How to prevent frostbite? Northerners are going to the south.

Let me tell you, that's your peripheral blood circulation! When I was a child, I was frozen stiff. People say it freezes every year,

I don't believe in evil, so I try to protect it. It hasn't been frozen for 7-8 years, has it?

Don't expect any medicine. I have used it all. It's no use. There's only one way. Try to keep your hands and feet warm all the time. I'm talking about external force, because you must be cold when it's cold. For example, take a thermos bottle, wear gloves, use hot water to burn your hands, and rub your hands if you have nothing to do.

This is the most practical method. Don't be afraid of jokes.

The above is my most practical experience. I am a personal patient, and now I have recovered. When I was a child, my hands often rotted, and now it has not been frozen for 10 years. Believe me, I will try my method.
