At high altitudes, the air pressure is lower, which means there is less oxygen available for breathing. This condition, known as hypoxia, can lead to several health issues. The body must adapt to lower oxygen levels, which can cause immediate and long-term physiological changes. Common health problems associated with high altitudes include acute mountain sickness (AMS), chronic mountain sickness (CMS), and high-altitude pulmonary edema (HAPE). Additionally, there is evidence suggesting that altitude may influence the incidence of certain chronic diseases and conditions, such as cardiovascular diseases and respiratory disorders.
