Why does the body become stiff when the weather is cold?

When the weather is cold, blood vessels constrict, blood circulation slows down, and the body becomes stiff. The solution is to keep warm. You can increase your own body heat by warming yourself up by the fire, wearing more clothes, or using a hot water bottle to warm your baby. You can also eat hot pot and drink soju to warm your stomach. With more calories, blood circulation will increase relatively quickly, which is why it is especially easy to get hungry in winter. I don't know if I'm satisfied or not. In addition, blood circulation can be improved through large amounts of exercise.
