Description
OBJECTIVES:
Prior to Skylab, very little objective information had been obtained concerning the ability of man to sleep in space. Only by continuous EEG (electroencephalographic) monitoring can such information be obtained, and the technical problems associated with acquisition and analysis in space are significant. Before the advent of manned spaceflight, there was some concern about the possible adverse effects of this weightless environment upon sleep characteristics. During the Gemini program, however, it became apparent that fairly long duration space flight was not associated with drastic alterations of sleeping behavior. Astronauts could sleep in space and, on at least some occasions, did so fairly well. In the Gemini and Apollo programs, though, it became clear that in many instances insomnia was a problem. Sleep loss, while not absolute, was sufficient in some instances to result in performance decrements. In some instances, sleeping difficulties resulted in the use of hypnotic drugs to promote sleep and amphetamine-type medication to increase alertness following sleep loss
