Taking a cold shower is not advisable, so caution should be exercised.

Firstly, taking a cold shower is not conducive to physical health.

Many people like to take cold showers in summer. Indeed, cold water baths can accelerate blood circulation and are beneficial to the skin and blood vessels. However, if you take a cold shower when you are sweating profusely, it will be detrimental to your health. Because when a person is sweating, the subcutaneous blood vessels dilate, the pores enlarge, and the blood circulation speeds up. If a cold shower is suddenly taken at this time, the subcutaneous blood vessels will immediately contract, the pores will close immediately, and the secretion of sweat glands will also stop immediately, blocking the body's heat dissipation channels. Once the body's heat cannot continue to dissipate, people will feel skin fever and are prone to catching a cold or other diseases. Therefore, it is best to use warm water when taking a shower after sweating in summer, and dry the body with a dry towel in time after taking a shower.

Secondly, Precautions for taking cold showers

1. The time for taking a cold shower should not be too long. When taking a cold shower, you should first touch the water on your limbs. When your body adapts to the transition, rinse the cold water on your chest and back to reduce the impact on your body. In addition, the temperature of cold water should not be too low, and the shower time should not be too long. This can help maintain good health.

2. It is not advisable to take a cold shower after strenuous exercise. After intense exercise, it is not advisable to take a cold shower because the capillaries on the surface of the body are in an expanded state at this time. Suddenly encountering cold water may increase the burden on the heart and cause symptoms such as palpitations, shortness of breath, and dizziness.
