Study highlights the epigenetics of life at high altitudes
Humans inhabit an incredible range of environments across the globe, from arid deserts to frozen tundra, tropical rainforests, and some of the highest peaks on Earth. Indigenous populations that have lived in these extreme environments for thousands of years have adapted to confront the unique challenges that they present.
Approximately 2% of people worldwide live permanently at high altitudes of over 2,500 meters (1.5 miles), where oxygen is sparse, UV radiation is high, and temperatures are low. Native Andeans, Tibetans, Mongolians, and Ethiopians exhibit adaptations that improve their ability to survive such conditions. Andeans, for example, display increased chest circumference, elevated oxygen saturation, and a low hypoxic ventilatory response, enabling them to thrive at exceptionally high elevations.

Sagasti announced Monday that 487 people took advantage of their position to receive the Chinese-made Sinopharm vaccine early, during a televised address Monday night, reported state media Andina. We reiterate our indignation and disappointment after being informed that 487 people, including many senior officials, took advantage of their position to be immunized with the Sinopharm vaccines, which came as a complement to those used in clinical trials in our country, Sagasti sai
