How does one avoid altitude sickness?
Avoid visiting places on the same day when you get to higher altitudes. Acclimatise and only then get to places which requires climbing.

At altitude, the reduced oxygen content of the blood induces breathing instability, with periods of deep and rapid breathing alternating with central apnea. This breathing pattern is called high-altitude periodic breathing (PB).
Once you have mastered the belly breath, you can add resistance to your exhalation by pursing your lips and exhaling forcefully, and this is what mountaineers call the Pressure Breath. This is one of the most important breaths for climbing at high altitudes that helps combat the decrease in atmospheric pressure
Yes, oxygen is lower in higher 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
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.
