The
vertebral column consists of 33 bones called vertebrae, and between the
vertebrae are discs that act as natural shock absorbers. When you place a large
weight incorrectly on your shoulders, such as a PU
leather backpack full of books and other objects, the weight can pull
you back. To compensate, it is possible that you bend forward to the height of
the hips or that you bend your back; This can cause the spine to be compressed
in an unnatural way.
Teenagers
who carry heavy backpacks sometimes also compensate for extra weight by leaning
forward; Over time, this situation can cause the shoulders to be rounded and
the upper part of the back to bend. Due to the great weight, there is the
possibility that you develop shoulder with women
canvas backpacks, neck and back pain.
If you use
the backpack only on one shoulder or if you carry the books in a messenger bag,
you may end up tilting to one side to compensate for the extra weight. You may
develop pain in the upper and lower back, and distend your shoulders and neck.
Improper use of the backpack can lead to poor posture.
Does your
backpack affect your nerves? Could do it. Tight, narrow straps that sag in the
shoulders can squeeze nerves and interfere with circulation, and you may feel
tingling, numbness, and weakness in your arms and hands.
If you
have difficulty putting on or taking off your backpack, if you have to lean
forward to carry it, or if you have back pain, you may need to correct the way
you carry the backpack (either your total weight or the method you use To load
it). Talk to your doctor if you continue with back pain, or numbness or
weakness in the arms or legs.
Very bulky
or heavy backpacks not only cause back injuries. People who carry very large
backpacks generally do not realize how much space they occupy and can hit
others with their backpacks when turning or moving in crowded spaces such as
school bus aisles. Students also get hurt when they hit large backpacks or when
they fall on top of them.
In
addition, the use of heavy backpacks changes the way you walk and increases the
risk of falls, especially on stairs or other places where the backpack causes
you to lose your balance.
