System Organization of the Relationship Between Emotional Stress and Sleep Yumatov EA and Pertsov SS

Here we review an urgent medico-social problem exists, which integrates the social environment, psychoemotional state of people, and sleep disorders. A close interrelation exists between the human psycho-emotional state and sleep. Emotional stress is followed by sleep disorders, while sleep deficiency increases the severity of stress. Experimental data illustrate the mechanisms for a relationship between emotional stress and sleep at various levels of organization, including the structuraland-neurophysiological, neurochemical, and somatic-andautonomic levels. The results of studies performed by Russian and foreign researchers allowed us to make the principal conclusions on a relationship between the emotional state and sleep. These data show the existence of common neurophysiological mechanisms and antagonistic relations of neurochemical processes in emotional stress and sleep.
