How to choose the best sleeping position for you, according to the experts

A key part of the nightly bedtime routine is getting comfortable in a certain sleeping position — but how do you know which one is best?

A majority of American adults (69%) sleep on their side, according to a recent poll. That is followed by those who sleep on their backs (19%) and their stomachs (12%).

Sleep expert Wendy Troxel, PhD – a RAND Corporation senior behavioral specialist and licensed clinical psychologist in Utah – said that sleeping positions are "highly subjective" to each individual.
