Exercise During a Heat Wave

Are you telling yourself it’s too hot to exercise during a heatwave? As temperatures rise, adapting your fitness routine to the scorching summer conditions is important. The lazy days of summer can lead to reduced levels of activity and further complications down the road. Exercising during a heat wave requires extra caution and mindful strategies to stay safe. In this article, we’ll explore valuable tips to maintain an active lifestyle in high temperatures.  

First, Understand the Risks

Before discussing exercising in the heat, we must first understand the risks involved. Generally speaking, when the heat index is over 90 degrees, you should use caution when exercising outdoors. When it’s too hot the risk of heat-related illness like heat exhaustion and heatstroke can be life-threatening. While exercising outdoors in warmer weather can be safe, you should be well-versed in the dangers and how to avoid them.

1. Heat Exhaustion:

Heat exhaustion is the body’s response to an excessive loss of water and salt, usually through excessive sweating, and is most likely to affect the elderly and those who work in a hot environment. The symptoms of heat exhaustion should not be ignored as the condition can quickly progress to heatstroke. Symptoms of heat exhaustion include:
 
  • Headache
  • Nausea
  • Dizziness
  • Weakness
  • Irritability
  • Thirst
  • Heavy Sweating
  • Elevated Body Temperature

2. Heatstroke:

Heatstroke is the most serious heat-related illness. It occurs when the body can no longer control its temperature and is unable to cool down. Heatstroke can cause permanent disability or death if the person does not receive emergency medical treatment. Symptoms of Heatstroke include:

  • Confusion, altered mental status, slurred speech
  • Loss of consciousness 
  • Hot, dry skin or profuse sweating
  • Seizures
  • Very high body temperature

Since the dangers of heat-related illness can be life-threatening its important to pay attention to your body. If you or someone you know is experiencing symptoms of a heat related illness, stop what you’re doing and Call 911 Emergency Medical Services. Move away from direct heat if possible or to an air-conditioned room. Use water to cool the skin and apply wet cloths to aid in rapid cooling. Continue monitoring levels of consciousness until Emergency Medical Services arrive.

 

Staying Hydrated During a Heat Wave

Strategies for Beating the Heat

Now that we’ve discussed the dangers of exercising in the heat, we’ll cover strategies to help mitigate the risks. Since our bodies are consist of about 60% water, its important to maintain hydration before, during and after your workout. Drinking water does more than just quench your thirst. It’s essential to keeping your body functioning properly and feeling healthy.

1. Stay Hydrated

In general, adults loose about 9-12 cups of water per day through breathing, perspiration, urination, and bowel movements. If you plan on exercising while it’s warm, you’ll need to consume even more water to compensate for additional water loss as your body thermoregulates in the heat. Water helps maintain the body temperature, protect organs and tissues, lubricate joints, carry oxygen to cells, and break down minerals and nutrients making them accessible to your body. One of the best ways to avoid dehydration is hydrate before your workout, during and after your workout. If you wait until you’re feeling the symptoms of dehydration, it may be too late. 

+ Signs of Dehydration:

The easiest way to understand your hydration level is by looking at the color of your urine. If you are light in color, you are generally well-hydrated. If your urine color is towards the darker end of the scale, be sure to supplement your intake with fluids and monitor the color over the next few hours. Continued signs of dehydration, even after consuming fluids, may be an indication of a serious condition. Contact your nearest medical provider to avoid further complications.

2. Get Your Workout in Early

Plan your exercise during the cooler parts of the day, typically early in the morning or late evening. You should avoid exercising during peak heat hours when the sun is at its strongest, usually between 10am – 4pm. By choosing the right time, you can minimize exposure and the risk of overheating. 

3. Adjust the Intensity

If you’re an active person, you may already understand how the heat can negatively affect your energy and endurance levels. When temperatures are above normal, we recommend considering a less-vigorous workout that allows your body to continue working without overexerting.  This is a great opportunity to focus on your technique and body mechanics to help optimize your efforts.

4. Go Indoors

Just because it’s hot outside doesn’t mean your routine needs to suffer. Most commercial gyms or community centers have drop-in classes or trial memberships that you can attend with plenty of air-conditioned space. If you don’t have access to a gym, visit a shopping mall and park farther from the entrance. Choose the stairs instead of the escalator. The point is that exercise doesn’t have to be a formal setting. By making mindful choices, you can incorporate active habits and exercise in your daily routine. 

5. Dress Smart

If you decide to exercise outdoors, we recommend dressing for the occasion. Choosing lightweight, breathable, and moisture-wicking clothing that allows sweat to evaporate will help keep you cool during your workout. Wearing a hat and sunglasses also provides an additional layer of protection from the sun on those sweltering days. 

In Conclusion: Use it or Lose it

Don’t let the heat of the summer allow your level of fitness to slump. Without a regular dose of exercise, the body will decondition naturally. Often times, cardiovascular fitness is reduced first, followed by muscular strength. As people become less fit and activity becomes more challenging, they do less, leading to further down the vicious cycle of deconditioning. Deconditioning can also lead to weakness, more aches and pains, illness, and disease. It only takes two weeks without exercise to have a significant loss of cardiovascular fitness. Two to eight months of deconditioning can virtually erase all of your previous training effort.
