　　There is a saying in the West that you are what you eat (a person means that he can reflect what he eats, that is, his personality and living environment). This sentence changes as follows: Sleep reflects your eating habits and may be more appropriate. At a recent international conference, SLEEP 2016, a study by the Perelman School of Medicine at the University of Pennsylvania showed that an individual's body composition and calorie intake affect the duration of each sleep stage.

　　In this study, 36 healthy adults slept continuously for 10 hours every night. The researchers used a multi-channel sleep recorder to record the physiological changes of these participants during their sleep the next night. The researchers analyzed the resting body composition and energy expenditure of these participants in the morning after the first night of sleep. The researchers also assessed the participants' daily diet.

　　The research team found that resting body mass index (BMI), body fat mass and energy expenditure are not important predictors of sleep time. Rapid eye movement sleep (rapid eye movement, REM) has a high speed. EM is usually a dream stage. Compared with the non-REM stage, people in this stage have faster heart rate and breathing.

　　The research team also found that increasing protein intake can reduce the duration of the second stage of sleep. At this stage, people's heart rate and weight are normal, but their body temperature drops slightly.
