Why do tribes who live in high altitude of Himalayas experience discomfort in respiration? How do they get adapted to survive in such a situation?

Explanation

### Step-by-Step Solution:

1. **Understanding High Altitude Conditions**:
- At high altitudes, such as in the Himalayas, the atmospheric pressure is lower compared to sea level. This means that the air is less dense, and there is a lower concentration of oxygen available for respiration.

2. **Discomfort in Respiration**:
- The tribes living in these high-altitude areas experience discomfort in respiration primarily due to the decreased availability of oxygen. As altitude increases, the partial pressure of oxygen decreases, making it harder for the body to obtain the necessary oxygen for metabolic processes.
