# What are the benefits of a swim cap?
A swim cap has several functions when swimming. Firstly, it protects your hair from chlorine and other chemicals in pool water. Chlorine can dry out your hair and make it brittle, so a swimming cap is particularly useful for people with colored hair. On the other hand, a swimming cap also ensures that the water is not contaminated with hair, which in turn contributes to better water hygiene.
A swimming cap also helps - and this is particularly important for open water swimmers - to minimize heat loss through the head. The swimming cap is therefore also heat protection.
The smooth surface of the swimming cap also reduces water resistance, which is particularly beneficial for competitive swimmers. By reducing the resistance, the swimmer can glide through the water faster.
