Altitude training enhances oxygen efficiency, boosts metabolism, and has various health benefits, including improved wellbeing and skin rejuvenation. Optimal training lasts four to seven days at altitudes between 2200m and 3500m, with the potential to increase red blood cell mass and hemoglobin concentration. However, individual responses vary, and adaptations, including increased caloric and iron intake, are necessary to mitigate risks such as overtraining and altitude sickness.
