Does Working Out Undo The Health Risks From Sitting? New Research Reveals The Truth
Sitting for long periods has never been hailed as healthy, yet many people have relied on their workouts to counter the negative effects of being on their tush all day. However, recent research challenges this common assumption that regular workouts are the perfect antidote.
The study, which was recently published in the Journal of the American College of Cardiology, found that doing the recommended amount of moderate-to-vigorous exercise during the week probably isn't enough to counteract all of the cardiovascular risks of being sedentary for prolonged periods. Of course, there's only so much you can do if you happen to have a desk job, making this health conundrum tricky to navigate.
Here's what the study uncovered, plus what cardiologists recommend doing if you have to sit for longer periods of time.
Meet the experts: Rigved Tadwalkar, MD, is a consultative cardiologist and medical director of the Cardiac Rehabilitation Center at Providence Saint John's Health Center in Santa Monica, California. Christopher Berg, MD, is a cardiologist at MemorialCare Heart and Vascular Institute at Orange Coast Medical Center in Fountain Valley, California. Ragavendra Baliga, MBBS, is a cardiologist and professor of internal medicine at The Ohio State University Wexner Medical Center.
For the study, researchers analyzed one week of activity tracker data collected from more than 89,500 people who participated in the U.K. Biobank, a longitudinal health study to assess how many hours people sat during the day and how much moderate to vigorous physical activity they achieved, and followed up across a decade.
The researchers then broke down the data to look at the associations between how much time people spent sitting during the week, along with their future risk of developing atrial fibrillation (an irregular heartbeat), heart attacks, heart failure, and death from cardiovascular causes.
After crunching the data, the researchers discovered that people who were sedentary had a higher risk of developing all of the cardiovascular issues just mentioned. But those who sat for more than 10.6 hours a day (not including when they were lying down asleep) had up to a 60 percent higher risk of developing heart failure or dying from a cardiovascular cause.
The research also determined that the risk of developing atrial fibrillation and heart attacks mostly was mitigated if the excessive sitters got the recommended 150 minutes (or more) moderate-to-vigorous physical activity per week. But meeting the exercise requirement only partially offset the risk of heart failure and dying from a cardiovascular cause.
As a result, squeezing more standing time and movement into your day beyond your exercise window to break up prolonged periods of sitting seems to be vital. 'Optimizing sedentary behavior appears to be important even among physically active individuals,' the researchers wrote.
This is hardly the first study to link sitting for hours and hours a day to serious health issues. Spending long periods of time sitting has been linked to a higher risk of developing obesity, high blood pressure, type 2 diabetes, and certain types of cancer, in a number of studies. And the American Heart Association (AHA) recommends people spend less time sitting in their general guidelines to support heart health.
Here's why the heart gets the short end of the stick with too much couch time: 'Lack of movement slows circulation, weakens the heart muscle, and contributes to weight gain, along with high blood pressure, and insulin resistance,' says Rigved Tadwalkar, MD, a consultative cardiologist and medical director of the Cardiac Rehabilitation Center at Providence Saint John's Health Center. Sitting for longer periods of time may also raise the risk of bodily inflammation, which is linked to a slew of serious diseases.
And, yes, even super active individuals are in the danger zone. 'Even those who exercise can be at risk if they are sedentary for most of the day,' Dr. Tadwalkar adds.
Simply put: Watch the clock and sit for as little time per day as you can. "Limiting sedentary time to under 10.6 hours per day may be a practical baseline for improving heart health," says Ragavendra Baliga, MBBS, a cardiologist and professor of internal medicine at The Ohio State University Wexner Medical Center.
But you're not screwed if you have a desk job. Doctors say it's important to be aware of how much you're moving throughout the day. If there's room for improvement, they always recommend being more active when and where you can.
'Getting active is one of the most important things people with heart disease or at risk of heart disease—which is everyone—can do to improve their heart health,' says Christopher Berg, MD, a cardiologist at MemorialCare Heart and Vascular Institute at Orange Coast Medical Center.
He recommends having a regular exercise plan in place, and doing whatever you can to fit in at least 150 minutes of moderate-to-vigorous physical activity a week. If you're not already working out consistently, Dr. Berg suggests committing to a smaller goal and working your way up. (Head here for sound advice on setting realistic and attainable workout goals.)
To supplement your regular workout routine, it's also essential to do what you can to squeeze in more micro movement pockets through your day, says Dr. Berg.
Take the stairs whenever you can.
Take a lap around your office or home when you find a moment during your workday.
Take the long way to and from the bathroom.
Use a standing desk.
Park farther away from store entrances to get in more steps.
Stand up and walk around when you need to be on a call.
