You have probably done it without even noticing—sliding one foot out from under the blanket to cool off at night. But this familiar sleep habit is not just a random comfort trick. Research suggests it can be one of the easiest and most effective ways to help your body settle into sleep more quickly and smoothly.

So why does the “one foot out” method work so well? The explanation comes down to how the body naturally manages temperature before sleep—and how your feet are especially suited to help regulate that process.

Heat, feet, and sleep

As night approaches, your body prepares for rest by gradually lowering its core temperature, a key part of the circadian rhythm. Sleep experts say this internal cooling is important for initiating deep, restorative sleep.

“The drop in temperature starts about two hours before you go to sleep, coinciding with the release of the sleep hormone melatonin,” explains the Sleep Foundation. “During sleep, body temperature continues to fall, reaching a low point in the early morning and then gradually warming up as the morning progresses.”

As this cooling begins, your body shifts warm blood away from the core and toward the surface—especially to the hands and feet. When those areas are exposed to cooler air, they function like natural vents, releasing heat and helping the body transition into sleep mode more efficiently.
