The weather is getting hotter, but these bathing methods are harmful to health

The weather is getting hotter and hotter. For many people, they have to take a shower before they feel comfortable when they get home every day covered in sweat. Taking a shower has become a daily routine for us to maintain physical hygiene and health in summer. But there are several bathing methods that you need to be careful about. Avoid them if possible, otherwise they will be harmful to your body.

Like to take a long bath: Some people like to take a bath, and even listen to music in the bathtub. But taking a bath for too long is not good for your health. Taking a bath for too long can easily make people tired and cause ischemia and hypoxia of the heart. In severe cases, it can cause coronary artery spasm, thrombosis, and even induce arrhythmia and sudden death. In addition, if you bathe for too long, the blood supply to the head will be reduced, which can easily lead to cerebral ischemia and accidents. Therefore, if you take a tub bath, 20 minutes is enough.

Like to take hot baths: Generally speaking, the human body temperature is 40℃, so taking a bath with 40℃ warm water is the most ideal way to eliminate fatigue. If the water temperature is too high, more calories will be consumed, which will make people feel more uncomfortable; if the water temperature is too low, blood vessels will constrict, making it difficult to eliminate fatigue. During the dog days of summer, the water temperature can be lowered appropriately, but not lower than 35℃.

Go to bed immediately after taking a bath: Although taking a bath can improve sleep, it is not advisable to go to bed immediately after taking a bath. Because the body temperature will rise after taking a shower, it is not conducive to the secretion of "melatonin", a hormone that helps sleep. It is best to schedule a bath 1-2 hours before bedtime. After taking a bath, you can do a hydrating mask or listen to some light music, and then go to sleep peacefully after everything has calmed down.

At the same time, you need to pay attention to the fact that you must blow dry your hair before going to bed after taking a shower. If you sleep with wet hair as a pillow, it will not only seriously affect the quality of sleep, but also easily cause headaches.

Take a hot bath immediately after exercise: Many people like to take a hot bath immediately after exercise to remove dirt. In fact, the physical condition has not yet returned to a stable state after exercise, so it is not advisable to take a bath immediately, especially a hot bath or sauna.

Because taking a shower immediately after exercise will increase the blood flow to the muscles and skin, and other organs will not receive enough blood supply. At the same time, your breathing has not yet stabilized after exercise, and if you go into the bathroom right away, the brain will easily suffer from hypoxia in the absence of air circulation, which may cause symptoms such as dizziness, general weakness, and in severe cases, it can also cause a drop in blood pressure, collapse, shock, and fainting. Therefore, it is best to rest for 20-30 minutes after exercise before taking a shower. The warm water shower should be completed within 5-10 minutes. The water temperature should not be above 36-39℃. People with weak constitution should pay more attention to the water temperature.
