We saw extreme temperatures plague the US this summer. While the season is coming to a close, you might still find it hard to get a good night’s sleep when you can’t get cool or comfortable. High temperatures can interfere with the body’s natural thermoregulation progress and make it feel like you’ll never be able to lower yours enough to drift off into a peaceful slumber.
Don’t worry; you’re not doomed to sweaty sheets and a sky-high energy bill. There are things you can do (outside of your air conditioning) to beat the heat. Try these 12 recommendations to kick the night sweats and sleep through the night. Plus, how to sleep cooler when you share a bed with a human furnace.

1. Talk to your doctor about night sweats
First things first: Rule out an underlying health condition. Night sweats can happen in response to many medical conditions, including anxiety disorders, neuropathy, hyperthyroidism, Hodgkin’s lymphoma and tuberculosis, according to the Mayo Clinic.
Certain medications, such as those for diabetes and depression, may also cause night sweats. If you’re waking up hot and sweaty every night, it’s worth looking into with your doctor, regardless of the weather.

2. Add a window unit or box fan
This probably seems obvious but it works. If you don’t have central AC in your home, consider buying a window unit to keep you cool at night. This costs far less than installing a central AC unit and it saves on energy costs because you’re only cooling one room. Alternatively, a box fan in the window can push hot air out and circulate cooler air.
3. Try a floor fan or mini nightstand fan
No space for a window unit or box fan? Many companies make impressively powerful floor fans and mini fans these days. The Honeywell QuietSet Whole Room Tower Fan has served me well, as has the Honeywell Dreamweaver Sleep Fan, which doubles as a white noise machine.
4. Use fans to create a cross-breeze
Speaking of fans, grab two while you’re at the store. Placing two floor fans facing each other on opposite sides of your room creates a cross-breeze, keeping you cool all night long.
This small Honeywell fan is surprisingly powerful.
5. Take a hot bath a couple of hours before bed
Your body temperature fluctuates in a cycle. Every evening, as the sun begins to set and your eyes perceive darkness, your body starts to produce melatonin and triggers your brain to prepare for sleep. At the same time, your core body temperature begins to dip and continues to drop throughout your first two stages of sleep.
Taking a hot bath 1 to 2 hours before bed can simulate this natural process and promote restful sleep. When you sleep, your body temperature hovers around 2 degrees lower than its daytime temperature before gradually rising back to normal levels shortly before you wake up.
It might sound like the opposite of what you want to do, but it just might work.
6. Try bedding made from natural fibers
Synthetic sheets tend to cost less than natural sheets, but investing in some natural cotton, linen, silk or bamboo bed sheets might be your ticket to staying cooler while you sleep. These fabrics promote breathability, and as a bonus, they don’t put off volatile organic compounds like many synthetic fabrics do (we could all use fewer VOCs in our homes).

7. Choose natural fibers and loose fits for pajamas
If you don’t feel comfortable sleeping nude, be smart about your pajamas. Just as bedding made from natural fibers can help keep you cool, so can clothing. Loose-fitting cotton, silk or bamboo-based pajamas offer more breathability than pajamas made from synthetic fibers.
Pajamas made from natural fibers, like this bamboo fabric set from Cozy Earth, might help you stay cooler at night.
8. Use blackout or thermal curtains during the day
It’s always nice to let sunlight into your home during the day, especially during the winter, when days are short and many people struggle with seasonal affective disorder. Keeping the curtains — specifically blackout or thermal curtains — drawn in your bedroom during the day can keep your room cooler so it’s ready to sleep in at night.
9. Don’t run electronics in your bedroom
Electronics such as televisions, radios and video game consoles emit heat when they run. Avoid using electronics in your bedroom at night if you really struggle to stay cool while you sleep.

10. Try out a cooling blanket or pillow
You may have already tried putting your bedding in the freezer to give it a burst of cold when you finally go to sleep. While this may work for some, it’s also a potential way to invite mold into your bed due to moisture that can get trapped under your sheets.
Instead, try investing in a cooling blanket, sheet or pillow. These affordable accessories are created from a special fabric and will keep cool all night long on their own. While they may heat up slightly due to your body temperature, they return to their ice cold standard in minutes. They’re a great alternative to dragging potentially wet sheets into the bedroom and they come in many shapes, prints and colors at low prices at retailers like Amazon.

11. Turn down your thermostat
This probably seems obvious, but many people are hesitant to turn the thermostat down past a certain temperature. Turning your home into an arctic tundra via air conditioning jacks up your electricity bill, after all. If you feel like you’ve tried everything and you still wake up a sweaty mess, you might just need to nudge your nighttime temp down a few notches.
According to the National Sleep Foundation, most experts agree that 65 degrees Fahrenheit (18.3 degrees Celsius) is the ideal sleeping temperature because it helps your body maintain its natural core temperature at night. The US Department of Energy suggests that the ideal temperature for your thermostat this summer is 82 F when sleeping and 85 F when out of the house to ensure maximum energy savings. Be prepared to spend a little extra this summer if you’re changing the thermostat each night.
