It would be somewhat daunting to create a comprehensive list of all of the proven benefits that regular exercise provides to the human body but here's another recent benefit discovered by scientist working in Texas..
A new study published last month in Nature and conducted at the University of Texas Southwestern Medical Center in Dallas has found that regular exercise speeds up the removal of garbage from your body.
For a long time scientists have known that the everyday wear and tear of just living is enough stress on the body to create worn-out, and broken-down cellular components.
According to the New York Times:
"In most instances, cells diligently sweep away this debris. They even recycle it for fuel. Through a process with the expressive name of autophagy, or “self-eating,” cells create specialized membranes that engulf junk in the cell’s cytoplasm and carry it to a part of the cell known as the lysosome, where the trash is broken apart and then burned by the cell for energy.
Without this efficient system, cells could become choked with trash and malfunction or die. In recent years, some scientists have begun to suspect that faulty autophagy mechanisms contribute to the development of a range of diseases, including diabetes, muscular dystrophy, Alzheimer’s and cancer. The slowing of autophagy as we reach middle age is also believed to play a role in aging."
The study compared two sets of mice.
One set was sedentary while other set ran. The New York Times goes on to repor that the study concluded that, "after just 30 minutes of running, the mice had significantly more membranes in cells throughout their bodies, the researchers found, meaning they were undergoing accelerated autophagy."
Autophagy is, "a major mechanism by which a starving cell reallocates nutrients from unnecessary processes to more-essential processes, according to Wikipedia."
