Summer Heat and Sunstroke: Warning Signs, First Aid, Prevention Tips
18 Aug 2026 Posted By Skinlogics
The summer season in India marks the hottest time of the year, when our health can deteriorate due to exposure to intense heat, high humidity, excessive sweating, and strong UV rays. Most people who spend their days outdoors in the summer experience mild, heat-related illnesses. But if they are having a sunstroke, that’s a medical emergency requiring immediate relief.
If sunstroke is left untreated, it can cause serious health complications that may even be fatal. Keeping this in mind, a dermatologist in Noida at Skinlogics Clinic discusses the causes, warning signs, and prevention strategies for sunstroke to help people understand when medical attention is needed.
What is Sunstroke?
Sunstroke, or heat stroke, is a medical condition in which the body is unable to cool itself through sweating due to prolonged exposure to extreme summer heat or strenuous physical activity in hot, humid weather.
Often, in a sunstroke, the body’s core temperature rises to 40°C (104 °F) or higher, and so the sufferer needs prompt medical attention.
Who is More Likely to Develop a Sunstroke?
Sunstroke is a problem that anyone can face. But certain individuals are at higher risk of having it, such as:
- Elderly people
- Dehydrated individuals
- Infants and small children
- Physical laborers who work out in the sun
- Fitness enthusiasts, sportspersons, or athletes
- Patients with some chronic health issue
- Individuals who take certain medications, including photosensitizing drugs.
Warning Signs Indicating a Sunstroke
Early identification of sunstroke can help sufferers get timely treatment before their condition becomes serious.
Here are the early, first signs of sunstroke, which is called heat exhaustion:
- Excessive perspiration
- Dizziness
- Weakness and fatigue
- Headache
- Nausea or vomiting
- Muscle cramps
- More thirst
- Clammy, cool skin.
If these signs are not timely identified and addressed, heat exhaustion can turn into a sunstroke- a medical emergency.
Here are the signs of sunstroke that call for immediate medical attention:
- Fever (40°C or 104 °F)
- Red, hot, or dry skin
- Slurred speech
- Confusion or disorientation
- Loss of consciousness
- Seizures
- Severe headache
- Lack of sweating
- Trouble breathing
- Rapid heartbeat.
First Aid for Sunstroke
Just as warning signs of sunstroke appear, getting the patient to a medical emergency ward may take some time.
Until then, the doctor recommends providing first aid to the person having sunstroke.
If the above-mentioned warning signs of sunstroke are being experienced by someone outdoors, where you are, do follow these steps:
- Immediately shift the person to a shaded, well-ventilated location, preferably indoors
- Call for emergency medical services to get the patient to a doctor
- While medical assistance arrives, remove the person’s extra clothes. Apply damp, cool clothes to the skin and even spray cool water all over the body. Keep the person under the fan. Also, apply ice packs on the groin, armpits, and neck regions to help rapidly cool the patient’s body
- If the person is conscious, make the person drink cool water and, if possible, give them oral rehydration solution. Do not force the person to drink water. Avoid giving alcohol, caffeinated drinks, and sugar-loaded beverages
- Continuously and closely monitor the person’s breathing, responsiveness, and level of consciousness. If breathing stops, give CPR if trained.
How to Avoid Getting a Sunstroke?
If you are most vulnerable to developing sunstroke, here are the recommended prevention tips from sunstroke that one must follow:
- Drink adequate water throughout the day. Increase fluid intake if spending more time outdoors in the sun. Don’t wait for yourself to feel thirsty
- Try to avoid unnecessary exposure to summer heat and strong UV rays from the sun during peak hours of the day (11 am to 4 pm)
- Wear loose-fitting, soft, light-colored, cotton clothes to keep your body cool by improving air circulation, if you have to go outdoors during the day
- Protect your face and body from direct sunlight by wearing a broad-spectrum sunscreen with SPF 30 or higher, a wide-brimmed hat, and sunglasses. Also, don’t forget to use an umbrella
- Take frequent breaks from vigorous physical activity, seek shade to rest and cool down. Do not overexert the body
- Consume plenty of water-rich foods such as cucumbers, oranges, watermelon, muskmelon, coconut water, and strawberries.
- Never sit for a long time in vehicles parked under the sun.
Final Thoughts
Summer heat can considerably impact your well-being if your body is not protected from it. It can lead to sunstroke, a dangerous medical condition, where the natural cooling mechanism of the body fails. Knowing the signs of heat exhaustion and sunstroke is essential to help someone with sunstroke get the necessary first aid and, best of all, medical help.
