A tech entrepreneur publicly documents his regimen of dozens of daily pills. A podcast host swears by cold plunges and a supplement stack. Your feed pushes a pricey test to reveal your "biological age". Longevity has become an industry, but the question most of us actually care about is simpler: how to increase healthspan, the number of years you live in good health, able to do the things you enjoy.
The honest answer is that the best-proven levers are unglamorous and mostly free: not smoking, moving often, building strength and fitness, eating mostly whole foods, sleeping well, keeping alcohol low, staying connected to people and catching problems like high blood pressure early. We make supplements at TANO and would still rank them well below all of that: our Daily Wellness Trio exists to make a few daily basics easier, not to replace them.
Key takeaways
- Lifespan is how long you live; healthspan is how long you live well. WHO data shows a global gap of roughly ten years between the two.
- In a large Harvard analysis, adults with five healthy habits at age 50 had about 12–14 more years of life expectancy than those with none.
- Cardiorespiratory fitness and muscle strength are among the strongest predictors of healthy ageing.
- Popular longevity supplements such as NMN and resveratrol lack convincing evidence of extending healthy life in humans.
- Regular screening for blood pressure, blood sugar and cholesterol is one of the highest-value, lowest-effort habits, especially in Malaysia.
What is healthspan, and why does the gap matter?
The WHO tracks both life expectancy and "healthy life expectancy", the average number of years lived in full health. According to WHO estimates, global life expectancy rose from 66.8 years in 2000 to 73.4 in 2019, while healthy life expectancy rose from 58.3 to 63.7 years. In other words, the average person spends around a decade at the end of life living with illness or disability.
Healthspan is about shrinking that gap: staying independent, mobile and mentally sharp for as long as possible. That is a more useful goal than simply adding years, and it is also where the evidence is strongest.
What does the evidence say actually adds healthy years?
Two large analyses from Harvard T.H. Chan School of Public Health, drawing on decades of data from more than 100,000 US adults, are among the clearest we have.
The first, published in Circulation in 2018, looked at five low-risk habits: never smoking, a healthy weight, at least 30 minutes a day of moderate-to-vigorous activity, a high-quality diet and moderate alcohol intake. At age 50, women who followed all five had an estimated 14 more years of life expectancy than women who followed none; for men it was about 12 years.
The second, published in The BMJ in 2020, asked the healthspan question directly. Women who followed four or five of these habits at 50 lived around ten more years free of diabetes, heart disease and cancer than those who followed none; for men, the gain was nearly eight years.
One caveat worth stating plainly: "moderate alcohol" was counted as low-risk in those studies, but more recent research and the WHO's position are that no level of drinking is actually beneficial for health. If you don't drink, there is no reason to start.
How to increase healthspan: the levers, ranked by evidence
| Lever | Strength of evidence | What to do |
|---|---|---|
| Not smoking or vaping | Very strong | Quit, with support if needed. The WHO estimates tobacco kills up to half of its users. |
| Physical activity and fitness | Very strong | 150–300 minutes of moderate activity weekly, plus some harder efforts that raise your heart rate. |
| Muscle strength | Strong | Strength training at least twice a week. |
| Blood pressure, sugar and cholesterol control | Very strong | Get screened regularly; treat what you find. |
| Diet quality | Strong | Mostly vegetables, fruit, whole grains, legumes, fish; fewer sugary drinks and processed meats. |
| Sleep | Moderate to strong | Seven to nine hours for most adults, on a regular schedule. |
| Social connection | Moderate to strong | Invest in regular contact with friends, family and community. |
| Longevity supplements (NMN, resveratrol, etc.) | Weak in humans | Treat as experimental; don't let them replace the basics. |
Why fitness and muscle deserve special attention
If there's one area where "longevity" content has a point, it is fitness. A 2018 study in JAMA Network Open of more than 120,000 adults who took treadmill tests at Cleveland Clinic found that low cardiorespiratory fitness was associated with a higher risk of death than well-known risk factors such as smoking and diabetes, and that the benefit of higher fitness showed no upper limit.
Muscle matters too, because it protects against falls, frailty and blood sugar problems. We explain why in strength training after 30. A practical mix: brisk walking or cycling most days, one or two sessions a week that make you breathe hard, and two strength sessions.
Is social connection really a health habit?
Yes, and it is routinely underrated. A widely cited 2010 meta-analysis in PLOS Medicine, covering 148 studies and more than 300,000 people, found that people with stronger social relationships had a 50% greater likelihood of survival over the study periods. The authors compared the size of the effect to well-established risk factors such as smoking.
