5 Cheap(ish) Things to Keep Your Bedroom Cool (2024)

The first summer I lived in New York City was a sweltering reality check. Coming from the Northwest, I had never had an air conditioner, and I didn’t think I could afford one (or the higher electric bills). I spent that first summer tossing and turning in the muggy heat. By the following summer, I had wised up and invested in an A.C., but even then the window unit didn’t effectively cool my space.

An air conditioner is the obvious best fix for a hot bedroom. But if you don’t have one, there are some relatively simple and affordable steps you can take to keep your bedroom cool. And if you do have one, you can maximize all that conditioned air by keeping heat from entering your bedroom — or the cool air from escaping. Switching up your bedding can also go a long way to making you more comfortable.

With that in mind, here are five cheap(ish) things to help keep your bedroom cool even on the hottest nights of summer.

(And if you’re looking to invest in an A.C., Wirecutter has recommendations for window units and brackets to install them, as well as portable units for when a window A.C. isn’t an option.)

Blackout shades

Window treatments can make a big impact on keeping your room cool. Nearly any shades or curtains will help reduce solar heat coming through the windows, but some are better at the job than others. Insulated cellular shades are particularly effective at blocking out light, but a paper option like the Redi Shade Original Blackout Pleated Paper Shade should also get the job done. While these shades won’t keep all the sunlight out, they still blocked a significant amount of light in our tests. These paper shades can be cut to custom fit your windows, and are easy to install, with a peel-and-stick application process. Shades should fit tightly, meaning no gaps at the sides of the window frame.

Weatherproof your windows

Drafty windows and gaps under a door can defeat much of the work of an air conditioner. Leaks from the windows and under doors can let hot, humid air inside (and allow cool, conditioned air to escape).I realized this firsthand a few summers ago, when my apartment remained stubbornly muggy despite cranking my A.C. unit. After I stuffed foam weatherstripping in the gaps of my windows, I noticed an immediate improvement in the chill factor. To fill any gaps along the side rails of single- and double-hung windows, or around a window A.C. unit, Wirecutter recommends V-seal stripping and foam strips. In a pinch, you can also use a rolled-up towel at the bottom of a door to help keep cool air inside.

A good fan

A fan won’t lower the temperature of your room, but it will move the air around, which can make you feel cooler by helping sweat to evaporate. Wirecutter recommends the Dreo Fox One as its budget pick. We like that it’s quiet, effective and affordable. For those without air conditioning, you could also use a window fan like the Bionaire Twin Reversible Airflow Window Fan to draw cool air into your room. Just keep in mind that window fans are most effective at cooling when used in a mild or dry climate.

Cool, crisp sheets

Just as the shift of seasons calls for a change of wardrobe, switching to lighter sheets will help you stay more comfortable in warm weather. I prefer linen sheets, because they’re extremely breathable, but they can be quite pricey. For a more affordable option, Wirecutter recommends a variety of lightweight percale sheets, including affordable sets from L.L. Bean and Brooklinen. While they’re less expensive than linen, they’re not dirt cheap; in tests, Wirecutter found that really inexpensive percale sheets can feel very scratchy.

A lightweight blanket

Spring and summer nights can be unpredictable, so it’s good to layer linens, just as you do with clothes. If you want something that’s just slightly heavier than a top sheet, consider the Riley Textured Cotton Coverlet, Wirecutter’s pick for a gauze blanket that’s durable, breathable, and looks nice in the room. It snags easily, but it’s very breathable and affordable. If you need something more substantial for cooler nights, Wirecutter recommends the L.L.Bean Maine-Made Cotton Twill Blanket. It’s the perfect weight for a New England or Northwest summer.
