Abstract: High-altitude climbing presents serious physiological challenges for climbers originating from low-altitude or near-sea-level environments. The progressive reduction in atmospheric pressure and oxygen availability at elevation can induce hypobaric hypoxia, acute mountain sickness, and potentially life-threatening conditions such as high-altitude cerebral edema and high-altitude pulmonary edema. Traditional acclimatization protocols require climbers to spend several days or weeks ascending gradually on the mountain; however, prolonged on-site exposure increases the risk of illness, imposes significant logistical burdens, and extends total expedition duration. This review proposes a systematic, multi-phase strategy designed to accelerate high-altitude adaptation, prevent altitude-related illnesses, and reduce overall climbing time. The proposed framework integrates historical perspectives on acclimatization physiology, key physiological indicators, simulated altitude training methodologies, on-mountain safety protocols, individualized risk assessment, and sleep recovery management. Critical trainable parameters include oxygen saturation maintenance, resting heart rate, hypoxic ventilatory response, aerobic endurance, maximal oxygen uptake, and standardized symptom scores. During the pre-departure phase, climbers may employ hypoxic tents, low-oxygen exercise sessions, structured aerobic conditioning, lower-limb strengthening programs, and systematic self-monitoring to enhance physiological readiness. During the ascent phase, the strategy incorporates supplemental oxygen administration, medically guided pharmacological interventions, climb-high-sleep-low practices, controlled ascent rates, rigorous hydration management, continuous symptom monitoring, and timely descent protocols when necessary. This review concludes that by shifting a substantial portion of the acclimatization process into a controlled pre-climb preparation stage, climbers can significantly reduce their risk of altitude sickness and shorten total expedition time.
