What are common symptoms of heat exhaustion?

The symptoms of heat exhaustion typically involve a range of physical responses to prolonged exposure to high temperatures, particularly when combined with high humidity and strenuous activity. One of the hallmark characteristics of heat exhaustion is the individual's skin condition, which can present as hot, red, and either dry or damp, depending on the person's ability to sweat.

In heat exhaustion, the body tries to cool itself down, and sweat production can increase; however, if the humidity is very high, sweat may not evaporate effectively, causing the skin to feel clammy while still being warm to the touch. Conversely, if someone is dehydrated or unable to sweat properly, the skin may appear dry and red.

This symptom correlates with the body's attempt to manage its internal temperature, and these signs are crucial indicators that medical attention may be needed to prevent progression to heat stroke, a more severe condition.

In contrast, while cramps, nausea, severe headaches, fainting, rapid breathing, and chills may be associated with other heat-related illnesses or conditions, they are not the primary physical sign indicative of heat exhaustion as effectively as the condition of the skin. Thus, the skin's status provides a reliable gauge of someone possibly experiencing heat exhaustion.
