Abstract: | Sleep disturbances are frequent during pregnancy and are currently regarded as one of the most important factors determining pregnancy outcome. Detailed research of sleep features during pregnancy is obviously essential. In the present review recent data concerning changes in sleep structure and regulation in pregnant women and rats - main subjects of experimental sleep research, are given, including surmised mechanisms underlying such changes. The importance of women's sleep integrity preservation during pregnancy for the viability and normal development of the fetus is emphasized and possible ways of pathological influence of sleep disorders during this period are discussed. |
