They seem to be reddish because of greater concentration of hemoglobin the oxygen carrying protein the main component of red blood cells.
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.
They have larger lung capacity than people living in the plains.
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
