Time-Dependent Sleep Disruption at Simulated 7,000 m in Rats: Delineating the Compensation-to-Decompensation Transition.
High-altitude exposure disrupts sleep, but the temporal dynamics remain poorly defined. This study characterises time‑dependent changes in sleep architecture, HPA axis function, inflammation, and central sleep‑regulatory molecules during subacute hypobaric hypoxia. Male Sprague‑Dawley rats were exposed to simulated 700...
