At what elevation is it harder 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.

Is air thinner at higher altitudes?

As we move up higher in the column of air, there are fewer and fewer molecules occupying this space. It's this reason that the air becomes less dense the higher up in altitude you go, while the air is denser down towards ground level.

Can you breathe at 18000 feet?

At 10,000 feet above sea level, the normal saturation for a human breathing regular air is 87 percent. Go to 18,000 feet without supplemental oxygen and the saturation drops to 80 percent (thanks to the partial pressure of oxygen being just 21 percent of the atmospheric pressure at any altitude).

Is high elevation good for your lungs?

High altitudes can cause a range of health issues, including high-altitude pulmonary edema (HAPE).

Can you breathe at 40000 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 get altitude sickness at 5000 feet?

When changes in altitude overpower our ability to acclimatize, we can end up with high altitude illness. This can occur at elevations as low as 4-5,000 feet (the city of Denver, Colorado).
