Heavy bags and backpacks can contribute to serious spine problems and even trigger curvature over time. This caution comes from a trauma and orthopedic specialist describing the risks associated with carrying heavy loads in everyday bags.
The most common risk factors relate to how weight is distributed on the shoulders and back.
When a bag is too heavy or carried on only one shoulder, the load is not balanced across the musculoskeletal system. The main weight presses on one side of the spine, prompting a slight bend to redistribute the load. This subtle shift can alter walking style, guiding movement toward the heavier side. Over time, this can deform joints and become a significant factor in spinal curvature, explains the medical professional.
Incorrect posture while standing or walking is another critical factor.
During lifting, people may lean forward to manage the extra weight, and this can pull the shoulders forward in an effort to keep the weight from drifting backward. When the backpack weighs more than five kilograms, there is a real risk of low back and chest discomfort, and even damage to the intervertebral discs. If the weight reaches twenty percent of body weight, the danger of a serious back injury rises sharply, according to the specialist.
Carrying a bag with one hand or over one shoulder also imposes an uneven load on the back and shoulder muscles. Prolonged asymmetry can cause muscle tension and weakness in certain muscle groups due to poor load distribution.
To reduce the likelihood of musculoskeletal issues, the orthopedist advises against routinely carrying heavy items. Carry only what is necessary to limit the risk of spine and joint problems.
Back pain can be mitigated with periodic massage sessions. This therapy helps relax tense muscles, improve blood flow, ease discomfort, and support overall function of the musculoskeletal system. If carrying heavy items is unavoidable, it is beneficial to switch the bag from one shoulder to the other to maintain balance and minimize strain.
A former orthopedic specialist also offers guidance on helping schoolchildren maintain proper posture in daily activities and during transportation of supplies.
