Since the air pressure is lower at high altitudes, your body may struggle to absorb much-needed oxygen. This can cause disorientation, headaches, nausea, shortness of breath and weakness. In severe cases people have been hospitalized. There are many ways to get used to the altitude so you can still enjoy your getaway.
The effects of high altitude on humans are considerable. The percentage saturation of haemoglobin with oxygen determines the content of oxygen in our blood. After the human body reaches around 2,100 m (7,000 feet) above sea level, the saturation of oxyhemoglobin begins to plummet.ountain medicine recognizes three altitude regions that reflect the lowered amount of oxygen in the atmosphere: 1  High altitude = 1,500â3,500 metres (4,900â11,500 ft). 2  Very high altitude = 3,500â5,500 metres (11,500â18,000 ft). 3  Extreme altitude = above 5,500 metres (18,000 ft).
