Heat Illness in the Heat, An Unwelcome Summer Guest

Main Causes of Heat Illness

Heat illness is primarily caused by two main factors. The first cause is the temperature difference between indoors and outdoors. During the summer, the outside temperature often soars above 30 degrees Celsius, but indoors, air conditioning typically keeps the temperature around 20 degrees. Such extreme temperature differences stimulate the body's autonomic nervous system, making it difficult to regulate body temperature. When body temperature regulation is not smooth, various physical symptoms such as fatigue, headaches, and dizziness may occur. These symptoms can be more severe when suddenly moving from outside to inside, as the autonomic nervous system struggles to adapt to the rapid temperature change.

The second cause is the sudden drop in humidity. As air conditioners cool the air, they also reduce humidity, resulting in very dry indoor air. When humidity drops below 30%, the mucous membranes in the respiratory tract become dry, creating an environment that can lead to respiratory diseases. Dry air can also dry out the skin, leading to itching or skin troubles. Reduced humidity negatively affects overall health, especially for those sensitive to dry air who may suffer even more.

Symptoms and Impact of Heat Illness

Heat illness manifests in various symptoms, which can have significant effects. The most common symptoms are respiratory symptoms similar to a cold, such as nasal congestion, coughing, and sore throat. Additionally, headaches, dizziness, muscle aches, fatigue, and digestive issues like indigestion, abdominal pain, and diarrhea may occur. These symptoms go beyond mere discomfort, severely disrupting daily life. They can be particularly severe for individuals with weakened immune systems or chronic illnesses, potentially leading to the worsening of their conditions.

Heat illness is not just a source of discomfort; it can have long-term health impacts. For example, if the balance of the autonomic nervous system is continually disrupted, it can strain the heart, lungs, and nervous system, worsening chronic conditions. This can lead to chronic fatigue or a general decline in health. Moreover, if someone with heat illness is exposed to infectious diseases, their weakened immune system makes them more susceptible to illnesses such as colds or flu, and recovery may be slower.

Practical Measures to Prevent Heat Illness

The most important step in preventing heat illness is to minimize the temperature difference between indoors and outdoors. It's advisable to avoid setting the indoor temperature too low and to keep the difference with the outdoor temperature within 5 degrees Celsius. This allows the body to adapt to the temperature change smoothly, aiding in body temperature regulation. When using air conditioning, it's beneficial to use fan mode to circulate the air and to avoid concentrating cold air in one spot. It's especially important to avoid direct exposure to air conditioning drafts.

Maintaining humidity is also essential. To prevent indoor air from becoming too dry, use a humidifier or drink water frequently to keep your body hydrated. Placing bowls of water around the house or keeping indoor plants can also help maintain humidity levels. Proper indoor humidity helps protect respiratory health and prevents skin dryness, which is particularly effective in preventing respiratory diseases that occur in dry environments.
