Why does level of oxygen decrease when altitude increases?

High altitudes can cause low oxygen saturation levels or desaturation of an individual's blood. It happens because of low atmospheric pressure at high altitudes. Oxygen saturation levels refer to the extent hemoglobin is bound or saturated to oxygen.

Why is it difficult to breathe in high altitudes?

At higher altitudes such as on top of a mountain, the air is less dense and this means that the partial pressure of oxygen is lower. Hence, the fall in atmospheric pressure at higher altitude decreases the partial pressure of inspired oxygen

Is there such a thing as 'reverse altitude sickness'?

Humans can certainly experience reverse altitude sickness, known as high-altitude de acclimatisation syndrome (HADAS). When people who live at low altitude have adjusted to a high-altitude, low-oxygen environment, they can get any of a large number of possible symptoms of HADAS when returning to a lower altitude.
