How sedentary behaviour increases your risk of cancer
Our recommendation @(Model.HeadingTag)>
Sit less. Plan your day to take frequent, short breaks from sitting. Being active decreases your risk of cancer, but sedentary behaviour is an independent risk factor. Even if you exercise 30 minutes or more every day, if you’re sedentary for most of your days, you are still at an increased risk for cancer.
It’s shocking how many hours a day Canadians sit
Yikes! It's true – each day, Canadian adults spend almost 10 hours, approximately 60%, of their waking time being sedentary.
Being sedentary refers to activities that need very little physical movement and don't use much energy, such as sitting or lying down for long periods of time. Sedentary behaviour is different than not getting enough exercise.
We're spending more and more time on screens – TVs, smartphones, tablets and computers. And when we're texting, watching videos, playing online games, hanging out on the Internet or sharing on social media, we're usually sitting.
We also spend more and more time in our cars and on public transit. And with the rise in technology, many of us spend our days sitting at work as well.
Researchers recognize sedentary behaviour as a health risk since it can lead to weight gain. Obesity is a risk factor for at least 11 types of cancer.
