Air conditioning provides a welcome escape from heat, but prolonged exposure can lead to uncomfortable symptoms often termed “AC sickness.” This common experience describes feeling unwell after spending time in air-conditioned environments. Understanding its typical symptoms and contributing environmental factors is helpful.
Understanding Air Conditioning Sickness
Air conditioning sickness refers to a range of mild but persistent symptoms experienced after extended exposure to air-conditioned spaces. Common complaints include dry eyes, a sore throat, nasal congestion, headaches, fatigue, dizziness, or dry, itchy skin. These symptoms are generally not severe.
This “sickness” is not a recognized medical condition. Instead, it represents a cluster of physical reactions linked to specific environmental conditions created by air conditioning systems. The discomfort often subsides once a person leaves the air-conditioned environment.
Contributing Factors
Several environmental and physiological factors contribute to air conditioning sickness. Air conditioning systems remove humidity from the air, creating a dry indoor environment. This low humidity can dehydrate mucous membranes in the nose and throat, leading to irritation, dryness, and increased susceptibility to minor infections. Dry air also affects the eyes, causing irritation and itchiness as tears evaporate more quickly.
Another factor is the physiological stress caused by significant temperature differences when moving between very cold air-conditioned spaces and hot outdoor environments. The body must constantly adjust to these rapid changes, which can lead to feelings of general discomfort and fatigue.
Poor indoor air quality within air-conditioned environments also plays a significant role. Air conditioning units can circulate dust, allergens, mold spores, and even bacteria if not properly maintained. Condensation within AC units can create damp conditions conducive to mold and mildew growth, which then become airborne. A lack of fresh air intake due to sealed, air-conditioned buildings can lead to the accumulation of stale air and indoor pollutants.
Improper maintenance of air conditioning systems exacerbates these issues. Dirty filters, clogged coils, and stagnant water in drain pans provide breeding grounds for microbes. When these systems operate, they can disperse these contaminants throughout the indoor space, contributing to respiratory issues and headaches.
Prevention and Relief Strategies
Maintaining proper hydration is a straightforward strategy to mitigate symptoms of air conditioning sickness. Drinking plenty of water throughout the day helps counteract the dehydrating effects of dry, air-conditioned air on the body’s mucous membranes and skin. Staying well-hydrated supports overall bodily functions and can alleviate dry eyes, throat irritation, and headaches.
Adjusting thermostat settings to a more moderate temperature can also provide relief. Avoiding excessively low temperatures reduces the physiological shock when transitioning between indoors and outdoors. A comfortable indoor temperature, typically between 72-76 degrees Fahrenheit (approximately 22-24 degrees Celsius), can minimize discomfort and prevent the air from becoming overly dry.
Utilizing humidifiers can reintroduce moisture into the air, counteracting the drying effect of air conditioning. This is particularly beneficial in bedrooms or offices where individuals spend extended periods. Adding humidity helps keep eyes, skin, and respiratory passages from drying out, reducing irritation and susceptibility to symptoms.
Regular maintenance of air conditioning units is essential for preventing the circulation of allergens and microbes. Cleaning or replacing air filters monthly during peak usage ensures efficient operation and cleaner air. Professional servicing of the AC system, including cleaning coils and drain pans, helps prevent mold and bacteria buildup.
Improving ventilation by occasionally opening windows or taking breaks outside can introduce fresh air and reduce the concentration of indoor pollutants. This practice helps to air out stagnant spaces, especially in environments where air is constantly recirculated. For personal relief, using eye drops can soothe dry and irritated eyes, while nasal sprays can alleviate nasal dryness and congestion. Moisturizers can also be applied to combat dry skin.
