Is it better to wash hot water or cold water in this weather?

It is best to use cold water, which is good for the skin and will improve the body's resistance and adaptability! At first, it is easier to detoxify when the pores are open, and then use warm water later, and then turn it into cold water, so that the skin will become very elastic after repeated water changes. It is difficult to avoid sweating after exercise in summer, especially when you are sweating all over. A hot bath is better than a cold one.

After exercise, some people take a cold bath from head to toe in order to have a good time. At that time, they felt carefree, but afterwards they are likely to feel tired, and some even have headaches. This is because when the body sweats a lot, the capillaries are dilated. If you take a cold bath, the blood vessels contract sharply, and the heat in the body is restrained by external forces, so it cannot be emitted for a while. Moreover, intracranial arteries are rich and sensitive to external stimuli. In hot season, the head is particularly prone to sweating after exercise. If you wash your hair with cold water, it may cause abnormal intracranial vascular function, leading to dizziness, headache, blackness at the moment and even vomiting. It can be seen that it is dangerous and undesirable to take a cold bath to quickly cool down, especially for people who are not used to taking a cold bath. When their bodies suddenly get cold, they often cause all kinds of discomfort. I suggest that you don't try to feel refreshed for a while, leaving hidden dangers of disease.

For most people who are not used to taking a cold bath, it is better to take a hot bath after exercise in summer. Bathing with hot water can wash away sweat, keep hair follicles and skin clean, ventilate the skin, accelerate blood circulation of skin and muscle vessels, dilate capillaries, help the body expel heat, promote metabolism, nourish all parts of the skin, and accelerate the removal of metabolites such as lactic acid. After the blockage on the skin surface and sweat pores is removed, the skin can sweat smoothly, and the smooth "breathing" of the skin is beneficial to the regulation of body temperature. In addition, a hot bath at a proper temperature can soothe the nerves, relax the muscle tissue of the whole body, and even play a certain role in calming, relieving itching, relieving pain and resisting allergy. Although you will sweat more when it is hot in summer, you may feel hotter after taking a hot bath, but you will feel cool and comfortable after a short rest and enjoy that refreshing feeling.

The temperature of hot water bath should not be too high, and warm water of 35 ~ 40℃ is generally suitable. The number of times of washing should not be too much, because too many times will wash off all the oil normally secreted on the skin surface and the protective flora normally parasitic on the skin surface, which will easily cause skin itching and other diseases, and the skin's resistance will be weakened, but it will easily get sick.
