According to a new Australian study of almost a quarter million healthy adults, sitting too much increases the risk of premature death (Archives of Internal Medicine). The greatest risk was for those who sat for at least eleven hours daily--they were 40% more likely to die within 3 years than those who sat less than four hours daily. Prolonged sitting can have adverse effects on health including an increased risk of hypertension, heart attack, abdominal obesity (i.e., a waist size over 40 inches in males and over 35 inches in females may shorten life expectancy by three to five years), chronic kidney disease, some cancers (i.e., colon, breast), decreased HDL (the good cholesterol), increased triglycerides, and elevated blood sugar (which may increase the risk of type-2 diabetes). Type-2 diabetes, heart disease and cancer are inflammatory diseases. Regular exercise can attenuate inflammation and therefore reduce the risk of incurring these lifestyle-related diseases. Exercise may increase your maximal oxygen consumption, decrease your bodyfat, reduce your blood pressure, increase your HDL level, reduce heart attack risk, and increase insulin sensitivity (lessening type-2 diabetes risk).
BOTTOM LINE: Take a short break (just a few minutes) every hour while sitting to get up, stretch, and take a short walk to get the blood circulating. If you sit a lot (i.e., at least 8 hours daily), performing at least 60 minutes of moderate exercise (e.g., brisk walking) every day may lessen mortality rate associated with being sedentary. By doing this, you can literally increase your life expectancy.
