Cooling down through perspiration

It was a hot day yesterday during our tennis practice, and we were all sweating a lot.  I was mindful that this process was a way for the body to cool down, it is a mean of thermoregulation. After the body excretes the sweat, it evaporates. This evaporation has a cooling effect due to the latent heat (the heat released) of water.
