For healthy aging, light exercise or sleep beats being sedentary

Less TV, more physical activity and more sleep — those are the keys to healthy aging according to recent research.

If you want to increase your odds of living a long and healthy life, watch less television and become more physically active, because even a small amount of physical activity can improve overall health, according to an observational study published last month in JAMA Network Open.

While there have been many studies showing that moderate to vigorous physical activity is associated with healthy aging, researchers wanted to know if light physical activity compared with sedentary behaviors also improves healthy aging, and if not, how can people’s time be reallocated.

They found that replacing a sedentary behavior such as watching TV with even low-intensity activity — such as standing or walking around while cooking or washing clothes — increased one’s odds of healthy aging. And at work, replacing some of the time spent sitting with simple movements such as standing or walking around the office can improve health.

“These findings indicate that physical activity need not be high intensity to potentially benefit various aspects of health, which have especially important public health implications as older people tend to have limited physical ability to engage in moderate-to-vigorous physical activity,” Molin Wang, an associate professor in epidemiology at the Harvard T.H. Chan School of Public Health and an author of the study, wrote in an email.

For the purposes of the study, healthy aging was defined as surviving to at least 70 with no major chronic diseases, and no impairment in subjective memory, physical function or mental health. The data, though, suggests the relationship between light activity and healthy aging continues into the 80s and 90s, Wang said.

Replacing TV time with physical activity or sleep

Researchers used responses from a Nurses’ Health Study of 45,176 women that began more than 20 years ago. Respondents were asked questions such as “On average, how many hours per week do you spend standing or walking around at home?” or “On average, how many hours per week did you spend standing or walking around at work or away from home?” Participants had an average age of 59.2 and were free of major chronic diseases when the study began in 1992. They were then tracked for 20 years.

Working in regular exercise, whether it’s a walk in the park or a light workout session at the gym or in a class, is good for healthy aging.

The study incorporated isotemporal substitution modeling to evaluate the potential effect on healthy aging of replacing one hour of one behavior with the equivalent duration of another. They found, for instance, that every two hours spent sitting and watching television was linked to a 12% decrease in the odds of healthy aging. Conversely, every two hours per day of light physical activity at work was linked to a 6% rise in the odds of healthy aging.

Replacing TV time with light physical activity at home increased one’s odds of healthy aging as well. For those who slept seven hours a night or less, replacing television time with sleep was also beneficial for health.

For healthy aging, the activity you choose doesn’t have to be an all-out workout. It could be a light walk or even being active in your house.

“What we found is that if you replace sedentary behaviors with any activities, I mean, even light physical activities, like standing or walking around, or doing household chores, it’s better than just being a couch potato for an extended period of time,” said Frank Hu, professor and chair of the Department of Nutrition at the Harvard T.H. Chan School of Public Health and an author of the study.

And swapping TV time for light physical activity, or sleep for some individuals, at any age would be beneficial, Wang said.

The researchers adjusted for several variables, including age; income; family history of cancer, myocardial infarction and diabetes; baseline hypertension and high cholesterol; menopausal status and postmenopausal hormone use; and diet.

The study findings show an association between sitting and watching television vs. light physical activity, and the odds of healthy aging, and not a causal relationship. The researchers also wrote that because their study population was limited to nurses in the United States, the “findings might not be generalizable to other populations.”

Hu said the isotemporal substitution model they used was important, likening it to the concept of opportunity cost in economic theory or the idea of isocaloric substitutions in food and nutrition. These models acknowledge that people have a finite amount of time in a day or a finite number of calories they are going to consume, so when they choose one thing over another, it comes at a cost of doing something else.

Watching TV and junk food consumption

The problem with watching TV is not just that it’s a sedentary habit. While watching, people tend to eat more junk food and drink more sugary beverages, increasing their caloric consumption, Hu said.

Scott Lear, a professor in health sciences at Simon Fraser University in Vancouver, said that while the findings of the study may not be groundbreaking, researchers made some important distinctions. They made clear that health is also affected by what people are doing when they’re sedentary and where they’re doing it — not just that they’re inactive. There are different health repercussions to sitting at home vs. at work and between sitting and watching TV as opposed to sitting and reading or writing.

“Watching TV has been associated with greater risk for early death, Type 2 diabetes, heart disease, and some cancers, and watching TV is a bit different than just, say, sitting reading a book,” said Lear, who was not involved in the study.

The fact that sleep was included in the study was also novel, Lear said, noting that it’s an underrated health behavior. It may seem like a sedentary behavior, but the brain is very active when we sleep, performing functions that affect our overall health.

