Sun stroke:
Symptoms, causes, prevention & treatment guide
What is
sun stroke?
Sun stroke, 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, sun stroke is more severe and often requires immediate medical attention.
Difference between heat stroke and sun stroke: While sometimes used interchangeably, heat stroke refers broadly to overheating due to any cause, while sun stroke specifically results from direct exposure to the sun.
Sun stroke
causes
Several factors contribute to sun stroke, with prolonged sun exposure being the most common. Here are different factors that can increase the risk:
- Extended time in direct sunlightBeing outdoors for prolonged periods of time without shade raises body temperature dangerously.
- DehydrationInadequate fluid intake reduces the body's ability to cool down through sweating.
- Strenuous physical activityExercising or working outdoors in hot weather without breaks or proper hydration accelerates overheating.
- Environmental factorsReflective surfaces like water, sand, and concrete amplify the sun's intensity, increasing heat absorption.
- High-risk individualsBabies, young children, the elderly, and those with chronic conditions such as heart disease or diabetes are more vulnerable.

symptoms
Facts overview
What is sun stroke: It occurs when there is prolonged exposure to the sun and the body temperature rises abnormally.
Main causes: Dehydration is a key factor that accelerates the onset of heat stroke, impairing the body's ability to cool down. Direct, long-term sun exposure also significantly increases the risk by overwhelming the body's natural cooling mechanisms.
High-risk groups: Fair-skinned individuals, young children, the elderly, and those with medical conditions.
Prevention is key: Staying hydrated, using sun cream, and avoiding direct sun exposure during peak hours are crucial.
How do you treat
heat stroke?
- Move to a cooler locationFind shade, enter an air-conditioned space, or use a fan to help cool the body.
- Lower body temperatureApply cool, damp cloths, take a lukewarm shower, or use cold packs on the neck, armpits, and groin.
- RehydrateSip water or electrolyte drinks to restore fluid balance, but avoid sugary, alcoholic, or caffeinated beverages, as they can worsen dehydration.
- Monitor conditionIf symptoms persist or worsen, seek immediate medical attention. Loss of consciousness, seizures, or continued high fever are signs of a medical emergency.

How to
prevent sun stroke
- Stay hydratedDrink plenty of water throughout the day, even if you do not feel thirsty, to prevent dehydration.
- Avoid peak sun hoursMinimise direct sun exposure between 10 a.m. and 4 p.m., when UV rays are strongest.
- Wear appropriate clothingOpt for lightweight, loose-fitting, and light-coloured clothing. Wide-brimmed hats and UV-blocking sunglasses provide additional protection.
- Take regular breaksIf spending extended time outdoors, rest in shaded or air-conditioned areas to allow your body to cool down.
- Recognise early signs of sun strokeDizziness, excessive thirst, or unusual fatigue should not be ignored—take immediate action to cool down.
Who is
more prone to sun stroke?
- Fair-skinned individualsLower melanin levels provide less natural protection against UV rays, increasing susceptibility to sun damage and overheating.
- People with medical conditionsChronic illnesses like heart disease, diabetes, or respiratory disorders can impair the body's ability to regulate temperature.
- Those taking certain medicationsDiuretics, 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.
- Young children and older adultsInfants and seniors have less efficient temperature regulation, making them more vulnerable to heat-related illnesses.
- Athletes and outdoor workersWhile regular exercise improves heat tolerance, excessive physical activity in high temperatures without adequate hydration raises the risk of overheating.
- Dehydrated individualsInadequate fluid intake reduces the body's ability to cool itself through sweating, accelerating the onset of sun stroke.
By recognising these risk factors, individuals can take proactive steps to Protect themselves from extreme heat and sun exposure.
