A report on current research by Dr. Ian Oswald, Department of Psychiatry, University of Edinburgh

We sleep for nearly a third of our lives. Why? Scientists, despite much research, still cannot tell us. But they do know a great deal about what is going on during sleep: about sleep in pregnant women, about psycho-physiological rhythms and dreams in men; about the effect of environment on duration and the endlessly debated assertion 'I need my eight hours.' Dr. Oswald presents a research report illustrated by: Dr. Irwin Feinberg, New York; Dr. Charles Fisher, New York; Dr. David Foulkes, Laramie, Wyoming; Dr. Stuart Lewis, Edinburgh; Professor J.N. Mills, Manchester; Dr. O. Petre-Quadens, Antwerp; Dr. Betty Schwartz, Paris; Dr. G.S. Tune, Liverpool
