Not everyone has air conditioning — and when a heatwave hits, a stuffy apartment can feel unbearable. The good news? You don't need expensive equipment to make your rooms noticeably more comfortable.
With a few clever tricks and some smart timing, you can keep the heat out and the cool in. Here are seven simple methods that actually work.
1. Hang a cold, damp towel in front of the fan
A damp towel or cloth placed near a fan can create a mild cooling effect, because evaporating water draws heat from the surrounding air.
Just be careful: never cover the fan itself or drape anything directly over the blades, as that can be a safety hazard. This trick works best for cooling a small area for a short time, not an entire room.
2. Keep your home dark during the day
This is one of the most effective solutions when you don't have AC. Direct sunlight heats up rooms quickly, so blinds, shades and thicker curtains help stop the heat from getting in.
Pay special attention to south- and west-facing windows, where the sun is strongest and does the most damage.
3. Ventilate at night, seal up by day
When the air cools down in the evening and overnight, it's worth opening several windows to let fresher air move through your home.
In the morning, do the opposite: close the windows and pull down the shades to trap that cooler temperature inside for as long as possible.
4. Use your fan the smart way
A fan doesn't actually cool the air in a room — it just moves it around, helping sweat evaporate from your skin so you feel cooler.
Position it wisely: in the evening, aim it toward an open window to push warm air out, or set it up to draw the cooler outside air in.
5. Blackout curtains against the worst heat
Proper shading is one of the easiest ways to stop your home from overheating. Blackout or thermal curtains block direct sunlight, so your rooms warm up more slowly on scorching summer days.
They're especially helpful on south- and west-facing windows, where the sun hits hardest. The key is to draw them before the heat builds up — ideally in the late morning, not once your apartment has already turned into an oven.
6. Put a frozen water bottle in front of the fan
Here's a simple upgrade to the airflow from your fan. Fill a few bottles with water, freeze them, then place them in front of the fan on a tray or towel.
The fan pushes air across the cold bottles, so the breeze feels cooler — and the tray catches any meltwater so there's no mess.
This method won't dramatically lower the room's overall temperature, but it can make things feel noticeably more pleasant for a while.
7. Let plants improve the feel of the air
Through transpiration, plants can slightly raise the humidity in the air and create a fresher, more pleasant feel indoors.
On their own, though, they can't meaningfully lower a room's temperature — so think of them as a nice complement to the other tricks rather than a standalone fix.
Does a fan actually cool the air in a room?
No. A fan doesn't lower the air temperature — it moves the air around and helps sweat evaporate from your skin, which makes you feel cooler.
What's the most effective way to keep a room cool without AC?
Blocking sunlight is one of the most effective methods. Keep blinds, shades and thick curtains closed during the day, especially on south- and west-facing windows.
When should I open the windows during a heatwave?
Open them in the evening and overnight when the air outside cools down, then close them and pull the shades in the morning to keep the cooler temperature inside.
Do frozen water bottles in front of a fan really work?
They can make the breeze feel cooler for a short time as air passes over the cold bottles, but they won't significantly lower the whole room's temperature.
