Impaired sleep quality is very common among pregnant women. Research shows that it has many negative consequences. The aim of the study was to assess the quality of sleep of pregnant women in each trimester in comparison to non-pregnant women.

Material and methods:
65 pregnant women and 67 women from a control group participated in an anonymous study. The criteria for inclusion were: 18–35 years of age, lack of recognized and treated mental and chronic disorders, not working in a shift/night shift system. For the study group the additional criterion was a normal pregnancy. The employed tools were: a questionnaire (demographic data, course of pregnancy), scales: Sleep Quality Scale, Epworth Sleepiness Scale, actigraphy.

The pregnant women slept more than an hour longer than the control group, however, their sleep quality was worse and daytime sleepiness was more intense. Over 58% of the pregnant women noticed a reduction in their sleep quality compared to the pre-pregnancy state. The factors connected with low sleep quality were: sleep position, night calf cramps, the need to go to the toilet at night, stress, night awakening.

Most pregnant women experience a reduction in sleep quality during pregnancy. In more than 43% of woman reduced quality of sleep was observed and almost 1/3 had a significant increase in daytime sleepiness. Considering the negative effects for both women and children, it would be advisable to pay attention to the problems of impaired sleep quality: education, early screening diagnostics and sleep hygiene. Such a holistic approach may help improve sleep quality in pregnant women.
