What is heat stroke (sunstroke)?
Heat stroke, also called sunstroke, is the most severe form of heat-related illness. It occurs when prolonged exposure to high temperatures or intense physical activity overwhelms the body's ability to regulate its temperature. Body temperature can rise to 104°F (40°C) or higher, causing the body’s normal cooling mechanisms to fail. Heat stroke is a medical emergency that requires immediate treatment to prevent serious complications.
Pro tip
What are the two types of heat stroke?
Heat stroke is generally classified into two types based on how it develops and what triggers it:
| Type | Cause | Who Is at risk |
|---|---|---|
| Exertional heat stroke | Develops from intense physical activity in hot conditions, causing a rapid rise in body temperature. | Athletes, outdoor workers, and people performing strenuous activities in high temperatures. |
| Classic heat stroke | Results from prolonged exposure to high temperatures, overwhelming the body’s ability to regulate temperature. | Older adults, young children, and people with certain chronic health conditions. |
Heat stroke vs heat exhaustion: what's the difference?
Heat exhaustion and heat stroke are both heat-related illnesses, but heat stroke is more severe and requires immediate emergency medical care.
- Heat exhaustion: It causes heavy sweating, weakness, dizziness, nausea, headache, and a rapid pulse. Body temperature may rise but generally remains below 104°F (40°C). Prompt cooling, rest, and fluid replacement are important.
Heat stroke: It occurs when the body temperature reaches 104°F (40°C) or higher. Symptoms can include confusion, altered mental status, seizures, or loss of consciousness. Skin may be hot and dry, although sweating can still occur. Immediate emergency treatment and rapid cooling are essential to reduce the risk of organ damage or death.
What are the signs and symptoms of heat stroke?
Heat stroke requires immediate medical attention. Symptoms can develop rapidly and may affect the brain, circulation, breathing, and skin. Common signs include:
| Symptom | Description |
|---|---|
| High body temperature | Body temperature reaches 104°F (40°C) or higher. |
| Altered mental state | Confusion, agitation, disorientation, unusual behaviour, or loss of consciousness may occur. |
| Headache | A severe or throbbing headache may develop. |
| Hot, flushed skin | Skin may become hot, red, or flushed, with reduced or absent sweating. |
| Blurred vision | Vision may become blurred or impaired. |
| Slurred speech | Difficulty speaking clearly may occur due to neurological effects. |
| Nausea or vomiting | May cause nausea, vomiting, or stomach discomfort. |
| Rapid heartbeat | Heart rate may increase as the body responds to extreme heat. |
| Low blood pressure | Severe heat stroke can cause blood pressure to fall. |
| Rapid, shallow reathing | Breathing may become fast and shallow as the condition worsens. |
| Seizures | Severe heat stroke can cause seizures and loss of consciousness. |

Who is more vulnerable to a heat stroke?
Several factors can increase the risk of heat stroke, particularly during prolonged exposure to high temperatures:
- High temperatures: Extreme heat, especially during heatwaves, increases the risk of heat-related illness.
- Dehydration: Not drinking enough fluids reduces the body’s ability to regulate its temperature.
- Physical exertion: Strenuous exercise or heavy work in hot weather increases body heat.
- Age: Infants, older adults, and people with certain health conditions have a higher risk.
- Medications: Some medicines can affect sweating, hydration, or the body’s ability to regulate heat.
- Clothing: Heavy, tight, or non-breathable clothing can restrict heat loss and increase body temperature.
Recognising heat stroke symptoms early is essential for seeking immediate medical care.
How to prevent heat stroke
Preventing heat stroke requires limiting heat exposure, staying hydrated, and allowing the body to cool regularly. Follow these steps:
- Step 1: Stay hydrated
Drink around 2–3 litres of water per day, unless a healthcare professional has advised you to restrict fluids. - Step 2: Plan outdoor activities
Schedule exercise or outdoor work before 9 AM or after 5 PM to reduce exposure to peak daytime heat. - Step 3: Protect your skin
Apply SPF 15 or higher sunscreen when spending time outdoors. Reapply as directed on the product label. - Step 4: Wear suitable clothing
Choose loose-fitting, lightweight, breathable clothing and wear a wide-brimmed hat when outdoors. - Step 5: Take regular cooling breaks
Rest frequently in shaded, cool, or air-conditioned areas during physical activity. - Step 6: Avoid overexertion
Reduce strenuous activity during extreme heat and increase activity gradually when adapting to hot conditions. - Step 7: Check on vulnerable people
Regularly check children, older adults, and people with certain medical conditions during periods of extreme heat.
What are the potential complications of heatstroke?
Untreated heat stroke can cause serious complications because extreme body temperatures can damage vital organs and affect normal brain function. Possible complications include:
- Organ damage: Severe overheating can damage the brain, heart, kidneys, liver, and muscles.
- Neurological problems: Heat stroke can cause confusion, seizures, loss of consciousness, or coma.
- Kidney failure: Severe heat-related dehydration and muscle damage can impair kidney function.
- Death: Heat stroke can be fatal if emergency treatment is delayed.

I opted for the Health Infinity plan for my parents. The digital onboarding was incredibly fast with no medical tests required since they are under 50. We had a minor daycare procedure last month, and the cashless approval came through in less than 2 hours. Very impressed with the efficiency.

The Bajaj Finance Health app is a lifesaver. I use it for my regular OPD consultations and medicine orders. The 10% discount on pharmacy bills and the easy reimbursement for doctor visits make it much more than just a 'hospitalization' policy. It’s daily health support.

Switched my family floater to Bajaj General this year. The network of hospitals in my city (Pune) is excellent. The only downside was a slight delay in getting my physical card, but the digital copy on the app works everywhere. The 'Wellness Rewards' for hitting step goals is a cool touch!
How long does it take to recover from heat stroke?
Recovery from heat stroke varies based on its severity and the extent of organ damage. Mild cases can improve after prompt cooling and medical treatment. Severe heat stroke may require hospitalisation and a longer recovery period. Some people can experience weakness, fatigue, or difficulty concentrating for days or weeks. Follow-up medical care may be needed to monitor kidney, liver, heart, or neurological complications. Avoid strenuous activity and extreme heat until a healthcare professional confirms that it is safe to resume normal activities.
Importance of keeping the body hydrated
Staying hydrated helps the body regulate temperature and maintain normal sweating during hot weather. Fluid loss through sweating can reduce the body’s ability to cool itself, increasing the risk of heat-related illness. Drink water regularly throughout the day, especially during outdoor activities or exercise. During prolonged or intense activity, electrolyte-containing drinks can help replace electrolytes lost through sweating. Avoid relying on thirst alone, particularly during prolonged exposure to high temperatures.
