Summer and winter, the Japanese wear socks to sleep — here’s why!
Admit it: wearing socks to bed isn’t exactly appealing. We quickly picture a chilly grandmother or a less-than-glamorous look under the covers. Yet, in Japan, this habit is almost second nature… even in the middle of summer. What if this seemingly insignificant gesture were actually a valuable ally for better sleep—and, more broadly, for taking care of yourself every day? Sit back, relax, and let us explain.
Sleeping with socks on: a boost for falling asleep
Do you often have cold feet when you go to bed? This seemingly insignificant detail can disrupt your ability to fall asleep.
At night, our body temperature naturally drops by about 1 to 2°C. Metabolism slows down, circulation changes, and the extremities—especially the feet—cool down more quickly. As a result, it’s difficult to relax completely.
Wearing socks helps keep feet warm and sends a clear signal to the body: « It’s time to sleep. » Several studies have shown that keeping feet warm helps you fall asleep faster and promotes longer, more restful sleep.
In short, it’s a bit like dimming the lights before bed: you’re creating the ideal conditions. This simple trick promotes deeper and more restful sleep.
