At which altitude does the air begin to be noticeably thinner?
At 12,500 feet the air becomes thinner and oxygen becomes lower making it difficult to breathe.

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
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
High altitudes may mean ambient pressure can drop below vapour pressure hence, you might feel lethargy, sometimes unconciousness and if you are unable to cope up then connect with a doctor to know the best treatment.
