Heat stress occurs when the body cannot cool itself effectively, leading to an increase in body temperature. This condition can result from high environmental temperatures, humidity, and physical exertion. Symptoms may include heavy sweating, fatigue, dizziness, and headaches. If not addressed, heat stress can progress to more severe conditions like heat exhaustion or heat stroke. To prevent heat stress, it is essential to stay hydrated, wear appropriate clothing, and take breaks in cooler areas. Individuals working in hot environments, such as construction sites or agricultural fields, should be particularly vigilant. Recognizing the signs of heat stress can help ensure safety and well-being.
