In a new study, researchers discovered a link between reduced oxygen intake and longer lifespan in lab mice, highlighting the potential of “oxygen restriction” in anti-aging. Mice bred to age faster, when moved to an oxygen-restricted environment , lived about 50% longer than mice in normal oxygen conditions . This extended lifespan was not due to changes in food intake, suggesting other mechanisms are at play.
To explore the anti-aging potential of oxygen restriction in mammals, Rogers and colleagues conducted lab experiments with mice bred to age more quickly than other mice while showing classic signs of mammalian aging throughout their bodies. The researchers compared the lifespans of mice living at normal atmospheric oxygen levels to the lifespans of mice that, at 4 weeks of age, had been moved to a living environment with a lower proportion of oxygen .
Prior research has shown that dietary restriction extends the lifespan of the same kind of fast-aging mice used in this new study. Therefore, the researchers wondered if oxygen restriction extended their lifespan simply by causing the mice to eat more. However, they found that oxygen restriction did not affect food intake, suggesting other mechanisms were at play.
