How does sweating assist in thermoregulation

Sweating cools us down in two ways. Firstly sweat is wet so it cools down your body. Secondly, it evaporates which takes away some of our body heat. We sweat when we're hot and it helps to bring our internal temperature levels lower when it gets too high on a hot day, therefore assisting in thermoregulation.

Sweat is just salty water. when you get hot, you sweat. the sweat helps cool you down
