8 everyday habits that could be damaging your posture

Sleeping incorrectly

If you get up with a sore back, or are getting one for no reason, pay attention to sleeping posture and the sleeping surface. Incorrect sleeping puts undue stress on the spine and all muscle groups alongside it.
Correct it: Use a firm mattress that doesn’t give under bodyweight. Flip and rotate it periodically. If sleeping sideways, use a small pillow to support the curve of the neck and one between the legs to help maintain alignment. If lying on your back, a thin pillow below the knees helps similarly.
