For those who sleep with socks, you should know this

Wearing socks to bed is more than just a cozy habit—it may actually provide a range of real sleep benefits. While some people think of bedtime socks as purely a matter of comfort, research shows that warming your feet at night can influence your body’s ability to fall asleep, stay asleep, and even improve the overall quality of your rest. This seemingly small choice is connected to the way our bodies naturally regulate temperature as we transition from wakefulness to sleep.

When your feet are warm, blood vessels in the skin expand through a process called vasodilation. This widening of the blood vessels increases circulation to the extremities and helps release heat from the body’s core. Lowering the core body temperature is a key signal to the brain that it is time to sleep. Essentially, by pulling heat away from the center of the body, warm feet encourage the brain to trigger feelings of drowsiness and allow you to drift off more quickly. Studies suggest that people who warm their feet—whether through socks, warm water, or heated blankets—tend to fall asleep faster and experience fewer nighttime awakenings. In this way, socks can be considered a simple, non-invasive tool for supporting better sleep hygiene.
