[Current state of space biorhythm study].

The paper presents a review of the literature covering a new branch of science--space biorhythmology--that evolved in the 1960s. The paper surveys briefly publications on general biorhythmology that formed the basis for the new branch of science. The paper discusses specifically the investigations that formulated the basic concepts of space biorhythmology in theory and practice. It describes the problem of desynchronosis as one of the most important problems and outlines its involvement in the general adaptation syndrome as a necessary component. The paper gives a scheme of measures developed in the USSR with the purpose of preventing desynchronosis and stresses the advantages of further study of space biorhythmology.
