I have researched the best cooling sheets for the past few days because I’m a hot sleeper and really need something to stay cool and comfortable at night, especially during the summer. I read reviews on The New York Times, Consumer Reports, and Good Housekeeping, and these two options are ... More on forum.mattressunderground.com

If you sleep hot, you don’t actually want “cool to the touch” bc thats a marketing term indicating they ONLY start off cool. For OP (or others reading this), unfortunately, the best way to have temperature regulation (staying cool) is to convert as much as your bedding as possible to natural materials. Including your mattress- memory foam is essentially a furnace, as is the polyester most people have in most of their bedding. In lieu of replacing a memory foam mattress, try a wool topper. Do your own research (including buying a returnable one), to see that wool is the best material for temp regulation and staying cool through the night. I’m not connected to Big Wool, promise!

It sounds like you might have more of a problem than just the sheets. What sort of mattress do you have? I know you say you're on a budget but the best advice I can give is never go cheap on anything that your nights sleep depends on. As a nuclear furnace sleeper myself the only solution I eventually found was to use a Dunlop latex mattress topper - they're full of holes and micro pores that basically let the air flow underneath you instead of allowing heat to build up. Stick a 100% cotton sheet on top and that's as cool as it gets imo. It's not a cheap fix (a 2" latex topper will set you back at least a couple hundred bucks even without a cover) but it's worth it.

You will get a lot of different answers here, but I will always maintain that quality Linen sheets are the best at regulating body temperature. No matter what is suggested here, avoid high thread count cotton/sateen materials as they do not breath well, which you need for temperature regulation. Linen can absorb far more moisture from your body than cotton, bamboo or most other materials, which in the end is what you want. Other materials feel cool initially, but as you perspire over night they will become clingy. My wife and I have tried a lot of materials and after getting good Linen sheets, we will never go back. They are pricy, but you spend 1/3 of your life in bed. They also work well in the winter for the same reasons. They will also last for decades, unlike most other fabrics. More on reddit.com
