Does Air Cooler Cause Cold?

Air cooler

Air coolers, also known as evaporative coolers, work by using the natural process of evaporation to cool the air. They pull warm air through water-saturated pads, and as the air passes through these pads, the water evaporates, causing the air temperature to decrease. This cooled air is then circulated into the room.

Contrary to popular belief, air coolers themselves do not cause cold or directly contribute to causing illnesses like the common cold. The common cold is caused by viruses, not by a drop in temperature. However, if an air cooler is not properly maintained and cleaned, it can potentially harbor mold, bacteria, or allergens that, when circulated into the air, may cause respiratory issues or exacerbate existing conditions in sensitive individuals.

Additionally, the drop in humidity caused by the evaporation process in air coolers might dry out the air in the room. While this can provide relief in hot and humid climates, excessively dry air can potentially lead to dry skin, irritated nasal passages, or throat discomfort in some individuals.

To minimize any potential health issues related to air coolers:

  • Maintain cleanliness: Regularly clean and change the water in the cooler, clean the filters, and ensure proper ventilation to prevent the growth of mold or bacteria.
  • Monitor humidity levels: Keep an eye on the humidity levels in the room to ensure they’re not excessively low, which could cause discomfort.
  • Use it in moderation: Avoid prolonged exposure to direct air from the cooler, especially if it’s causing discomfort or dryness.

In summary, while air coolers themselves don’t cause colds, their improper maintenance or overly dry conditions might impact respiratory health or cause discomfort in some individuals. Proper cleaning and moderation in usage can help mitigate potential issues associated with air coolers.
