Heavy Backpacks Make Child Into Bad Healthy

These days is the time for chinese student go back to school to study.And most parents will buy some stationeries or new design backpacks for their children.It also means that most student will require to lug bulky textbooks to and from class every day are adding up to 15 pounds of extra weight onto their backs.

When extra books or clothing, a musical instrument or other equipment are added, the weight they carry can reach 20 pounds.But whatever the figure, those packs are simply too heavy for their still-forming bones and muscles.

According to the American Academy of Pediatrics (AAP), a child’s backpack shouldn’t weigh more than 10 to 20 percent of their weight, but often this limit is exceeded, and it could certainly lead to strain and even injury.
   
Wearing a heavy school bag for prolonged periods may cause excessive strain in one's neck, back and shoulders.Over time, muscles may fatigue, and the wearer may fall into poor posture, which may lead to muscle imbalances, which, if long-term, may cause an increased risk of injury.

The issue has been raised repeatedly in countries all over the world for more than a decade. In December 1999, doctors in Milan reported in The Lancet that 34.8 percent of Italian school children carried more than 30 percent of their body weight at least once a week, exceeding limits proposed for adults.

So how should we do to help children to avoid this damage?

One teacher responded with some helpful suggestions, including having the boys take a few minutes at the end of the school day to determine what they really needed to take home with them.They don't have to bring everything home every night.And a lot of kids don't take much time at their lockers to sort out what they do need.

Another helpful suggestion is selecting a well-designed backpack and adjusting it to sit properly on the child's back. Select a backpack that is no bigger than absolutely necessary — the more room in the pack, the more the child is likely to carry. The pack should have wide, padded, adjustable shoulder straps (narrow ones can cause nerve damage), a padded back, and compartments within so that the heaviest items can rest against the child's back.
