Molecular Mechanisms of High-Altitude Acclimatization
International Journal of Molecular Sciences, 2023 High-altitude illnesses (HAIs) result from acute exposure to high altitude/hypoxia. Numerous molecular mechanisms affect appropriate acclimatization to hypobaric and/or normobaric hypoxia and curtail the development of HAIs.

Altitude sickness and altitude adaptation [PDF]
Acta Physiologica, 2017 For as long as humanity can recall, it has probably been a dream of mankind to conquer mountainous heights and the mysterious deep. Loss of innocence is a common theme across ancient religions. Ancient Hindu legend has an interesting variation on the story: When Brahma realized that man did not deserve divinity, he decided to take it from them and hide

Global and country-level estimates of human population at high altitude
Proceedings of the National Academy of Sciences of the United States of America, 2021 Estimates of the global population of humans living at high altitude vary widely, and such data at the country level are unavailable. Herein, we use a geographic information system (GIS)-based approach to quantify human population at 500-m elevation ...

Impact of High Altitude on Cardiovascular Health: Current Perspectives
Vascular Health and Risk Management, 2021 Globally, about 400 million people reside at terrestrial altitudes above 1500 m, and more than 100 million lowlanders visit mountainous areas above 2500 m annually. The interactions between the low barometric pressure and partial pressure of O2, climate,
