Baths vs #Exercise, a Study in Calories
https://www.theAtlantic.com/health/archive/2017/04/baths-and-calories/522756 In 1hr, burn 60 in a hot bath vs ~550 on a bike ride. Laziness has benefits!
The researchers set out to see how exposure to heat can alter the molecules in our bodies. There were only 14 people (all men) in the study. They took hour-long baths at 104-degrees Fahrenheit and did burn calories, which were also measured, since energy is required to keep our cores around 98.6-degrees. But the men only burned an average of about 61 calories more than if they had been sitting at room temperature. When they exercised on a bike for the same amount of time, they burned between 515 and 597 calories.
