First of all, the growing child's spine is not fully developed. Carrying a schoolbag like a hill for a long time will deform the child's spine. If the compression cycle is long, the growth and development of spine bones will slow down, which will cause indelible damage to the child's future physical development and affect the child's height development.
Secondly, children who carry overweight schoolbags for a long time will subconsciously lean forward to keep their balance. After a long time, they will also maintain this posture in peacetime, leading to early hunchback and affecting the child's posture. In addition, it may also cause the child's shoulders to be unbalanced, resulting in one shoulder being high and the other shoulder being low, that is? High and low shoulders? , looks no spirit.
In addition, the shoulder strap of the schoolbag exerts too much pressure on the shoulder, which will strain the shoulder muscles under long-term pressure, and will also cause great damage to the neck, waist muscles and other parts, affecting the healthy life in the future.
Some scientists have found and pointed out through research that the schoolbags used by adolescent children for a long time should not be larger than 10% of their own weight. The weight of schoolbags exceeding this range is overweight, which is harmful to the growth and development of children. So, for primary and secondary school students now? Reduce the burden? The problem is also a hot topic.
The Ministry of Education and school parents should pay attention to this problem, formulate relevant policies or find out corresponding countermeasures, so that children can learn and grow healthily in the sun. Such as: reasonable and appropriate purchase of teaching materials; Schools teach children how to organize their schoolbags scientifically; Parents buy tie-rod schoolbags to reduce the weight of shoulders.
