How you care for yourself at this life stage matters a lot for your later years
How you treat your body and brain in your midlife years, loosely defined as 40 to 60, can hugely influence how you age in the decades to come.
The seeds for many age-related diseases, including cardiovascular disease, diabetes, cancer and dementia, are sown in middle age, so it’s important to start thinking about prevention early. And it takes a lifetime of healthy habits, not just a few weeks, to move the needle on your longevity.
“Midlife is the ideal time to make changes, not only to benefit you in the present, but also in the future,” said Margie Lachman, a psychology professor at Brandeis University and the author of “Primetime: A New Vision for Midlife.”
After all, she added, “What happens in midlife doesn’t stay in midlife.”
We spoke with experts about some small habits that can make a big difference.
1. Do interval training.
Cardio-respiratory fitness is one of the best predictors “of longevity and being able to be active and mobile in the later years of your life,” said Dr. Guillem Gonzalez-Lomas, an associate professor of orthopedic surgery at New York University’s Grossman School of Medicine.
One way to improve your cardio-respiratory fitness is to incorporate interval training into your workouts a few times a week, Dr. Gonzalez-Lomas said.
For example, rather than logging 30 minutes on a treadmill or a stationary bike at a steady pace, try alternating sprinting for 30 seconds and then resting for 30 seconds, 10 times through. It will be a shorter workout, but ideally also a harder one, because to get the biggest benefit, “You actually have to really push yourself,” he said.
2. Run errands with a friend.
Several experts emphasized the importance of social relationships for people’s long-term health and well-being.
People often “don’t think of social interaction as a wellness intervention,” said Dr. Ezekiel Emanuel, a professor of medical ethics and health policy at the University of Pennsylvania Perelman School of Medicine and the author of “Eat Your Ice Cream: Six Simple Rules for a Long and Healthy Life.” But it may be “the most important wellness intervention,” he said.
The reality of midlife is that it can be hard to carve out time for yourself, let alone coordinate schedules with another busy friend. Dr. Lachman suggested taking a “two birds, one stone” approach and joining up with someone to complete tasks on your to-do lists. Those could include going for a walk or a workout together or even a trip to the grocery store.
3. Eat fermented foods.
When you’re thinking about the health of your body, don’t forget about the trillions of organisms that live inside you: your microbiome, said Dr. John Beard, a professor of productive aging at the Columbia University Mailman School of Public Health.
A healthy gut microbiome, in particular, is associated with healthy aging. It is closely tied to the immune system and helps to control inflammation in the body, a major factor in many age-related diseases.
Research is preliminary, but experts are starting to think that one of the best ways to care for your microbiome is to feed it fermented foods, which add more good microbes to the mix. You could start your day with a bowl of yogurt, or incorporate kimchi, kombucha, kefir or sauerkraut into your diet.
4. Lift weights.
Along with its practical benefits, resistance training causes your muscles to release signaling molecules called myokines, some of which help to tamp down inflammation in the body.
If you’ve spent time around a dumbbell rack, don’t be afraid to challenge yourself with heavier weights, Dr. Gonzalez-Lomas said. But if you’re just starting out, “anything that you do that’s resistance training is going to make a difference.
The goal is to “get to a point where you’re feeling like your muscles are under stress” and starting to fatigue, Dr. Gonzalez-Lomas said.
5. Include a little protein in every meal.
People begin losing muscle mass in their 30s, a process that accelerates in their 60s. Eating enough protein, especially in combination with resistance training, can help to offset that loss.
This doesn’t mean you need to start protein maxxing — the general guideline of 0.8 to 1.2 grams of protein per kilogram of body weight is sufficient, said Dr. Elena Volpi, the director of the Institute for Longevity and Aging Studies at UT Health San Antonio. That translates to 54 to 81 grams of protein per day for a 150-pound adult.
To ensure that you’re getting enough protein every day, and that your body can process it optimally, Dr. Volpi suggested including some protein in every meal.
6. Take the stairs.
Experts talked about the importance of incorporating regular movement into your day-to-day life, not just during dedicated gym sessions.
“I wouldn’t call it exercise, I would call it physical activity,” Dr. Volpi said.
Several studies have found that taking roughly 7,000 steps a day significantly decreases people’s risk of death and diseases associated with aging. You can get in that daily movement in all sorts of ways: by taking the stairs instead of the elevator, walking instead of driving somewhere or, if you do have to drive, parking far away from the entrance. Over time, those extra steps add up and can make a difference for your health.
7. Get the shingles vaccine.
There is growing evidence that the vaccine to prevent shingles also protects against dementia, reducing the risk of cognitive decline by roughly 20 percent. Other vaccines, specifically the influenza, pneumococcal and Tdap vaccines, may also offer some benefit.
Scientists don’t know exactly why this is, but one hypothesis is that by preventing infections, the vaccines protect against major causes of inflammation in the brain and body.
“It’s the easiest thing to be done because, unlike almost all wellness, it’s one and done,” Dr. Emanuel said.
8. Make a list of your parents’ chronic health conditions.
While lifestyle affects people’s risk for age-related diseases, genetics also play a role. Dr. Volpi advised finding out which diseases run in your family, and then talking to your doctor about how best to manage your risk over time. Ask which signs or symptoms you should watch out for, and what you can do about them.
9. Go to bed at the same time every night.
Getting too little sleep is associated with several health conditions, including obesity, diabetes, heart disease and dementia. Perhaps unsurprisingly, it’s also linked to a shorter life span.
The advice to get seven to eight hours of sleep a night is easier said than done. So rather than focusing on a number, the experts recommended doing what you can to set yourself up for success.
Perhaps most important is trying to stick to a consistent bed time. One study from 2024found that sleep regularity — going to bed and waking up at roughly the same time every day — was an even stronger predictor of mortality than sleep duration.

Tune Into Forests From Around The World. Escape, Relax & Preserve
Tree.fm: “People around the world recorded the sounds of their forests, so you can escape into nature, and unwind wherever you are. Take a breath and soak in the forest sounds as they breathe with life and beauty! And while you are here, why not help to grow what keeps us alive? Climate change and governments are destroying our forests. Let’s leave some trees for our grandchildren to climb and make the steps to restore our planet.”
