This guide shares practical tips for hot sleepers that actually work, plus product recommendations that can transform your bedroom into a cool sanctuary. From choosing the best sheets for hot sleepers to finding the perfect cooling mattress, we'll cover everything you need for better, cooler sleep.

Tips on How to Stay Cool During Summer Nights

Hot summer nights don't have to mean tossing and turning until dawn. The key is creating the right environment and choosing bedding that works with your body, not against it. These proven strategies help regulate your body temperature naturally, so you can enjoy deep, restorative sleep even when the mercury rises.

Keep the curtains closed during the day

Direct sunlight streaming through windows can raise room temperature by several degrees, creating a greenhouse effect that lingers well into the evening. Here are some quick tips to prevent that heat buildup and keep your room cooler by bedtime:

  • Close curtains or blinds during the hottest hours (10 AM to 4 PM) to block sunlight.
  • Use blackout or thermal curtains to reduce heat buildup. They're particularly effective for south- or west-facing bedrooms that get intense afternoon sun.
  • Consider reflective window film to deflect sun rays before they enter the room.
  • Ventilate strategically by opening windows early in the morning or late at night when outdoor temperatures are lower.

Just these simple steps can prevent your bedroom from overheating and set you up for a more comfortable night.

Stick to light, breathable bedding

Lightweight, airy bedding is your best friend on warm nights. The best sheets for sleepers who experience night sweats prioritize both breathability and moisture-wicking properties. Try these bedding swaps for a cooler, more comfortable sleep:

  • Opt for linen for its airy weave and rapid moisture absorption.
  • Try bamboo sheets; they wick away sweat and help prevent odours.
  • Choose cotton percale for a crisp, cool feel that doesn’t trap heat.
  • Swap out heavy or dense fabrics for lighter weaves; thread counts between 200–400 strike the right balance between comfort and breathability.
  • Select a cooling duvet or comforter filled with down alternative or bamboo to help regulate temperature.
  • Upgrade to cooling pillows and mattress toppers designed to draw heat away and improve airflow.
  • Layer with a breathable blanket so you can adjust your covers as needed through the night.

Small changes to your bedding can have a noticeable impact on how refreshed you feel by morning.

The best sheets for hot sleepers are made from natural, breathable materials that allow air to flow freely. Linen sheets top the list for their loose weave and moisture-wicking properties. Cotton percale is another excellent choice—its crisp, breathable weave promotes airflow better than dense sateen cotton.

Top cooling bedding choices for hot sleepers:

Avoid synthetics! They trap heat

Synthetic materials like polyester and microfibre might be budget-friendly, but they're terrible choices for hot sleepers. These fabrics don't breathe well and tend to trap heat and moisture against your skin.

Instead of synthetic sheets, invest in natural materials that work with your body's cooling system. Cotton, linen, and bamboo all allow heat to escape while wicking moisture away from your skin.

The same rule applies to mattress toppers and pillows. Memory foam toppers, while comfortable, can retain heat. If you love the feel of memory foam, look for gel-infused options designed for cooling.

Try a summer quilt for just the right weight

Heavy comforters and thick duvets are perfect for winter, but they'll leave you overheated during warmer months. Summer quilts offer the perfect solution—they provide just enough coverage without the bulk. Here are quick tips for choosing comfortable, cool coverage:

  • Choose fills like cotton or bamboo—they’re breathable and stay cool.
  • Avoid dense, heavy duvets designed for winter.
  • Look for lightweight comforters with low fill power (400–500).

Summer quilts have fillings substantial enough to provide that cosy feeling many people need to fall asleep, but light enough to prevent overheating.

What's the best mattress to stay comfortable without getting too warm?

Your mattress plays a crucial role in temperature regulation. Traditional memory foam mattresses, while supportive, often trap heat because the dense foam doesn't allow airflow.

