A groundbreaking study from Harvard Medical School researchers has revealed that breathing air with reduced oxygen levels—similar to conditions at high mountain elevations—can prevent and even reverse Parkinson’s disease symptoms in mice. The findings, published August 6, 2025, in the scientific journal Nature Neuroscience, challenge conventional understanding of Parkinson’s disease and suggest an entirely new approach to treatment that focuses on oxygen levels in the brain rather than targeting protein clumps. “The fact that we actually saw some reversal of neurological damage is really exciting,” said Dr. Vamsi Mootha, professor at Harvard Medical School and co-senior author of the study. … Continue reading Low-Oxygen Air Reverses Parkinson’s Symptoms in Mice, Harvard Study Shows 11% O2 Prevents Neuron Loss
