Sleep is closely related to sex. Recently, research published in the American "Health" journal shows that poor sleep quality in men will affect erection, sleeping 6~8 hours a night can reduce the probability of erectile dysfunction in middle-aged and elderly men.
Sleep specialists at the Einstein College of Medicine in the United States monitor the volunteers' sleep status and nocturnal erections. It was found that the nighttime sleep mode was divided into two types, one was deep sleep, which lasted about 1.5 hours, and the other was light sleep, about 30 minutes, and the two modes were combined into a sleep cycle that lasted about 2 hours. During light sleep, men experience an erection. In general, it is necessary to repeat 4 cycles of sleep throughout the night, and men will also have 4 unconscious erections. This allows the penis to get enough rest, and the hormones in the body will be regularly regulated. Staying up late at night and sleeping irregularly can affect this sleep rule, not having an erection at night and in the morning, and until now there is a possibility of erectile dysfunction.
Previous studies have shown that sleep-deprived men have less sex and lower libido. Researchers say that the better the quality of sleep, the happier sex, both men and women. Sleeping 6~8 hours a day is the best secret to maintain sexual ability and physical strength.
Subsequent cigarettes also impair function
Recently, in the latest study in the UK, the harm of smoking after sex to the human body has increased significantly, 10 times the harm of cigarettes. The researchers pointed out that first of all, the nicotine in tobacco has a first excitatory and then inhibitory effect on the central nervous system, and carbon monoxide also has a great impact on the human body, reducing people's experience of wonderful sex.
In addition, the tar after tobacco combustion contains phenylpropane, vaginal dryness. Sexual life is a relatively intense exercise, sexual life muscles, bones, especially the nervous system is very excited, the blood vessels of the whole body are dilated, the blood flow is fast, and the energy consumption increases.
Smoking immediately after sex, the toxic substances in tobacco are easily absorbed into the body, which has adverse effects on cardiovascular and cerebrovascular health, and even causes angina pectoris and breathing difficulties
Finally, the nicotine in the smoke causes the smooth muscle of the corpora cavernosa of the penis to contract, destroy the blood vessels of the penis, inhibit blood flow, and thus affect the ability to erect.
