Heat Exhaustion Alert: Know the Warning Signs to Stay Safe This Summer

With rising temperatures, recognizing the symptoms of heat exhaustion is crucial to avoid serious health risks. Heat exhaustion occurs when the body overheats from prolonged exposure to high temperatures, particularly in humid conditions or during intense physical activity. Dr. Vandana Garg, Senior Consultant in Internal Medicine at Max Super Speciality Hospital, Vaishali, explains the key signs and preventive measures.

One of the earliest indicators of heat exhaustion is excessive sweating—the body’s natural cooling mechanism. Alongside this, the skin may appear pale, cool, and moist, while muscle cramps—often in the legs or abdomen—can develop. Feelings of extreme tiredness, weakness, and overall discomfort are also common.

Dizziness or fainting may occur due to dehydration reducing blood flow to the brain. Other symptoms include headaches, nausea, vomiting, a fast but weak pulse, and confusion. If someone shows these signs, immediate action is necessary. Move them to a shaded or air-conditioned area, provide water or an electrolyte drink, and use cool, wet cloths or fans to bring their temperature down. If symptoms persist beyond 30 minutes or worsen, seek emergency medical help, as heat exhaustion can escalate into life-threatening heatstroke.

High-risk groups include older adults, young children, individuals with chronic conditions, and outdoor workers. Preventive steps like wearing light clothing, drinking plenty of fluids, and avoiding strenuous activities during peak heat can reduce the chances of heat exhaustion.

Being aware of these warning signs and responding promptly can save lives. As summer temperatures climb, vigilance and quick action are the best ways to protect yourself and others from heat-related illnesses.
