The human body needs to ensure adequate sleep every day to relieve the pressure of the day, in fact, the male penis is also the same, with the growth of age, the male penis will be erected more and more times a day, which is closely and inseparably related to age, physical fitness, sexual function, experts suggest that the penis should be properly rested to ensure adequate “sleep “. Insomnia makes people depressed, memory loss, concentration. More seriously, it also deprives men of the opportunity to “maintain” the penis and improve sexual performance. The medical term “nocturnal penis erection” refers to the spontaneous erection of the penis when a person is asleep, and normal men have this condition. The number of erections varies greatly depending on age, physical condition, and sexual function. In general, young men have seven or eight erections per night, which would theoretically be significantly higher than during the day. As we age, the number of erections decreases. Healthy, normal older men have about two or three erections per night. Penis maintenance cannot be achieved without good sleep Some studies have found that when the penis is erect, the oxygen tension in the cavernous body is three to four times higher than when it is weak. This high oxygen tension helps the metabolism of the endothelial cells of the cavernous body of the penis and promotes the normal recovery of sexual function. Therefore, male doctors like to image it as “charging the penis”. Men who sleep well have several opportunities to “recharge” each night to ensure that their sexual function is in good shape. When a person gets little or poor quality sleep, nighttime erections that facilitate “recharging” are less likely to occur or not occur at all. It is easy to imagine that the erectile function of these men is bound to decline with each passing day. In fact, in real life, not only insomnia patients, there are many often stay up late “night owls”, the quality of their sex life is often not as good as it should be. The reason for this is the same. For this reason, I hope that the majority of men should combine work and rest to ensure adequate and high-quality sleep. This is an inexpensive and efficient penis and sexual function “health care method”. The signs of penis aging Age, many aspects of people are changing, wrinkles, body shape rickety, even the penis is also “aging”. It is mainly reflected in the following four aspects: 1, the appearance of the penis has changed experts, men to more than forty years old, the glans will gradually lose the purple color, mainly because of the reduction of blood running. Due to the decline in androgen levels, the pubic hair of the penis will also become increasingly thin, gradually returned to the state of hairless before puberty. 2, size “shrinkage” with age, male weight gain is a common phenomenon. Experts say: “In some cases, the abdominal fat will bury the penis. The length and thickness of the penis, will also change a little. If a European or American man has a 15-centimeter-long erect penis in his 30s, he may only have about 12 centimeters by the time he reaches his 60s or 70s.” There are many causes of penis shrinkage, such as the slow deposition of fatty material (plaque) in the small arteries of the penis, which can impede the flow of blood to the tissues and organs, the same process as atherosclerosis, which is known to cause heart attacks when clogged in the coronary arteries. At the same time, inelastin is deposited in the elastic fiber sheath, will also make the erection of blood perfusion space is relatively small. 3, the penis is more “curved” If the scar accumulates unevenly, the penis may become more and more curved, which is called penile sclerosis, most often seen in middle-aged people. It can cause pain during erection and difficulty in sexual intercourse, so patients should actively seek medical attention. 4, penile insensitivity Many studies have shown that the sensitivity of the penis decreases over time, which can affect erections and delay orgasm.
