Question

. People living in plains when going to mountains take some time to adjust. They might feel some problems to breathe. Why?

Answer 1

Answer:

Explanation:

The human body can adapt to high altitude through immediate and long-term acclimatization. At high altitude there is lower air pressure compared to a lower altitude or sea-level altitude. ... The partial pressure gradients for gas exchange are also decreased, along with the percentage of oxygen saturation in hemoglobin.

Answer 2

Explanation:

As altitude increases, pressure decreases and the air becomes 'thinner'. Higher pressure at sea level keeps oxygen molecules compressed together in air, so it is easier for us to breathe the amount we need in just one breath.
