第一章 Sitting Around Is Bad For Your Heart
動一動，心髒更健康
A new study from the Journal of Medicine and Science in Sport and Exercise says if your bottom spends too much time parked in a chair, your heart pays a heavy price. It finds the more hours of what’s called“sitting time”over the course of your day, the more time for blockages to clog up your arteries. Let’s
take a typical eight-hour shift. let’s say you’re sitting less than two hours, or a quarter of your day. Well in that case, you’re probably OK. But when half of your day is spent taking a load off your risk of heart disease goes up about twelve percent. Spend six hours of that frozen in a chair, and the risk zooms up by more than a third. And if your eight hours is basically eight hours of desk work. It Jumps more than fifty percent higher. So how can you st and up and fight the war against“sitting time”. Well, number one, take the stairs, not the elevator. Take walking breaks, not coffee breaks. let your legs do the walking. Don’t e-mail, go speak to a co-worker in person. And if you need to use the restroom, choose the one that’s farthest away. And finally, take a walk rather than eating lunch at your desk.
