Tips to Beat the Heat 

beat the heat with bamboo sheets

As global temperatures continue to rise and heatwaves become more frequent and intense, getting a restful night’s sleep during summer can feel like a battle against the elements.

If you’ve ever tossed and turned on sweat-soaked sheets or woken up feeling more exhausted than when you went to bed, you’re not alone. But there’s hope! With smart strategies and a few summer-friendly tweaks, your bedroom can become a cool oasis—even on the hottest nights.

Here are the best expert-backed tips to beat the heat in the bedroom this summer of 2025, from high-tech solutions to natural cooling methods.

1. Choose Breathable Bedding Materials

Not all sheets are created equal. Synthetic materials like polyester tend to trap heat, making you feel warmer at night. Instead, opt for natural, breathable fabrics.

Best Cooling Fabrics:

  • Bamboo: Ultra-soft, moisture-wicking, naturally cooling, and sustainable.

  • Linen: Great airflow and a rustic feel, ideal for hot sleepers.

  • Cotton Percale: Crisp and lightweight, with a cool-to-the-touch feel.

  • Eucalyptus/Tencel: Silky and naturally antimicrobial, perfect for sensitive skin.

Look for sheets with a thread count between 250 and 400 for maximum breathability.

2. Use Lightweight Bedding Layers

Switch out your heavy comforter or duvet for something summer-appropriate:

  • Replace your winter duvet with a lightweight summer quilt or blanket.

  • Use a cooling blanket made with temperature-regulating materials.

  • Keep an extra thin sheet nearby in case temperatures drop slightly during the night.

Pro tip: Layer your bedding so you can add or remove warmth without getting up.

3. Invest in a Cooling Mattress or Topper

A lot of heat is trapped in your mattress. If yours retains heat, it may be time to upgrade.

Cooling Mattress Features:

  • Gel-infused memory foam

  • Breathable coil systems

  • Copper-infused or graphite layers

  • Moisture-wicking covers

Alternatively, consider a cooling mattress topper as a budget-friendly fix. Look for ventilated memory foam, bamboo fiber, or latex options that allow for better airflow.

4. Use a Cooling Pillow

Don’t underestimate the impact of your pillow on sleep temperature.

Look for:

  • Cooling gel memory foam

  • Bamboo or Tencel pillowcases

  • Buckwheat pillows, which allow excellent airflow

  • Pillows with phase-change materials (PCMs) that adjust to your body heat

Flip your pillow halfway through the night for a refreshing cool side.

5. Optimize Your Bedroom’s Airflow

Daytime:

  • Close blinds or curtains to block out the sun.

  • Use blackout or thermal curtains to reduce indoor heat.

  • Keep windows shut during the hottest part of the day.

Evening:

  • Open windows after sunset to let cooler air circulate.

  • Use a box fan in the window to pull hot air out.

  • Create a cross breeze by opening windows or doors on opposite sides of the room.

Adding a ceiling fan or oscillating floor fan will help maintain circulation.

6. Create a DIY Air Conditioner

Here’s a popular home hack:

  • Place a bowl of ice or frozen water bottles in front of a fan.

  • As the fan blows over the ice, it creates a cooling mist.

It’s a simple trick, but it works surprisingly well for small rooms.

7. Try a Bed Cooling System

If you’re a tech-savvy sleeper, consider high-tech sleep systems designed to regulate temperature:

Popular Cooling Systems (2025):

  • Eight Sleep Pod: Smart mattress with temperature control and sleep tracking.

  • ChiliPad Dock Pro: Water-based cooling pad placed under your sheets.

  • BedJet 3: Air-powered cooling (or heating) device that blows under your sheets.

Though pricey, these gadgets can dramatically improve sleep for hot sleepers.

8. Keep Electronics Out of the Bedroom

Electronics emit heat—even when in standby mode.

Avoid:

  • TVs

  • Laptops

  • Chargers

  • Game consoles

Keep them in another room or unplug them at night. Also, avoid using heat-producing devices like hairdryers or irons in the bedroom before bed.

9. Sleep Low to the Ground

Heat rises. If your bed is close to the ceiling or in an attic room, you’re more likely to feel the heat.

Cooling Sleep Setups:

  • Try a low platform bed or floor mattress.

