How to age well: which parts of a longevity routine actually hold up
If you have gone looking for how to age well, you have probably come away with a list of fourteen things to do before nine in the morning. Most of that list has never been tested against a health outcome. The parts that have are duller: total daily movement, two strength sessions a week, consistent sleep timing, and the checks your GP already does.
I am not against routines. I have one, and it is boring. What I am against is a routine you cannot check.
The women I sit with are not lazy and they are not uninformed. They are doing the sunlight, the breathwork, the ten thousand steps, the supplements someone sensible online suggested. Two years in, they have no idea whether any of it has done anything, because nothing in the routine was ever set up to be measured.
So here is the honest version. What has evidence behind it, what does not, and three things you can check this week for nothing.
The short version
- Australians are gaining years, and gaining years of poor health with them. A woman born now can expect about 73.8 years of full health out of 85.5.
- Most longevity routine advice has never been tested against a health outcome. That does not make it wrong. It makes it unverifiable, which is not the same thing.
- Total daily movement has the clearest evidence, and the benefit flattens well below ten thousand steps.
- Two days a week of strength work sits in Australia's own guidelines, and 76% of Australian women aged 18 to 64 do not do it.
- How regular your sleep is may matter more than how long it is.
- You can check where you stand this week without buying anything.
How to age well starts with a number nobody quotes
Australians are living longer, and that part is true.
Here is the part that rarely travels with it. The Australian Institute of Health and Welfare estimates that a male born in 2024 can expect 71.7 years of full health out of an average 81.6, and a female 73.8 out of 85.5. That is 88% and 86% of a life.
Against twenty years ago we have gained healthy years. We have also gained years spent unwell: 1.2 more for men, 1.5 more for women.
So when a routine promises you more years, ask which years. Nearly ten for a man and nearly twelve for a woman are already spent in poor health, and that is the part of the line worth arguing with. Not where it ends. What the last decade of it feels like.
That is also the honest job description for a healthy ageing routine. Not more years on the end. Fewer of them spent unwell.
Why most longevity routines cannot be checked
Try this on any piece of longevity advice you have saved. Three questions.
What is it supposed to change? By when? And how would I know if it did nothing?
Most of it fails on the first. "Supports cellular health" is not an outcome. Neither is "optimises your metabolism".
Some of it passes the first and fails the other two. Morning light genuinely shifts the timing of your body clock, and that part is well established. What nobody has run is a study of morning light against how long people stay well. Reasonable, then, and not proven at the level it gets quoted.
I am not telling you to stop anything. I am telling you to know which drawer a thing is in.
| What the routine says | What has actually been measured | What would tell you |
|---|---|---|
| Sunlight in the first 30 minutes | Light shifts the timing of the body clock. Nobody has tested morning light against long-term health | Your own bed and wake times over a fortnight |
| Ten thousand steps a day | 47,471 adults: risk falls with more steps, then flattens between 6,000 and 10,000 depending on age | Your phone's step count over one ordinary week |
| Cold exposure and breathing resets | Short-term shifts in heart rate and mood. Nothing followed over years | Nothing yet |
| A longevity supplement stack | 78 randomised trials, 296,707 people: antioxidant supplements did not lower deaths | Nothing yet |
| Two strength sessions a week | In Australia's own guidelines, and grip strength predicted death better than blood pressure across 139,691 people | Whether the two sessions happen, and whether they get easier |
What the walking research actually found
Ten thousand steps is the most repeated instruction in the category, and the researchers who finally tested it opened their paper by noting there was little evidence behind the number.
In 2022, fifteen research groups pooled their data: 47,471 adults wearing step counters rather than estimating, followed for a median of seven years, with 3,013 deaths.
They sorted everyone into four groups by daily steps. The least active quarter had a median of 3,553 steps a day. The most active had a median of 10,901.
Against the least active quarter, the risk of dying during follow-up was 40% lower in the second group, 45% lower in the third and 53% lower in the fourth.
