Traditional Indian cooling methods that still work today

In the absence of artificial air conditioners and other cooling technologies in India, people found many natural ways to combat the extreme heat. Several of such old-school cooling techniques involved effective management of airflow, provision of shades, usage of natural elements, and water-based cooling ideas. Quite intriguingly, quite a few of these concepts have come back into vogue nowadays as people seek energy-efficient cooling solutions. From clay pot cooling to khus screens and courtyard-style ventilation plans, traditional Indian cooling systems are still relevant today. There are at least six such techniques used till date to keep the home cool during summers

The old practice of storing drinking water in clay pots, also known as matkas, is among the most ancient Indian cooling systems. This simple method cools down the water by allowing it to evaporate slowly from the porous nature of the material. Drinking matka water provides a unique taste and makes people feel refreshed during the intense summer heat. Also, this age-old tradition reduces dependence on refrigerators to some extent.

During summer seasons, khus screens made of vetiver grass roots were hung close to windows and doors. As these screens were watered constantly, passing air through them resulted in natural evaporation process. As such, cooled air circulated inside the room. Before air coolers were common in Indian homes, many families used khus screens due to the added advantage of a mild earthy smell.

Many ancient houses in India were built with courtyards in the middle. This helped in better airflow as well as regulation of temperature levels in each corner of the house. Such architectural designs helped in letting out the heat that rose towards the ceiling. Thus, the air that circulated in the remaining parts of the home remained comparatively cooler. In many tropical areas, such homes continue to be constructed even today.

Instead of modern paint colors, ancient Indians often whitewashed their ceilings and walls during the summer season. Lime effectively reflected sunlight, unlike darker colors. It also reduced the amount of heat absorbed by the building. Therefore, the white roofs of ancient homes remained relatively cooler than other colored options. Till today, many people use lime coatings to reduce heat in homes.

While constructing homes, Indians traditionally preferred to use bamboo, cane or wood-based furnishings rather than synthetic materials. Since natural materials did not absorb much heat, they helped in better airflow through the space. Charpais, cane furniture pieces and bamboo-based window panes were quite popular as they were comfortable to use and offered better circulation during summer seasons.

Indians always used verandas and plants as cooling agents to reduce direct sunlight exposure in indoor living spaces. Tulsi plants, creepers and trees helped reduce heat in nearby areas naturally. Besides, verandas were ideal spots to relax in summer seasons before the advent of mechanical air conditioning units. Terrace gardening and balcony plants have recently become popular again.
