Stay in the bathtub for an hour and you won't believe what this is doing to you.

If you stay in the bathtub for a few hours (or even minutes, if you don't have much time, it can help you burn unwanted calories, according to one study. Staying in hot water can be compared to the positive effects of a 30 - minute walk. It not only speeds up burning calories but also improves blood sugar levels.

How does this technique work?

A study conducted by a exercise physicist at the University of Louisborough in the United Kingdom revealed that men who showered in hot water or stayed in a bathtub burned 140 calories. It is also proven that hot - water showers can lower the high level of blood sugar more efficiently than exercise, which is especially beneficial for people with diabetes type 2.

The key is time and temperature

The ideal would be to stay in the bathtub for an hour and the water temperature should be in a constant 40 ° C. The experiment was performed only on men, so women can respond differently and may not burn as much calories as men. The results depend on the weight and type of person, and for these reasons, the outcome may be difficult to predict.
