What's the Best Position to Sleep In?
As with the mattress you chose, the position you sleep in is based on your personal preference or physical limitations based on pain or restrictions from your doctor because of surgery. In general, back sleeping is the most stable position for your spine and the least irritating to your muscles. Side sleeping is the next best. Stomach sleep is the least desirable if your back is not adequately supported.
I personally like a modified side-lying position, using full-length body pillow. I sleep "hugging" the pillow with my arms and legs, which is really comfortable and takes pressure off my lower back. You should try it. Body pillows can be found at most retail bedding stores. They are not expensive and may give you an alternative sleeping position that will make a big difference in your comfort level, thus improving the quality and duration of sleep.
