When we go to high altitude places (>3500m) we experience altitude sickness. Its symptoms include nausea, fatigue and heart palpitations. It is due to the low atmospheric pressure of high altitudes due to which body does not get enough oxygen. The body compensates low oxygen availability by increasing red blood cell production, decreasing the binding capacity of haemoglobin and by increasing breathing rate.

Understanding Altitude Sickness
When an inhabitant from Varanasi travels to Rohtang, which is at a significantly higher altitude, they may experience various symptoms due to the change in environmental conditions. Here’s a breakdown of why the correct answer is option 'D' – all of these.
Altitude Sickness
- Definition: Altitude sickness, or acute mountain sickness (AMS), occurs due to reduced oxygen availability at high elevations.
- Symptoms: Common symptoms include nausea, fatigue, and heart palpitations, which the individual is experiencing.
RBC Count
- Importance of RBCs: Red blood cells (RBCs) carry oxygen throughout the body.
- Impact of Altitude: At higher altitudes, the thinner air can lead to lower oxygen levels, which may exacerbate symptoms if an individual's RBC count is not sufficient to meet oxygen demands.
Atmospheric Pressure
- Low Pressure Effects: Atmospheric pressure decreases with altitude, leading to reduced oxygen availability.
- Physiological Response: The body may react to this low pressure by increasing heart rate and causing fatigue and nausea as it struggles to obtain adequate oxygen.
Conclusion
In summary, the inhabitant's symptoms are a result of altitude sickness, potentially worsened by a lower RBC count and the effects of being in a low atmospheric pressure environment. Thus, all factors contribute to the experience of discomfort at high altitudes, confirming that option 'D' is indeed correct.
