Engineering airflow: stack effect and narrow passages

🔥🌙 Ancient Egypt faced brutal daytime heat, yet people still slept, rested, and lived along the Nile for thousands of years. Through clever architecture, airflow, shaded courtyards, lightweight clothing, water cooling, and nighttime routines, Egyptians worked with the desert climate instead of fighting it. Sleep came after sunset, often outdoors or near open windows, guided by wind, water, and habit.

Tonight, close your eyes and drift into quiet courtyards, reed mats, and cooling river breezes — a calm lesson in surviving heat long before electricity existed.