He compared the brain to an office, and at the end of the day, all of the day’s happenings — going to the grocery store, having to run to the bus, talking to someone at work — are like files that have been scattered all over the floor and must be picked up and organized by morning. That’s what the brain does when we sleep, he said.

Sleep is also when we remove toxins that build up in the brain throughout the day, and studies have shown a link between an accumulation of this metabolic waste and a person’s risk for dementia later in life, Lear said.

“We talk about physical activity and healthy nutrition. Those tend to be the two heavyweights that we talk about. But sleep is incredibly important,” Lear said.

Adults hop on viral ‘rebounding’ trend to make exercise fun again — ‘I feel like a kid’

Forget boring home workouts, on-demand HITT classes and cold winter runs.

The latest wellness trend bouncing around TikTok involves a workout you might not even realize you’re doing, and that’s the point. It’s called rebounding. This low-impact exercise involves jumping on a mini fitness trampoline — called a rebounder — to get your heart pumping and support lymphatic drainage.

On Amazon, this best-selling model is currently on sale for just $129. It measures in at just 40 inches, making it ideal for small spaces while still offering room for an adult to jump, squat and jog in place. Users swear it gives them a seriously effective full-body workout, and many remark that it’s “so much fun” to use.

Clinical trials also back the benefits: a 12-week rebounding program for overweight women showed significant improvements in body composition as well as a decrease in diastolic blood pressure.

Ready to jump on the rebounding trend, too? You’d better hop on this Amazon deal fast.

Reviewers say it’s completely changed their workouts, with one remarking they “feel like a little kid again.” Others have also noted it’s much easier on their joints than higher-impact exercises.

“It absorbs impact well and allows for a nice, smooth rebound that is gentle on the joints, making it perfect for a low-impact cardio workout,” one person explained. “Whether I’m doing high-intensity intervals or simply bouncing for fun, the movement feels fluid and responsive.

The BCAN model features an upgraded handlebar for added stability. It’s 8mm premium bungee — with a durable woven outer layer and a 350-strand natural latex core — delivers smooth, quiet bounces, so you can enjoy your workout without disturbing others.

Fitness trainer with 18 years of experience shares why exercise is crucial for kids: ‘Not just about health and fitness’

Exercise is often spoken about in the context of physical fitness – stronger muscles, better stamina and improved overall health. But its value, especially for children, extends far beyond the body. Regular physical activity can quietly shape character, teaching lessons about effort, patience, discipline and resilience that mirror how the real world works. From learning to cope with discomfort to understanding that progress takes time, exercise can become a powerful training ground for life itself.

Chennai-based fitness trainer with 18 years of experience, Raj Ganpath – founder of the Slow Burn Method, co-founder and head coach at Quad Fitness, and author of Simple, Not Easy – is shedding light on why exercise is important for kids, with the benefits going beyond health and fitness. In an Instagram video shared on February 27, he explains how the impact of exercise extends far beyond physical wellness, shaping resilience, discipline and long-term character development.

Embracing discomfort

According to Raj, exercise is one of the healthiest ways to help children learn how to sit with discomfort in a safe, structured and sustainable way. Life inevitably brings challenges and unease – something adults understand well – but many children today are shielded from situations that test their resilience.

He explains, “Exercise is a great way to experience this discomfort in a safe and sustainable manner. Lifting weights, holding a plank, doing cardio, repping till it burns, all of these things are opportunities to embrace discomfort, opportunities to put themselves in a place where they’re not comfortable and learn from it, opportunities to practice physical and mental resilience.

Learning hardship

The fitness trainer emphasises that hardship is an inevitable part of life, and meaningful success often requires pushing through moments of difficulty. While most adults recognise this truth through lived experience, children may not always have the same exposure to challenge. Raj believes exercise can bridge that gap.

He elaborates, “It will teach them that they need to do hard things if they want to accomplish something. Getting through a very hard workout, setting a goal and achieving it, completing a task. All of these things are not just random chores. These are incredible opportunities – opportunities to experience hardship and build fortitude.”

Delayed gratification

In today’s fast-paced world, the desire for instant gratification is stronger than ever – and children are growing up at the centre of it. With technology, streaming platforms and 10-minute delivery services, almost everything is available at the tap of a screen. As a result, the ability to wait, persist and work steadily towards a long-term goal can easily take a back seat. Exercise, notes Raj, offers a powerful counterbalance.

