We are dealing with continuous days of high heat, high dew point, and high humidity. For me, it sucks. Three of my medications make me more sensitive to heat and humidity. I step outside and the heat is oppressive to me and my body. My head starts pounding, I sweat almost immediately, and my skin feels like it is on fire. I recently learned that the dew point is a better predictor than humidity for the “feels like.”
Where the chart states getting uncomfortable, I am already miserable because of the side effects of my meds. I go out walk the dog and head back inside. We don’t stay out very long. If I am going to walk, I have to find a place inside to walk. I hate that and I usually won’t go and do it.
What could I do? I could begin lifting weights again. I could walk outside at times when it is less hot and humid. Or I can complain and sit on my butt until the weather is better. Right now it is a toss-up. Stay hydrated and listen to your body. Your body still needs to be moving.
Staying active is an essential part of a healthy lifestyle, but it can be challenging to maintain physical activity during hot and humid days. Engaging in physical activity in extreme heat can lead to various physiological issues such as heat exhaustion or heatstroke. Therefore, it is essential to understand how to exercise safely in hot weather.
The heat index measures how hot it feels outside when humidity is considered. Monitoring the heat index before engaging in any physical activity is crucial. If the heat index is above 90°F, it is recommended to slow down or avoid outdoor activities altogether. Staying inside and engaging in indoor activities such as yoga, Pilates, or strength training can be an excellent alternative to outdoor activities during hot and humid days.
Changing activities until it is cooler outside is another option to consider. For example, if you enjoy running, you could switch to swimming or indoor cycling during the hottest part of the day. By changing up your activities, you can still maintain your physical activity level while avoiding the risks associated with exercising in extreme heat.
Understanding Heat and Humidity
The Heat Index Explained
The heat index is a measure of how hot it feels when relative humidity is factored in with the actual air temperature. As humidity increases, the body’s ability to cool itself through sweating decreases, making it feel much hotter than the actual temperature. For example, on a day with a temperature of 90°F and a relative humidity of 70%, the heat index would be 105°F, making it feel much hotter and more uncomfortable than the actual temperature.
Physiological Impacts of Hot Weather
Prolonged exposure to hot and humid weather can have several physiological impacts on the body, including dehydration, heat exhaustion, and heat stroke. Dehydration occurs when the body loses more fluids than it takes in, which can lead to symptoms such as thirst, dry mouth, headache, and fatigue. Heat exhaustion is a more serious condition that can occur when the body is unable to cool itself properly, resulting in symptoms such as heavy sweating, dizziness, nausea, and muscle cramps. Heat stroke is the most severe form of heat-related illness and can be life-threatening if not treated promptly. Symptoms include a high body temperature, confusion, seizures, and loss of consciousness.
To avoid these physiological impacts, it is important to take precautions when exercising or being active in hot and humid weather. This can include staying hydrated by drinking plenty of water, taking breaks in the shade or indoors, wearing lightweight and breathable clothing, and avoiding outdoor activities during the hottest parts of the day. It is also important to listen to your body and slow down or stop if you start to feel unwell. By taking these precautions, you can stay safe and healthy while still getting your physical activity in during hot and humid days.
Planning Your Physical Activities
When it comes to physical activity during hot and humid days, planning is key. By choosing the right time of day and type of activity, you can stay safe and comfortable while still getting the exercise you need.
Choosing the Right Time of Day
It’s important to avoid exercising during the hottest parts of the day, typically between noon and 3 p.m. Instead, try to plan your physical activity for the early morning or late evening when the temperature is cooler. According to the American Heart Association, “Timing is key.”
When planning your physical activity, it’s also important to consider the heat index. The heat index takes into account both the temperature and humidity, which can make it feel much hotter than it actually is. If the heat index is high, it’s best to avoid outdoor activities altogether or choose a less strenuous activity.
Indoor vs. Outdoor Activities
On hot and humid days, indoor activities can be a great alternative to outdoor activities. Not only are they typically air-conditioned, but they also provide a change of scenery and can be a fun way to mix up your routine. Some indoor activities to consider include:
- Swimming or water aerobics
- Yoga or Pilates
- Dancing or Zumba
- Indoor rock climbing or bouldering
If you prefer outdoor activities, try to choose activities that are less strenuous and can be done in shaded areas. Walking, hiking, and biking are all great options, as long as you take breaks and stay hydrated.
By planning your physical activities carefully, you can stay safe and comfortable while still getting the exercise you need. Remember to listen to your body and adjust your routine as needed to stay safe and healthy.
Adapting Your Workout Routine
During hot and humid days, it’s crucial to adapt your workout routine to avoid heat exhaustion and other heat-related illnesses. Here are some tips for modifying your workout routine during hot weather:
