 What is Heat Stress?

Heat stress refers to the strain or burden that excessive heat places on the human body. It occurs when the body's natural cooling mechanisms are unable to maintain a stable internal temperature, typically due to exposure to high temperatures or prolonged physical exertion in hot environments. Heat stress can lead to various heat-related illnesses, including heat cramps, heat exhaustion, and heat stroke.

When the body is exposed to high temperatures, it tries to cool down by sweating and dissipating heat through the process of evaporation. However, in conditions of extreme heat or high humidity, sweat may not effectively evaporate, hampering the body's cooling mechanism. This can result in a buildup of body heat, leading to heat stress.

Heat stress can have detrimental effects on the body and may cause symptoms such as excessive sweating, fatigue, dizziness, headache, nausea, rapid heartbeat, and muscle cramps. If not addressed promptly, heat stress can progress to more severe conditions like heat exhaustion or heat stroke, which require immediate medical attention.

It is important to take preventive measures, such as staying hydrated, seeking shade, and avoiding excessive physical exertion in hot environments, to minimize the risk of heat stress. Recognizing the signs of heat stress and taking appropriate action, such as moving to a cooler area and rehydrating, can help mitigate its effects and prevent more serious heat-related illnesses.
