Objective To investigate the effects of short-term sleep deprivation(SD)at different time during night on serum cortisol level and emotion state of healthy men,and to find out the influence of work shift onto human circadian rhythm.Methods Two periods of sleep-time were deprived in the present study:the late-night SD(permitted to sleep from 0:00 to 3:00 each day)and the early-night SD(permitted to sleep from 3:00 to 6:00 each day).Ten healthy male adults were chosen to undergo the late-night SD first,followed by normal sleeping for eight nights for washout,and then underwent early-night SD.Each SD period lasted 6 days,i.e.1 day before SD,4 days of SD and 1 day after SD for recovery.Fasting blood samples,for detection of serum cortisol,were collected at 7:00 am every SD day,and the state anxiety inventory(S-AI)scoring was done at the same time.Results The cortisol levels were lowered after 2 types of SD(P0.05).Dependability analysis showed that the cortisol level during the late-night SD period was negatively related to the SD days(r=-0.954 7,P0.05).Both types of SD could elevate anxiety scores,which positively correlated with the SD days(late-night SD:r=0.990,P
