An article written by Harvard Heart Editor under the Harvard Medical School has suggested and validated that sitting too much is definitely harmful to our overall health, even those who spent up to an hour of day exercising are still at risks, a research conducted by Canadian research across 47 studies reported the findings. The researchers
adjusted for other types of activity people did, from leisure-time activities to vigorous exercise, the results of the findings reported that "over the course of these studies, people who sat for prolonged periods of time had a higher risk of dying from all causes — even those who exercised regularly. The negative effects were even more pronounced in people who did little or no exercise."
Though it is still not clear how sitting can exactly contribute to poor health. But some research suggested there are some negative effects on sugar and fat metabolism, which ultimately will lead to the risks of respective illness like heart disease and diabetes suggested by Dr. I-Min Lee, a professor of medicine at Harvard Medical School.
Encourage your friends to move around with you more, preferably move for 2-3 minutes every 30 mins of sitting. We actually burn 30% more standing than sitting suggested by Dr. Lee at Harvard school. And gradually over time, it helps with weight control. Fear of death is not enough to motivate people to make a change to start standing more, but probably weight loss will be a good starting point!
“The key is to make these things habits that you do without thinking about, like brushing your teeth,” says Dr. Lee.
