By using wearable devices to monitor and record the physiological data changes and health outcomes (incidence and severity of high-altitude illnesses) of high-altitude migrants at different stages (pre-entry, acute/chronic high-altitude phases, and de-acclimatization phase), and referencing previous cohort studies on high-altitude populations, the study aims to provide a basis for developing personalized health assessment protocols for high-altitude migrants. The formulated assessment protocols and standards will then be validated.
