Altitude exposure reduces the amount of oxygen available to the body, so a common problem is altitude sickness, with symptoms like headaches, nausea, fatigue, and sleep disturbance as the body tries to acclimate to hypoxia. The typical mitigation is to acclimatize and use a live-high, train-low approach: live at high altitude to trigger adaptations such as increased red blood cell production, but train at lower altitude to maintain training intensity and volume. This setup lets the athlete gain the oxygen-transport benefits of living high while preserving the quality of workouts by training where oxygen is more available. Other options don’t fit because they either misstate the problem (expecting a straightforward aerobic capacity increase) or ignore acclimatization, and they don’t reflect the practical strategy used to balance adaptation with training quality.
