To investigate the frequency of ‘rolling over’ in bed and to clarify sleeping posture characteristics in nocturnal sleep, the sleeping positions of 19 healthy men were videotaped over 7 h (0:00–7:00 hours) for two consecutive nights. Sleeping habits and the degree of satisfaction upon awakening were also surveyed by using questionnaires. A significant positive correlation (r = 0.60, P < 0.01) was observed between the most favorite hypnogenetic position of the body and the most frequently observed position of the head during nocturnal sleep. Furthermore, sleeping positions varied from individual to individual, and the same subject slept showing similar positions and roll over frequencies to those on the day before.
