If you're a sweaty sleeper, summer can be a nightmare. Hotter temperatures make a restful night nearly impossible, even when you're above the covers. One thing you can do to avoid a damp, sticky bed and hours of tossing and turning is invest in some light, breathable pajamas.

Sleepwear made of natural materials like certain cottons and bamboo can powerfully cool the body and wick away moisture. To help you sweaty sleepers catch some zzz's, we've rounded up the most comfortable heat-regulating pajamas you can buy.

1. Lunya Cool Short Romper, $158

For a super chic sleep, this Lunya romper will keep you looking and feeling cool. It's made of Pima cotton infused with drying technology that quickly evaporates dampness by spreading it across more surface area. Plus, pure silver within the fabric provides antimicrobial properties that prevent odor.

2. Recliner Sleep Tee Set, $105

Made of bamboo jersey, this biodegradable, hypoallergenic pajama set is designed to naturally deodorize and regulate body temperature during sleep. The slouchy boat neck top is equipped with side vents for extra movement and airflow, while the ultra-lightweight shorts have a flexible waistband.

3. Cozy Earth Stretch-Knit Bamboo Classic Shorts Set, $149

If humidity is part of the problem for you, look to Cozy Earth. The company known for bamboo sheets also makes sleepwear in its most popular material, which regulates temperature, wicks moisture, and reduces humidity by 50%. This short sleeve shorts set is stretchy for every body type.

4. Slumber Cloud Stay Cool Sleepwear Women's Top, $79

Slumber Cloud has partnered with Swiss sleepwear startup Dagsmejan to develop innovative pajamas using natural eucalyptus fibers. With a luxurious feel, this flowy v-neck tee cools the body through gradual moisture evaporation and dries quickly thanks to exceptional moisture transport.

5. Cool-Jams Women's Moisture Wicking Short Panel Night Shirt with Pockets, $55
