When your child acts as if he or she is carrying the weight of the world on her shoulders, maybe you should check their backpack. Overloaded or poor-fitting backpacks can be harmful.
Children can hurt themselves by using poor postures—arching the back, bending forward, twisting, or leaning to one side—while hefting a heavy backpack. Such postures can skew the spine’s alignment so its disks can’t absorb shocks as they should.
Overloaded backpacks also place stress on muscles and soft tissues. That causes fatigue and strain, increasing the risk of neck, shoulder, and back injuries and even nerve damage.
Experts offer these tips for parents and children:
Pick a lightweight backpack with two wide, padded shoulder straps, a padded back, and a waist strap, which can help spread the load.
Use both straps to spread the weight and promote good posture. Using one strap means one side of the body bears most of the weight.
Take care when putting on and taking off backpacks. Avoid twisting too much. When bending to pick up a heavy backpack, bend with both knees, not at the waist.
Position the backpack evenly in the middle of the back, near the body’s center of gravity. The backpack should sit 2 inches above the waist.
Adjust the shoulder straps so the backpack can be put on and taken off with no trouble. The straps should permit free arm movement without being too loose.
Limit the load to a maximum of 10 to 20 percent or less of the child’s body weight.
Load the heaviest items closest to the child’s back. Use all the compartments to spread the weight.
Make frequent school locker stops to remove items that aren’t needed right away.
Remember that rolling backpacks must be carried up stairs.
