My personal feeling is that “cooling” sheets are a farce. They don’t cool, they just wick up your sweat after you get hot. You’re better off with natural materials. Either 100% percale cotton, or linen. Your mattress pad also matters a lot. Anything waterproof or plastic lined is going to make you sweat like crazy if you’re a hot sleeper. Try to get 100% cotton mattress pad, it will also sleep cooler than anything with artificial fill or fiber. It will also run you around $200 depending on size as well, unfortunately, but it’s worth it. I’d say more important than the sheets even. Same with your blanket or comforter. More on reddit.com

Cotton Percale, hemp, or linen. Sateen is worse than flannel it will make you extra warm. More on reddit.com

“Cooling” is a marketing gimmick. There’s no bedding material that will actively cool you. Fabrics that say they’re cooling are synthetic blends (yes, even bamboo and Tencel/lyocell) that are cool to the touch but absorb body heat and stay hot until they’re exposed to the air. Natural fibers are breathable and don’t absorb moisture or trap heat. 100% cotton in a low thread count percale weave is your most affordable option. Pair that with a light cotton blanket in a thin, open weave and you should be sleeping much cooler. Beyond fabric, there are electronic options that do actively cool you, like BedJet and Eight Sleep.

I’d go for egyptian cotton percale in a lowish threadcount Reason for percale is the weave isn’t as tight, so improves air flow. Reason for the lower threadcount (so 230-400) is they tend to be less thick Some people swear by pure linen for coolness. I’m not keen on the texture of linen personally, but if you like it / don’t mind the texture then you should maybe try that I’d stay away from sheets that claim to be cooling, unless they’re pure cotton (in which case it would be the weave / thickness of the fabric that is giving its ‘cooling’ properties). Blends of viscose and bamboo can sometimes be good for temperature regulation but personally , as a hot sleeper, I prefer pure, natural fabrics (viscose and bamboo are arguably semi-natural, in that they go through lots of processes that essentially makes them like manmade materials) More on reddit.com
