Disruption of our natural circadian rhythm, called chronodisruption, "has a direct role in inducing accelerated aging," notes a recent paper by researchers at the University of Murcia in Murcia, Spain. Reduced Life Expectancy
Disruptions in circadian rhythms lead to reduced life expectancy
“For example, a 6-hour shift of the light–dark cycle every week induced a significant reduction in the lifespan of aged mice,” the paper notes.
“... Similarly, chronic reversal of the light–dark cycle decreases the median lifespan in cardiomyophatic hamsters.
“Therefore, it is generally believed that disruptions in circadian rhythms lead to reduced life expectancy, whereas their appropriate resetting leads to well-being and increased longevity,” they concluded.
