Using Air Conditioning Effectively to Prevent Heat Wave Illness.

When the sweltering heat of summer arrives, one indispensable item in our lives becomes air conditioning and other cooling devices. Amidst the scorching heat, we often resort to frequent use of air conditioning to lower indoor temperatures. However, excessive use of these cooling devices can lead to a condition known as 'heat wave illness,' which can negatively affect our health. Though not classified as a specific disease, heat wave illness is a term encompassing various physical symptoms caused by abrupt environmental changes such as significant indoor-outdoor temperature differences and low humidity.

 

While air conditioning provides essential relief during hot summers, excessive use can be detrimental to health.

 

Causes and Symptoms of Heat Wave Illness

The primary causes include large temperature differences between indoor and outdoor environments and rapid decreases in humidity due to air conditioning. When the temperature difference between outside and indoors exceeds 10 degrees Celsius, our bodies struggle to adapt to these two environments, disrupting the balance of the autonomic nervous system and leading to a range of symptoms. Typical symptoms include fatigue, headaches, muscle aches, indigestion, and respiratory problems. In severe cases, it can even cause dizziness, vomiting, and diarrhea.

 

These symptoms are particularly pronounced in individuals with existing health conditions or weakened immune systems. For example, those with asthma or allergies are more susceptible to heat wave illness, and their symptoms can be more severe. Women, especially due to physiological reasons, may also be more affected by heat wave illness.

 

Prevention and Management of Heat Wave Illness

To prevent heat wave illness, it's crucial to minimize indoor-outdoor temperature differences. Experts recommend keeping the temperature difference within 5 degrees Celsius. Additionally, avoid setting indoor temperatures below 25 degrees Celsius and ensure appropriate indoor humidity levels. Air conditioners remove moisture from the air, potentially leading to a rapid drop in humidity. When humidity drops below 30-40%, respiratory mucous membranes can dry out, increasing susceptibility to respiratory diseases.

 

Adequate hydration is essential to prevent heat wave illness because dehydration can worsen symptoms by disrupting internal stability. Moreover, when using air conditioning for extended periods indoors, it's important not to expose your skin directly to cold air. Wearing lightweight long-sleeved clothing or stockings can help protect your skin from direct exposure to cold air.

 

Precautions for Using Air Conditioning During Sleep

Since heat wave illness can worsen during sleep, it's advisable to turn off air conditioning while sleeping. During sleep, the body's resistance to stressors decreases, potentially making excessive use of air conditioning detrimental to health. If continuous air conditioning is necessary, reducing the cooling intensity or using a timer to automatically turn it off after a set period is recommended.

 

Especially for women, it's important to avoid chilling the waist and lower abdomen during sleep. This not only helps prevent heat wave illness but also aids in preventing abdominal-related disorders. If you experience headaches or fatigue during sleep, it could be related to air conditioning use, so promptly turning it off and taking appropriate rest is crucial.

 

Tips for Preventing Heat Wave Illness Related to Diet

Diet also plays a crucial role in preventing heat wave illness. It's better to consume warm, nutritious foods rather than cold ones. Particularly, foods rich in plant-based oils can boost immune system function, aiding in the prevention of heat wave illness. While cold beverages and ice cream are tempting during summer, they can impair digestion and worsen symptoms of heat wave illness. Instead, drinking lukewarm water or warm tea regularly can help replenish fluids effectively.

 

When moving between air-conditioned indoors and hot outdoors, it's important to maintain body temperature to reduce stress caused by sudden temperature changes. When going out, wearing light outerwear to adjust body temperature upon entering indoor spaces or removing when going outdoors is essential.

 

Guide to Using Air Conditioning for a Healthy Summer

In conclusion, heat wave illness arises from excessive use of air conditioning during hot summers, causing bodily imbalances. To prevent this and have a healthy summer, it's important to learn proper use of air conditioning, minimize indoor-outdoor temperature differences, maintain adequate hydration, and practice balanced eating habits. Additionally, protecting your skin during prolonged stays in air-conditioned spaces and minimizing air conditioning use during sleep can effectively prevent heat wave illness.

 

While air conditioning provides essential relief during hot summers, excessive use can be detrimental to health. By adhering to precautions when using air conditioning and maintaining healthy lifestyle habits, you can prevent symptoms of heat wave illness and enjoy a healthier summer.
