Some studies have concluded that lack of sleep can lead to decreased testosterone levels in men. Testosterone is the steroid hormone that plays an important role in libido, energy, muscle mass, bone density and immune function. Scientists have learned a number of things about the interrelationship between sleep quality and human aging and sex hormones. For example, starting in the 20s or 30s, men’s testosterone levels decrease by 1 to 2 percent per year. Lack of sleep in younger men can lower sex hormone levels. Sleep is a tremendous source of health. How can men get a good night’s sleep? To this question, male experts remind men to develop good habits of going to bed and getting up on time, following the objective rule of alternating sleep and wakefulness. This will stabilize the sleep and avoid causing excessive fatigue of the cerebral cortex cells. In addition, do not perform intense mental work before going to bed and avoid strenuous exercise or physical work. Instead, you should take a walk outdoors. Do not eat dinner too late or too much, you should eat light food that is easy to digest, pay attention to eating more vegetables and a certain percentage of mixed grains, and keep your bowels open. Seasoning should not be used too heavily. You should not smoke, drink stimulating drinks such as strong tea or coffee, or drink too much drink or flow juice at night. Cigarettes, tea and coffee will stimulate the brain and make it less likely to enter a state of inhibition. And drinking too much flow juice will lead to an increase in the number of urine, which is not conducive to falling asleep again. It is known that it is necessary to brush your teeth and wash your face before going to bed, but also to develop the habit of washing your feet with warm water. Wash your feet with warm water for 15 to 20 minutes before going to bed, so that the blood vessels in the feet expand, which can promote blood circulation in the lower limbs and is conducive to sleep soon. When available, you can use warm water to rub your body or hot water bath. Take off your outer clothes before going to bed, change your underwear at the right time, wear loose outer clothes if you can, keep your bedding clean and dry it often to keep it dry and kill bacteria. People also easily lose their sexual enthusiasm if they don’t get enough sleep. Our traditional Chinese medicine theory believes that sex and sleep are both closely related to heart energy. A strong heart means a high quality of sleep, while a good sleep can also make the heart “recharge”. If there is a lack of sleep, heart energy will be reduced, sex drive and sexual ability will also be reduced. So instead of eating health supplements, it is better to set aside enough time to sleep beautifully overnight, sufficient sleep, full of spirit, will make male friends more relaxed, better physical strength, more harmonious life.
