At what altitude does it become difficult to breathe?
When you’re mountain climbing, hiking, driving, or doing any other activity at a high altitude, your body may not get enough oxygen. The lack of oxygen can cause altitude sickness. Altitude sickness generally occurs at altitudes of
8,000 feet and above
. People who aren’t accustomed to these heights are most vulnerable.
Can Mount Everest be climbed without oxygen?

headaches and dizziness apart from breathlessness
. You must consult with your doctor if you observe any of these symptoms so that you can be put on supplemental oxygen to raise the oxygen saturation of the blood.
Do you need oxygen at 20000 feet?
