Researchers have linked being too warm in bed at night to everything from increased insomnia to obstructive sleep apnea. Experts recommend keeping your room cold and dark for optimal sleep. So if you keep flipping your pillow over and over, trying to find the cool side when you are restlessly tossing and turning, it makes sense.
Sleeping with a fan on at night can help, but you can also help your pillow feel cooler by simply slipping it into a unique cover.
An added benefit of a cooling pillow cover is that you can use it with your favorite pillow. So whether you prefer a specialized pillow such as one that helps you stop snoring or prevents heartburn, or you just have a favorite brand, you can still enjoy a cooler place to rest your head at night.
The AllerEase cooling pillow protector is a zippered cover that encases your pillow and might just let you sleep more comfortably. If you suffer from specific allergies, it could also allow you to wake up feeling more refreshed, without the congested, puffy, uncomfortable effects caused by nasty allergens.
Made from 100% cotton, the cover is designed to be naturally cool and crisp. In addition, the cotton design is coated with a phase-change material (PCM) finish. This technology enhances the noticeably inviting cool-to-the-touch sensation by absorbing or releasing latent heat. The fabric is also hypoallergenic and blocks nonliving allergens, including dust mite matter, which can cause asthma-like symptoms.
The Allerest Cooling Pillow Protector comes in standard and king sizes, it’s easy to care for since you can toss it in the washer on cold and tumble dry on low. You can find them at Target stores or online, starting at about $11 each. However, though it has an endorsement from RealSimple, these pillow covers only have a handful of reviews, and most of them are negative. Buyer cafa wrote, “These pillow cases do NOT cool your pillows. In fact, my pillows are cooler without them. I would return them but I washed them before using like all bedding.”
Here’s another option: These Elegear cooling pillowcases don’t claim to be hypoallergenic, but for their ability to cool heads, reviewers are fans. These pillowcases earn an average 4.1 stars out of 5 from nearly 300 reviewers. The double-sided pillowcases have two fabrics: a silky synthetic blend on one side for summer and cotton on the other side for all other seasons.
The product description says the cooling side has “added the jade masterbatch (a substance that provides a cool feeling) in the nylon fabric. It can absorb the body heat and drops quickly temperature by about 2 degrees.” That’s quite the claim, But reviewers seem to think the fabric is effective. “I really did not expect this to work as well as it did,” wrote Kristin under a review entitled, “It actually does stay cold!”