The best mattress for hot sleepers incorporates cooling technologies and breathable materials. Look for mattresses with:

  • Innerspring or hybrid construction that allows air to circulate through coil systems
  • Gel-infused memory foam that dissipates heat more effectively than traditional foam
  • Latex layers that naturally regulate temperature and resist heat retention
  • Cooling covers made from breathable, moisture-wicking fabrics

Many modern cooling mattresses also feature phase-change materials that actively absorb and release heat to maintain optimal temperature. While these tend to be more expensive, they can be game-changers for chronic hot sleepers.

Which duvet is best for preventing overheating while you sleep

The best duvet for hot sleepers balances coverage with temperature control. Traditional down duvets, while luxurious, can trap too much heat for warm sleepers.

Down alternative duvets often work better for hot sleepers. They provide similar fluffiness to down but with better breathability. Look for fills made from materials like bamboo fibre or Tencel, which naturally regulate temperature.

Cooling comforters designed specifically for hot sleepers feature lightweight fills and breathable covers. Many use moisture-wicking fabrics that help keep you dry throughout the night.

For the ultimate in temperature control, consider a duvet for hot sleepers with dual zones—different fill weights on each side accommodate partners with different temperature preferences.

Can a weighted blanket work for hot sleepers

Weighted blankets aren't off-limits if you run warm at night—just look for styles designed to keep you cool. Here’s what to consider for a comfortable experience:

  • Choose breathable covers like bamboo or cotton over synthetics.
  • Opt for glass bead filling, which promotes airflow better than plastic pellets.
  • Select a lighter weight (about 10–12 pounds) to prevent overheating.
  • Seek out moisture-wicking technologies or fabrics to help manage sweat.

Go for these cooling options and you can still enjoy the soothing pressure of a weighted blanket without sacrificing a cool, restful sleep.

Other Tips for Hot Sleepers

Beyond choosing the right bedding, several lifestyle adjustments can help you stay cooler while sleeping. These simple changes work together with quality bedding to create the ideal sleep environment.

Don't skip laundry day

Clean sheets don't just feel fresh—they actually sleep cooler. Body oils, dead skin cells, and sweat residue build up in bedding over time, reducing breathability and creating an environment where heat gets trapped.

Wash your sheets weekly in cool water to maintain their cooling properties. Skip fabric softener, which can coat fibres and reduce their ability to wick moisture.

Hot sleepers should also consider having multiple sets of sheets. This allows you to wash bedding more frequently without worrying about wait times for drying.

Wear light, breathable sleepwear

Your clothing can either help or hinder your body’s cooling process. Choose lightweight fabrics like cotton, bamboo, or linen in loose-fitting styles to let air circulate and heat escape.

Avoid polyester, nylon, or heavy blends, which trap warmth and can make you feel clammy. If you tend to sweat at night, moisture-wicking sleepwear is a smart choice.

Stay hydrated

Staying well-hydrated supports your body’s ability to maintain a stable temperature. When you're dehydrated, your body has to work harder to cool itself, potentially leading to more night sweats and discomfort.

Drink water regularly throughout the day so you’re not playing catch-up at night. Cut back a few hours before bed to reduce bathroom trips, and skip alcohol and caffeine, which can interfere with cooling and disrupt sleep.

Use a fan or air conditioner

Airflow speeds up evaporation, helping your body release heat. Ceiling fans, tower fans, or even a small bedside fan can keep air moving around you.

If you use AC, set it to 18–20°C for optimal comfort and use a programmable thermostat to maintain a steady temperature all night.

Sweaty Nights? No More!

Keeping cool at night comes down to a few key habits and smart product choices. Here’s a quick recap of proven strategies for staying cool:

  • Keep curtains closed during the day to prevent heat buildup
  • Choose breathable bedding made from natural materials like linen or cotton percale
  • Avoid synthetic fabrics that hold in heat and sweat.
  • Use lighter bedding like summer quilts instead of heavy comforters
  • Invest in cooling bedding products like gel-infused memory-foam mattresses and cooling pillows
  • Maintain clean bedding with regular washing
  • Wear breathable sleepwear made from natural fibres
  • Stay hydrated throughout the day
  • Use fans or AC to maintain comfortable room temperature

Following these tips for hot sleepers can dramatically improve your sleep quality. Start with one or two changes and gradually implement others to find what works best for you.
