Abstract
INTRODUCTION
I. RELATION BETWEEN CIRCADIAN RHYTHM AND FETAL BACK POSITION
Circadian rhythms are biological processes that follow a roughly 24-hour cycle, influenced primarily by light and darkness in the environment. These rhythms are crucial for regulating various physiological functions, including hormone secretion, sleep-wake cycles, and even fetal development. The relationship between circadian rhythms and fetal back position is an emerging area of research that highlights how maternal circadian signals may influence fetal positioning during pregnancy.

• Maternal Circadian Rhythms and Hormonal Influence
The maternal circadian system plays a significant role in regulating hormonal profiles throughout pregnancy. Hormones such as melatonin and cortisol exhibit daily fluctuations that can affect fetal development. Melatonin, which is secreted in higher amounts during the night, has been shown to influence fetal growth and development. This hormone can cross the placental barrier, potentially affecting the fetus’s own circadian rhythms.
Research indicates that the synchronization of maternal and fetal circadian rhythms may impact various aspects of fetal positioning. For instance, certain positions may be favored at specific times of day when maternal hormone levels are optimal for promoting movement or growth in the fetus.
