Energy balance

Activation of brown adipose tissue (BAT) through cold exposure increases whole-body energy expenditure and improves glucose and lipid metabolism in humans.

If you have detectable brown fat, exposing yourself to cool temperatures (around 17°C or 63°F) for about 2 hours daily can help increase your energy expenditure and reduce body fat. This works by activating your brown fat to burn calories as heat.

GoodSupportsHIGH confidence
In summary, BAT activation through cold exposure was able to increase energy expenditure and have beneficial effects on glucose metabolism supporting its role in treating obesity and related metabolic disorders in humans.
