Heatstroke, or sunstroke, is a condition where the body temperature becomes excessively high and the body can no longer regulate it. It usually occurs after prolonged exposure to heat or exercising in hot conditions. If not treated promptly, it can be life-threatening.

Causes of Heatstroke
1. Classic Heatstroke (from prolonged heat exposure)
Commonly found in the elderly, young children, or individuals with underlying health conditions.
It typically occurs in hot environments with poor ventilation, such as rooms without fans or air conditioning.
2.Exertional Heatstroke (from intense exercise in hot weather)
Often seen in athletes, soldiers, or people who work outdoors.
Intense physical activity generates excess body heat, which the body may not be able to dissipate fast enough.
Risk Factors for Heatstroke
1. Age – Older adults and young children are at higher risk.
2. Weather conditions – Hot and humid conditions with little airflow.
3. Intense physical activity – Especially during extreme heat.
4. Dehydration – Reduces the body’s ability to cool itself.
5. Alcohol – Contributes to dehydration and impairs body temperature regulation.
6. Certain medications – Such as diuretics, antidepressants, and blood pressure medications.
