Examines some of the significances of circadian rhythms: depression, jet lag and increased accident-proneness on night shift. Follows a case in which severe winter depression is successfully relieved by light treatments which seem to have the effect of putting the hypothalamus on a summer schedule. Shows the internal rhythms evident in sleep patterns using a computerized brain scan whose image on the screen resembles waves on a beach. Reviews what was learned from a long experiment of living underground, from the removal of a brain tumor in a violent patient and from an injury caused by an auto accident resulting in hormonal imbalance and impotence.
