1, be sure to take a shower after a long run, as long as you are careful not to catch cold after taking a shower (the pores of the human body open after being heated, and it is really easy to catch cold). Rheumatism is yin cold to the bone.

2. Take a bath after running in winter, but use bath lotion instead of cleaning products such as alkaline soap to avoid completely removing the protective oil on the skin surface. Just wash the sweat off. Sweating after running, how can you not take a shower? As long as you can wash.

My calf itches in winter, too. Just apply some hand cream.
