Summer heatwaves can turn a good night’s sleep into a restless, sweaty ordeal. When temperatures soar, falling asleep and staying asleep becomes a challenge for many (myself included!). Fortunately, there are practical ways to cool down your bedroom and body, helping you get the restful sleep you need even during the hottest nights.


This guide shares effective sleep hacks to help you beat the heat and wake up refreshed, no matter how high the heat climbs.

Keep Your Bedroom Cool During A Heatwave


The temperature of your sleeping environment plays a huge role in how well you sleep. Experts recommend keeping your bedroom between 60 and 67 degrees Fahrenheit (15-19 degrees Celsius) for optimal rest. During a heatwave, this can feel impossible without some adjustments.


  • Use fans strategically

Position a fan near an open window to pull in cooler night air. Alternatively, place a bowl of ice or frozen water bottles in front of the fan to blow chilled air around the room.


  • Close blinds and curtains during the day

Blocking sunlight prevents your room from heating up. Use blackout curtains or reflective blinds to keep the heat out.


  • Switch off heat-generating electronics

Devices like TVs, computers, and lamps emit heat. Turn them off or unplug them before bedtime.


  • Consider a portable air conditioner or evaporative cooler

If you live in a dry climate, evaporative coolers can be energy-efficient options to lower room temperature.


Choose Bedding That Breathes


Your bedding can trap heat or help wick it away. Selecting the right materials makes a big difference.


  • Opt for natural fibers

Cotton, linen, and bamboo sheets allow better airflow and absorb moisture, keeping you cooler than synthetic fabrics.


  • Use lightweight blankets or no blanket at all

Heavy comforters trap heat. Try a thin cotton sheet or sleep without a cover if comfortable.


  • Avoid memory foam mattresses or toppers

These materials retain heat. If you have memory foam, consider a breathable mattress protector or cooling gel pad.


Adjust Your Sleepwear


What you wear to bed affects your body temperature.


  • Wear loose, lightweight clothing

Choose breathable fabrics like cotton or moisture-wicking blends.


  • Sleep without socks

Keeping feet cool helps regulate overall body temperature.


  • Avoid tight or layered clothing

Restrictive clothes trap heat and reduce airflow.


Use Cooling Techniques on Your Body


Lowering your core temperature before and during sleep helps you fall asleep faster and stay asleep longer.


  • Take a lukewarm shower before bed

A warm shower followed by evaporation cools your skin.


  • Apply a cool compress

Place a damp washcloth or cooling gel pack on your forehead, neck, or wrists.


Some pillows contain cooling gel or breathable materials that reduce heat buildup.


  • Stay hydrated

Drink water throughout the day but avoid large amounts right before bed to prevent waking up.


Create a Sleep-Friendly Routine


Your habits can either help or hinder sleep during hot weather.


  • Avoid caffeine and heavy meals late in the day

Both can raise your body temperature and disrupt sleep.


  • Limit physical activity close to bedtime

Exercise raises your core temperature. Finish workouts at least 3 hours before sleeping.


  • Wind down with relaxing activities

Reading, meditation, or gentle stretching can help your body cool down naturally.


  • Keep a consistent sleep schedule

Going to bed and waking up at the same time helps regulate your internal clock.


Use Technology Wisely


Some gadgets can help you stay cool and improve sleep quality.


  • Sleep trackers with temperature sensors

These devices monitor your sleep environment and body temperature, helping you adjust habits.


  • Sleep Music

Listening to calming sleeping music can actually help distract your brain from the heat, and help you fall asleep faster.


  • Cooling mattress pads

Powered pads circulate cool water or air to keep your bed comfortable.


Manage Humidity Levels


High humidity makes heat feel worse and disrupts sleep.


  • Use a dehumidifier

Lowering humidity below 50% helps sweat evaporate, cooling your body.


  • Ventilate your room

Open windows during cooler parts of the day to exchange moist air.


  • Avoid indoor plants that increase humidity

Some plants release moisture into the air, raising humidity levels.


Consider Sleep Position


How you lie down can affect heat retention.


  • Sleep spread out

Avoid curling up, which traps heat.


  • Elevate your feet

Raising feet slightly can improve circulation and cooling.


  • Use minimal bedding

Let your skin breathe as much as possible.


When to Seek Help


If heatwaves cause persistent sleep problems, consider consulting a healthcare provider. Chronic sleep deprivation affects mental and physical health. They may recommend additional strategies or treatments.
