SLEEP AND ALTERED PROPRIOCEPTIVE INPUT AS RELATED TO WEIGHTLESSNESS: WATER IMMERSION STUDIES

Abstract

The 'free-floating' condition of immersion is ASSOCIATED WITH SUBSTANTIAL ALTERATIONS IN MECHANORECEPTIVE FEEDBACK TO THE CENTRAL NERVOUS SYSTEM IN A MANNER SIMILAR TO THE FREE-FLOATING CONDITION OF WEIGHTLESSNESS. O NE AREA HAVING RATHER IMMEDIATE OPERATIONAL APPLICATION CONCERNS SLEEP UNDER THESE CONDITIONS. Electroencephalographic and electrooculographic recordings were made during sleep of completely immersed, neutrally buoyant subjects. Sleep records were obtained while using tether and clamshell sleeping facilities and were compared to each subject's normal bedrest sleep records and subjective impressions. The results are presented and their possible application to prolonged weightlessness is discussed.
