The weather suddenly turns cold. What should I do if I have a headache?

1. Sometimes it hurts and doesn't work normally. However, now it doesn't hurt through exercise, and it feels good not to have a headache!

When the weather gets cold, everything changes with the expansion of heat and contraction of cold. People's heads are exposed, and blood vessels are affected. After contraction, blood circulation is not smooth and headaches are easy.

3. Take more exercise. Starting from September, walk 10,000 steps (calculated by pedometer) for about an hour at night, so that you won't have a headache in winter.

4. swim 1000 meters every day in summer or swim for an hour without stopping until it is too cold to swim any more, and you will not have a headache in winter. Swimming has greatly improved my cold resistance.
