• Cooling pajamas are just one way that hot sleepers can find relief.
• We tested several pairs made from cooling fabrics to see which ones actually helped keep us from waking up in a puddle of perspiration.

If you wake up hot and sticky from perspiration, as if your body cranked up its internal temperature to sauna status, you're not alone. Over the last year or so, I've become a hot — and, admittedly, a very sweaty — sleeper. I wake up warm almost every morning, sometimes even in the middle of the night, regardless of how cool my husband and I keep our bedroom or how light our bed sheets are. But just when I thought I'd exhausted all my resources, a loved one recommended swapping out my sleepwear for cooling pajamas. Now, thanks to this simple switch, beauty sleep has meaning again.

What to look for in a pair of cooling pajamas, according to a sleep psychologist

A fresh pair of cooling pajamas might just be your saving grace if you're also someone who constantly wakes up hot and sweaty. When shopping for new sleepwear, health and sleep psychologist Joshua Tal, PhD tells INSIDER that shoppers should look for fabrics like cotton, linen, bamboo, and rayon, as these materials "allow your body to release moisture, but [are] loose enough to let air in to cool you down and wick away the moisture." Eucalyptus fibers are also great, as they're ultra-lightweight, hypoallergenic, moisture-wicking, and cool to the touch, adds Elle Liu, founder of cooling sheets brand, Eucalypso.

It's also worth noting that, while the term "cooling pajamas" doesn't have the sexiest connotation, you can rest assured these sleep garments come in an array of styles. From tank tops and shorts to flowing nightgowns and form-fitting garments, read on to find out which cooling pajamas we've tested and loved.

How we tested these cooling pajamas:

I slept in nearly a dozen pairs of cooling pajamas for this test, but in order to determine the best, I had a few criteria that needed to be met. First, they had to be lightweight; I didn't want to feel like I was swimming in material or being weighed down. Secondly was the sweat factor: Was I still waking up in a pool of perspiration with my clothes sticking to my skin? And, finally, were the pajamas cooling enough that I slept through the night? This list only include the ones that were most comfortable, fit properly, and prevented my nightly hot flashes from becoming puddles of sweat.
