Warm bath before meal increases growth hormone levels
Growth hormone repairs joints, skin and other connective tissues. Some endocrinologists suspect that intensive exercise can slow down aging because exercise increases the production of growth hormone. If this is true, exposure to heat may have the same rejuvenating effect as exercise.
Study
British researchers at Loughborough University gave 10 healthy young men 75 grams of glucose dissolved in water on 2 different occasions. On one occasion, the subjects had been in the bath for an hour before administering the glucose. The temperature of the water was 39 degrees [hot water immersion]. The other time the men had been in a room [control].
Results
After the glucose intake, the researchers monitored the subjects' blood. Exposure to the warm water seemed to slow down the rise in insulin levels and increased glucose levels.
The effects of the warm water on the glucose and insulin balance were not great. More noticeable was the effect on adrenaline and especially growth hormone levels. The total amount of adrenaline and growth hormone in the blood during 2 hours was 2.7 and 10.7 times higher, respectively, than under control conditions.
Other research
Almost twenty years ago Danish scientist published a study in which the test subjects produced more growth hormone after physical exertion if the training had taken place at relatively high temperatures. [J Endocrinol Invest. 2003 Sep;26(9):838-42.]
