Face it. We all felt a sense of detrimental fear when our first gray hair appeared. Didn’t we JUST get out of college? Weren’t you carded last week? Gray hair is nature’s way of letting you know you are aging and hopefully, maturing. But, can we stop it?

From Botox to glycolic peels, we poke, scrape and do whatever it takes to stay young. Looking younger is a multi-billion dollar business. Dr. Mark Tarnopolsky, a professor at McMaster University in Ontario, recently discovered that exercise greatly reduced and even erased signs of aging in mice. His findings were published last week in The Proceedings of the National Academy of Sciences.

The study centered on mitochondria, a microscopic unit of a cell. They are responsible for creating fuel for cells to do their jobs. Mitochondria grow and multiply on their own and have their own separate DNA – distinct from cells where they live. Mitochondria can often mutate and cells repair those mutations. As we get older, more mutations occur and fewer repairs happen. Scientists believe the lack of healthy mitochondria is the main cause of aging. This is when hair starts to turn gray or fall out; skin loses elasticity and so on. But, enough of that science lesson!

Within the year of their study, the mice that ran 45 minutes every day had NO signs of aging – no gray hair, no muscle loss. Not one mouse in the exercise group died of natural causes. They also found that the jogging mice produced a protein (PGC-1alpha) that regulates genes involved in metabolism and creating/repairing mitochondria.

All the non-exercising mice aged and died.

Dr. Tarnopolsky and his colleagues expected a difference, but not one so distinct. He concluded, “Exercise alters the course of aging.” He also went on to say that in terms of exercise, “anything is better than nothing.” There will be further studies to help correlate how this relates to humans and anti-aging.

That’s promising news for us and the Real Housewives! Now go jump on that treadmill!
