Take a stand for a longer life.
The researchers say that even a few extra minutes each day on the couch can extend your life by several years.
"If you have a job or lifestyle that requires a lot of time sitting, you can reduce your risk of premature death by moving more often, for as long as you want and within your means." Intensity or choose less intense activities, such as walking, "said lead author Keith Diaz.
He is an Assistant Professor of Behavioral Medicine at Columbia University in New York.
The new study included nearly 8,000 American adults aged 45 and over. As part of a research conducted between 2009 and 2013, each of them was wearing a physical activity monitor for at least four days. Investigators then tracked deaths among participants until 2017.
Findings: People who replaced just 30 minutes of sitting per day with low-intensity physical activity reduced their risk of premature death by 17%, according to the study published online Jan. 14 American Journal of Epidemiology.
More intense exercises yielded even greater benefits, said the researchers. For example, exchanging half an hour a day while sitting to exercise from moderate to vigorous reduces the risk of premature death by 35%.
And even a minute or two of extra physical activity has been beneficial, showed the results.
"Any physical activity, whatever the intensity of it, is good for your health," Diaz said in a press release published by a university.
His team cited a recent study that found that one in four American adults sits for more than eight hours a day.
Inactivity a killer
Two heart health experts believe that the level of inactivity can be a mortality factor.
"Exercise, regardless of the risk level of cardiovascular disease, not only improves lifespan, but also decreases the risk of heart attack and stroke," said Dr. Satjit Bhusri, cardiologist at Lenox Hill Hospital in New York.
And Dr. Guy Mintz, a heart disease specialist, said Americans can change their lazy ways in many ways. He leads cardiovascular health at Sandra Atlas Bbad Heart Hospital of Northwell Health in Manhbadet, NY.
The American Heart Association currently recommends "a moderate aerobic activity 150 minutes a week or a vigorous aerobic activity 75 minutes a week," Mintz said.
"Some American companies, like Google, are taking note of the importance of exercise and the adverse consequences of a sedentary existence, including an increase in obesity, diabetes and heart disease. ", added Mintz. "Employees are encouraged to get up from their desk and do some exercise – that it's all about stretching, ping-pong, walking, puppets, mats running or stationary bicycles. "
He believes that other companies could follow this example.
"Employers with tight work schedules need to schedule mandatory staff time every day so that they can exercise and make it fun," said Mintz. "The benefits to the employer and the employees are beneficial, the companies are also earning with increased productivity, fewer sick days, lower health costs and improved morale."
For his part, Diaz said that future research "would examine the risk of specific cardiovascular consequences, such as heart attacks, heart failure and cardiovascular-related deaths, badociated with physical activity versus sedentary behavior." "
