Have you ever wondered why divers jump in the shower after every dive in the olympics? I have! That always bugged me when ever I watched the games, I mean, they had just got out the water and were soon to get back in - why waste the water? Well, after those years of wondering, here is the answer :D
According to Fourth Place Medal, the temperature of the pool water (usually around 80 degrees) and the air (between 68 and 72 degrees) are different. This difference can cause muscle tightness. So, to keep muscles nice and relaxed, divers warm up by taking showers or sitting in a hot tub.