He explains, “Everyone wants everything right away today. This is true for us adults too, but it is even more true for our kids because this is the only world they know. A world where everything happens right then and right there, whenever they want it, wherever they want it. Exercise will teach them to wait, to be patient, to trust the process, to fail and still keep going, to work towards something larger that they will get much later. This is a very important character building quality and will serve them well for many, many years to come.”

The fitness trainer concludes, “Exercise is not just about health and fitness. It is a simulation of life itself. A ready-made character building tool available to you to help prepare your kids for life, the raw and real life that they’re going to have to deal with no matter what. So make sure they build the habit and make sure they embrace it.”

What Are “Movement Snacks”? How To Try This Trending Fitness Hack

What Are “Movement Snacks”? How To Try This Trending Fitness Hack

The World Health Organization says the average adult is supposed to get 60 minutes of moderate to vigorous activity five days a week, which sounds somewhat doable until it’s 9 p.m., your kids are finally in bed, and you just want to fall onto the couch and dissociate. But more and more people online are talking about “movement snacks” — little bite-sized amounts of exercise you can do throughout your day to meet your 60-minute goal without having to make special time for one big workout. Because yes, we all want to be our healthiest, but sometimes a HIIT class at the gym is just not in the schedule.

We asked personal trainers and fitness coaches for their favorite movement snacks you can do in the office, around the house, and on busy weekends when everyone’s home.

How much exercise is a person really supposed to get?

While the WHO recommends 60 minutes a day, the CDC is a little more lax, recommending at least 150 minutes of moderate-intensity physical activity a week, or about 30 minutes a day, five days a week. While it may feel like you’re the only one struggling to fit a workout into your daily routine, you’re far from alone. In fact, it’s always been hard for most Americans. So, while movement snacks may be a cute new term we’re all hearing for the first time, fitness pros have been promoting bite-sized exercise forever.

“I work with busy professionals, so I’ve been integrating micro workouts of two to 10 minutes into my clients’ lifestyles for almost 20 years,” says Andrea Marcellus, certified personal trainer and CEO of AND/life.

The most important thing for your health isn’t getting all your daily movement done in one big, perfectly curated workout — it’s about being consistent, Marcellus says. Movement snacks can help you stay consistent because you don’t have to budget a big chunk of time; instead, you can fit something simple into your day when you have three minutes to spare. Hell, you don’t even have to change clothes or go anywhere.

“Most people think movement only counts if it’s a workout. That mindset is what keeps people sedentary. In reality, your body doesn’t care if steps come from a hike, a gym session, or pacing when you’re on a call,” says Lindy Royer, physical therapist and balanced body educator. “This is where you win the game — by stacking movement into things you’re already doing.”

Movement Snacks To Try Throughout Your Day

  • Set an alarm on your phone to chime every hour — that’s what women’s fitness coach Allison Kalsched tells her clients. When it goes off, stand up and do 10 bodyweight squats. Then go back to work. When you get tired of squats, mix in walking lunges, push-ups (it’s fine if they’re modified!), or dead bugs. Throw on 30 seconds of jumping jacks or high knees for bone-building benefits, which is important for women in menopause, she adds.
  • Take a micro walk. “Five minutes or 500 steps is my absolute favorite,” says Dr. Milica McDowell, doctor of physical therapy, author of the forthcoming book Walk, and exercise physiologist at US Physical Therapy. “It changes mood, lowers blood pressure, boosts mental clarity, and can help you get your cumulative steps in.”
  • Dance to your new favorite song with your kids or all by yourself. “Dance party was big with my kids after dinner,” Marcellus says. “It takes four to 10 mins and helps kids burn off dinner energy, while also giving parents a metabolic boost.”
  • Stop and do 60 reps of any full-body exercise, like squats, lunges, or jumping jacks — this usually takes about two minutes, no matter which one you choose, Marcellus says. Or, hold a plank for one to two minutes.
  • Pair walking with habits that already exist to get your steps in, like marching in place while brushing your teeth or doing a lap inside the house while your food is in the microwave. “This means you’re not adding time — you are upgrading your time,” says Royer.
  • Count your housework. Sweeping, mopping, vacuuming, general domestic labor — these things totally contribute to your total exercise time each day, says Royer.
  • If you go up or down the stairs at home, just… do it two or three times. That little extra here and there adds up, according to Royer.

The best advice is to focus not on “how can I move right now?” but “how can I do something that isn’t sitting right now?” Royer says. “The real truth that most people ignore is that sedentary time is the real enemy, not a lack of workouts. Focus on breaking up your sitting time. Build in frequent movement snacks. You’re not looking for perfection, just something more than nothing. You don’t need more time; you actually just need more conscious efforts to move.”
