Dyssomnia insomnia are important risk factors for insulin resistance, obesity, MetS, type 2 diabetes mellitus with a degree influence similar to traditional factors. Thus, treatment dyssomnia is one key tasks prevention MetS.

Dysregulated rhythms are characteristic aging crewed spaceflight, associated with, for example, musculoskeletal atrophy. Molecular insights into spaceflight-related alterations regulation muscle still missing. Here, we investigated potential functional consequences disruptions on using published omics datasets obtained from spaceflights other clock-altering, external (fasting exercise), or internal (aging) conditions Earth. Our analysis identified network muscle-associated pathways, as a result spaceflight duration mice, which resembles aging-related gene expression changes observed humans Earth (e.g., ATF4 downregulation, with atrophy). Furthermore, according to our results, factors such exercise fasting lead core-clock network, may compensate disruption during spaceflights.
