As much as I love watching Olympic diving, I've never understood why athletes hurry off to the showers and then proceed to relax in a hot tub (热水浴池) after each dive. They're already wet. They're only in the pool for a handful of seconds, so it's not like they need to get cleaned up. And doesn't taking a shower serve the same purpose as sitting in a hot tub?

Actually, that's what Olympic divers usually do between dives as they know very well about the importance of warm-ups and cool-downs. So, what's the actual reason?

As it turns out, showers and hot tubs are used pretty interchangeably by the swimming pool. However, there is a need for both. First, let's start with why divers need to take a shower between dives. It has to do with body temperature and keeping their muscles relaxed.As you can imagine, practicing dives in the pool, then having to keep your body warm in a shower, and then jumping off a 10-meter platform and into cold water couldn't be comfortable for anyone. Going back and forth between these warm and cool temperatures can cause a diver's muscles to tense or cramp up(痉挛)，which can lead to injuries to the muscles. Showers allow an Olympic diver to recover and prevent that.

In that way, showers and hot tubs serve the same purpose. A hot tub is generally used if you have a bit more time between dives and have already stretched. The shower walls on the pool deck can typically provide enough space for more divers at the same time, and they're especially helpful for athletes who need to stretch or who only have a few minutes be tween dives. Just like Olympic swimmers depend on thick clothes to keep their muscles warm, Olympic divers rely on these methods to stay loose. If you ask me, it's not a bad way to pass the time!
