How to make a light student bag?

It has always been a topic of public concern to give students backpacks. Do you know how to weigh the students? According to an article in the American journal of life, it is best not to exceed 10 percent of the weight of the backpackers.

Research by the American physical therapy association on 9 graders has shown that heavy backpacks and backpacking errors can lead to back injuries and muscle fatigue.

Study researcher Mary Ann wilmath said the child's heavy backpack would cause the spine to be convex, lateral, forward or distorted.

At the same time, muscles may fatigue due to extreme stress, and the neck, shoulders and back are vulnerable. If the weight of the bag exceeds 10 percent to 15 percent of the weight of the backpackers, the damage to the body will multiply. As a result, she recommends keeping the backpack weight below 10 percent of the backpackers' weight.

The American physical therapy association recommends that children use double-shouldered backpacks. Experts say a double shoulder pattern can be used to reduce the weight of a backpack and thus reduce the likelihood of distortion.

It's also a good choice for younger students, because seniors in the U.S. often need to move up and down the stairs to change their classrooms, while lower-grade students don't have the trouble.

In addition, it is also important to properly place the items in the bag. The heaviest items are placed close to the back.
