Many individuals switch between different postures during the course of one night, and they may also alter their preferred positions across various stages of life, explains Harris.
Changing habits can be difficult, but you can teach yourself to sleep in a different position. As Harris points out, "Most people eventually adapt, though it does take some time to become accustomed to it."

Sideways versus back versus stomach sleeping
Lying on your side or back is typically viewed as more beneficial for your health compared to sleeping on your stomach, which can lead to various issues like back pain. "In the field of sleep medicine, we often favor side-sleeping," explains Augelli.
As mentioned, sleeping on your back or side might worsen specific health issues; for instance, acid reflux could become more severe when lying on your back, and shoulder troubles might intensify when you're on your side. Conversely, some individuals suffering from sleep apnea might find relief by sleeping face down.
