Another study involving children shows that heavy backpacks could be causing them a number of health problems.
Doctors have said kids should not carry more than 10% of their body weight.
One parent said his kids’ bags tend to weigh anywhere from 4,5kg to 13,6kg. That’s closer to 50% of a child’s weight.
“It puts a tremendous amount of stress, postural stress, gravitational stress on the neck, upper back, shoulders, muscles, joints, so it’s a pretty common problem,” says Dr. Dan Davidson, a practicing chiropractor.
Davidson also says that in the long term, the strain can cause posture problems for kids. Constantly staring down at electronic devices is causing a trend of back problems.
