If you sleep warm, you’ve probably already tried the obvious fixes. You drop the temperature, swap blankets, try a “cooling” pillowcase, and still end up waking up a little too hot. In a lot of cases, the easiest win is the layer that’s touching you the whole time: your sheets. They decide how much air can move around your body and whether moisture sits on the surface or gets pulled away. When sheets breathe well, the bed feels less sticky, and you don’t have to keep shifting to get comfortable.
