Abstract: Dark deprivation is a process in which there is a complete or partial exclusion of the dark phase of the day in an individual. In the modern world, this is not an uncommon phenomenon, as people surround themselves with light sources in the form of lighting devices, monitors, and gadgets. There are also certain types of work that involve almost constant presence among artificial light sources: office, shift work. Pregnant women can also be involved in these kinds of work. With such exposure there is a violation of circadian rhythms – the internal watch of the body, responsible for the control of synthetic, regulatory processes within the individual, regarding the length of the day. At the moment, there are no studies that contain the results of research on the effect of dark chronodestruction on the development of pregnancy. There are no data on characterization of embryotoxic effect of dark deprivation on postnatal development of posterity. It has been proven for the first time that dark deprivation leads to a significant decrease in the weight of females during pregnancy as well as in the offspring born to them in the experimental group compared to the control indicators by 1.33-1.6 times. The effect of dark deprivation leads to a significant change in the number of offspring in the experimental group towards a decrease compared to the controls and retards their physiological maturation, which is characterized by a later appearance of morphological traits in the offspring of the experimental group.
