A recent study found that showering alternating between cold and hot water may provide health benefits to the body, the most important of which is burning fat.
And the Danish study shows that routinely swimming or immersing in cold water with hot sauna sessions may affect how brown fat is burned.
Brown fat, or brown adipose tissue, is a special type of body fat that turns on when you cool down. Brown fat produces heat to help maintain body temperature in cold weather.
The study explains: Swimmers burn more calories than people in a sauna only during cooling, possibly due in part to increased heat production.
