don’t take a hot bath before sex
For men, it is very harmful to have sex immediately after taking a hot bath, especially after a long bath.
First of all, a large amount of hot gas in the bathroom will affect the normal breathing of the human body, leaving the body in a relatively hypoxic state, so it will inhibit the excitement of the sexual central nervous system and reduce the pleasure of sexual life.
Secondly, hot water will dilate the blood vessels of the skin and muscles, and a large amount of blood will flow into these parts. The blood supply and oxygen supply of important organs such as the heart and brain will be reduced. At this time, if you have sex immediately, the congestion of sexual organs and limb movement will further aggravate the hypoxia of the heart and brain, make the human body feel uncomfortable, dizziness, rapid heartbeat, etc., and even induce heart disease in serious cases.
Again, the skin is sensitive to temperature. Too cold or too hot will reduce the sensitivity of the skin and reduce the pleasure of sex.
Finally, hot water immersion will affect the number and quality of sperm, which is not conducive to eugenics.
Therefore, men should not have sex immediately after taking a bath. It is better to drink some water first and rest for half an hour. They can also use this time to do some foreplay and gradually enter the state of sex. In addition, the temperature of hot water bath should not be too high, preferably below 38 ℃.
It is worth reminding that men should not get up and wash immediately after sex. Because of the strong stimulation during sex, men will feel tired and sleepy. If they get up to take a bath, they may be exhausted and prone to dizziness and nausea. At this time, you’d better lie in bed and rest for half an hour.
don’t take a hot bath before going to bed
In life, we often make empirical mistakes in some small things. For example, most people think that taking a hot bath before going to bed can not only relieve fatigue but also help sleep. But from a health point of view, there is a problem.
it is difficult to fall asleep, and it is easy to dream after falling asleep
“Before going to bed” and “hot water” in “taking a hot bath before going to bed” are both wrong concepts and violate the physiological laws of the human body. Hot water for bathing will rapidly increase the temperature of the human body, which will inhibit the secretion of melatonin in the brain and slow down the time for the brain to release melatonin. The main role of melatonin is to induce natural sleep and overcome sleep obstacles by regulating people’s natural sleep. People want to sleep at night, mainly because it is only secreted at night. Melatonin secretion is most vigorous from 11:00 at night to 2:00 in the morning. After that, the secretion will slowly decrease until it stops at about 8:00 in the morning. If you go to bed immediately after taking a hot bath, melatonin will not be secreted, making it difficult to fall asleep. Even if you fall asleep, the quality is not high, and you may often dream.
The smart way is to skillfully arrange the time for taking a bath and preparing to go to bed. Take a bath an hour and a half before going to bed. After taking a bath, you can lie in bed and read a magazine, drink a glass of milk, or chat with your family. In this way, when you go to bed, your body temperature just drops to a temperature suitable for sleep, and your drowsiness will naturally come. You can enjoy a high-quality and comfortable sleep. When you wake up the next morning, you will feel especially refreshed, It’s better not to take a hot bath half an hour before going to bed. If you go to bed too late and want to take a shower before going to bed, it is recommended to lower the water temperature appropriately, or the water temperature should be hot first and then cool, so as to reduce the body temperature before the end of bathing. After bathing, apply cold water and cold towels to your forehead.
don’t take a hot bath immediately after exercise.
Many people like to take a hot bath to decontaminate immediately after exercise. In fact, their physical condition has not yet returned to a stable state after exercise. It is not appropriate to take a bath immediately, especially in hot baths and saunas.
Because bathing immediately after exercise will lead to an increase in blood flow to muscles and skin, and insufficient blood supply to other organs. At the same time, breathing is not stable after exercise, and then you enter the bathroom. In the case of poor air circulation, it is easy for the brain to lack oxygen, which may lead to dizziness, general weakness and other symptoms. In serious cases, it may also cause a drop in blood pressure, collapse shock and syncope.
Experts said that after exercise, it is best to rest for 30-45 minutes and then take a bath. Warm water shower should be completed in 5-10 minutes. The water temperature should not be 36-39 ℃, especially for people with weak physique.
