Outdoor workers, particularly those in agriculture and construction, are at high risk of heat-related illnesses during hot and humid conditions. Heat exhaustion can lead to symptoms like nausea, muscle cramps, and excessive sweating, while heat stroke is a life-threatening condition marked by high body temperature, confusion, and potential loss of consciousness. Workers with pre-existing health conditions or those taking medications may be more sensitive to heat, increasing their vulnerability. Without proper precautions, prolonged exposure to extreme heat can result in severe health complications or fatalities.
