Some people suffer back pain because they sleep in a bad position, or because their mattress is too soft or does not provide enough support. Question: What is the best sleeping positions for your back? Your Side, Your Back, Your Stomach? Answer: On your side [with knees slightly bent] or on your back [with a pillow under your knees].
If you’ve been waking up with a sore back, try these sleeping positions. If that doesn’t work, you might try a new mattress or put boards under your old mattress to firm it up. Of course, it is always wise to check with your physician about any sort of health problem.
