At high altitude, low oxygen partial pressure predisposes human body to hypobaric hypoxia that may lead to high-altitude illness. Currently, singing had been used for rehabilitation of patients with lung diseases but its role in high-altitude low oxygen environment is still scarce. This study aims to examine the effect of singing in improving oxygen saturation at different levels of high altitudes in a hypobaric chamber. Eight healthy volunteers were assigned to three interventions at three simulated altitudes (sea level, 3000 m an
