Sleeping on your back is an excellent way to reduce pressure on the spine and allow for good spinal alignment. Try to sleep on your back supported by pillows for the optimal position. Sleeping in a fetal position or leaning on uncomfortable pillows and chairs can cause stress on the lower back. Get a comfortable mattress with enough support for your shoulders to be at the same level as your hips. Remove all tight clothing or belts that can pull on the spine, especially when sleeping or sitting for extended periods.
