Uphill Athlete Podcast Part One: Xenon Gas and High-Altitude Performance in conversation with Dr. Peter Hackett
Apr 25, 2025
Dr. Peter Hackett, a board-certified emergency physician and high-altitude medicine pioneer, dives into the controversial use of xenon gas for enhancing climbers' performance. He discusses its historical significance and potential to stimulate erythropoietin while raising concerns about safety and lack of convincing evidence. The conversation emphasizes the need for controlled research, citing the risks of unsupervised use. Dr. Hackett also underscores the importance of balancing scientific rigor with experiential insight in the climbing community.

Episode notes
Xenon Gas Properties and Effects
- Xenon is a rare noble gas used as a powerful anesthetic in controlled settings.
- It stimulates EPO production temporarily but hasn't proven to increase red blood cells or improve performance at altitude.
EPO and High Altitude Physiology
- EPO stimulates red blood cell production but the process to improve performance takes weeks.
- Hemoglobin level matters less above 4,000 meters; oxygen saturation is more critical for high altitude performance.
Xenon’s Short-term Effect and Safety
- Studies show xenon raises EPO briefly but no evidence supports improved hemoglobin or athletic performance.
- Claims about xenon's benefits are mostly anecdotal; safe application requires medical supervision and precise dosing.
