weakness or numbness on one side, trouble speaking or sudden severe headache.
Our verdict
The best longevity habits are boring, and that is good news. Move about 150 minutes a week, lift twice a week, eat mostly whole foods, sleep 7 or more hours, skip tobacco, drink less, stay connected and keep up with screenings. Together, these habits are linked to many more healthy years in large US studies.
Pick one habit this week, make it small enough to keep, and build from there. After all, consistency over years matters far more than any trend.
Frequently asked questions
What are the best longevity habits?
The best supported longevity habits are not smoking, regular physical activity, strength training twice a week, a diet built mostly on whole foods, 7 or more hours of sleep, drinking less alcohol, staying socially connected and getting recommended screenings. In fact, these match the American Heart Association Life’s Essential 8 and NIA healthy aging advice.
How many years can healthy habits add to your life?
In a 2018 Harvard study of US adults, people with five healthy habits had a projected life expectancy at age 50 about 14 years longer for women and 12 years longer for men than people with none. These are group averages from observational data, so individual results vary.
Is it too late to start healthy habits at 50 or 60?
No. Benefits appear at any age. For example, the NIA reports that people who quit smoking between 55 and 64 lived about four years longer than those who kept smoking, and exercise helps older adults maintain muscle and function. Talk to your doctor before starting a new exercise plan.
What is the difference between lifespan and healthspan?
Lifespan is the total number of years you live, while healthspan is the number of years you live in good health without serious disease or disability. Notably, a 2024 study found the US has the largest gap between the two among 183 countries, at about 12.4 years.
How many steps a day help you live longer?
CDC research summaries say the risk of early death leveled off at about 8,000 to 10,000 steps a day for adults under 60 and about 6,000 to 8,000 for adults 60 and older. Any increase from a low baseline still helps, so start where you are.
Do supplements help you live longer?
No supplement has been shown to extend human lifespan. Some people need specific nutrients, such as vitamin D or iron, based on testing or diet, but that is a medical question. Ask your doctor before taking supplements, since some interact with medicines.
