Heat exhaustion and heat stroke are serious heat-related illnesses that can occur when the body overheats due to prolonged exposure to high temperatures and/or physical exertion. It's crucial to recognize the symptoms and take preventive measures to avoid these potentially life-threatening conditions.
Despite being a lesser type of heat-related disease, heat exhaustion can develop into heat stroke if addressed. It usually happens when the body sweats too much and loses too much salt and water.
Symptoms of Heat Exhaustion:
Heavy sweating
Weakness or fatigue
Dizziness or lightheadedness
Nausea or vomiting
Headache
Muscle cramps
Cool, clammy skin
Rapid, weak pulse
Fainting or near-fainting spells
How to Treat Heat Exhaustion:
If someone is experiencing heat exhaustion, take the following steps:
Transfer the individual to a cool, shaded area.
Have them lie down and elevate their legs slightly.
Remove excessive clothing.
Provide cool, non-alcoholic beverages for hydration (water is best).
Use cool, damp cloths to help lower body temperature.
Be sure to visit a doctor if your symptoms linger or get worse.
Heat Stroke:
Heat stroke is a severe and life-threatening condition that occurs when the body's core temperature rises dangerously high, typically above 104°F (40°C). Due to the potential for organ failure or injury, it needs to be treated medically right away.
Symptoms of Heat Stroke:
High body temperature (above 104°F or 40°C)
Altered mental state, confusion, agitation, or even coma.
Rapid, shallow breathing
Rapid and strong pulse
Dry, hot, and flushed skin (no sweating)
Throbbing headache
Nausea or vomiting
Seizures
How to Treat Heat Stroke:
Heat stroke is a medical emergency, so if you suspect someone has it, take the following steps:
Call emergency services immediately.
Transfer the individual to a cool, shaded area.
Remove excessive clothing.
Try to cool the person down rapidly, such as by immersing them in a cool bath or shower or using cool water-soaked cloths. Do not use ice water, as it can constrict blood vessels and reduce cooling.
Fan the person to help with evaporation.
Don't offer the person any drinks.
Preventive Measures:
To prevent heat-related illnesses, follow these tips:
Stay hydrated: Drink plenty of water throughout the day, especially in hot weather or when engaging in physical activities.
Limit outdoor activities: Avoid strenuous activities during the hottest parts of the day, typically from late morning to early evening.
Dress appropriately: Wear lightweight, loose-fitting, and light-colored clothing in hot weather.
Seek shade: Take regular breaks in shaded areas if you're spending time outdoors.
Use sunscreen: Apply sunscreen with a high SPF to protect your skin from sunburn, which can impair the body's ability to cool itself.
Acclimatize: Gradually get used to the heat if you are not accustomed to it.
Never leave anyone in a parked vehicle, as temperatures can rise to dangerous levels quickly.
Remember, heat-related illnesses can be serious, so it's essential to recognize the symptoms and take appropriate actions to prevent them. If you or someone else is experiencing severe symptoms or if there's any doubt, seek medical attention promptly.
