Winter swimming is to improve the body's resistance through cold stimulation. Too long cold stimulation will exceed the body's endurance and damage the body. Therefore, it is generally recommended that winter swimming 15~20 minutes is appropriate.

Everyone's physical condition is different, and the length of time they can bear is different. People who are physically strong and swim in winter all the year round can bear it for longer. Those who have just started swimming in winter should still do it step by step.

Change clothes in time after winter swimming and put on warm clothes.
