Sitting hunched over your computer at work or over the steering wheel in your car puts stress on your spine and the muscles between the shoulder blades. This can cause back or neck pain, or exacerbate it if you already have it, says Dr. Gross. Poor body posture also has been linked with headaches, jaw pain and other forms of chronic or recurring pain.

Solution: If you work at a computer, sit with your upper back against a firm, supportive chair, a hollow in your low back and your thighs parallel to the floor. Make sure your computer screen is at eye level and situated so your head stays in a neutral position (not tilted, turned or flexed). Be sure to “get up and move around every 30 minutes,” suggests Dr. Gross. “Our bodies are not meant to be in any one position for too long.”
