When old folks here see you with a dripping shirt after a physical exertion, they would tell you to change clothes or take a bath. Letting your shirt dry while you are wearing it may give you spasm - that is an ailment where you get involuntary movement of your fingers, limbs or any other part of your body. Some people believe in that. And to be on the safe side, we just follow that advice to take a bath while the shirt is still wet or to change clothes. Take note that we are in a tropical country.
