6 Expert Recommended Bed Cooling Systems For Hot SleepersRD.COM, VIA MERCHANT (3)

For hot sleepers, there’s no dread like uncomfortably warm nights. No matter how low you turn the air conditioner or how strategically you place your cooling fan, it’s still possible to find yourself tossing and turning, overheating from your blankets and sheets. Fortunately, there’s a science-backed solution: a bed cooling system.

Instead of cooling the air around you, these bed cooling systems chill the air and fabrics in your bed. That means you get cooling that cuts straight to the source—and nips hot sleep in the bud. To enhance their benefits, use them with a cooling mattress and cooling weighted blankets.

We asked several sleep experts for their input in choosing the best bed cooling systems on the market. Here are the best of the best.

This air-based bed cooling system comes recommended by both Derek Hales, founder and editor-in-chief of NapLab, a sleep testing platform, and Stephen Light, CEO of Nolah Mattress and a certified sleep science coach. “The BedJet 3 is widely regarded as one of the finest cooling systems on the market,” says Light. “It circulates air through the tubes of a mattress pad, is incredibly easy to set up and is easily controlled with a remote or an app on your phone.”

This bed cooling system works with all mattresses and bed frames and is relatively inexpensive compared to other bed cooling products. What’s more, you can control the temperature to a specific degree and set each side of the bed to a different temperature.

“Finding a product that keeps me cool even on scorching summer nights is a downright miracle,” writes our shopping editor Stephanie Hope. “The BedJet 3 efficiently cools me down, providing exceptional airflow throughout the bed which has significantly improved my sleep. I wake up feeling refreshed and energized—without any pesky night sweats.” Read her in-depth review.

Elegear Revolutionary Cooling Blanket

If you don’t want to drop hundreds on a bed cooling system, try a cooling blanket before you invest in more expensive gear. This one from Elegear absorbs body heat and can reduce skin temperatures from 35 to 41 degrees.

“It is definitely cold but not overwhelmingly cold at all,” writes five-star reviewer, Madison Price. “It’s like flipping your pillow over the cold side, except it’s an entire blanket!”

The blanket comes in four sizes and weighs under 3 pounds, meaning it can provide cooling to one or more people or be brought on vacations or camping trips. Simply toss it in the washing machine to clean. For another excellent pick, check out the Dangtop cooling blanket too.

What to consider when buying a bed cooling system

Many people can benefit from a bed cooling system, from those who require one for medical reasons to those who simply prefer chilled bedding (think of cold sheets as a similar luxury as warm towels). “Anyone who finds they sleep hot at night, especially to the point it causes them to wake up, can benefit from a bed cooling system,” says Hales. These may include heavyweight sleepers, sleepers going through menopause, sleepers with medical conditions that cause them to sleep hot and sleepers who enjoy the feel of memory foam, but dislike its heat retention quality.

The benefits of bed cooling systems include improved sleep quality and duration. “When our bodies are too hot at night, it can be difficult to fall and stay asleep, tanking our sleep quality and blocking our bodies from repairing, recharging and refreshing in the way they need to,” says Light. “Bed cooling systems can ensure our bodies stay at the optimal temperature for high-quality sleep.”

Types of bed cooling systems

There are two types of bed cooling systems: passive and active. Passive systems provide a layer of cooling material and are typically seen in the form of cooling mattress pads, cooling blankets and cooling pillows. Active systems use either water or air to cool your mattress and bedding.

Air cooling systems are quite simple. “They create additional airflow to bedding and/or the mattress,” says Hales. “This helps bring cool air into the bedding system and push hot air out.”

Water cooling systems are somewhat more complex. “These involve channels of water running through a bedding attachment (typically a type of mattress pad) or through the mattress itself,” explains Hales. “The cooled water flows through the bedding, coming into contact with sleepers and cooling them.” The water is then cycled to an external device where it is re-cooled before channeling back into the bedding attachment or mattress.
