7.Sit Too Long
It stresses your back muscles, neck, and spine. Slouching makes it worse. Sit straight in a chair that supports your back, and set the height so your feet rest naturally on the floor. But no matter how comfortable you get, your back won’t like sitting for long stretches. Get up and move around for a couple of minutes every half hour to give your body a break.
8.Overeat
Extra pounds can strain the bones and muscles in your back, especially if you gain weight quickly. Eat slowly so that your body has a chance to let you know it’s full. Pick nutrition-packed munchies and meals so you feel satisfied with fewer calories. So if you snack on cheese or chips, try eating some veggies and plain yogurt instead.
