Excessive Heat: Hidden Health Dangers You Should Never Ignore
Summary
As summer weather continues to warm up, our risks of being affected by excessive heat increase. Many people underestimate how dangerous prolonged exposure to high temperatures can be. It is possible to suffer from dehydration or heat-related problems such as heat stroke, and those problems can be serious, even life-threatening. That is why it is very important to understand the potential dangers of excessive heat and the steps we can take to stay healthy on extremely hot days. In this blog, we will discuss the dangerous effects of excessive heat.
What is an Excessive Heat?
Excessive heat refers to the temperatures that are extremely elevated and deviate from what is normal for that region and time of year. The phenomenon of excessive heat typically occurs during extreme weather patterns called heatwaves, where temperatures are constantly above normal for an extended period of time (days, weeks).
If temperatures reach or exceed 40 °C (104°F) or if there is a combination of high temperatures and high humidity, the body has an increased risk of being unable to cool itself naturally. In these situations, there is a much greater chance that merely sweating will not be adequate to regulate the body’s temperature, thereby increasing the chance that you will develop heat-related illness. When temperatures and humidity soar to Peril levels, excessive heat warnings are issued. These alerts are especially critical for children, the elderly, and those with pre-existing health issues, as they face the greatest risk.
According to Dr. Swati Kapoor, Senior Internal Medicine Doctor at Miracles Healthcare, Gurgaon, prolonged exposure to extreme heat can stress the body and cause conditions like dehydration, heat exhaustion, or heat stroke. She also advises staying well hydrated, avoiding direct sun during peak hours, as well as recognizing early signs of heat-related problems.
Dr. Swati Kapoor has been working with patients for over 6 years to provide care for various types of illnesses. She specializes in the treatment of a variety of conditions, including diabetes, thyroid problems, high blood pressure, lung disease, and infectious diseases. She is committed to providing accurate diagnosis and results-oriented treatment for all her patients to aid them in their recovery and to promote optimal health outcomes.
Why Excessive Heat is Dangerous
In a normal situation, your body keeps itself at an internal temperature of 37 degrees Celsius (98.6 degrees Fahrenheit). In response to extreme hot temperatures, the body attempts to regulate its internal temperature by sweating and increasing the flow of blood (i.e., heat) to the skin.
However, if the temperatures are too hot or the body has been in contact with extreme heat for too long, your body's cooling mechanism may not function properly. This could result in an abrupt increase in body temperature, which can lead to major health problems.
Without proper hydration and cooling, heat stress or too much heat can damage your brain, heart, kidneys, and muscles.
Common Health Problems Caused by Excessive Heat
1. Dehydration
Dehydration happens when your body loses more fluids than it takes in. Excessive sweating during hot weather can lead to a fast loss of water and electrolytes.
Common symptoms include

3. Heat Stroke
Heat stroke is one of the most severe forms of heat-related illness and requires immediate medical attention. It occurs when the body temperature rises above 40°C (104°F), as well as the body loses its ability to cool itself.
Symptoms include
-
High body temperature.
-
Hot and dry skin.

Confusion or disorientation.

Rapid heartbeat.

Seizures or loss of consciousness.
Heat stroke can damage vital organs and can be fatal if not treated quickly.

Legs
