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.
Air gets 'thinner' with increasing altitude. That's why mountain climbers sometimes need bottled oxygen to breathe, and why it is so easy to get 'winded' while hiking in high mountains or even visiting someplace at elevation. Atmospheric pressure is around 1,014 millibars (14.7 pounds/inch 2) at sea level.t an elevation of 10 km (6 miles or about 30,000 feet), roughly the height of Mt. Everest, pressure drops to 265 millibars. That's less than 30% of the pressure at sea level! Both atmospheric pressure and the density of air decrease with altitude.