Read the shape before the numbers. Almost all of the drop happens early, between about 3,500 steps and 6,000. After that the line bends, and keeps bending.
The researchers then modelled it as a curve rather than four blocks. Risk kept falling until 6,000 to 8,000 steps a day in adults aged 60 and over, and until 8,000 to 10,000 in adults under 60. Above that, nothing further was measurable.
There is a second finding in that paper, and it is the one I quote most often. Once total steps were accounted for, how fast people walked added nothing measurable. Minutes spent above 40 steps a minute, or above 100, made no significant difference.
The total is what showed up. Not the pace, and not a round number that got onto a poster.
One caveat, because it matters. This is observational, and people who walk a lot differ from people who walk little in ways no adjustment fully removes. Best evidence we have, still not a trial.
The two days a week most Australian women skip
Australia has updated its movement guidelines, and they now read like a day rather than a workout. Adults should be active most days. That means moderate to vigorous activity for 30 minutes or more on most days, muscle-strengthening on two or more days a week, work on mobility, balance and coordination on three or more days, and several hours of light activity daily.
Look at the second line.
Then look at what actually happens. In the 2022 national survey, 73% of Australians aged 18 to 64 did not do two days of muscle-strengthening activity in a week. Among women it was 76%.
Three quarters of us skip the one item that is in the national guidelines, while doing several that are in nobody's.
Here is what that evidence looks like. The PURE study measured grip strength in 139,691 adults across 17 countries and followed them for a median of four years. Every 5 kg less grip strength came with a 16% higher risk of dying in that window (hazard ratio 1.16, 95% confidence interval 1.13 to 1.20). Grip strength was a stronger predictor of death, and of cardiovascular death, than systolic blood pressure was.
Now the part most articles leave out, and it sits in the paper's own conclusion. The authors write that further research is needed to test whether improving strength reduces death. Grip strength is a very good marker, and nobody has yet shown that squeezing harder is the lever.
That distinction runs through this whole subject. A number that predicts something is not automatically a number you can push.
What I see in clinic. The routine is almost never the problem. The pattern I meet most often is a woman with an immaculate morning, a supplement shelf worth several hundred dollars, and a bedtime that moves by two and a half hours between Tuesday and Saturday.
She is doing the hard, visible, expensive parts and skipping the boring, free, invisible ones.
And when we go looking, there is usually something ordinary underneath as well. Ferritin nobody has checked in three years. A thyroid result called normal without anyone looking at the trend. A blood pressure taken once, at a chemist, in 2022.
None of that is a longevity secret. It is just the part with evidence, and it is unglamorous enough to get skipped.
Sleep, where the timing may beat the total
The same guidelines now carry a sleep line: 7 to 9 hours of good quality sleep, with consistent bed and wake up times. The second half of that sentence is newer than it looks.
In 2024 a team led from Monash University in Melbourne took accelerometer data from 60,977 UK Biobank participants, more than ten million hours of it, and scored how consistent each person's sleep timing was. Over roughly six years, 1,859 of them died.
The four most regular fifths of the group had 20% to 48% lower all-cause mortality than the least regular fifth. And sleep regularity predicted death better than sleep duration did.
If you have been chasing eight hours and getting them at wildly different times, that is the finding to sit with. Same bed time, same wake time, most nights, Saturday included.
It is also the cheapest change on this page, and the one people skip because it does not feel like doing something. If broken sleep is what brought you here, the wired-but-tired pattern is worth reading alongside it.
Where food fits, and where it does not
I am a nutritionist, so you would expect me to tell you food is the whole answer. It is not.
No single food, and no supplement, has been shown to add healthy years to a person's life. The largest attempt to test one class of them is worth knowing about. A Cochrane review pooled 78 randomised trials and 296,707 participants taking antioxidant supplements. Across the trials with the lowest risk of bias, deaths were slightly higher on the supplements than in the comparison groups, not lower (relative risk 1.04, 95% confidence interval 1.01 to 1.07). The increase sat with beta-carotene and vitamin E, and the authors concluded there was no evidence to support antioxidant supplements for prevention.