Sneak little exercises into your day, like doing squats or jumping jacks.
Find small pockets of time to stand as much as possible before and after work, like having breakfast and dinner at a tall countertop.
Consider getting a fitness tracker to keep tabs on your step count and offer alerts and nudges to remind you to move.
'These are all small, easy actions that one can do to improve health,' Dr. Berg says.
Of course, if you have a family history of heart disease or are especially worried about your risk, it's a good idea to check in with a medical professional. They can give you an evaluation and suggest personalized next steps from there.

This Type Of Work May Lower Heart Attack Risk For Women, Says New Study
A new study suggests that being self-employed can have an impact on your heart health. Specifically, it can help improve cardiovascular risk factors like obesity, sleep, and activity. Experts have a few theories why this might be, including lower stress and greater freedom to follow a healthy lifestyle. We all know there are a lot of factors that can influence your heart health, from what you eat to your family history, but new research suggests that your work environment might actually have a big influence how likely women are to develop cardiovascular disease. The findings, which are published in the journal BMC Public Health, suggest that being self-employed can have a noticeable influence on factors that lead to your risk of heart attack, stroke, and more. Right now, the study only establishes an association—so don't quit your day job and strike out on your own based purely on these findings. But they do raise a lot of questions about how your workplace can impact your heart and overall health. Here's what the research suggests, plus what doctors want you to keep in mind about the fascinating findings. Meet the experts: Jennifer Wong, MD, cardiologist and medical director of Non-Invasive Cardiology at MemorialCare Heart and Vascular Institute at Orange Coast Medical Center in Fountain Valley, CA; Kimberly Narain, MD, MPH, PhD, lead study author assistant professor-in-residence of medicine in the division of general internal medicine and health services research at the David Geffen School of Medicine at UCLA. Yanting Wang, MD, an associate professor at Rutgers Robert Wood Johnson Medical School and director or the Women's Heart Program and Cardio-Obstetrics Program at Robert Wood Johnson University Hospital. For the study, researchers analyzed data from 19,400 working adults who participated in the National Health and Nutrition Examination Survey (NHANES). The researchers crunched the data to look at the link between being self-employed and having cardiovascular risk factors like high cholesterol, high blood pressure, glucose intolerance, obesity, poor diet, physical inactivity, smoking, binge drinking, sub-optimal sleep duration, and poor mental health. Researchers discovered lower rates of certain cardiovascular risk factors between people who were self-employed and those who were salaried. White women who were self-employed had a 7.4 percent lower risk of obesity, 7 percent lower risk of being physically inactive, and 9.4 percent drop in having poor sleep. The change in risk was slightly different for self-employed women of color. These women had a 6.7 percent lower risk of having a poor diet, 7.3 percent lower risk of being physically inactive, and 8.1 percent lower risk of getting poor sleep. Self-employed white men also saw a drop in certain factors, although it wasn't as noticeable. (Minority men didn't see the same benefits.) The study didn't explore this exact question beyond just finding a link, but there are a few theories, according to Kimberly Narain, MD, MPH, PhD, lead study author assistant professor-in-residence of medicine in the division of general internal medicine and health services research at the David Geffen School of Medicine at UCLA. One is that women who are self-employed may be able to dictate their work schedule more and have less stress as a result, she says. Self-employed women with more free time may possibly have 'less perceived stress compared to women with less autonomy,' says Jennifer Wong, MD, cardiologist and medical director of Non-Invasive Cardiology at MemorialCare Heart and Vascular Institute at Orange Coast Medical Center in Fountain Valley, CA. (Chronic stress is a risk factor for cardiovascular disease on its own, but it can also raise the risk of developing other factors that contribute to the condition, like obesity or trouble sleeping.) Women also tend to be caregivers and as such, have more responsibilities at home, Dr. Narain points out. 'When you're trying to combine that high level of demand and employment that doesn't have autonomy and flexibility, it can be stressful,' she says. 'It can potentially manifest in higher levels of blood pressure and less sleep.' Unfortunately, both of those raise your risk for cardiovascular disease. Women who are self-employed may have greater freedom to take on healthy lifestyle habits, like being more physically active and making medical appointments to stay on top of their health, says Yanting Wang, MD, an associate professor at Rutgers Robert Wood Johnson Medical School and director or the Women's Heart Program and Cardio-Obstetrics Program at Robert Wood Johnson University Hospital. Finally, Dr. Narain says that self-employed women may not have to deal with micro-aggressions that can happen in the workplace—and that can also lower stress. Dr. Narain says the findings suggest that your work environment can have an impact on your cardiovascular health. 'We really need to be thinking about the meaning people get from their work and what that may mean for their health outcomes,' she says. But Dr. Wong says the study also stresses the importance of taking care of your health, no matter what your job is. 'In any job, women should try to take the time to optimize their cardiovascular health focusing on a heart healthy diet, exercise, and adequate sleep,' she says.

