1. SAFE LIFTING

2. Your Spine
The human spine (or backbone) is made up of small bones called vertebrae.
The vertebrae are stacked on top of each other to form a column. Between each vertebra is a cushion known as a disc. The vertebrae are held together by ligaments; muscles are attached to the vertebrae by bands of tissue called tendons.
The lower part of the back holds most of the body’s weight. Even a minor problem with the bones, muscles, ligaments, or tendons in this area can cause pain when a person stands, bends, or moves around. Less often, a problem with a disc can pinch or irritate a nerve from the spinal cord, causing pain that runs down the leg below the knee, called sciatica. Every time you bend or move, these discs compress with the motion of the spine.

3. Types of Injuries
Every time you bend over, lift a heavy object, or sit leaning forward, you put stress on the components of your back and spine. Over time, they can start to wear out and become damaged.
Many of the problems that cause back pain are the result of injury and degeneration of the intervertebral disc. Degeneration is a process where wear and tear causes deterioration, like when your favorite jeans get old. The disc is subjected to different types of stress as we use our backs each day.
Eventually, discs can collapse or herniate; vertebrae can shift; bone spurs can develop.
Acute or immediate injuries to the back can be caused by tearing or straining ligaments and muscles. Muscles can also spasm due to stress or tension.

4. Trivia Which are generally recommended as the best sleeping positions?
A. On your stomach or back (with legs level)
B. On your side (w/ knees slightly bent) or back (w/ pillow under knees)
If you’ve been waking up with a sore or painful back, you might try sleeping on your side with your knees slightly bent, or on your back with a small pillow under your knees. If that doesn’t work, you might wish to try a new mattress, or put boards under your old mattress to firm it up. Of course, it is always wise to check with you physician about any sort of health problem.
