How about taking a hot bath on a hot day?

The water temperature is 34℃-36℃, which is beneficial to decontamination and itching relief; 37℃-39℃, which is beneficial to eliminate fatigue; 40℃-45℃ can relax muscles and tendons, promote blood circulation, sweat and relieve pain. The temperature of the bath water can be adjusted according to the time. For example, you can choose to take a hot bath in winter and a warm bath in summer. If the bath water is too hot and the temperature is too high, it will not only damage the skin, but also dilate the blood vessels on the skin surface, increase the blood flow on the body surface, reduce the blood supply to the heart and brain, and often lead to the danger of hypoxia and fainting. Moreover, the water with too high temperature will make the pores open quickly and let the bacteria accumulated in a day quickly enter the skin. Washing warm water is the best, it won't irritate the skin, and it will have a cool feeling. If you like hot water, you can let the water temperature rise slowly in the bath. However, it is recommended that the water temperature should not exceed 45 degrees Celsius.