For many in Southeast Asia, this is where culture helps: the regular family dinner, the kopitiam catch-up, the WhatsApp group that actually meets up. Protect those, especially in busy decades when work tends to crowd them out.
What about longevity supplements and biohacks?
Here is where the hype outruns the science:
- NMN and NR (NAD+ precursors) raise NAD+ levels in blood, and some show promising effects in animals. Human trials so far are small and short, and none show that they extend healthy life.
- Resveratrol, once the star of "red wine longevity" headlines, has largely disappointed in human studies.
- Metformin and rapamycin are prescription drugs being studied for ageing. Taking them without medical supervision is not advisable.
- Biological age tests are interesting research tools, but different tests can give different answers for the same person, and it isn't yet clear how to act on the results.
Supplements do have a role when they fill a genuine gap, such as low vitamin D or iron. Our guide to building a supplement routine that makes sense covers where they fit. They just aren't the main event.
A healthspan checklist for your 20s, 30s and 40s
- Know your numbers. Blood pressure yearly; blood sugar and cholesterol as advised by your doctor. Malaysia's National Health and Morbidity Survey 2019 estimated that around 30% of adults had high blood pressure and around 18% had diabetes, and a large share didn't know it.
- Move daily, sweat weekly, lift twice a week.
- Build meals on plants and protein, and rethink sugary drinks.
- Protect sleep. If your nights are short, start with why we sleep too little and how to win it back.
- Don't smoke or vape; keep alcohol low.
- Schedule people the way you schedule meetings.
- Look after your hearing, eyes and teeth. Hearing loss, for example, is increasingly recognised as a modifiable risk factor for dementia.
Where TANO fits: the Daily Wellness Trio
Nothing in a tube will add healthy years the way the levers in the table above can. Sleep, movement, food and not smoking do the heavy lifting. We built the Daily Wellness Trio for a smaller, everyday job: making a few nutrition basics simple enough that you actually keep them up.
- THRIVE: per 2-tablet serving, 800 mg vitamin C and 16 mg zinc, which contribute to normal immune function, plus 20 mg iron, 100 mcg selenium, B vitamins and a 1.6 g greens blend. A top-up, not a replacement for vegetables.
- GLOW: 2,000 mg collagen peptides, 500 mg glutathione, 80 mg hyaluronic acid, 400 IU vitamin D and 80 mg vitamin C, which contributes to normal collagen formation. Collagen studies often use 2.5–10 g, so this is a modest daily dose.
- IGNITE: 1,000 mg apple cider vinegar, 1,000 mg garcinia cambogia fruit, 200 mg pomegranate and vitamins B6 and B12, as a zero-sugar drink in place of a sweet one.
Each is 2 tablets in 250–500 ml cold water, once daily. All are halal-certified and zero sugar. THRIVE and IGNITE together add about 1.3 g sodium, worth knowing if you watch your salt.

Frequently asked questions
What is the difference between lifespan and healthspan?
Lifespan is the total number of years you live. Healthspan is the number of those years spent in good health, free from serious disease or disability. WHO estimates suggest people globally spend about a decade of life in less than full health.
Can TANO's Daily Wellness Trio help you live longer?
No supplement, ours included, has been shown to extend healthy life, and we don't claim it. The Trio (THRIVE, GLOW and IGNITE) is a food supplement set that helps you cover some everyday nutrients, such as vitamin C and zinc, which contribute to normal immune function. The habits in this article, especially activity, strength, sleep, diet and not smoking, are what the evidence links to more healthy years.
How can I increase my healthspan?
The best-supported ways are not smoking, regular physical activity including strength training, a diet rich in whole plant foods, adequate sleep, low alcohol intake, strong social connections and regular health screening. Harvard research found five healthy habits at age 50 were linked to 12–14 extra years of life expectancy.
Do NMN or NAD+ supplements slow ageing?
There is currently no convincing evidence in humans that NMN or other NAD+ boosters slow ageing or extend healthy life. Studies so far are small and short-term. They should be viewed as experimental.
Is it too late to improve healthspan in my 40s or 50s?
No. The Harvard analyses measured the benefit of healthy habits from age 50, and studies show fitness and strength improve at any age. Quitting smoking, becoming more active and managing blood pressure all pay off in midlife and beyond.
What single habit matters most for healthy ageing?
If you smoke, stopping is the biggest single step. For non-smokers, regular physical activity that builds both fitness and strength is arguably the most powerful lever, because it affects heart health, blood sugar, mood, sleep and independence in later life.
