Why Were Nalanda’s Rooms Cool Even in Summer? 😨#nalanda #nalandauniversity #shorts

In this video, we uncover the hidden science behind Nalanda Mahavihara, one of the greatest universities of the ancient world. Thousands of students studied here, yet the biggest mystery isn't its libraries or scholars—it's how the rooms remained comfortable during Bihar's scorching summers without fans or electricity. The secret was hidden inside the walls themselves. Nalanda's buildings were constructed using extremely thick brick walls with high thermal mass. During the day, these walls absorbed heat very slowly, creating a significant time lag before the heat could reach the interior. By the time the stored heat started moving inward, evening had already arrived and the outside temperature had begun to drop. This kept classrooms and living quarters surprisingly cool for most of the day. No fans, no air conditioners, and no electricity—just smart architecture, physics, and centuries-old engineering knowledge. 🔥
