It's a little cold now. Is it harmful or beneficial to continue taking a cold bath?

A cold water bath has three advantages.

First, increase the adaptability of human body to temperature, especially to cold air, so as to avoid catching a cold.

Secondly, it is a good exercise for human blood vessels. When taking a cold bath, the blood vessels contract rapidly, and a large amount of blood flows to the inside of the body and then to the body surface, and the blood vessels expand and contract. In the long run, cardiovascular diseases can be prevented.

Third, it can exercise people's will. Bathing in summer is enjoyable, and bathing in winter requires perseverance.

But some people are not suitable for washing, such as:

1. Hypertensive patients: When the skin comes into contact with cold water, the blood vessels contract sharply, and a large amount of blood rushes back to the internal organs, and the blood pressure rises.

2, sciatica, arthritis patients: after the nerves catch cold, the condition will be more severe.

3. People who are allergic to cold.
