It is time we realised that this equipment can harm our health and endanger the Earth.
How many of us realise that air conditioners are bad for human health? How many of us know that air conditioners harm the environment? A better question to ask – how many of us who know these truths have stopped or at least reduced using air conditioners?
A paradox of our times is the ever increasing popularity of ACs. As the temperatures soar high, one summer thought that comes to everyone’s mind is to get the house or office air conditioned. It is impossible today not to see an advertisement by the manufacturer, a discount offer by the distributor or a sales pitch by the shop outlet during a casual day out in the city. No cars are being made now without AC, and non-air conditioned hotel rooms are already hard to come by. Even small shops in small towns are boasting of AC.
Just in a decade or two, how come this technology has swept across all climatic zones – hill stations like Matheran, dry regions like Ladakh, rain forests of Wayanad, monsoon city of Mangaluru – as if this is a singular solution to human suffering. Ironically, the comfort that’s promoted here is not the real scientific biological comfort defined by dry bulb temperature, wet bulb temperature, humidity, air change, body level breeze and such indoor conditions.
Equally surprising, from an environmental perspective, not many people have spoken against this singular invention of humankind that demands lot of electricity thus causing depletion of fossil fuel; made from manufactured materials with high embodied energy; and contributes to greenhouse gas emissions and has been witnessing advancing technology, creating obsoleteness.
Just a habit
One major factor behind this spread is the human impulse for habit forming. For every car driver who claims it is too hot outside, there would be thousands of people walking or working outside in the same high heat. The car owner has simply lost the body capacity to bear heat. Air conditioner conditions us, and it is as habit forming as alcohol is. If we ask anyone habituated to an air conditioner, if they were miserable failures at home or work before they lived with air conditioners, no one would say ‘yes’. It would have been business as usual or possibly the financial success of those days has led them to new affordability now. By air conditioning, we do not sweat in summer, but make the Earth sweat. We do not shiver in winter, but make the Earth shiver. For millions of years, humans sweated and shivered, so the Earth survived.
Now that the Earth has started sweating and shivering in the form of climate change, it threatens the survival of humans. It is time we realise how our present actions can erase our future. It is time we realise how air conditioners can harm our health and endanger the Earth. Let us explore them in the coming essays
