介绍:
Potential Health Dangers of Sitting Too Much
AZUZ: Is it true that the more time you spend sitting, the less time you`ll spend living?
A new study published this week in the "Annals of Internal Medicine" suggests long periods of sitting down are a risk factor for early death, even if you exercise. Of course, many Americans aren`t doing enough of that either. More than 80 percent of adults are estimated to fall short of
strength training twice a week and getting at least two and a half hours of aerobic activity weekly.
But if the sitting is making things worse, there is a silver lining. The study found that people who take a break, to move around every 30 minutes have the lowest risk of early death. It`s a wake up call for all of us to get on our feet.
SUBTITLE: Sitting can kill you.
DR. SANJAY GUPTA, CNN CHIEF MEDICAL CORRESPONDENT: I have sat more than just about anybody else. In fact, I was calculating this the other day, just based on my travel alone, I have traveled enough to have circumnavigated the Earth a hundred times. And I know that sitting can be really bad for you.
We humans did not evolve to be sitting creatures. We evolve to be naturally moving all day long. In fact, some people have called sitting the new smoking.
One of the big concern is something known as DVT, deep venous thrombosis. Think of these clots that are forming in the deep veins of your legs, the blood is just not moving very well. There`s where the clots start to form. That can be painful to your leg.
Your best bet if you`re forced to sit is to try and get the blood moving. Simply moving some exercise of your legs, spinning your feet around to actually get the blood flowing. Make sure to drink plenty of water. And if you can, get up and walk around.
That`s your best bet to live to a hundred.
