Wearing socks to bed is more than just a cozy habit—it may offer real sleep benefits. Research suggests that warm feet can help you fall asleep faster and stay asleep longer by supporting your body’s natural temperature regulation.
When your feet are warm, blood vessels expand through a process called vasodilation. This helps lower your core body temperature, which signals to your brain that it’s time to sleep. As a result, you may drift off more quickly and enjoy deeper rest.
In addition to sleep support, socks worn overnight can help retain moisture, keeping the skin on your feet soft and hydrated. For some people, this added warmth may also reduce anxiety or help manage nighttime symptoms like hot flashes.
However, sleeping in socks isn’t ideal for everyone. Those with certain health conditions—such as diabetes, poor circulation, or fungal infections—may be advised to avoid it. Similarly, individuals who experience night sweats or have sensitive skin might find socks uncomfortable or irritating during sleep.
It’s also not recommended for infants or toddlers to sleep in socks, as their temperature regulation differs from that of adults. For them, other methods of keeping warm are usually safer and more effective.
If you choose to wear socks to bed, opt for clean, breathable materials like cotton or moisture-wicking fabrics. Avoid tight, synthetic, or compression socks unless prescribed by a healthcare provider. Making the right choice can help you stay comfortable and support healthy sleep.
