What are muscle pains created by physical work in hot environments called?

Muscle pains caused by physical work in hot environments are referred to as heat cramps. These cramps typically occur as a result of excessive sweating and loss of electrolytes, particularly sodium, which leads to involuntary and painful muscle contractions. Heat cramps can happen during intense physical activity in high temperatures, especially if the individual hasn't properly hydrated or replenished lost salts.

Understanding the nature of heat cramps is crucial for recognizing early signs of heat-related illnesses. By identifying muscle pain as heat cramps, workers can take proactive steps to cool down, hydrate, and rest to prevent the more severe conditions that could potentially follow, such as heat exhaustion or heat stroke. This distinction is important in a safety compliance context to ensure workers are educated and prepared to handle the risks associated with working in high-heat environments effectively.
