How to Avoid Heat-Related Health Complications This Summer

Did you know that the CDC reports nearly 700 Americans die each summer from extreme heat? Higher outdoor temperatures can lead to hyperthermia (high body temperature), ultimately resulting in complications. It's August, and we are getting closer to fall. However, summer is not over yet. 

Prolonged heat exposure in the summer months can cause heat stroke and dehydration. What's more, extreme heat can worsen certain health concerns, including heart problems. Complications and illnesses due to heat are preventable. 

Here we explain why high summer temperatures are concerning and what precautions you should take this summer. 

Extreme Heat Worsen Heart Problems

Intense heat presents a health risk for everyone, especially those with heart conditions. They face danger and even an increased risk of death. That is because the way that our bodies adjust to heat can cause internal stress and even restrict blood flow. Also, blood pressure can increase when the body tries to cool itself, which strains vessels and the heart.

If you have ever had a stroke or a heart attack, your body may not be strong enough to compensate for the strain caused by extreme heat. If you start to feel sick or extremely uncomfortable from the heat, it could be a sign that something is going on. So, you should take action to calm and cool the body. 

Here are a few ways to help your body manage the stress of extreme temperatures this summer.


Prevention Tip 1: Stay Hydrated

During the summer, you must stay hydrated. Taking in enough fluids each day is essential to avoiding heat-related complications. Unless your doctor restricts your fluid intake because of heart or kidney disease, you should drink plenty of water. Avoid caffeinated beverages. Also, eat fruits that are high in water content, such as:

  • Watermelon
  • Strawberries
  • Mangoes
  • Peaches
  • Blueberries

Fruits also contain fiber, which can help balance your body's hydration.

Note: If your doctor has limited your water intake, ask how much you should drink this summer.


Prevention Tip 2: Avoid Sugary and Very Cold Drinks

This summer, avoiding sugary drinks like soda and juices would be best because they may increase the risks of high blood pressure, obesity and diabetes. They can also lead to a "sugar crash," which can drain your energy and harm your teeth. 


Prevention Tip 3: Maintain Electrolyte Levels

Salts and other minerals in the body are essential for vital body functions, including:

  • balancing hydration and pH level
  • transporting oxygen and chemicals to the tissues
  • send muscle and nerve signals 

Heavy sweating during the summer results in loss of electrolytes, like salts and minerals. It is best to replenish electrolytes during this season through a balanced diet. Consider adding a multivitamin to your diet to stay healthy so that you will be able to avoid heat-related health complications this summer.


Prevention Tip 4: Wear Appropriate Clothes

If you are going to be outside during the summer, experts recommend wearing loose-fitting, lightweight, and light-colored clothes. Light color clothes absorb less heat and may reflect the sun's rays compared to dark colors and heavy clothes.


Prevention Tip 5: Stay Indoors

In extreme heat, it is best to stay indoors in air-conditioned places. If you do not have air-conditioning at home, you could go to a public place like the library. Resting in air-conditioned buildings for part of the day will cool your body. Remember that fans can make you comfortable but may not prevent heat-related complications when the temperature is very high. 

If you don't have adequate air conditioning, you can also try to take a cool bath or shower. 

Avoid using your stove and oven as much as possible to keep your home cool.

If you must be outside, try to schedule outdoor activities during the coolest times of day, morning and evening hours. Rest in shady areas.


Prevention Tip 6: Use Sunblock

It is important to use sunblock because sunburn reduces your body's ability to cool down. It also makes you vulnerable to dehydration.

You may be able to prevent sunburn by wearing hats, sunglasses, and a broad-spectrum sunscreen outdoors. Try to apply SPF 15 or higher sunscreen 30 minutes before going outdoors.


Prevention Tip 7: Monitor People at High Risk

Although anyone can suffer from heat-related complications, some people are at higher risk. These may include: 

  • children
  • adults 65 years or older
  • people who are overweight
  • those suffering from heart diseases or high blood pressure

If you have loved ones at risk this summer, visit them or check on them frequently, especially during the day. Children and older adults may need extra help during summer.

Also, watch local news updates on extreme temperatures and safety precautions. 



If you or someone you know is not tolerating extreme heat this summer, here are some of the signs and symptoms you might notice. 

  • heart pounding
  • trouble getting enough air
  • feeling like they might faint
  • weakness
  • confusion

If you are with someone who complains of these heat-related symptoms, help them find a place to rest and cool off with a fan and a cold towel. Call a healthcare provider if the symptoms do not improve.
