What is the best position to sleep in?

Side lying with knees slightly bent tends to be the best position to sleep in for most conditions; however, it is important to make sure that the neck is well supported by having a correct pillow height. The head should remain in a straight line to the rest of your spine. Side lying, however, may irritate existing shoulder problems, in which case lying on your back may be more appropriate. Hip and pelvic problems may be strained when side lying, and many patients find it helps to place a pillow between the thighs as this reduces torsion through the pelvis. Sleeping on your front is generally not good as it causes your head to be rotated, causing strain to the joints in your neck. If you also use a pillow, your neck will be rotated (bent backwards) which can aggrevate neck problems. Lying on your stomach may also lead to lower back sagging-so increasingly concave bend (the lordosis) which can also result in low backache.
