When the weather is cold, what is the reason why the old man's calf itches especially every afternoon?

There are many kinds of itching, one is that the weather is cold and the limbs are easy to itch, which is caused by dry skin.

If this is the case: don't take a bath often, the oil on your skin will easily run off. The bath water temperature is about 40 degrees, so don't overheat.

You can apply some lotion or olive oil to moisten it, which can relieve dry itching.
