The World Health Organization says people need to get more active, warning that up to five million deaths worldwide could be avoided each year if people were. That’s despite the coronavirus pandemic.

The U.N. health agency, launching updated guidelines on sedentary behaviour Thursday, is pointing to figures that one in four adults don’t get enough physical activity – a situation complicated by the COVID-19 crisis that has shut many people indoors.

The agency recommends at least two and a half hours of “moderate to vigorous aerobic activity” for adults per week, and an hour per day for kids and teens.

A lack of physical activity leads to extra health care costs of US $54 billion per year, plus another US$14 billion in lost productivity, the Geneva-based WHO said.
