Why do Olympic swimmers wear two swim caps?

Hungarian swimmer Katinka Hosszu continues to show impressive performance at the Rio 2016 Olympics.

No matter how much you wear a bathing suit, how to jump from a board or how to wear hair on the head, swimmers often try to do everything possible to swim as quickly as possible.

But surely you have never seen anyone wearing two hats swimming at the same time.

Some Olympic swimmers wear two hats to speed up.

SB Nation - a well-known American news agency revealed that Hungay athletes - Katinka Hosszu, who won a gold medal in swimming at the Rio 2016 Olympics, took off her hat, she still wore another hat below. :

Katinka Hosszu wore two hats to swim in the pool.

Not only Katinka Hosszu, other swimmers like the American Swimmers Team: Michael Phelps and Katie Ledecky or Sun Yang - Chinese athletes receive a gold medal for free 200-meter swim content. Men, they all wear two swimming caps while competing.

In the meantime, people always assume that carrying more and more things on people will make the athlete swim slower. But is that thought true or not? During the 2012 Summer Olympics in London, Pauline Vu elaborated on this " strange move " on Yahoo.

The first reason is simply: It helps athletes to keep the goggles swimming tight on their heads to avoid falling into the water. Any athlete will tell you: " One of their biggest problems is the water-filled swimming goggles ." Adding a swim cap can help that athlete's swimming goggles stay in place.

Two hats are made of two different materials.

The second more interesting reason is that each swim cap is made of different materials to be able to support each other. In particular, the first hat is made of latex. It can remain fixed on the head but is often " wrinkled ". The second hat is made of silicone to avoid wrinkles. Because the less wrinkled hats are, the athletes do not have to adjust their hats much and can swim faster.

Pauline Vu noted: " Although not everyone does it, it is increasingly asserted: Swimming is not just a sport but it is an art form ."
