In today's workplace, the majority of people sit for eight or more hours per day. Think your desk job isn't affecting your health? Think again. A sedentary lifestyle, at home or work negatively impacts your health in multiple ways. Smoking, alcohol, lack of exercise and junk food are all detrimental to our health... we need to add sitting to that list as well. "Sitting diseases" are quickly lowering our lifespans and increasing our healthcare costs.
Sitting requires little to no energy expenditure, "calorie burning drops to one per minute," greatly reduces activation of low back muscles, "electrical activity in the legs shut off, enzymes that help break down fat drop by 90 percent." After two hours, good cholesterol levels drop by 20 percent and after 24, insulin effectiveness drops by 24 percent; your risk of developing diabetes rises. "People with sitting jobs have twice the rate of cardiovascular disease as people with standing jobs. Sitting six-plus hours per day makes you up to 40 percent likelier to die within 15 years than someone who sits fewer than three, even if you exercise" (MedicalCoding&Billing.org). Some of us even spend more time sitting than sleeping.
Sitting affects our internal body systems negatively and our spinal musculature and strength. Remaining seated for prolonged periods of time causes our low back muscles to "take a back seat." If the muscles aren't working properly, other structures, ligaments and intervertebral discs must work overtime (Morl, 2012). Our trunk muscles become deconditioned and lazy. The increase in our sitting times and low back pain are related. The hip flexor muscle (iliopsoas) becomes short and tight with sitting and plays a major role in lower back pain. Lower back pain patients have "atrophy of lumbar muscles," especially the longissimus and multifidi; inactivity and inactivation of such muscles is to blame, sitting being the main culprit (Morl, 2012). The study also found that "lumbar muscle activation does not differ when seated on an exercise ball, different dynamic office chairs or on a reference chair." Full story...
