You’ve likely experienced it: a sweltering night, fan on full blast, and still—you reach for your blanket. It might seem illogical, even uncomfortable, but the moment that blanket wraps around you, your body relaxes, and sleep feels within reach.
So why do we cling to our blankets, even when the temperature rises? As it turns out, there’s real science behind this comforting habit—and once you understand it, it all makes perfect sense.
1. Blankets Help Regulate Body Temperature
Humans are warm-blooded, which means we regulate our internal temperature automatically. But while we sleep, that regulation becomes less active. During deeper stages of sleep, the body struggles more to maintain its ideal temperature—especially when the surrounding environment fluctuates.
That’s where blankets come in. They help create thermal stability, acting as an insulating layer that helps keep your body temperature consistent throughout the night.
