When it is hot, my body often itches. Why?

It's the dry skin. It's not the sweat that itches, but the clothes you wear. If it is made of sweater, chemical fiber or silk, it is easy to generate static electricity, so you will feel itchy.

It is recommended not to take a bath frequently, because it will speed up the dehydration of the skin (soap or shower gel will take away moisture from the skin more easily), but you can take a bath every day (just rinse with water, don't apply soap, etc.). ), it can make the skin absorb more water, and it is still possible to apply lotion after taking a shower.

Also, close-fitting clothes must be cotton (at least 80% of the ingredients are cotton), and try not to wear sweaters (it is necessary to wear them because it is too cold, after all, health is the most important), which should be better.
