Sleep is extremely important for any person, regardless of gender and age. It is necessary for recuperation, for deep rest of the body. However, in men, sleep is directly related to the release of the main male sex hormone, testosterone. And it is he who is responsible for men’s health. If the representative of the stronger sex does not get enough sleep, then he simply will not have enough strength for nightly “exploits”. Moreover, lack of sleep will immediately affect potency. The entire hormonal background will suffer, as well as the cardiovascular system will be strongly affected.