That is not an argument against nutrition, or against ever taking anything. It is an argument against taking things speculatively, for an outcome nobody is measuring.
Where food earns its place in a healthy ageing routine is duller. Enough protein to hold the muscle the strength work is building, enough fibre and plants for everything else, and checking the nutrients that actually run low in Australian women rather than the ones with the best marketing. Iron is the one I find most, and the one most often mistaken for just being tired. The micronutrient calculator will show you what a typical day of your food actually provides.
And if a biological age test looks like the way to score all this, the honest position is on our comparison of the biological age tests. They estimate. They do not tell you how long you have.
What to do this week
Three checks. None of them costs anything, and together they tell you more than a longevity panel would.
- Look at your steps for one ordinary week. Your phone has been counting whether or not you asked it to. Then hold the number against the range in the chart above, which is lower than you have been told.
- Note what time you got into bed and what time you got up, for fourteen nights. No app, the back of an envelope. The gap between your earliest night and your latest is roughly what the sleep study measured.
- Count your strength sessions over the last fortnight. Two a week is the guideline. If the answer is zero, that is the gap the guidelines actually ask you to close, and closing it costs nothing.
And one thing to book. If you are 45 or over, the 2023 Australian guideline says your cardiovascular risk should be assessed, and from 30 for Aboriginal and Torres Strait Islander people. It is an ordinary GP appointment: blood pressure, cholesterol, a diabetes check. It is the only item on this list where somebody else does the measuring.
Before you add anything else to the routine, ask yourself:
- What is this supposed to change, and by when?
- How would I know if it did nothing at all?
- Is there a duller, cheaper version of this that already has evidence?
- Am I doing the visible parts and skipping the boring ones?
- When did anyone last look at my bloods and my blood pressure in the same conversation?
That last one is where I would start. Most of what a longevity routine reaches for is already sitting in results somebody took and nobody read back to you. Further testing is for what stays unexplained after that.

Common questions
Is there any proven way to slow down ageing?
Not in the way the word usually gets used. No routine, food or supplement has been shown in a trial to slow biological ageing in people. What is well supported is that regular movement, muscle-strengthening work, consistent sleep and having blood pressure and cholesterol looked after are associated with more years lived in good health. That is a smaller claim, and it is the one the evidence actually makes.
Is 10,000 steps a day realistic?
For plenty of people, yes, but it is not the number the research landed on. Pooled data from 47,471 adults found the fall in risk stopped between 6,000 and 8,000 steps a day in adults aged 60 and over, and between 8,000 and 10,000 in adults under 60. If you are averaging 4,000, getting to 6,000 is where most of the benefit sits.
How does a woman age gracefully?
Ageing gracefully gets sold as a look, and the measurable version has very little to do with appearance. The parts with evidence behind them are total daily movement, two strength sessions a week, consistent sleep timing, not smoking, and having blood pressure, cholesterol and glucose checked on schedule. None of it photographs well. All of it shows up in the data.
What is the number one mistake that will make you age faster?
There is no single one, and any article that names one is guessing. The largest measurable risks in Australia are smoking, physical inactivity, high blood pressure and untreated high cholesterol or glucose. The everyday version I see most is subtler: doing the expensive, visible parts of a routine and skipping the free parts that have been tested.
What are the 5 pillars of healthy ageing?
Different organisations list different pillars, so read any set of five as a summary rather than a finding. If you want a version built only on what has been measured: move most days, do two strength sessions a week, keep your sleep timing consistent, and eat enough protein and plants. Then have your cardiovascular risk assessed from 45.
How many times should you be able to sit to stand in 30 seconds?
The published cut-offs for the 30-second chair stand were developed in adults aged 60 and over, so if you are in your forties there is no validated score to hold yourself against. What is still useful is the direction. Do it today, write the number down, and do it again in three months. Your own trend tells you more than somebody else's threshold.
