This phrase is a simple command that recommends the person who hears or reads it to go into deep sleep for ten minutes. Deep sleep, as a type of non-REM sleep, is very beneficial for physical and mental health. Generally, deep sleep is very effective during the night for renewing energy, reducing fatigue, improving memory and concentration, strengthening the immune system, and reducing stress and anxiety. However, although ten minutes is known as a very short time for deep sleep, nevertheless, a short rest can still help improve physical and mental conditions.
