What is the most common form of heat stress?

Heat exhaustion is the most prevalent form of heat stress often encountered by individuals exposed to high temperatures, particularly during physical activity. This condition occurs when the body loses a significant amount of water and salt through sweating, leading to symptoms such as heavy sweating, weakness, dizziness, clumsiness, headache, and nausea. Essentially, it is the body's response to a combination of excessive heat and a depletion of electrolytes.

During heat exhaustion, the body is still able to cool itself through sweating, which distinguishes it from more severe conditions like heat stroke, where thermoregulation fails entirely. Recognizing the symptoms of heat exhaustion and addressing them promptly is crucial to prevent progression to more dangerous conditions. As such, it's imperative for individuals, especially in strenuous environments or activities during hot weather, to stay hydrated and take breaks to cool down, which can greatly reduce the risk of heat-related illnesses.
