1. The Severe Health Impacts of Air Conditioning
Prolonged heatwaves are currently occurring extensively. At this moment, air conditioners serve as a lifesaver for humans. However, not everyone knows its detrimental effects.

Sitting for extended periods in air-conditioned rooms, especially office workers, can lead to dry and even peeling skin. Additionally, your hair may become dry and brittle as air conditioners remove moisture from it during the cooling process.
Air conditioning is a leading cause of spreading infectious diseases
Air conditioners, when not cleaned regularly, tend to accumulate dust and mold, which then circulate around the room. This not only exacerbates severe allergies but also leads to various respiratory issues. Air conditioners also facilitate the spread of other infectious diseases through the air, infecting multiple people at once.
Aggravating Chronic Illnesses
If you have a chronic illness, it becomes even more severe when sitting in an air-conditioned room. This is because sitting under an air conditioner tends to worsen symptoms such as low blood pressure and joint inflammation. It also makes it difficult to control pain.
Immune System Erosion
Continuously subjecting the body to sudden temperature changes will quickly erode the body's immune system. This makes you more susceptible to illness, colds, and other diseases.
Sinusitis
Experts indicate that individuals sitting in air-conditioned environments for more than 4 hours are highly likely to develop sinusitis due to the cold air hardening nasal secretions.
Excessive Air Conditioning May Lead to Eye Inflammation
People sitting in air-conditioned rooms are prone to eye diseases such as eyelid inflammation and conjunctivitis. Additionally, those who wear contact lenses are susceptible to various other issues.
Headaches, Fatigue
When the air conditioning is set to a low temperature, it can cause a significant temperature difference between the body's internal temperature and the external environment, leading to overexertion and continuous headaches and fatigue.
Viral Infections
Air-conditioned environments, along with closed room doors, hinder the circulation of fresh air, instead promoting forced air circulation by air conditioners, creating favorable conditions for viruses to spread from one person to another.
Proper Usage of Air Conditioning
• Use air conditioning properly by avoiding setting the temperature too low. Many users tend to turn on the air conditioner, set the temperature very low to quickly cool the room, then turn it off and wait until the room gets warm again before turning it back on. This misuse not only damages the machine but also causes excessive energy consumption. Therefore, set the air conditioning temperature at 25 degrees Celsius or above to ensure both health and energy savings.
• Avoid tightly sealing air-conditioned rooms. Many people believe that keeping the room tightly sealed will prevent cold air from escaping and save energy. However, it's better to seal the door when the air conditioner is running. Before and after turning on the air conditioner, allow some time for air circulation by opening the room door.
• Use additional electric fans. Using additional fans helps improve air circulation in the room and provides a cooler sensation.
• Avoid using air conditioning all day. It's not advisable to keep the air conditioner running 24/7, as it's not good for your health. Instead, turn off the air conditioner and go outside during the cooler parts of the day.
