Sunstroke: Symptoms, Causes, Prevention & Treatment Guide
Protect yourself from sunstroke with this essential guide. Explore the symptoms, causes, and prevention tips.
What Is Sunstroke?
Sunstroke, also known as heat stroke, is a serious condition potentially caused by prolonged sun exposure, which could result in the body’s temperature rising to dangerous levels. Unlike heat exhaustion, sunstroke is more severe and often requires immediate medical attention.
Difference Between Heat Stroke and Sunstroke: While sometimes used interchangeably, heat stroke refers broadly to overheating due to any cause, while sunstroke specifically results from direct exposure to the sun.

Sunstroke Causes
Several factors contribute to sunstroke, with prolonged sun exposure being the most common. Here are different factors that can increase the risk:
1
Extended Time in Direct Sunlight
Being outdoors for prolonged periods of time without shade raises body temperature dangerously.
2
Dehydration
Inadequate fluid intake reduces the body’s ability to cool down through sweating.
3
Strenuous Physical Activity
Exercising or working outdoors in hot weather without breaks or proper hydration accelerates overheating.
4
Environmental Factors
Reflective surfaces like water, sand, and concrete amplify the sun’s intensity, increasing heat absorption.
5
High-Risk Individuals
Babies, young children, the elderly, and those with chronic conditions such as heart disease or diabetes are more vulnerable.

Facts Overview
What to Do About Sunstroke
How Do You Treat Heat Stroke?
1
Move to a Cooler Location
Find shade, enter an air-conditioned space, or use a fan to help cool the body.
2
Lower Body Temperature
Apply cool, damp cloths, take a lukewarm shower, or use cold packs on the neck, armpits, and groin.
3
Rehydrate
Sip water or electrolyte drinks to restore fluid balance, but avoid sugary, alcoholic, or caffeinated beverages, as they can worsen dehydration.
4
Monitor Condition
If symptoms persist or worsen, seek immediate medical attention. Loss of consciousness, seizures, or continued high fever are signs of a medical emergency.
Sunstroke: How Long Does It Last?
The duration of sunstroke recovery depends on its severity. Mild cases may resolve within a few hours with proper rest and hydration, while more serious cases can take days or even require hospitalisation for intravenous fluids and medical supervision. Be sure to seek medical attention if you are worried about any symptoms.
How to Prevent Sunstroke
Prevention is key to avoiding sunstroke. Follow these tips:
1
Stay Hydrated
Drink plenty of water throughout the day, even if you do not feel thirsty, to prevent dehydration.
2
Avoid Peak Sun Hours
Minimise direct sun exposure between 10 a.m. and 4 p.m., when UV rays are strongest.
3
Wear Appropriate Clothing
Opt for lightweight, loose-fitting, and light-coloured clothing. Wide-brimmed hats and UV-blocking sunglasses provide additional protection.
4
Take Regular Breaks
If spending extended time outdoors, rest in shaded or air-conditioned areas to allow your body to cool down.
5
Recognise Early Signs of Sunstroke
Dizziness, excessive thirst, or unusual fatigue should not be ignored—take immediate action to cool down.
Who Is More Prone to Sunstroke?
Certain individuals are at higher risk of sunstroke due to factors such as genetics, health conditions, and lifestyle. Key risk groups include:
1
Fair-Skinned Individuals
Lower melanin levels provide less natural protection against UV rays, increasing susceptibility to sun damage and overheating.
2
People with Medical Conditions
Chronic illnesses like heart disease, diabetes, or respiratory disorders can impair the body’s ability to regulate temperature.
3
Those Taking Certain Medications
Diuretics, antihistamines, and some blood pressure medications can increase dehydration and heat sensitivity. Be sure to consult your doctor if you use any of these medications.
4
Young Children and Older Adults
Infants and seniors have less efficient temperature regulation, making them more vulnerable to heat-related illnesses.
5
Athletes and Outdoor Workers
While regular exercise improves heat tolerance, excessive physical activity in high temperatures without adequate hydration raises the risk of overheating.
6
Dehydrated Individuals
Inadequate fluid intake reduces the body’s ability to cool itself through sweating, accelerating the onset of sunstroke.
