Discuss the unhealthy biological processes that result from extended periods of sitting

Answer 1

Our bodies are simply not designed for extended periods of sitting. As we sink into inactivity, our biological processes begin to change, down to a cellular and molecular level. Researchers are only beginning to understand all of the factors at work, but studies show, for example, that blood flow becomes sluggish and is more likely to form life-threatening clots in the lungs and legs. Slower blood flow also means less oxygen and glucose delivered to the brain and body, and as a result cognitive function declines and the feeling of fatigue increases. An act as simple as standing several times throughout the day can keep abdominal, gluteus, and other antigravity muscles working. Additionally, during extended sitting, cells in idle muscles don't respond to insulin (including skeletal muscles, which are responsible for 80 percent of glucose disposal during activity); thus, insulin resistance increases along with the accompanying risk for diabetes and cardiovascular disease.
