Anyone who’s spent a night shivering under a too-thin blanket or sweating in an oppressively warm room knows: Getting temperature right is key to a great night’s rest. This finickiness isn’t just about comfort\u2014it’s basic sleep science. An initial drop in body temperature signals the onset of sleep and helps you feel drowsy. As the night goes on, getting either too hot or too cold can interrupt REM sleep<\/a> and brain-refreshing slow-wave slumber<\/a>. In fact, research<\/a> shows temperature is one of the most important<\/em> variables in how solid and restorative your sleep is.<\/p>\n\n\n\n

How you set your thermostat is part of the equation (the National Sleep Foundation recommends 60 to 67 degrees Fahrenheit), as is whether or not you have a partner adding body heat to the mix<\/a>. But one of the most critical variables is the surface you’re sleeping on.<\/p>\n\n\n\n

\u201cYou’re more likely to sleep warm on a foam mattress, even when compared to a hybrid innerspring, which we define as a combination of foam layers over metal springs,” according to Chris Regan, chief mattresses tester for Consumer Reports<\/em><\/a>. “Sleeping hot” has long been one of the chief concerns about memory foam. By design, memory foam responds to temperature, softening as it warms and molding to the sleeper’s unique curves. That distinctive contouring ability is what many people love about memory foam, but it can also trap and retain heat close to the body.<\/p>\n<\/div>\n\n\n\n
