As a result of the modern society work pressure, fast-paced life, the day is very nervous, so many office workers choose the night to relax themselves, often sleep in the early morning, in the long run, some men gradually found that when they get up in the morning that “a pillar of heaven” is not, and then the lack of interest in the opposite sex, slowly together with the room when there is a weakness of the heart. Many men do not realize that the reason they lose their “sexual happiness” is the lack of sleep. Recently, an American research institute recruited 10 men from the University of Chicago campus, who were 24 years old on average and in good health. Experts first tested their testosterone levels, and then asked the volunteers to sleep a fixed amount of time each day, ranging from 10 hours, 8 hours, 5 hours, and then draw blood to measure their testosterone levels again. It was found that when they slept for only 5 hours, their testosterone levels decreased by 10 to 15 percent. Testosterone is the most important androgen in the male body, and a lack of testosterone can cause loss of libido, lack of concentration, fatigue, etc. It can also affect muscle strength. Why does lack of sleep cause so much trouble for men? According to Chinese medicine, sleep is the time when the body’s yin and yang traffic, sleep well, then yang vigorous, energetic; while lack of sleep will appear mental weakness, fatigue, weakness, lower libido and other symptoms. Men are kidney-based and pay more attention to the role of yang energy compared to women, while sexual function directly reflects the strength of male yang energy. As men age, their physiological functions gradually decline and their Yang energy is slowly dissipated, from the “unknown female and male unity and made, the essence of the to also”, “a pillar of the sky”, to lifting but not firm, firm but soon. The normal daily sleep will ensure the recovery of Yang energy. Therefore, the seemingly ordinary sleep is very helpful to maintain normal male sexual function. How can I have a healthy sleep? One, first of all, to ensure sufficient time, adults should ensure 6-8 hours of sleep every day. More or less than this time is abnormal. Second, about when to start sleeping, the ancients used to say “sunrise, sunset and rest”, and nowadays, the work and rest is difficult to achieve, so traditional Chinese medicine, at least 11:00 p.m. before bed, the moment for the zi zhi, for the body just sprouting yang moment, so sleep before this, the body’s repair effect will be better. Third, for patients with sleep disorders, to maintain a good sleeping environment, but also to have a calm mood, “first sleep heart, then sleep”, this is the method told to us in the Song Dynasty “Cai Ji Tong sleep trick”. “No worries is to sleep party”, should be broad-minded, treat people with generosity and open-mindedness, grasp the emotions, to be the master of their own emotions, the heart is free of attachments, natural and peaceful sleep.
