What are the symptoms of heat exhaustion?

The symptoms of heat exhaustion primarily include heavy sweating, rapid breathing, and dizziness, all of which are indicative of the body struggling to cool down due to excess heat exposure. Heavy sweating occurs as the body attempts to dissipate heat, while rapid breathing can be a response to the body's increased demand for oxygen in order to cope with elevated body temperatures. Dizziness often accompanies these symptoms as the body can experience a drop in blood pressure and dehydration, which can lead to feelings of light-headedness or faintness.

In addition to these, heat exhaustion can also cause other symptoms such as weakness, excessive thirst, and a pale, clammy skin appearance, further affirming that these specific signs are critical to identify the condition. Recognizing these symptoms is important in order to take prompt action, such as moving to a cooler environment and rehydrating, to prevent the progression to more severe heat-related illnesses, such as heat stroke.
