Canadians are being encouraged to stay at home in many parts of the country to help prevent the spread of COVID-19. But it turns out staying home can have its own hazards, and they creep up a lot faster than you might think.

Reduced physical activity — the kind that happens when people spend their time indoors and don’t include exercise in their daily routine — is bad for your health. It’s not just losing muscle mass and gaining body fat, either: possible effects range from insulin resistance to declining mental health. And it happens alarmingly fast. It only takes a couple of weeks for inactivity to start taking a toll on the body.

Today in The Conversation Canada, McMaster University physiologist James McKendry highlights the dangers of spending too much time on the sofa, and discusses options for being physically active to stay strong and healthy through the long winter ahead.

Budget cuts and outsourcing content has affected the amount and quality of science journalism. Scientists should learn to communicate their own findings directly and clearly to the public.
