Heat stroke is a medical emergency, not just "too much sun." If someone stops sweating despite the heat, becomes confused, or loses consciousness, move them to shade, cool them with water, and call +91-8282 8989 18 immediately β heat stroke can be fatal within a short time if untreated.
Summers in Rajahmundry bring genuine risk of heat-related illness, and the line between "just tired from the heat" and a true emergency can be crossed quickly. Knowing the difference between dehydration, heat exhaustion, and heat stroke can save a life.
What this guide covers

Warning Signs of Heat Stroke
π« This is an emergency if you see
- Body feels very hot to touch, often with little or no sweating
- Confusion, slurred speech, or unusual behaviour
- Rapid heartbeat
- Dizziness, fainting, or loss of consciousness
- Nausea or vomiting
What to Do Immediately
β Do this
- Move the person to shade or a cool area right away.
- Remove excess clothing to help heat escape.
- Cool them with water β wet cloths on the skin, or gently pour cool water, while fanning them.
- If conscious and able to swallow, give small sips of water or ORS.
- Call +91-8282 8989 18 or 108 for suspected heat stroke β don't wait to see if they recover on their own.
What to Avoid
π« Don't do this
- Don't give fluids to someone who is confused or unconscious β risk of choking.
- Don't leave them alone while symptoms are present.
- Don't assume rest alone will fix it if confusion or very high body temperature is present β this needs medical treatment.
"Heat stroke can escalate within an hour if not treated. The moment someone stops sweating and starts acting confused in extreme heat, that's not a 'wait and see' situation β get them cooling down and get them to us."β Dr. Chaitanya Pilladi, Consultant Anaesthesiologist & Intensivist
When to Rush to Hospital
Any suspected heat stroke β confusion, very high body temperature, or loss of consciousness in the heat β needs immediate emergency care. Sri Ganga Hospital's emergency department is equipped 24Γ7 to manage heat-related emergencies.
What Happens When You Arrive at Sri Ganga
- Rapid cooling continues β active cooling measures continue with monitoring of core body temperature.
- IV fluids β given to correct dehydration and support circulation, adjusted based on the person's condition.
- Organ function checks β blood tests screen for effects on the kidneys, liver, and muscle that severe heat stroke can cause.
- Continuous monitoring β vital signs and temperature are tracked closely until the person is stable.
Who Is at Higher Risk of Heat Stroke
- Outdoor workers and laborers β prolonged heat exposure with limited breaks or hydration.
- Elderly people β the body's ability to regulate temperature declines with age.
- Young children β they overheat faster than adults and may not communicate distress clearly.
- People on certain medications β some blood pressure and psychiatric medications affect the body's ability to cool itself; check with your doctor if you're unsure.
Frequently Asked Questions
What is the difference between heat exhaustion and heat stroke?
Heat exhaustion causes heavy sweating, weakness, and dizziness, but the person is still sweating and alert. Heat stroke is more severe: body temperature rises dangerously high, sweating may stop, and the person can become confused or lose consciousness. Heat stroke is a medical emergency.
What should I do if someone shows signs of heat stroke?
Move them to shade or a cool area immediately, remove excess clothing, and cool them with water or wet cloths while fanning them. Call +91-8282 8989 18 or 108 right away, as heat stroke can be fatal without prompt treatment.
Should I use ice-cold water to cool someone with heat stroke?
Cool water and wet cloths with fanning are effective and safe. Avoid ice-cold immersion for very young children or elderly patients without medical guidance, as it can cause shivering that raises body temperature instead of lowering it.
Key takeaways
- Heat stroke is a true emergency β different from ordinary dehydration or heat exhaustion
- Confusion, lack of sweating, and very high body temperature are the red flags
- Move to shade, cool with water, call for help immediately
- Never give fluids to someone who is confused or unconscious
