Most people spend their day sitting. It has recently been revealed that taking long walks can reduce the damage done by sitting down. But this type of activity needs to last for at least one hour.
Surveys done on over one million people have shown that 60 to 75 minutes of moderate-intensity exercise can reverse the damage of sitting for at least eight hours a day.
However, not exercising at all and sitting around all day long is just as dangerous as obesity or smoking, experts have found.
People who also lie in front of the TV for another couple of hours a day after sitting at the office increase their risk of heart disease, diabetes or cancer.
Scientists have long thought that sitting too much isn’t healthy because it weakens the muscles, bones, or the circulatory system. Being inactive is a huge risk factor for muscle damage, heart disease or even cancer.
Physical activity has a host of benefits: it prevents insulin resistance, so it guards against diabetes, keeps the brain fit and strengthens the bones, muscles, and the heart.
Scientists advise getting at least some exercise done, even if it’s only getting out for a walk, going for a jog in the morning or taking the bike to work.
Current guidelines seem a bit outdated because they don’t take into consideration the associated risks of being almost completely inactive.
The new study compiled thirteen older surveys, measuring how much time people spend sitting, how much physical activity they do and how much they spend in front of a screen.
Researchers found that people who did most physical activity – 60 to 75 minutes daily diminished their risk of dying related to sitting for more than eight hours a day.
However, even that pretty intense regime could not counter the effects of a few extra hours of television time.
Conclusions show that the current World Health Organization recommendations, which advise 30 minutes of moderate exercise a day are not enough to completely counter the dangers of sitting down.
When watching TV includes eating unhealthy snacks, the risks skyrocket and it can be worse than sitting down at work.
