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.
They seem to be reddish because of greater concentration of hemoglobin the oxygen carrying protein the main component of red blood cells.
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
At high attitudes, hypoxia-induced erythropoietic drive results in erythrocytosis and an increase in hemoglobin concentration and hematocrit. Hence people with SCD should be careful and report abnormalities to the doctor immediately.
High altitude environments can be debilitating to unacclimatized individuals exposed to elevations above 3,000 m (9,843 ft) for periods ranging from several hours to days. Moderate hypoxia induces substantial alterations in physiological and psychological parameters within a few hours
