| Abstract |
The objective of this project was to examine physiological variables in relationship to sleep motor activity, subjective sleep quality, mood and complaints during confinement. Six male and two female subjects spent seven days in an isolation chamber simulating the interior of the Japanese Experimental Module. Each 24h period included 6h of sleep, three meals and 20min of exercise. Each morning, subjects completed questionnaires on the quality of their sleep. Catecholamine and creatinine excretion, urine volume and body weight were measured two days before and after confinement and sleep motor activity was recorded during confinement. Confinement produced no significant change in body weight, urine volume or questionnaire results. In contrast, epinephrine, norepinephrine and sleep motor activity showed significant differences during confinement. Higher nocturnal norepinephrine excretion correlated with higher sleep motor activity. |
