The modern air conditioner was invented in the 1920s, but it didn't become a household staple until the late 20th century.
So how did our ancestors beat the summer heat? Discover 5 proven tricks they used to cool homes naturally, without AC. See how below:
Your grandparents likely remember chilly baths in large metal tubs. These weren't just refreshing—they kept homes cooler by skipping the need to heat water on the stove.
The cool bathwater also lowered the room's temperature. Before refrigerators, families used ice coolers in the basement, storing big ice blocks to chill food and create rising pockets of cool air that circulated through the house.
To endure heatwaves, ancestors opened basement and upper-floor windows, creating a siphon effect for better fresh air circulation.
When electric fans arrived, they amplified this: one in the basement pulling in cool air, another upstairs expelling hot air. Some placed ice blocks in front of fans for extra chill. Find out how here.
Many homes featured transoms—small windows above doors—that acted like natural fans in hot weather.

In tropical regions' old homes, like this 1940s example, tall sash windows slid vertically. During the day, they opened the top to vent hot air; at night, the bottom to draw in cooler outdoor air.
Thick curtains blocked sun while allowing light, enhancing comfort.
Verandas weren't just for rocking chairs—they shaded walls, blocking sun and cooling incoming air. Southern homes often wrapped around them entirely.
On scorching days, families slept there, using a damp sheet over benches or chairs for evaporative cooling. Check out the trick here.
This 1865 Victorian home boasts 3.7-meter ceilings and deep sills signaling thick brick walls—30 to 60 cm in many 19th-century builds.
