Although it is an important ally in thermal comfort, air conditioning can, in some situations, cause headaches. This happens due to different factors that involve incorrect use of the device or lack of proper maintenance. Below, see the main reasons that explain this discomfort and how to avoid it.
1. Dry air
One of the main causes of headaches when using air conditioning is dryness in the environment. The device reduces the humidity in the air, which can lead to mild dehydration and dryness of the respiratory tract, eyes and skin. This increases the feeling of tiredness and can cause headaches, especially in sensitive people.
How to avoid:
Use an air humidifier or leave a wet towel or a bowl of water in the room. Drinking plenty of water throughout the day also helps.
2. Poor air quality
Dirty or poorly cleaned filters accumulate dust, fungi and bacteria, which are released into the environment when the device is on. Inhaling these particles can cause irritation, allergic reactions, nasal congestion and frequent headaches.
How to avoid:
Clean the filters regularly, every 15 days, and perform complete maintenance on the device according to the manufacturer's recommendations.
3. Very low temperature
Air-conditioned environments with very cold temperatures cause blood vessels to contract, especially in the head and neck, which can lead to pain. In addition, prolonged exposure to cold can cause muscle tension, another factor that triggers headaches.
How to avoid:
Adjust the device to a comfortable temperature, between 23°C and 25°C, and avoid direct air currents on the body, especially the head and shoulders.
4. Noise and vibrations
If the air conditioner is making excessive noise or vibrations, it can cause sensory discomfort that, over time, can lead to headaches. This is more common in older models or those with loose parts.
How to avoid it:
Call a technician to check the unit, make adjustments and eliminate the noise. A well-installed and well-maintained unit should be quiet.
5. Poor ventilation of the room
Prolonged use of the air conditioner indoors, without air renewal, can increase the concentration of carbon dioxide (CO₂). This reduces oxygenation in the brain and causes fatigue, dizziness and headaches.
How to avoid it:
Ensure adequate ventilation by opening doors or windows periodically, or install systems that renew the air in the room.
Conclusion
Headaches caused by air conditioning are not normal and can be avoided with some simple precautions. Keeping the unit clean, adjusting the temperature correctly, taking care of humidity and ensuring ventilation of the room are fundamental measures to ensure comfort and well-being. If the problem persists, it is worth consulting a doctor to investigate other causes.
