Fight Wrinkles With Exercise

Research has shown that exercise can delay (and even reverse!) the signs of aging. A study conducted by McMaster University revealed that sedentary lifestyles contribute to balding, grey hair, saggy skin, and wrinkles.

Researchers used mice for the first portion of their experiment. The rodents were split into two groups: one group had an exercise wheel and the other did not. Results revealed that the sedentary mice quickly became frail and ill. Their fur also began to grey and fall out.

Meanwhile, the mice that exercised never got grey fur at all. Although their fur did fall out, it was in much smaller percentages than in the sedentary group. But most importantly, the active mice maintained healthy organs.

After examining the results of the study, the researchers decided to see if the same results would occur with people. Again, two groups: one group exercised for three sessions a week, the other didn’t exercise at all. Participants ranged in age from 20 to 84.

Researchers found that those who exercised had dramatically better skin. But researchers also acknowledge the fact that some of the differences could be attributed to diet, genes, environmental factors, and other lifestyle choices.

The only true way to examine the effect then, would be to take the sedentary group and have them start exercising. So that's what researchers did. After just three months, researchers found improvement in the tone, appearance, and texture of their skin.

Scientists still haven't pinpointed an exact reason as to why exercise makes for young-looking skin. Some researchers theorize it’s because of the increased blood circulation. Others believe it’s because exercise relieves stress, which can be a major contributor to skin problems. And yet others think it’s because exercise helps the body get rid of toxins. Either way, there’s substantial evidence that points to the fact that exercise gives people a more youthful, radiant glow.
