3 Types of Heat-Related Illnesses You Should Know About

Last year, a man was said to have collapsed and died at one of the most popular tourist sites in the world, the Death Valley National Park, California. Reports suggested that his death may have been heat-related, given the notoriety of Death Valley as one of the hottest places on Earth. 

Indeed, heat can be dangerous to human health. However, it may interest you to know that you do not have to be at Death Valley or any of the remarkably hot places on the planet before your health can be affected by hot weather. As the challenge of climate change continues to grow, more people across the world are exposed to heat and heat-related illnesses and this trend has been predicted to keep rising. So, anywhere you are; if you can feel the heat, literally,  then you should know it can impact your health in various ways. 

Here are three notable heat-related illnesses you should be mindful of.

3 Types of Heat-Related Illnesses

Heat Stroke

Heat stroke is the most severe type of heat-related illness. It occurs when the environment is so hot that the body’s ability to regulate its temperature fails. It tends to occur more in children and older people as well as those who overwork themselves during hot weather. Heat stroke is a medical emergency and can be life-threatening if not immediately addressed.

Symptoms of heat stroke

• Very high fever (usually above 40⁰C)
• Red and dry skin
• Dizziness
• Fast pulse
• Headache
• Tiredness
• Confusion
• Nausea
• Vomiting
• Loss of consciousness

Heat Exhaustion

Heat exhaustion occurs when the body overheats and is unable to cool down. This leads to profuse sweating and excessive loss of water and salts from the body. Just like heat stroke, it is common in children and elderly people. However, regardless of your age, you are likely to experience heat exhaustion when you subject yourself to any activity that makes you sweat excessively without taking an adequate amount of fluids. If untreated, heat exhaustion can progress to heat stroke.

Symptoms of heat exhaustion

• Excessive sweating
• Fever
• Fast pulse
• Pale, moist and cold skin
• Headache
• Body weakness
• Nausea
• Vomiting
• Fainting
• Light-headedness
• Muscle cramps

Heat Cramps

Heat Cramps are mild forms of heat illnesses that involve painful, involuntary muscle spasms. They occur mostly among athletes who sweat a lot in hot and humid weather conditions. Excessive sweating deprives the muscles of the salt and water they need to function adequately, resulting in muscle cramps. 

Symptoms of heat cramps

• Painful cramps,  commonly in the arms, legs, back and sometimes abdomen.
• Red, moist skin
• Excessive sweating.

First Aid in Heat-Related Illnesses

Here are the important first-aid steps you should take in situations of heat-related injuries:

• Move to a cool place and rest; stop participating in the activity.
• Remove excess and tightly fitted clothing.
• Place cool or moist clothing on the skin; fan the skin.
• Give cool fluids containing salt and sugar, if able to drink.
• In cases of heat cramps, stretch cramped muscles slowly and gently.
• Remember that heat stroke is a medical emergency. So ensure that the victim is moved to the nearest hospital immediately. This also applies when the victim is unable to drink, or unresponsive to your first aid.

Preventing Heat-Related Illnesses

Here are general tips to help you navigate hot weather conditions and prevent heat-related illnesses

• Drink a lot of fluids on hot days and even more fluids while participating in vigorous activities. However, avoid alcohol and caffeine-containing drinks as these can get you dehydrated.
• Wear light-coloured, lightweight, and loose-fitting clothing on hot days.
• Schedule sports and other strenuous activities for mornings and evenings and take intermittent rests in between these activities.
• Spend as much time indoors as you can during hot and humid days.
• Use sunshades, umbrellas and sunscreens for protection from the sun. Read our previous post to lean more about how you can prevent sunburn.
• If you have a medical condition, speak with your doctor for expert advice on how you can prevent heat-related illnesses.

A Word from HealthFacts to You

Beyond mere discomfort, heat can affect your health in significant ways. So, in times when the weather is hot, ensure to stay well hydrated, wear proper clothing and as much as you can, schedule activities for appropriate times of the day.
