Large-scale study reveals deviations in sleep duration accelerate biological aging across multiple organs, suggesting healthy sleep promotes longevity.
In a recent large-scale study of biological ageing clocks published in Nature , the MULTI Consortium now shows sleep, often treated as a lifestyle habit, is a measurable sign of temporal biology. Their work suggests that deviations from optimal sleep duration are associated with accelerated biological aging across multiple organs and that healthy sleep may be one of the most practical and scalable ways for promoting longevity and reducing chronic disease risk. 1
