Wearing socks can promote blood circulation in the feet, raising their temperature. An increase in body temperature helps relax the body, allowing people to fall asleep faster.
During sleep, the body's core temperature naturally drops. Wearing socks can help the body reach this state faster. When the feet are warm, the body will dilate blood vessels to dissipate heat, speeding up the drop in core temperature and promoting sleep.
Cold feet can cause awakenings during the night. Wearing socks can reduce the occurrence of this. Keeping the feet warm helps improve the continuity and quality of sleep.
Wearing socks to sleep can help extend the duration of sleep. Studies have shown that adopting this simple habit can result in an average of 32 more minutes of sleep per night. This is an extremely effective method for promoting sleep, especially for those who frequently suffer from insomnia or tend to wake up early.
