Why can't I soak my feet after ten o'clock

After 10 o'clock, it is not recommended to soak feet mainly because of the consideration of the biological clock and circadian rhythm of the human body.

After 10 o'clock at night, the human body gradually enters a state of rest and preparation for sleep. At this time, soaking feet, especially using water with too high water temperature, may stimulate acupoints and nerves in the feet, causing nerve excitement,

which is not conducive to sleep.
