Going into space accelerates aging
Being in outer space may accelerate cardiovascular disease and the aging of blood vessel cells, according to new research published in The FASEB Journal.
Researchers conducted experiments on the International Space Station in order to analyze how blood vessel cells change in space. They compared space-flown cells to cells in normal gravity and found that space-flown cells demonstrated significant oxidative stress, inflammation and biological aging.
The findings mean that people who fly into space need to take precautions to remain in the best health possible, especially the deeper into space they go.
More research into what happens on a cellular and molecular level during the aging process of blood vessel cells may also help researchers find ways to prevent premature aging.
