Himalaya Sherpa is a group of descendants of Tibetans living in the highlands of the Himalayas. They show excellent strength, endurance and climbing skills at high altitudes. At these higher altitudes and lower pressures the availability of oxygen is very low. In the highlands, healthy people may experience hypoxia or low levels of tissue oxygen levels. Hypoxia can cause heart failure, pulmonary disease, anemia, and many cancers. Recently, a group of scientists have studied the basis of this metabolic adaptation. There is a genetic difference between the Himalaya Sherpa and the lowland population, which leads to the adaptation of these metabolites. Adaptability ensures the efficient use of tissue oxygen to protect muscle energy at high altitude.

It has long been known that altitude affects humans. The altitude is classified as 1,500 to 3,500 meters above sea level, very high altitude is classified as 3,500 to 5,500 meters, and the extreme height exceeds 5,500 meters (Wilkerson 1). At sea level, the oxygen in the air is about 21% and the pressure is 760 mmHg, but when the altitude becomes 5000 feet, the pressure becomes 483 mm Hg, and the oxygen molecule per breath decreases by 40% (Curtis 2). In this case the oxygen density decreases and the carbon dioxide level increases, which in combination forcibly increases the heart rate and exhalation rate in order to remove an increased amount of carbon dioxide inhalation. When the body's carbon dioxide level is high, it produces more sodium bicarbonate in the bladder, and the body has to increase bladder activity to exclude these compounds. Company!
