The independent predictive effect of insomnia symptoms before high-altitude exposure on acute mountain sickness: an observational study of healthy volunteers at 2726 m

Baseline AIS scores serve as an independent predictor of AMS, supporting the incorporation of sleep assessment into pre-ascent. health screening for high-altitude mountaineering. However, this finding is derived from a small sample within a specific cohort; its predictive utility and generalizability must be independently validated in future studies with larger and more diverse populations.
