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.
