I chose to research about posture because sometimes, I find myself sitting in a way that my back looks like a ‘C’. This lead me to think about what the effects of poor posture are. We all sit down everyday-on the way to school, during lessons, to eat, to work and several other times. We all sit to relax, enjoy or work, therefore poor posture is a health issue to not just teenagers, but anyone who doesn’t maintain a good posture. I had already known that bad posture can lead to several bones to shift in your back, which can sometimes be visible, but I didn’t know how harmful it can be and its internal effects.
What seems like such a harmless and relaxing habit actually has the power to change your health. Sitting itself has its own risks but poor posture magnifies those risks and creates a greater health risks. It effects the body physically (body functions stopped working, bones shift, more likelihood of accidents, can lead to diseases), mentally (your brain cannot think as well) and emotionally (you feel more sensitive and greater pain).
The short term effects of poor posture are that when your back is slouched, your lungs bend due to the shape of the back. This limits the amount of oxygen entering your body. Your blood flow also decreases due to bent joints and muscles and is not able to flow as easily. Your brain requires both of these to be able to function effectively, but due to the limited amount supplied to the brain, it is unable to think as quickly or smartly. Temporary pause of lipoprotein lipase in your blood is also a short term effect of poor posture. Lipoprotein lipase is an enzyme your blood releases to break down the fat in your blood. While you are seated, your body is not able to burn fat as well. Headaches also occur due to tension and stress.
The long term effects are very harmful, and in some rare cases it can cause death. Swelling of muscles and small rips are caused by certain muscles being strained, stressed, or stretched for too long. These rips are not because your muscles are strained for too long, but because they are being overused. Reduced blood flow and uneven pressure in different parts of your body can lead to heart diseases, and lack of lipoprotein lipase in your blood can lead to diabetes (because of too much fat in body). It can lead to scoliosis (where your vertebrae align to look like a ‘s’ or a ‘c’) because of bone shifts. Digestion, kidney and liver problems can also occur due to slouched positions and the efficiency of organs and body parts.
The picture below states that ‘Sitting is the new smoking’. This is because sitting for excessive amounts of time can lead to similar effects of smoking. It shows a chair looking like a deadly thing because it has the power to change your health.
The solution of this is simple, try to aim for an active lifestyle, but when you have to be in your seat, sit with good posture. Your back should be straight, the screen level at or slightly below eye level, and your elbows and wrists supported.
