Does it make sense to wear a swimming cap?

There are situations in which wearing a swimming cap makes perfect sense. For example, to protect the hair from chlorine, salt water and other chemicals in swimming pool or sea water. This is particularly important for people with colored hair, as chemicals can dry out and damage the hair. Some swim caps also cover the ears, providing protection from water and possible infection.

Wearing a swimming cap also reduces water resistance, which is important for competitive swimmers. Reducing water resistance and thus improving glide in the water can lead to better performance.

Swimming caps also improve hygiene in the pool as they prevent hair from getting into the water.
