The average adult spends about eight hours a day sitting down. Is it a chair or armchair, the dangers are the same. Although sitting may feel harmless when you are seated for a long time every day could lead to degeneration of muscles and significantly reduce your mobility.
Slouching or Hunchback Posture
Sitting is an inevitable part of everyday life and often is accompanied by poor posture. If your back is straight, it forces your body to rely on abdominal muscles to maintain posture. But if you lower your shoulders (as almost all do), abdominal muscles are not working. As a result, the load is shifted to the lower back and pelvis. No matter how comfortable you sit hunched, this position will twist your spine like a rainbow, and in time will lead to muscle atrophy.
Muscle atrophy is a degeneration of muscle fibres occurring due to lack of exercise. This is one of the reasons why active lifestyle is recommended to the sedentary people. And because sitting is, in fact, a period of inactivity, it may lead to exactly this- muscle fibres shrink and thus weaken the body. This is especially true for the hip flexors that shorten and limit the optimal range of motion.
Lack of mobility
Prolonged sitting leads to tension in all parts of the body including the thighs, buttocks, back and legs. Thus increase a danger that even ordinary movements like walking become increasingly difficult over time. As a result of sitting too long, the discs at back of your spine get pressed unevenly, causing tendons to harden. These tendons are responsible for the uneven weight distribution in your body including the spine, which leads to reduced mobility and damage to the discs.
Impaired blood circulation
Among other things, bad posture while sitting leads to problems with blood circulation in the legs. When sitting the blood flow in your veins and arteries is restricted; the condition is called varicose (dilated) veins. More common in women, but men are not insured. But there is a more serious injury that may occur as a result of impaired circulation – deep vein thrombosis; where the health consequences are extremely serious.
How to stand properly
Stay with completely straight spine without leaning forward. Relax your shoulders and keep your feet flat on the floor. Keep your hands close to your body and bend them at the elbows at a 90-degree angle. Whenever possible, get up and walk around. At first, all this probably will be a little (or very) uncomfortable. But over time, this seemingly small change – correct the stand will change your quality of life for the better.
