Sitting for hours on end is linked to nine more cancers than we thought, according to the cancer expert who is helping to re-write the exercise guidelines. Charles E Matthews, an epidemiologist at the National Cancer Institute, warns we need more physical activity than we thought – but more importantly, we need to sit less.
Just one hour of TV a day puts even the most active of us at a higher risk of not just breast and colon cancer – which we already knew – but also nine other cancers including lung and head or neck.
“Watching TV is the major competitor to going out and being more active,” he told the American Association for the Advancement of Science conference in Austin, Texas. “This is where moderate activity like a brisk walk or things around the house come in. Anything that is not sitting is good.”
Now we’re not suggesting standing and watching the TV at home but if you’ve been non-sedentary at work using a standing desk you can afford some rest time watching your favourite TV programme for an hour or so!
