Signs of Heat Exhaustion
6. Fatigue
People are often flummoxed about why hot weather brings about fatigue or tiredness. However, the explanation is simple. On any given day, your body works to regulate your temperature. That job is somewhat easier in colder environments, but when the temperatures rise, your body’s cooling mechanisms are kicked into overdrive. If you work outside, then the process becomes even more complicated.
There are several things that your body does to control and maintain its temperature. One of the most important is called vasodilation. During this process, your body has more blood to flow near the surface of your skin, which allows warmer blood cells to release heat and cool off. Unfortunately, in extreme situations and in combination with other symptoms, this process can lead to severe fatigue and heat exhaustion.