Who needs more exercise: Women or men?
Exercising regularly is known to lower the risk of death, especially from heart problems. But scientists have discovered that that reduction in risk may differ between the sexes, with some people reaping greater benefits in less workout time. So, who has to exercise more to reduce their risk of death: Women or men? It turns out that women may reap these survival benefits more easily than men do. That's according to a large study published in 2024 in the Journal of the American College of Cardiology , which included data from more than 412,000 American adults ages 27 to 61, 55% of whom were female. You may like 'The beauty of this study is learning that women can get more out of each minute of moderate to vigorous activity than men do,' study co-lead author Dr. Martha Gulati , director of preventive cardiology in the Smidt Heart Institute at Cedars-Sinai, said in a statement . 'It's an incentivizing notion that we hope women will take to heart.' The researchers collected participants' physical activity data via the National Health Interview Survey (NHIS), the largest and longest-running health survey in the U.S. The study looked at data collected between 1997 and 2017. Related: 11 minutes of moderate exercise a day cuts early death risk by 20%, huge analysis suggests The survey itself included questions about the types of exercises people performed and at what frequencies, durations and intensities. It also included participants' socioeconomic and demographic characteristics and medical conditions. The study excluded people who had certain health conditions at the start of the study time frame, such as coronary heart disease or cancer.

The researchers also looked through the National Death Index — a national database of death records — for deaths from any cause, as well as cardiovascular-related deaths. The data from survey participants is linked to this death-record data , so the researchers could then connect the data from their NHIS participants to the mortality data through the end of 2019. Overall, 39,935 participants died in the study timeframe, including 11,670 cardiovascular-related deaths, such as those from heart disease, heart attacks and strokes. About 32% of the women and 43% of the men surveyed said they engaged in regular aerobic exercise , exercising for at least 150 minutes per week. Compared to inactive individuals of the same sex, women who exercised regularly had up to a 24% lower risk of death from any cause. For men who exercised regularly, however, the reduction in mortality risk reached only 15%. Women also gained these survival benefits much more quickly than men did, the study found. In men, the highest reduction in death risk was seen at about 300 minutes of moderate-to-vigorous physical activity (MVPA) per week. That came with an 18% reduction in all-cause mortality. Women saw an equal benefit in less than half that time, at about 140 minutes of MVPA a week. Women who trained more than that each week saw a greater benefit until they also peaked at around 300 minutes of weekly MVPA. That trend held true across all durations of exercise, the researchers found, with women consistently seeing 'proportionately greater benefits' for any amount of exercise than men did. About 20% of women and 28% of men said they engaged in two or more sessions of strength training, such as lifting weights, each week. Overall, though, women reported an average of about 0.85 sessions per week, while men averaged 1.25 sessions per week. On average, the women who strength-trained at least twice a week had a 19% lower mortality risk than women who trained less often or not at all. Men, on average, saw a 11% lower risk compared with inactive men. These benefits were even greater when it came to cardiovascular health specifically. Related: Why is it harder for some people to build muscle than others? Compared with inactive individuals, women who performed aerobic physical activity had a 36% lower cardiovascular mortality risk, while for active men, this risk reduction was about 14%. Muscle strengthening produced similar outcomes, with a cardiovascular risk reduction of 30% for women and 11% for men, compared to baseline. 'What surprised us the most was the fact that women who do muscle strengthening had a reduction in their cardiovascular mortality by 30%,' Gulati told NPR . 'We don't have many things that reduce mortality in that way,' she added. The study did have some limitations, including that people's exercise data was self-reported, so it relied on the participants accurately reporting their activity study also tracked only leisure-time exercise, meaning it didn't count exercise completed during household tasks or as part of a job, which may have also contributed to the results. In addition, the study didn't account for potentially unassessed health issues in some participants, or changes in people's exercise trends over time. That said, the results echo similar findings from a 2011 meta-analysis published in the journal Circulation . This review of 33 studies concluded that there was a stronger link between exercise and lower death risk in women than men. The researchers behind the 2024 study hope their findings could help motivate more women to exercise, whether through traditional ' cardio ' or muscle strengthening regimes including bodyweight exercises or lifting weights. 'I am hopeful that this pioneering research will motivate women who are not currently engaged in regular physical activity to understand that they are in a position to gain tremendous benefit for each increment of regular exercise they are able to invest in their longer-term health,' Dr. Christine Albert , chair of the Department of Cardiology in the Smidt Heart Institute who was not involved in the study, said in the statement.