  • Avoid loft beds or tall frames in the summer.

  • If possible, sleep in a lower-level room, such as a basement.

10. Take a Cool Shower Before Bed

A lukewarm or cool shower about 30 minutes before bed lowers your core body temperature. It also helps rinse off sweat and body oils that might trap heat in your sheets.

For extra cooling:

  • Add a few drops of peppermint essential oil for a refreshing tingle.

  • Let your hair air-dry instead of blow-drying.

11. Hydrate for Better Thermoregulation

You lose a surprising amount of water during sleep, especially on hot nights.

  • Drink water throughout the day, not just before bed.

  • Avoid alcohol and caffeine close to bedtime—they dehydrate you and raise your body temp.

  • Keep a cold water bottle near your bed for midnight sips.

Bonus: Frozen water bottles can also double as ice packs under your feet or behind your neck.

12. Sleep Solo (If You Can)

Sharing a bed means shared body heat. If you and your partner are both hot sleepers:

  • Try sleeping under separate blankets.

  • Use cooling sheets and pillows on both sides.

  • Cuddle before sleep, then separate for cooler comfort.

Pet owners may also want to consider keeping furry companions off the bed during the hottest months.

13. Wear Breathable Sleepwear

Ditch flannel and thick fabrics. The best summer sleepwear is:

  • Loose-fitting

  • Made from cotton, bamboo, or moisture-wicking blends

  • Sleeveless or short-sleeved

Alternatively, sleeping nude or in minimal clothing can also reduce heat buildup—just make sure your bedding is soft and non-irritating.

14. Keep Lights Dim or Off

Incandescent bulbs emit heat. Even LEDs give off some warmth. During summer nights:

  • Use minimal lighting.

  • Choose LED bulbs labeled “cool white.”

  • Try motion-sensor or touch lamps to avoid constant switches.

The darker your room, the less trapped heat you'll retain.

15. Try Natural Cooling Aids

There are plenty of budget-friendly, natural ways to stay cool:

  • Aloe vera gel on skin for cooling and hydration

  • Peppermint spray (a few drops of oil in water) misted on sheets

  • Cold compresses behind knees, on neck, or wrists

  • Chilled rice packs or gel pads tucked under your pillow

16. Chill Your Sheets or Pillowcases

Throw your sheets or pillowcases in the freezer for 20–30 minutes before bed. It might sound quirky, but the instant relief can help you fall asleep faster. Just seal them in a plastic bag to avoid odors or condensation.

17. Use a Dehumidifier

Humidity can make warm temperatures feel unbearable. If you live in a humid area:

  • Use a dehumidifier to reduce moisture in the air.

  • Keep humidity below 50% for optimal comfort.

  • Bonus: Less humidity means fewer dust mites and allergens.

18. Blackout Curtains for Daytime Cooling

Sunlight heats up your room fast. Install thermal blackout curtains that reflect UV rays and insulate your windows.

  • Choose light-colored curtains with a thermal lining.

  • Close them by 10 AM and open again at night to release trapped heat.

19. Consider Window Films or Reflective Shades

DIY window solutions can block significant heat.

  • Reflective window film can block up to 80% of solar heat.

  • Exterior or interior heat-reflecting shades or solar blinds also work wonders.

These upgrades are inexpensive and easy to apply.

20. Adopt a Mediterranean Schedule

Countries in hot climates take midday breaks for a reason.

  • If your schedule allows, take a siesta during the hottest part of the day (2–4 PM).

  • Shift physical activities to mornings and evenings.

  • Keep your evenings relaxing to prepare for a cool sleep.

Whether you’re facing a sweltering city heatwave or just trying to make summer nights more bearable, implementing even a few of these tips can help you wake up refreshed, cool, and ready to take on the day.

Final Quick List of Tips:

  • Choose breathable bamboo or linen sheets

  • Switch to a cooling pillow

  • Use blackout curtains during the day

  • Try a cool shower before bed

  • Place a fan over a bowl of ice

  • Keep electronics out of the bedroom

  • Use a dehumidifier if needed

  • Hydrate and avoid alcohol before bed

  • Sleep low, solo, and minimally clothed

Sweet dreams—minus the sweat.
