Why do hands and feet warm after long-term contact with cold water?

Hands and feet exposed to cold water for a long time will warm up, which is the body's defense function at work. I don't know if you have ever tried taking a cold bath in winter. Many of us advocate drinking cold water in winter. Drinking cold water can strengthen the body. Why does taking a cold bath in winter have this benefit? People who have taken a cold bath in winter must know that our bodies will become very, very warm after playing with cold water.

Taking a cold bath and getting warm when touching cold water is the process of adrenaline soaring in our body. We have a fever because the body feels cold, and then the body starts the function of self-defense. Then the body will get hot, and then the organs and cells in our body will get a warm environment to survive. Things in our bodies can't survive for a long time at the temperature of our cold water. Our normal cells and other organs and tissues. The temperature of normal life is about 37 degrees in our own bodies.
