中小学生游泳前需要做哪些准备？

Before you dive in, it is crucial to wash away any sweat, dirt, or cosmetics from your body. Taking a shower beforehand not only cleans you up but also helps prevent you from picking up germs in the pool. Additionally, cosmetics and sunscreens are chemical products that can negatively affect the water quality, so keeping them off your skin is a good idea for everyone.
