A Possible Explanation of the Connection of Poor Sleep and Increased Physical Exercise

It is my hypothesis that low DHEA may trigger cancer (Annals of Internal Medicine 2005; 142: 471-472). Cancer occurs most often in old age when DHEA has declined to very low levels.

It is also my hypothesis that the function of sleep is to increase DHEA. Poor sleep would indicate a situation of poor DHEA production. While it is known that exercise increases DHEA and is the reason, I suggest, that exercise reduces cancer risk, exercise, according to my work, also uses DHEA. Individuals who exercise excessively, especially if they are not sleeping well and producing sufficient DHEA, might actually use more DHEA than they produce. This reduces DHEA and increases cancer risk.

I suggest this new finding that poor sleep and excessive exercise increase cancer risk is caused by an overall reduction in DHEA.
