Five Wellness Tips   In between your visits to our office, there are a lot of things you can do to keep your body - especially your back – healthy. If this sounds familiar-well, we've been talking to your mother. Just so happens she was right: Sit up straight. Develop the habit of good posture. It makes a world of difference in the way your back feels. Eat your vegetables. A good diet is important to your overall health-all those nutrients help your body repair itself. And, you want to keep your weight down.  Carrying extra weight puts extra strain on the back. Turn off the TV. Get up and move.  Go for a walk. Add exercise to your regular routine. And when you have to sit for long periods, stretch regularly. Put that down. Don't lift things that are too heavy for you. (And if you have to, you know what they say-lift with your legs, not your back.) Don't carry around a backpack stuffed full of books (especially not on one shoulder) or a heavy bag if you can avoid it. The key is to minimize. Only take what you really need. Go to sleep. Sleep is essential for your wellbeing. Just don't sleep on your stomach, which can strain the muscles in your neck and back. Practice sleeping on your side or back.
