Brief Exercise Slows Aging
by Dr. Kristie
There’s good news if you don’t want to spend an hour jogging on a
treadmill. Even brief exercise helps to prevent stress-related damage
to immune cells that can jeopardize health. According to a
new study, as little as 42 minutes of vigorous exercise over a three
day period helps to keep immune cells that fight disease healthy .
Telomeres and Aging
One marker for cell aging is telomere length. Telomeres are short
regions of DNA that protect the tips of chromosomes, the cell’s
genetic material, from damage. Short telomeres are not only
a marker for aging, but they’re associated with a higher risk of
chronic health problems such as diabetes and heart disease. Scientists
already know that stress can shorten telomere length. Obviously,
having longer telomeres would be of benefit from a health
standpoint.
Cell Aging and Brief Exercise
Researchers at the University of California at San Francisco looked
at immune cell telomere length in 62 post-menopausal women
who were under significant stress. They questioned these women
