Stomach sleeping can feel comfortable for some people, but it may place extra strain on the neck because your head usually has to remain turned to one side.
If you wake up with frequent neck or back discomfort, changing your sleeping position—or adjusting your pillow—may be worth trying.
So, which side should you sleep on?
There isn't one sleeping position that doctors universally recommend for every person.
If you are generally healthy and sleeping comfortably, there's usually no need to panic about which side you're on.
But if you experience frequent nighttime reflux, loud snoring, breathing interruptions, pregnancy-related discomfort, or persistent pain, your sleeping position may be worth discussing with a healthcare professional.
Sometimes, the smallest nighttime habit can affect how you feel the next morning.
And your favorite side of the bed may be more important than you ever realized.
