Cold water bath is to stimulate the human body with cold water below the body surface temperature, and enhance the metabolism and immune function of the human body. Cold water can stimulate the body to generate more heat to resist the cold, so it consumes the body's heat. But you said that you still left a lot of sweat during exercise when you took a cold shower, which is not recommended. Because the pores were dilated at that time, the stimulation of supercooling would bring some pressure to the pores and skin. Over time, you have become accustomed to this kind of pressure, and you may have such a stimulating feeling after washing with hot water.
In addition, please pay attention to the following points when taking a cold bath. If you make a mistake in this respect when taking a cold bath, it is likely to cause other diseases, so I suggest that you find something wrong after comparison and should go to the hospital for relevant examination:
Please note the following points:
1, people who have never taken a cold bath before, if they suddenly take a cold bath, their blood vessels will contract, their body temperature will drop, and their bodies will catch cold, leading to colds. Therefore, taking a cold bath should start in summer, last from summer to autumn, and last until winter, and it is best not to interrupt during the period.
2, it is best not to take a cold shower, because the respiratory system is concentrated there, it is easy to cause respiratory diseases due to cold, and it is necessary to keep your head dry when taking a cold shower.
3. Take a bath with very cold water. After a long time, the skin will get frostbite and frostbite. Therefore, the time for taking a cold bath varies from person to person, from time to time. Not too long. The lower the temperature, the shorter the water bath time. Wash for 3-5 minutes at most in winter. And after taking a bath, dry your body with a dry towel and rub red.
4. After taking a cold shower, carefully wipe the joints of the whole body with a wet towel.
Take a cold bath when you are in good health. Stop taking a cold bath when you are unwell, such as catching a cold.
