As we get older, unfortunately our chances of having a stroke rise. While there’s obviously no way to turn back the clock on our age, fortunately there are ways to lower our risk of a stroke and that includes staying physically active. Take walks, ride a bike, play a favorite sport. According to our current exercise guidelines for American adults, the goal is to get in at least two and a half hours each week of moderate-intensity physical activity as well as two days of muscle-strengthening activity [1].

But a new study, published in the journal JAMA Network Open, shows that reducing the chances of a stroke as we get older doesn’t necessarily require heavy aerobic exercise or a sweat suit [2]. For those who are less mobile or less interested in getting out to exercise, the researchers discovered that just spending time doing light-intensity physical activity—such as tending to household chores—“significantly” protects against stroke.

The study also found you don’t have to dedicate whole afternoons to tidying up around the house to protect your health. It helps to just get up out of your chair for five or 10 minutes at a time throughout the day to straighten up a room, sweep the floor, fold the laundry, step outside to water the garden, or just take a leisurely stroll.

That may sound simple, but consider that the average American adult now spends on average six and a half hours per day just sitting [3]. That comes to nearly two days per week on average, much to the detriment of our health and wellbeing. Indeed, the study found that middle-aged and older people who were sedentary for 13 hours or more hours per day had a 44 percent increased risk of stroke.

These latest findings come from Steven Hooker, San Diego State University, CA, and his colleagues on the NIH-supported Reasons for Geographic and Racial Differences in Stroke (REGARDS) study. Launched in 2003, REGARDS continues to follow over time more than 30,000 Black and white participants aged 45 and older.

Hooker and colleagues wanted to know more about the amount and intensity of exercise required to prevent a stroke. Interestingly, the existing data were relatively weak, in part because prior studies looking at the associations between physical activity and stroke risk relied on self-reported data, which don’t allow for precise measures. What’s more, the relationship between time spent sitting and stroke risk also remained unknown.

To get answers, Hooker and team focused on 7,607 adults enrolled in the REGARDS study. Rather than relying on self-reported physical activity data, team members asked participants to wear a hip-mounted accelerometer—a device that records how fast people move—during waking hours for seven days between May 2009 and January 2013.

The average age of participants was 63. Men and women were represented about equally in the study, while about 70 percent of participants were white and 30 percent were Black.

Over the more than seven years of the study, 286 participants suffered a stroke. The researchers then analyzed all the accelerometer data, including the amount and intensity of their physical activity over the course of a normal week. They then related those data to their risk of having a stroke over the course of the study.

The researchers found, as anticipated, that adults who spent the most time doing moderate-to-vigorous intensity physical activity were less likely to have a stroke than those who spent the least time physically active. But those who spent the most time sitting also were at greater stroke risk, whether they got their weekly exercise in or not.

Those who regularly sat still for longer periods—17 minutes or more at a time—had a 54 percent increase in stroke risk compared to those who more often sat still for less than eight minutes. After adjusting for the time participants spent sitting, those who more often had shorter periods of moderate-to-vigorous activity—less than 10 minutes at a time—still had significantly lower stroke risk. But, once the amount of time spent sitting was taken into account, longer periods of more vigorous activity didn’t make a difference.

While high blood pressure, diabetes, and myriad other factors also contribute to a person’s cumulative risk of stroke, the highlighted paper does bring some good actionable news. For each hour spent doing light-intensity physical activity instead of sitting, a person can reduce his or her stroke risk.

The bad news, of course, is that each extra hour spent sitting per day comes with an increased risk for stroke. This bad news shouldn’t be taken lightly. In the U.S., almost 800,000 people have a stroke each year. That’s one person every 40 seconds with, on average, one death every four minutes. Globally, stroke is the second most common cause of death and third most common cause of disability in people, killing more than 6.5 million each year.

If you’re already meeting the current exercise guidelines for adults, keep up the good work. If not, this paper shows you can still do something to lower your stroke risk. Make a habit throughout the day of getting up out of your chair for a mere five or 10 minutes to straighten up a room, sweep the floor, fold the laundry, step outside to water the garden, or take a leisurely stroll. It could make a big difference to your health as you age.

