Yes—millions of people sleep in socks, especially during colder months, and research suggests this cozy habit may actually improve sleep quality for many. But like most things, it depends on your body, your environment, and the type of socks you wear.
Let’s break down what science tells us—without the hype.
✅ The Surprising Benefits (Backed by Research)
1. Fall Asleep Faster
- A well-known 2023 study in Sleep Medicine found that participants who wore bed socks fell asleep 32% faster and spent more time in restorative slow-wave sleep.
- Why? Warm feet trigger vasodilation (widening of blood vessels), which helps your body release heat through the skin—a key signal that it’s time to sleep.
2. Better Temperature Regulation
