The carriage of heavy schoolbags by children is a concern for all those involved in student health and well-being. Backpacks are the most commonly used type of bag, and overweight backpacks are associated with several health issues, including increased spinal curvature, discomfort, and back and shoulder pain while the majority of students were carrying as much as 30% to 40% of their body weight. In this way posture modifications have been reported when children carry a load that corresponds to more than 10% of their body . In addition Items carried by students in their daily school bags have been found to include, but are not limited to books, pencil cases, scientific calculators, and sport-specific training clothing, lunch boxes and full water bottles. Even an empty backpack can distort posture and cause pain. There is no way to safely carry weight in a backpack, no matter how light the load, because it disrupts our body mechanics by design .
