Tiny Matters

In 2019, Nathan Hudson-Peacock was serving as an expedition doctor to a group hiking in the Indian Himalayas. At around 17,000 feet, a climber suddenly went from having a mild headache to a life‑threatening cerebral edema. On top of that, a storm was closing in. So, what did he do? How do expedition doctors keep people alive in the harshest places on Earth? Tune in to this week’s episode to find out. In it, we chat with Nathan as well as high altitude physician Monica Piris, who has spent much of her time on Everest. We dig into the world of expedition medicine: the preparation, the danger, the breathtaking environments, and the moments that can reshape your understanding of the planet and the impact of climate change.
