Struggling to fall asleep on hot summer nights is a common problem, especially as global temperatures rise.

It’s clear to the staff at Nifty Cool Stuff – our online lifestyle store – that cooler sleeping conditions are essential for good rest, but in many parts of the world, nighttime temperatures are increasing faster than daytime ones.

As a result, many people are losing sleep. Studies suggest that on particularly hot nights – those over 86°F (30°C) – people can lose an average of 14 minutes of sleep. Over a year, this adds up to around 44 hours of lost rest.

While it may be tempting to rely on air conditioning, it's not always a practical or environmentally friendly solution. Air conditioners consume a lot of energy, put stress on power grids, and aren't accessible to everyone

Fortunately, there are several effective strategies that can help you sleep better during a heat wave – without depending on AC.

1. Keep Your Bedroom Cool and Airy

Your body’s ability to fall asleep is closely linked to its internal temperature regulation. As you prepare for sleep, your core temperature naturally begins to drop, releasing heat primarily through the head, arms, hands, legs, and feet.

When the air around you is too warm, it becomes harder for your body to cool down enough to transition into sleep.

To keep your bedroom cooler:

• Close blinds or curtains during the day to block out sunlight.
• Open windows at night or early morning if the outside air is cooler.
• Leave bedroom doors open to promote air circulation throughout the home.
• Use fans to increase airflow. However, if indoor temperatures are extremely high – into the upper 90s – fans that merely circulate air won’t effectively cool you down and may not prevent heat-related illnesses.

2. Use Lightweight Covers

While it might seem logical to sleep without any covers during a heat wave, going entirely without a blanket isn't always the best idea.

Body temperature can drop while you're asleep, and a lightweight sheet or breathable blanket can help maintain comfort through the night. Materials like cotton or linen are good options, as they allow for better airflow and moisture absorption compared to synthetic fabrics.

3. Skip the Cold Shower – Go Lukewarm Instead

A pre-bedtime shower can help you cool down, but it’s best to avoid water that’s too cold. Extremely cold showers may be jarring and could cause your heart rate to increase, making it harder to relax and fall asleep.

A lukewarm or mildly cool shower is more effective and comfortable. Leaving your skin and hair slightly damp afterward can provide added cooling as the moisture evaporates. Another helpful trick is to place cool, damp washcloths on areas like your forehead, hands, or feet, where the body tends to release heat more efficiently.

4. Change Where or How You Sleep

If you're sharing a bed with someone who generates a lot of body heat or sweats during sleep, consider sleeping separately on especially hot nights.

The floor can be a cooler alternative to a mattress, as warm air rises and cooler air settles closer to the ground. If your home has a basement or another cooler area, consider sleeping there. Even a small drop in ambient temperature can make a noticeable difference in how well you sleep.

5. Strengthen Your Sleep Routine

When perfect sleeping conditions aren't possible, reinforcing other healthy sleep habits can help make up the difference.

Make your room dark and quiet, and avoid screen time at least an hour before bed. Instead of watching TV or scrolling on your phone, wind down with calming activities like reading, light stretching, or meditation. These habits help cue your body and mind that it’s time to rest, which can be especially helpful when the heat makes it more difficult to drift off.

A More Restful Night – Even in the Heat

Hot nights are becoming more common, and they can significantly disrupt sleep. But by making simple adjustments to your environment and bedtime routine, you can create conditions that support better rest – without depending on air conditioning.

Focusing on airflow, using light bedding, avoiding overly cold showers, adapting your sleep location, and sticking to healthy sleep habits can all help you stay cooler and sleep more soundly through the heat.
