Homework. School can be a pain in the neck, figuratively. But if school is literally
causing problems for your neck or back, your backpack may be to blame.
Believe it or not, overloaded and poorly-positioned backpacks can actually
cause serious injury. In a 2004 study published in the Journal of Pediatric Orthopedics,
64% of 11- to 15-year-olds who used backpacks also complained of pain.
If you’ve ever had back or neck pain, you know how uncomfortable it can be.
The pain is often caused by pressure on the disks of the vertebrae. These
disks are responsible for spacing out the vertebrae, holding them in place,
and acting as shock absorbers. As you get older, your disks wear down or
degenerate, causing chronic pain, herniated disks, and nerve damage. Putting
pressure (like the added weight of a heavy backpack) on these disks wears
them down even faster.
So what’s a student to do? The stuff inside that pack is essential to
survival (or at least to passing math), but you don’t want to pay a painful
price in years to come. Fortunately, following a few simple rules can ensure
that you’re using your backpack properly and safely.
-
Choose
the right sized pack.
Adult-sized backpacks are made for adults, not children. Make sure to buy a
pack that is appropriate for your body size. Most stores and catalogs list
this information in the product description.
If not, just ask. A general rule of thumb is that when the shoulder straps
are adjusted so that they are snug, the bottom of the backpack should be
about two inches above your waist.
-
Lighten
your load. Your filled backpack
should weigh no more than 15% of your body weight. (Multiply your weight in
by .15 to get the maximum weight you should carry.) A 140 pound person should
carry no more than 21 pounds, and an 80 pound child should keep it under 12
pounds. To lighten the load, first remove any non-essentials. Even an extra
hairbrush and a few notebooks can add
weight. If your bag is too heavy, even when pared down to the basics, remove
a textbook and carry it in your arms.
-
Lift
with your legs. To lift and put on
your backpack properly: face the pack, bending at your knees—not your
waist—then lift with your legs and apply one shoulder strap and then the
other.
-
Position
your pack properly. Wearing
your backpack on one shoulder can cause muscle strain and imbalance. Wear
both shoulder straps, and adjust them so that they are comfortably snug. If
the backpack has a waist strap, use it. It will distribute the weight of the
pack more evenly. And position your body properly too, by maintaining good
posture while you’re wearing your pack (and even when you aren’t!).
-
Get
and stay fit. Maintaining your
overall fitness by exercising and staying active can increase your strength
and ability to carry heavy backpack loads, which will reduce your chance of
injury. Cardio, strength training and flexibility are essential to your
health and fitness.
-
Set
a time limit. Try to wear your
backpack for 30 minutes or less. Unless you’re on an all-day hike or jaunting
across a sprawling campus, this rule shouldn’t be hard to follow. If you’re
stuck wearing it for longer periods, try to carry the lightest load possible,
and try to follow all of the other rules to a “T.”
