At Khardungla Pass, the oxygen level is significantly reduced, effectively being approximately 50% of what it is at sea level. This substantial drop in oxygen availability at such high altitudes makes breathing challenging and necessitates proper precautions for visitors.
Understanding Oxygen Availability at High Altitudes
While the percentage of oxygen in the air (approximately 21%) remains constant at different altitudes, the atmospheric pressure decreases significantly as you ascend. This reduction in atmospheric pressure means there are fewer oxygen molecules available per breath, leading to a lower partial pressure of oxygen. At Khardungla Pass, which stands at an elevation of 5,359 meters (17,582 feet), the air pressure is roughly half of that at sea level, directly impacting the amount of oxygen your body can take in.
Here's a comparison to illustrate the difference:
| Location | Approximate Altitude | Relative Oxygen Availability | Impact on Breathing |
|---|---|---|---|
| Sea Level | 0 meters (0 feet) | 100% | Normal |
| Khardungla Pass | 5,359 meters (17,582 feet) | Approximately 50% | Difficult |
Impact of Reduced Oxygen on the Human Body
The decreased oxygen availability at Khardungla Pass can lead to various symptoms of altitude sickness, also known as Acute Mountain Sickness (AMS). Common symptoms include:
- Headache
- Nausea and vomiting
- Dizziness
- Fatigue
- Shortness of breath, even at rest
- Difficulty sleeping
For some individuals, especially those with pre-existing health conditions, the effects can be severe, potentially leading to High-Altitude Pulmonary Edema (HAPE) or High-Altitude Cerebral Edema (HACE), which are life-threatening conditions.
Essential Precautions for Visiting Khardungla Pass
Given the challenging oxygen levels, it is crucial to take proper precautions when planning a visit to Khardungla Pass to ensure safety and minimize health risks. Preparedness is key for a comfortable and safe journey to such high altitudes.
Here are some essential considerations and items to carry:
- Acclimatization: Spend a few days in Leh (which is at a lower altitude than Khardungla) before attempting to ascend further. This allows your body to gradually adjust to the reduced oxygen levels.
- Stay Hydrated: Drink plenty of fluids, especially water, to combat dehydration, which can worsen altitude sickness symptoms. Avoid alcohol and excessive caffeine.
- Gradual Ascent: If possible, ascend gradually, taking breaks. Avoid strenuous activities immediately upon arrival at high altitudes.
- Warm Clothing: The weather at Khardungla Pass can be extremely cold and windy. Layered, warm, and windproof clothing is essential.
- Portable Oxygen Cylinders: Carry small portable oxygen cylinders as a backup for immediate relief if you experience severe breathlessness.
- Medicines: Consult your doctor about preventive medications for altitude sickness, such as Acetazolamide (Diamox). Carry basic first-aid supplies and any personal medications.
- Light Baggage: Avoid carrying heavy loads that can add strain.
- Sun Protection: High altitudes mean increased UV radiation. Use high-SPF sunscreen, sunglasses, and hats.
- Monitor Symptoms: Pay close attention to any signs of altitude sickness. If symptoms worsen, descend to a lower altitude immediately.
