1. You can't take a shower immediately after a lot of exercise.

After strenuous exercise, in order to keep the body temperature constant, blood vessels on the skin surface expand, sweat pores expand and sweat increases, which is beneficial to heat dissipation. At this time, if the cold water bath is suddenly stimulated, the blood vessels will contract immediately, the blood circulation resistance will increase, and the body's resistance will decrease, and people will easily get sick. If you take a hot bath, the blood flow to the skin will continue to increase, and too much blood will flow into the muscles and skin, resulting in insufficient blood supply to the heart and brain, dizziness in the light, collapse and shock in the heavy, and other chronic diseases will be easily induced.

Therefore, it is best to eat more foods containing vitamin B 1 after strenuous exercise, such as coarse grains, vegetables, liver, eggs and so on.
