Blood supply to other parts will be relatively reduced, and many parts of the body will be colder, so you will feel cold.

B, the principle of exercise, while exercising, it produces a kinetic energy, which produces a heat energy, so the body will feel the heat in the process of heat release.

How to reduce fever:

A, if it is a low-grade fever, first of all, drink plenty of water, boiled water is the best, and pour water in a large cup until it is no longer available. Go to the toilet a few times more, and the body virus will have been discharged.
