Lachlan Fleetwood talks about debates about altitude sickness in the Himalaya and the ways these debates became tied up with ideas about the physiology of Europeans and Himalayans in the 1800s. Fleetwood is the author of “Bodies in High Places: Exploration, Altitude Sickness, and the Problem of Bodily Comparison in the Himalaya, 1800-50,” published in the journal Itinerario 43, no. 3 (2019): 489-515.
