People like to take a hot bath and feel very comfortable. In fact, the bath temperature should be appropriate, neither too hot nor too cold. The water temperature is too hot, which makes people sweat, especially in winter. When you go out after taking a shower, cold air blows on your face, which easily leads to illness. Showing a little sweat is not only easy to clean the skin, but also makes people feel comfortable. But when it comes to sweating, it is inevitable that your heart is short of breath and your mouth is dry. A tired body touching the cold wind is naturally a health taboo. ?

Modern health care scholars have confirmed that the bath water temperature is too high, which can cause "bath house syndrome" of middle-aged and elderly people, such as dizziness, dizziness, palpitation, nausea and even fainting. This is because the bath water temperature is too high, the middle-aged and elderly people move slowly, and the soaking time is too long, which greatly expands the blood vessels on the body surface and limbs, and the blood flows to the body surface and limbs in large quantities, resulting in ischemia and hypoxia of the brain and coronary artery. Visible, bath water temperature is too high, generally should be 30℃-37℃ is appropriate. ?

For young men, the bath water temperature is too high, which will hinder the sperm development of germ cells. Taking a hot bath in the bathtub 1 hour will damage people's fertility for 6 weeks. Foreign researchers found that the number, motility and penetration of sperm decreased significantly after healthy men were soaked in bath water at 29. 1℃/hour. After 36 hours of hot water bath, the above injuries can still be seen when semen is taken. In fact, the water temperature of many people's baths is far more than 29. 1℃, but above 40℃, which greatly increases its harm. ?

The bath temperature of pregnant women in the first trimester should not be too high. According to the research of a foreign medical expert, hyperthermia in pregnant women (especially in the third month of pregnancy) has a bad effect on embryo development. He believes that hyperthermia itself is one of the important causes of human congenital malformation. Since then, medical experts have confirmed that during pregnancy, no matter what causes the body temperature to rise, such as taking a hot bath, working at high temperature and having a fever, it may cause obvious harm to the central nervous system of the fetus. According to relevant data, in recent years, experiments have proved that if a pregnant woman's body temperature is soaked in hot water at 45℃ for more than 20 minutes, her body temperature can rise above 38℃, which will undoubtedly cause harm to the fetus. Therefore, pregnant women should try not to take a hot bath before 100 days of pregnancy, especially not to soak in hot water for a long time.

Generally speaking, it is ok to take a hot bath every day. If you take a long bath every time, it will do great harm to human body.
