How to Stay Cool While Sleeping

How to Stay Cool While Sleeping

We've all been there - tossing and turning in bed, unable to escape the heat. While sleep is essential for our well-being, staying cool is often easier said than done.

This in-depth guide will provide you with proven strategies on how to stay cool while sleeping, even in the most challenging conditions.

How to Cool Yourself Down in Bed at Night

The Power of Cold Showers

Taking a cold shower right before hitting the bed might sound counterintuitive but it’s grounded in science. Cold showers can effectively lower your core body temperature, thus preparing your body for a restful night of sleep. By constricting the blood vessels and improving circulation, you’ll find it much easier to slip into a deep sleep.

Utilizing Cooling Products

From cooling lotions to sprays, there’s a wide range of products that offer immediate relief from heat. Designed to evaporate quickly and leave a cooling sensation, they can be an excellent short-term solution for hot sleepers.

Sleepwear Matters

What you wear to bed can significantly impact your thermal comfort. Opt for moisture-wicking fabric or even specialized cooling sleepwear that disperses body heat. Avoid heavy and non-breathable materials like polyester.

If you're looking for a more lasting solution, upgrading your mattress could be a smart move. Puffy mattresses, for instance, are engineered with climate-adaptive materials that regulate temperature.

How to Keep Cool While Sleeping

The Fan Game

Placing a fan strategically in your bedroom can do wonders. Not only does it circulate air, but if positioned correctly, it can draw in the cool evening air and displace the hot air trapped inside, creating a refreshing sleep environment.

Proper Bedding

Never underestimate the power of sheets and blankets. Opt for breathable options like cotton or bamboo that wick moisture away from your body. Avoid heavy materials that can trap heat, such as flannel or polyester.

Hydration is Key

Keeping a glass of cold water by your bedside isn’t just good for midnight thirst. The act of drinking cold water can help lower your internal temperature, although it’s advisable to consume it in moderation to avoid frequent trips to the bathroom.

How to Stay Cool While Sleeping Without AC

Ice Packs and Cold Towels

It may sound like a desperate measure, but placing ice packs or cold towels on your pulse points, such as wrists and temples, can dramatically cool down your entire body. The blood flowing through these areas will cool down and circulate back into your system, reducing your overall body temperature.

DIY Air Cooler

Don't have an air conditioner? A simple bowl of ice placed in front of a fan can act as a makeshift air cooler, dispersing cool air throughout the room.

Open Windows and Cross-Ventilation

If outside temperatures drop during the night, open your windows to let in the cool air. Make sure to set up a cross-ventilation system by opening windows on opposite sides of the room or house.

How to Cool a Mattress

Mattress Toppers

Investing in a gel-infused or memory foam mattress topper can add a layer of coolness to your bed. These materials are specifically designed to draw heat away from the body, offering a cooler sleep surface.

Under-the-Sheet Solutions

For more targeted cooling, consider bed cooling systems or cooling mattress pads. These products can actively regulate your mattress's temperature, providing a consistent cool sleeping surface.

While Puffy mattresses already come with a built-in cooling layer that helps to regulate temperature, you might consider their other sleep solutions for an even more refreshing sleep experience.

Additional Techniques

Stay Away from Caffeine and Spicy Foods

These substances can naturally elevate your body temperature. Try to avoid them, especially in the hours leading up to bedtime, to minimize night sweats.

Adopt the 'Egyptian Method'

This involves dampening a sheet in cold water and using it as a blanket. Although unconventional, it has been found effective. Be sure to place a dry towel underneath you to absorb any excess moisture.

Mindfulness and Relaxation Techniques

Deep breathing, guided imagery, and other relaxation techniques can help calm your mind, indirectly cooling your body by reducing stress-induced heat.


Can Drinking Cold Water Help?

Cold water can provide temporary relief, but it’s a double-edged sword. While it can cool you down momentarily, it can also disrupt your sleep by necessitating frequent bathroom visits.

How Do I Maintain a Consistent Cool Temperature?

In addition to bedding and sleepwear, consider using a smart thermostat or specialized bed cooling systems that can help maintain a constant temperature throughout the night.

Do Cooling Pillows Work?

Cooling pillows, typically made of gel or cooling foam, can provide immediate relief but be aware that the cooling effect may diminish as your body heat gets absorbed.
