Can you breathe 30000 feet?
Somewhere between 30,000 and 40,000 feet the pressure around you becomes far too low to push those oxygen molecules across the membranes in your lungs, and you get hypoxic (altitude sickness). If you try to breathe 100 percent oxygen above 40,000 feet for very long without a special type of mask, you’ll die.
Can you breathe 15000 feet?
Above 10,000 feet cabin altitude — most of us will go unconscious above 15,000 to 20,000 feet. Above 10,000 feet, with the yellow emergency oxygen mask the airlines provide (or any supplemental oxygen supply not provided under pressure) — no problem.
Can you breathe at 14000 feet?
At 14,000 ft, the air has 43\% less oxygen than at sea level. Because of the reduced air pressure at high altitude, the volume of air you breathe into you lungs contains less oxygen molecules in each breath.
Can you breathe at 35000 feet?
Whether you are flying aboard a small Cessna or a jumbo-sized Airbus A380, you can breathe freely inside the cabin without wearing a mask or respirator. Even at a cruising altitude of 35,000 feet, you shouldn’t have trouble breathing.
Is high altitude good for you?
Living at higher altitudes seems to be associated with lower mortality from cardiovascular diseases, stroke and certain types of cancer. In contrast mortality from COPD and probably also from lower respiratory tract infections seems to be increased.
Is living at high altitude good for you?
Living at high altitude reduces risk of dying from heart disease: Low oxygen may spur genes to create blood vessels. Summary: Researchers have found that people living at higher altitudes have a lower chance of dying from heart disease and live longer.
What is the oxygen level at 8000 feet?

What is the oxygen level at 10000 feet?
Oxygen Levels By Altitude
| Altitude (ft) | Altitude (m) | Effective O2 \% |

What altitude can you survive at?
Humans have survived for two years at 5,950 m (19,520 ft, 475 millibars of atmospheric pressure), which is the highest recorded permanently tolerable altitude; the highest permanent settlement known, La Rinconada, is at 5,100 m (16,700 ft).
What is the healthiest altitude to live at?
After tracking nearly 7,000 healthy adults for 10 years, researchers from the Centre for Nutrition Research at the University of Navarra discovered that those who lived at 1,500 feet or above had a 25 percent lower risk of metabolic syndrome than those residing below.
