If you know history, you will know that our great Chairman Mao bathed in cold water since he was a child and was in good health.

In fact, there is a limit to taking a cold bath. If you only do it after exercise, or when you have a cold, or when the weather is too cold, it will definitely be bad for your health.

A cold bath is suitable for some strong people. For people with poor constitution and low immunity, it is better to use warm water as much as possible.

However, taking a cold bath is good for accelerating blood circulation, just like swimming in winter. In the long run, blood flow is fast, metabolism is accelerated, and waste is discharged, which is beneficial to health.
