When our heart rate increases, speeding up our blood flow and warming us up, that is the cue for our bodies to release sweat. When sweat evaporates off the skin, it serves as a cooling mechanism to prevent overheating. Even though we sweat when we feel our hottest, it’s actually our body’s way of helping us cool down.

What is a good sweat rate?
