Question

Why does the rate of breathing increase while walking uphill at a normal pace in the mountains? Give two reasons.

Answer 1

The rate of breathing increases while climbing uphill because the atmosphere is very thin at high altitudes and hence the amount of oxygen present in the air deceases. And our body needs more oxygen than what it is getting in normal breathing rate. So to increase the amount of oxygen, the rate of breathing is increased.

Answer 2

Answer :

The rate of breathing increases when walking above normal speed in the mountains. Because as the climbing up, the rate of breathing increases as the atmosphere is very thin at very high altitude and hence the amount of oxygen present in the air decreases.

Human body needs more oxygen than normal breathing rate. So to increase the amount of oxygen, the breathing rate is also increases.
