We all know that sitting too much is bad and most of us intuitively feel a little guilty after a long TV binge. But what exactly goes wrong in our bodies when we park ourselves for nearly 8 hours per day – the average for an American Adult ?!? There is a chain of problems from head to toe. We will be addressing each of these very important issues.
LET'S BEGIN WITH ORGAN DAMAGE
Muscles burn less fat and blood flows more sluggishly during a long sit, allowing fatty acids to more easily clog the heart. Prolonged sitting has been linked to high blood pressure and elevated cholesterol, and people with the most sedentary time are most than twice as likely to have cardiovascular disease than those with the least.
Studies have linked sitting to a greater risk for colon, breast, and endometrial cancers. The reason is unclear, but one theory is that excess insulin encourages cell growth. Another is that regular movement boosts natural antioxidants that kill cell-damaging – and potentially cancer-causing – free radicals.
The pancreas produces insulin, a hormone that carries glucose to cells for energy. However, cells in idle muscles don’t respond as readily to insulin, so the pancreas produces more and more. This can lead to diabetes and other diseases. A 2001 study found a decline in insulin response after just one day of prolonged sitting.
Sitting Is The New Smoking
From the driver's seat, to the office chair, and to the couch at home, Americans are now spending more time than ever in a seated position. Sitting has been labeled as being even more dangerous than smoking, killing more people than HIV and is more dangerous than parachuting. We are truly sitting ourselves to death.
