- Most Americans spend at least two hours a day watching television or videos, and a new study suggests they're becoming more sedentary as they devote more remaining free time to sitting in front of computers.
"As our daily life demands less physical activity, we accumulate sedentary time from sitting at school/work, motorized transport, watching TV, computer use and so on," all of which may be driving recent increases in total sitting time, Yang said by email. The study wasn't a controlled experiment designed to prove whether or how sitting time might directly impact health outcomes.
"It is important to remember that our society has positively viewed most labor saving devices like microwave ovens, washing machines and fast food restaurants as ways to save time that can be devoted to leisure time," Mainous said by email.
