Answer 2

Swimming requires fast movement and tactical movement of hands and legs to push water aside/behind to get a forward force. In this u have to keep ur upper body straight in a streamline manner.
In doing so u can face:
1. Muscle pain as ur muscles get streched. Back and thigh gets affected the most.
2. Cold and various diseases if the water in unclean.
3. Drowning beacuse of heart attack or brain problems.
4. Tanning of skin due to the disinfectant chlorine which reacts with fats present on our skin. etc
