Genetic adaptation allows Tibetans to live at high altitudes without altitude sickness
TLDR Tibetans have developed a genetic adaptation that allows them to live at high altitudes without experiencing altitude sickness, by keeping more nitric oxide in their bodies which helps dilate blood vessels and deliver oxygen more efficiently.
Timestamped Summary
00:00
Tibetans have developed a genetic adaptation that allows them to live at high altitudes without experiencing altitude sickness.
02:10
Tibetans are able to live at high altitudes without experiencing altitude sickness, unlike regular sea level dwellers.
04:29
Tibetans are hypoxic, but they do not display any symptoms of altitude sickness, which has raised curiosity among researchers.
06:43
Tibetans have acclimated to hypoxia by keeping more nitric oxide in their bodies, which helps dilate blood vessels and makes it easier to deliver oxygen throughout the body.
09:00
The highlanders in Ethiopia living at a high altitude do not have any known adaptations to avoid hypoxia like the Tibetans and Andean dwellers do.
11:14
People from Tibet and the Ethiopian highlands may have trouble breathing at sea level or below, but it is not known if their bodies adapt quickly or if they experience a rush of oxygen.
