Backpacks - What are the facts?

It seems as though more and more students are using backpacks to carry their books, food, sporting gear, and any other items they may need throughout the school day. Using a backpack is an excellent way to tote these items; however, if the backpack is too heavy or improperly worn, it can lead to injuries to the back and shoulders.

A backpack may be the best choice for carrying school items, especially compared to a briefcase or shoulder bag. If the backpack is properly worn, it is supported by the body’s strongest muscles. These muscles stabilize the body and keep it in good alignment, and are best used for carrying heavy loads. They are stronger and have better endurance than the muscles in the arms.

If the backpack is improperly worn, it can cause chronic pain and bad posture in students, especially those who are still growing.

Perhaps the pictures and descriptions here will help you wear your backpack properly, and avoid injury.

Backpack Properly WornBackpack Safety

 

Is it Necessary to Wear Both Straps?
Wearing a backpack on one shoulder can cause a person to lean to one side in order to handle the uneven weight. Over time, this can cause excessive stress on upper and lower back, neck and shoulders. Teenage girls are especially at risk for scoliosis.

How Much Should a Backpack Weigh?
Students seem to be carrying heavier loads. Books, after school clothing, and laptops are heavy contents. Even when worn properly with both straps, leaning forward to compensate for the weight can affect the natural curve of the spine. A good rule to follow is keep the weight of the backpack at 15% to 20% (or less) of the person’s body weight.

What is the Best Style or Type of Backpack?
Make sure the backpack has wide straps. Narrow straps can be painful on the shoulders and press on nerves and blood vessels. Backpacks with waist belts are preferred. This helps to distribute the weight of the backpack more evenly. Backpacks with only one strap are not recommended. The weight of the backpack when empty is also to be considered. For example, canvas is lighter than leather.
