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. Blood sugar levels drop. And after meals, blood sugar levels spike due to inactive skeletal muscles, which are responsible for 80 percent of glucose disposal when active. The level of triglycerides in the blood jump during inactivity, because muscles stop producing an enzyme that usually captures this type of fat from the blood in order to turn it into fuel. Even HDL cholesterol levels (the good cholesterol) drop 20 percent after as little as one hour of uninterrupted sitting. Inactivity also appears to switch on or off dozens of genes that trigger additional risk factors.?
