Preventing Heat-Related Illnesses as Temperatures Rise

As temperatures rise during the hotter months, it’s helpful to be aware of the risks heat-related illnesses can pose to your health.  Conditions like heatstroke, dehydration, and heat exhaustion can develop quickly and lead to serious consequences if not addressed quickly.  At our emergency room, we want to make sure you stay safe and healthy as the hot weather rolls in and continues to intensify.  We’re going to walk through a couple heat-related illnesses and give you some tips on how to protect yourself and your loved ones this summer. 

Understanding Heat-Related Illnesses

Before getting into prevention, it’s important to first realize heat-related illnesses and how they develop. 

• Heatstroke: This is the most severe heat-related illness that comes into play when your body’s temperature regulation system breaks down.  This then leads to a rapid increase in body temperature which can cause confusion, loss of consciousness, or even organ failure.  Heatstroke is a medical emergency that requires immediate treatment in the emergency room.
• Dehydration: Dehydration happens when your body loses more fluids than it takes in.  In hot weather like we get in Southeast Texas, you naturally sweat more, and if you don’t replace those lost fluids, dehydration can set in.  Early signs include thirst, dry mouth, dizziness, and dark colored urine.  Severe dehydration can end up leading to heat exhaustion or heatstroke, which requires urgent care in the emergency room. 
• Heat Exhaustion: Heat exhaustion happens when your body overheats but has not yet reached the dangerous levels seen in heatstroke.  It can lead to heavy sweating, weakness, dizziness, nausea, and headaches.  If heat exhaustion is not treated though, it can end up turning into heatstroke, a life-threatening emergency that needs attention in the emergency room. 

Tips for Preventing Heat-Related Illnesses

With these conditions in mind, here are a few steps you can take to reduce your risk and stay safe during the warmer months coming up:

Stay Hydrated

Making sure to stay hydrated is essential in hot weather like ours.  When you’re sweating more, it’s important to replace the fluids you’ve lost.  Remember to drink water consistently throughout the day, even if you don’t feel thirsty.  Additionally, try to avoid alcohol and caffeinated drinks, as they can lead to further dehydration.  If you’re participating in physical activities outdoors, think about drinking an electrolyte beverage to keep up a healthy balance of salts and minerals.

Wear Lightweight, Breathable Clothing

Try to wear clothes that are loose and made from breathable fabrics like cotton.  These materials help your body stay cool and make it easier for sweat to evaporate.  Another thing to keep in mind is dark clothing can trap heat and increase your risk of heat-related illnesses. 

Take Regular Breaks in the Shade

If you’re spending a good amount of time outdoors, take consistent breaks in a shaded area or an air-conditioned space to cool down.  This is especially important if you’re working or exercising in the heat.  Overexertion can quickly lead to heat exhaustion, and if you don’t take the necessary precautions, it could mean a visit to the emergency room. 

Avoid the Hottest Part of the Day

The most intense part of the day is generally between 10 a.m. and 4 p.m.  If it’s possible, try to schedule your outdoor activities for cooler parts of the day like early morning or late evening.  During the hottest times, try to stay indoors to prevent any unnecessary heat exposure. 

Use Sunscreen

Excessive sun exposure can lead to sunburn, which increases your body’s risk of overheating.  Always apply sunscreen with at least SPF 30 to any exposed skin before going outside, and then reapply every two hours or after swimming or sweating. 

Recognize the Signs of Heat-Related Illnesses

Understanding the warning signs of heat-related illnesses is essential to helping prevent them.  If you or someone around you is feeling dizzy, nauseous, confused, or even has a rapid heartbeat or fainting, look for shade immediately, hydrate, and cool the body with a damp cloth.  If symptoms get worse or you think it might be heatstroke, get to the emergency room as soon as possible. 

When to Seek Help at the Emergency Room

If heat-related symptoms start to get worse and the individual shows signs of confusion, loss of consciousness, a quick pulse, or hot and dry skin, this might point to a heatstroke, which requires immediate attention at the emergency room.  The quicker you act, the better chances of recovery. 

In the case of heat exhaustion or dehydration, if the symptoms do not get better with rest and rehydration, or if the person is not able to keep fluids down, it’s probably a good idea to seek professional medical care.  The emergency room is prepared to provide intravenous fluids and cooling methods for more severe cases. 

With the temperatures starting to warm up, taking steps to prevent any heat-related illnesses is an important part of staying healthy.  By hydrating, wearing smart clothing, and knowing when to get medical care, you can lessen your risk of heat exhaustion, dehydration, or heatstroke.  Always remember though, if you or someone you know is having extreme symptoms, don’t wait to visit the emergency room for quick treatment. 

Stay safe and enjoy the summer while keeping an eye on your health.  Your local emergency room is always here for you, ready to give you the care you need in case of heat-related emergencies.
