How ancient Bhopal stayed cool without modern technology

Bhopal’s summers have grown longer and hotter over time. In the past, the city’s climate was milder, shaped by dense forests and clever building techniques. Ancient residents relied on natural methods to stay cool—long before electricity became common. Thousands of years ago, Bhopal was slightly cooler due to thick green cover. Pollen records reveal past monsoon patterns and a gentler summer. But as forests shrank, the city’s heat intensified, stretching the hot season.

Homes in ancient Bhopal were designed to beat the warmth. Every house had an *angan*—a central courtyard—that helped air circulate and lower temperatures. Jali, or latticework, filtered sunlight while allowing breezes to pass through. Walls made from local materials absorbed less heat, keeping interiors comfortable. Residents also adjusted their daily lives to avoid the worst of the sun. They woke at dawn and rested during peak afternoon hours. For extra relief, they hung *khus* (vetiver grass) mats or damp jute ropes near windows, which cooled the air as it passed through. Terracotta pitchers, or *matkas*, stored water and kept it refreshingly cold—a practice dating back over 7,000 years.

The loss of green spaces has made Bhopal’s summers more extreme. Traditional cooling methods, from courtyard designs to natural materials, show how past generations adapted. These techniques, once essential, now offer lessons for coping with rising temperatures today.
