Sleeping is paramount and you should consider several aspects to help your sleep. One big one is positioning. The approach we take to positioning is to find out what position you feel most comfortable in and then support your body with pillows so there is reduced tension on your body. This unloading effect can afford you more restful time. Back sleeping: Lay on your back and place a pillow under your tailbone so that your tailbone is lifted up on to the pillow. Ideally, a second pillow would be placed from knees to ankles, overlapping the first pillow slightly at your knees. The pillow at your head should, if possible, come up under your neck and fill the space under your neck. Grab the bottom corners of the pillow and pull them up toward the ceiling to do this. You don't need a thick pillow for this. A nice moldable pillow is great because it can fill the nooks and crannies. Side sleeping: A pillow between your knees that goes all the way to your feet is wonderful. A pillow that is vertical that you can tuck under your armpit so your top arm is unloaded will help your shoulders relax. If you have some low back or hip discomfort in this position still, add a scrunched up small blanket or towel under the smallest part of your waist to help support your spine. Stomach sleeping: This isn't a favored position for practitioners to allow sleepers to do. This is due mostly to people who want to lay on their stomach and turn their head to the side up on a pillow. This is hard on the neck and the vasculature up high in the neck/head. If you can do a sort of hybrid position like the picture but filling the gaps with pillows, than this can be a nice compromise.
