Showering divers?

IPBiz will leave this statement, relating to "why" divers shower, for later:

Divers shower in between each dive to keep their muscles warm after getting out of the pool. The temperature of the pool water and the air are usually different (the pool is usually around 80 degrees, with the air temperature between 68 and 72 degrees). This difference can cause muscle tightness. To combat this, divers warm up in either the showers or a hot tub.
