Don't let your bag drag you down! Think for a minute about the computer that you are carrying around, the BIG purse that has the kitchen sink in it, or the books and school supplies that your kids are carrying in a backpack, slung across one shoulder. You may think that it's harmless, think again! Strain to the body from carrying bags that are way too heavy may end up leading to complications that may include muscle spasms, pain in the back, neck or joints, sprains and strains and even headaches. Many studies have shown that it is healthier to carry lighter loads as well as using both straps of the backpack instead of messenger bags or large purses. The muscles in the neck and shoulders run up into the head, while the nerves in the neck run all the way down into the arms. This means that a muscle strain in one section of the body can have effects throughout the rest of the body. When stress is placed on the spine beyond what it can absorb, spinal imbalance - and injury - is the result. A heavy backpack, for example, can pull a person backward, which causes that person to compensate by either bending forward or arching the back, putting the spine in a compromised position. Throwing a backpack over one shoulder can also cause a person to lean to one side to offset the weight. This can lead to poor posture, muscle strains and neck and back pain. Backpacks with narrow straps can also interfere with circulation and nerve function in the arms causing tingling, numbness and weakness in the arms and hands. Heavy loads carried as a child can lead to low back pain that lasts through adulthood. Clinical professor of occupational therapy at Boston University, Karen Jacobs says that a child wearing a backpack incorrectly can be one of the main contributing factors for discomfort, fatigue, muscle soreness, and back pain in children. Dr. Douglas Armstrong, an orthopedic specialist at Penn State Hershey Medical Center explains that children are at a higher risk for spine problems based on how they carry the backpack, pick it up, and put it on, not from the weight. We all can avoid back pain by doing these 3 things: 1. Distribute the load evenly 2. Keep the backpack close to the body and bend at the knees when picking it up. 3. Use both straps while wearing the backpack, and keep it centered on the body. Dr. Armstrong says, "Two straps are always better than one, because you can keep the backpack near your center of gravity. However, it is OK to carry light items in a satchel or bag with one strap over the shoulder." Farther studies have revealed that lack of balance and stability account for 95% of foot and back pain issues. So, think smart and take care of your back by making your bag lighter and carrying it correctly. If you are suffering from foot or back pain and looking for a drug free solution.
