A study of Good housekeeping institute found that people doing two hours of “intense” household chores actually burned more than 600 calories.
The GHI found window cleaning to be the most taxing task, with participants burning an average of 115 calories in 20 minutes. Scrubbing the bathroom top to bottom burned an average of 100 calories, while dusting for 40 minutes (how big is that house?) burned nearly 200 calories in total.
To put that into perspective, 600 calories is almost double the calories lost in a 5k run, and the equivalent of an hour of training in the park, 40 minutes of squash or 100 minutes of cricket. .