    I reached my 88th birthday June 8th. No relatives ever reached this age or past 70’s. I am intellectually capable, retired from several scientific careers. I never rode a bike, too poor to ever have one. Rarely suffered physical challenges, i.e., small breast cancer, cataracts, cornea transplants due to Fuchs Dystrophy in 2003,2004. Excellent vision then with corrective glasses subsequent after about 12 years post surgery. I developed mild type 2 about 10 years ago. I have had carpal tunnel syndrome occasionally due to extreme use of calculator for work. I also have a torn rotator cuff but refused surgery years ago and have made accommodations by lowering groceries, appliances, clothing, etc., and have had several injections over the years which I discontinued in the event I might need other correctives which would require a 3-month abstinence from those.
    I am about 5’3″, weigh about 130, Hip pain, refused surgery, pain diminished after several years. Interesting article in BMJ. Other minor, back fall mistake, no injury,Years ago I noticed an uncomfortable sensation as I started to back away from kitchen counter and in all these years never backed. Carelessly I backed away from dusk and had an extreme violent backward fall. No injury, though hospitalized. Left hand possible hand block, I self-diagnosed as minor brain stroke which has left fingers less agile and slightly painful. Incidentally, cardiac conditions killed all maternal family on maternal side, carotic stroke killed father who was heavy smoker, age 68, while his identical twin stropped smoked years before and lived to to 86, also had different diet due to poverty.
    I have done a genealogical study along in cooperation with a distant relative. I have decreased excessive activities, no more ladder climbing nor stairs, elevator is fine. I still drive but since covid have not gone to indoor activities. Groceries occasionally, deliveries by call, If you are interested, I would participate, as my age seems to harbor unusual abilities.

  • Dorothy Zelder says:

    I am 90 years old (in 2 weeks),in excellent health and many people (and Dr.s) don’t get ‘why.’
    P.S. I move and I think and I don’t think about age. I do what I want and I’m ME…..

  • Zuccheri Gianni says:

    What is highlighted in this article is very important, adequate physical activity is a fundamental pillar for health, at any age. A reflection arises: it would be appropriate to start considering that combating the occurrence of stroke not late in life, when perhaps it is late!

    The metabolic alterations (e.g. diabetes, dyslipidemia, arterial hypertension, etc.) that lead to vascular obstructions, prepare their development in young age. While everyone knows the harm of smoking, we don’t always remember the need for the right amount of food: excess salt, too many sweets and a sedentary lifestyle always produce harmful effects.

    As rightly pointed out for the adult person, the movement in order not to sit constantly, should also be contemplated in school activity. It would be a good idea to teach and perform movements frequently when sitting for a long time. In this way, incorrect postures are avoided and the circulation of the lower limbs is helped.

  • Fahmida pathan says:

    Physical activity is a must not only for stroke, but also for happy and healthy life. Don’t waste your time by sitting, just move.

  • B says:

    It proves a correlation but not a causation

  • Jen says:

    Good advice, but the study cannot necessarily conclude that sitting erases the gains of exercise. As B said there’s a correlation but not necessarily causation. There are numerous reasons why a person would be excessively sedentary and where moderate exercise might not remove health risks. Plus, we may not quite understand the full effects and mechanisms of exercise on health.

  • Flora C. Rowse says:

    I am 86 years old and very active. I keep house and tend the garden. I even shovel a little snow in my patio when necessary. I walk 1 and 1/2 to 2 miles every day except when there is snow and ice. I swim 1,000 to 1,200 yards twice a week and train for Senior Olympics in 100 yards free style, back stroke and breast. It’s fun and wonderful exercise!! I am in two book clubs and play Canasta each week. I live in an active adult community and feel that I am living the best life. I feel like I did when I was in my 40’s, Age is only a number!!

  • LINDA L MYERS says:

    My Mother lived to 107 never took a maintenance prescription medicene.She was gardening and canning until age 95. Walked daily inside and out. She lived alone at a senior apartment until 4 months before she came to spend winter with me. One morning she told me she was staying in bed and passed 6 hours later. I am 83 and do not take any RX.


  • Shirley Burt says:

    I am 88 yrs. and lead an active life, waiting for it to get light enough outside to take my usual 2mile walk. If you don’use it, you will lose it!
