A survey of more than 4,500 adults showed that those who counted doing housework as exercise weighed more than those who did other activities for the same amount of time, researchers reported in BMC Public Health. Study leader Marie Murphy, of the University of Ulster, said housework may not provide the intensity needed to meet exercise targets, and she suggested the data indicate people may overestimate the amount of moderate-intensity physical activity they get from housework or eat too much in response to the housework activity performed.
