Sleep and sex are closely related. Recently, a study published in the American "Health" magazine found that poor sleep quality in men can affect erections. Sleeping for 6 to 8 hours every night can reduce the chance of erectile dysfunction in middle-aged and elderly men.

Sleep experts from Albert Einstein College of Medicine in the United States monitored the volunteers' sleep conditions and nocturnal erections. It was found that there are two types of sleep patterns at night, one is deep sleep, which lasts about 1.5 hours, and the other is light sleep, which lasts about 30 minutes. The two patterns combined form one sleep cycle, which lasts for 2 hours. During light sleep, men will have erections. Generally, it takes 4 cycles to sleep throughout the night, and men will also have unintentional erections 4 times. This allows the penis to fully rest and the hormones in the body to be regulated regularly. If you stay up late at night or sleep irregularly, this sleep pattern will be affected, resulting in no erection at night and early in the morning. If things go on like this, it may also cause erectile dysfunction.

Previous studies have found that men who don't get enough sleep have less sex and have lower sexual desire. Researchers say that for both men and women, the better the quality of sleep, the happier the sex. Sleeping 6-8 hours a day is the best secret to maintaining sexual performance and physical strength.

A cigarette afterwards can also damage sexual function

Recently, a latest British study found that smoking after sex will greatly increase the harm to the human body, which is ten times more harmful than usual tobacco. Researchers pointed out that first of all, nicotine in tobacco has an excitatory and then inhibitory effect on the central nervous system. Carbon monoxide also has a great impact on the human body. They will all reduce people's experience of wonderful sex.

In addition, the tar after burning tobacco contains phenylpyrene, which can cause vaginal dryness. Sex life is a relatively strenuous exercise. During the process of lovemaking, muscles, bones, and especially the nervous system will be extremely excited, blood vessels throughout the body will dilate, blood flow speed will increase, and energy consumption will increase. If you smoke immediately after sex, the toxic substances in the cigarette can easily be absorbed into the body, which will have adverse effects on cardiovascular and cerebrovascular health, and even lead to angina pectoris and dyspnea.

Finally, the nicotine in smoke will cause the smooth muscles of the corpus cavernosum to contract, damage the blood vessels of the penis, inhibit blood flow, and thus affect the ability to have an erection.
