Overview

Heatstroke is a severe, life-threatening condition that occurs when the body’s temperature regulation system fails due to prolonged exposure to high temperatures or strenuous physical activity in hot environments. It is the most serious form of heat-related illness and requires immediate medical attention. Without prompt treatment, heatstroke can cause damage to vital organs such as the brain, heart, kidneys, and muscles.

Symptoms

Heatstroke symptoms often develop rapidly and may worsen quickly.

Common symptoms include:

  • Very high body temperature, usually above 40°C

  • Hot, dry skin or excessive sweating

  • Severe headache

  • Dizziness or lightheadedness

  • Confusion, agitation, or altered mental state

  • Slurred speech

  • Nausea or vomiting

  • Rapid heartbeat and breathing

  • Loss of consciousness or seizures in severe cases

Causes

Heatstroke occurs when the body is unable to cool itself effectively.

Common causes include:

  • Prolonged exposure to high environmental temperatures

  • Strenuous physical activity in hot or humid conditions

  • Dehydration reducing the body’s ability to sweat

  • Wearing heavy or tight clothing that traps heat

  • Poor ventilation or lack of access to cooling

Risk Factors

Certain individuals are more vulnerable to heatstroke.

Risk factors include:

  • Older adults and young children

  • People working or exercising outdoors

  • Dehydration

  • Obesity

  • Chronic medical conditions such as heart disease or diabetes

  • Alcohol or drug use

  • Certain medications affecting hydration or heat regulation

Complications

Heatstroke can lead to serious and sometimes permanent complications.

Possible complications include:

  • Brain damage affecting memory and coordination

  • Kidney failure

  • Liver damage

  • Heart rhythm problems

  • Muscle breakdown

  • Multiple organ failure

  • Death if untreated

Prevention

Heatstroke is largely preventable with proper precautions.

Preventive measures include:

  • Drinking plenty of fluids, especially water

  • Avoiding strenuous activity during peak heat hours

  • Wearing lightweight, loose-fitting clothing

  • Taking frequent breaks in shaded or cool areas

  • Using fans or air conditioning when possible

  • Never leaving children or pets in parked vehicles

  • Gradually acclimatizing to hot environments
