The nurses’ body temperature, heart rate, blood pressure, electrocardiogram R-R interval fluctuation, serum catecholamines, cortisol concentrations and subjective fatigue were measured respectively on day shift, mid-shift shift and night shift shift. In addition, the average heart rate, number of steps, energy expenditure, and excretion of urinary catecholamines were measured within eight hours of their class work day. The results are as follows: ① In addition to night shift
