[Work and rest organization for the cosmonauts on a long flight].
Proper arrangement of work-rest cycles of crewmembers in long-duration space flight is a practically important task of space ergonomics, a field of science studying man's work capacity and methods of its increase. The basic principle of space ergonomics assuring high efficiency of space crewmembers is to cover every aspect of their activities. Of particular importance is the use of laws of biorhythmology, in order to select candidates least susceptible to desynchronosis and closely resembling each other in their biorhythmological status. At the present time, work-rest cycles in a prolonged space flight should be arranged on a 24-hour basis with a normal day-night alternation, including 8-hour night sleep and 2-hour day rest. Optimization of cosmonauts' activities in space demands that they strictly adhere to the recommended work-rest cycle; this can be achieved through their highly motivated desire only.
