Sleep on a Proper Mattress
If you feel you’re “sleeping wrong,” or if you’re stiff and achy when you get up in the morning, the problem is probably musculoskeletal and relatively easy to deal with. I recommend doing a few forward bends and whole-body stretches before going to bed for the night. If that doesn’t help, a harder mattress or futon might be the answer. A mattress that is neither too soft nor too hard prevents the body from arching or sinking and preserves good standing posture when you’re lying down. Some people swear by Tempur-Pedic and memory foam. Studies have not found convincing evidence for recommending any specific type of mattress for the prevention of low back pain, but a medium-hard mattress may be better than a hard one. One thing is for sure: replace a mattress that is more than 10 years old.
