The world is experiencing a severe heatwave, with temperatures reaching as high as 50 degrees Celsius. UN Secretary-General Antonio Guterres warns of an "extreme heat epidemic" due to climate change.
In such extreme heat, air conditioners (AC) have become a necessity for relief and comfort.
However, AC removes moisture from the air, leading to dryness, itching, and discomfort in the eyes.
Cool temperatures can lower metabolic rates, causing fatigue. Dry air can cause rapid moisture loss, leading to dehydration if fluids aren't replenished.
Low humidity can cause skin dryness and irritation. Cold, dry air can also irritate airways, worsening conditions like asthma and allergies.
AC systems can harbour allergens like dust, triggering allergic reactions. The constant humming can disrupt sleep patterns.
Dr Vidya Vimal advises regulating AC temperature to 25-27°C and avoiding direct cold air exposure for newborns. Frequent cleaning of ACs can prevent dust allergies.
Poorly maintained AC systems can spread bacteria, viruses, and fungi, increasing the risk of infectious diseases.
