Walking just 10 minutes a day can lead to a longer life

If almost all of us started walking for an extra 10 minutes a day, overall, we could avert more than 111,000 deaths a year, according to a new movement and mortality study. Published This week in JAMA Internal Medicine, the study used physical activity and mortality data from thousands of American adults to estimate the number of annual deaths that could be prevented if people exercised more. The results show that a little extra physical activity each of us can prevent hundreds of thousands of premature deaths in the years to come.

Now, science has come up with a lot of evidence that how much we exercise affects how long we live. In one say research in 2019 published by the Centers for Disease Control and Prevention, more than 8% of all deaths in the United States are due to “insufficient activity levels”. ONE Studying in the UK since 2015 The same found that men and women who exercised for at least 150 minutes a week – the standard recommendation in the UK, Europe and the US – reduced their risk of premature death by at least 25% compared with those who did not. people exercise less. More significantly, a 2020 examines lifestyle and risk of death of about 44,000 adults in the United States and Europe concluded that the most sedentary men and women in the study, who sat most of the day, were 260% more likely to die early than the most active people studied, who exercised for at least 30 minutes most days.

But much of the previous research was based on people’s often unreliable memories of their exercise and sitting habits. Additionally, many studies that delve into the broader, population-level effects of exercise on longevity tend to use official exercise guidelines as their goal. In those studies, the researchers modeled what would happen if people started exercising for at least 150 minutes per week, an ambitious and perhaps unattainable goal for many. who previously rarely exercised.

In the new study, researchers at the National Cancer Institute and the CDC decided to explore what could happen to mortality if people started moving more, even if they weren’t necessarily. must meet official exercise guidelines. First, however, researchers need to establish a baseline for the number of deaths that might be related to too little travel. So they began to collect data from the ongoing National Health and Nutrition Examination Survey, or NHANES, which periodically asks a representative sample of the population about their lives and health. surname. It also provides some of them with activity tracking tools, to objectively measure how much they move.

The researchers have now collected information from 4,840 participants of different ethnicities, men and women, ranging in age from 40 to 85. All of whom participated in the survey between 2003 and 2006 and Wear an activity tracker for a week. Based on that data, the researchers grouped people by the number of minutes they walked or moved on most days. They also checked people’s names with the national death registry to determine the risk of death for different levels of activity.

Using those results, they set out to generate a series of what-if statistics. Suppose, the researchers asked, that all exercise-capable individuals begin moderate exercise, such as brisk walking, for an extra 10 minutes a day, in addition to their current level of exercise. how much or little? How many deaths could not have happened?

The researchers made adjustments to calculate statistics for people who were too weak or unable to walk or move around easily. They also consider age, education, smoking status, diet, body mass index and other health factors in their calculations.

The researchers then ran the same statistical scenario with everyone exercising for an extra 20 minutes a day, and finally, an extra 30 minutes a day and examined mortality outcomes.

They found that quite a few people would have lived longer in any of these circumstances. According to the model, if every adult were able to walk briskly or exercise for an extra 10 minutes a day, 111,174 annual deaths nationwide could be avoided – or about 7% of all deaths in the United States. a typical year – can be avoided.

When they doubled the amount of fantasy exercise to 20 minutes a day, the number of deaths potentially prevented rose to 209,459. Tripled exercise to 30 minutes a day averted 272,297 deaths, or nearly 17% of the typical annual total. (Data collected before the pandemic, has skewed the death count.)

Those numbers may seem abstract, but in reality, the hundreds of thousands of foretold deaths can be deeply personal. Pedro Saint-Maurice, an epidemiologist at the National Cancer Institute who led the new study, said they could mean avoiding the premature death of a spouse, parent, friend, older child, co-worker industry or of course us. “There is a message in this data for public health authorities” about the importance of promoting physical activity to reduce premature deaths, he said. And the message applies equally to each of us.

So get up and go for a walk or do some extra 10 minutes of moderate physical activity today. Invite your friends, colleagues and elderly parents to do the same. “In this context, a little extra physical activity can have a huge impact,” says Dr. Saint-Maurice.
