Sleep position

A sleep position is the body configuration assumed by a person during or prior to sleeping.

The topic of sleep position has been covered throughout history and has produced a variety of studies, research papers, books, etc. The general consensus is that depending on a multitude of factors such as age and physical as well as mental wellness, someone's sleep position can pose positive or negative effects. Extensive research has been done through tracking sleep clinically as well as surveying the general population. From the data, scientists have proposed several "optimal" and "sub-optimal" sleep positions depending on said persons mental or physical issues. The most researched and mentioned sleep positions are the lateral (side sleeping, often in a fetal or semi-fetal configuration), supine (faced upwards), and prone (faced downwards) positions, as those positions come naturally when trying to sleep.
