9. DO NOT SMOKE: Smoking is the fastest way to ruin your spine. According to a study reported in Spine 2004, spinal discs can degenerate very rapidly in smokers. A smoker's spine does not heal quickly after an injury or surgery if at all. In fact, if you quit smoking now, you will probably have less pain later.
10. Watch Your Weight: You may not realize that your body weight affects your neck. Sure it does. Your arms get heavier and your breasts get heavier as you gain weight. Furthermore, your shoulder blades spread apart as you gain weight also. All of these changes in an obese body increase your likelihood of developing neck pain.
Exercise Tip: One of the most important exercises for preventing neck pain is rowing.
