Many of Uttarakhand's most magical destinations — Kedarnath, Hemkund Sahib, Tungnath, Tapovan — sit above 3,500 metres, where thin air can trigger Acute Mountain Sickness (AMS). Understanding altitude sickness is essential for every Himalayan traveller, because it can affect anyone regardless of age or fitness.
What happens: At high altitude, lower oxygen levels strain the body. Mild AMS symptoms include headache, nausea, dizziness, fatigue, loss of appetite, and disturbed sleep — typically appearing 6–24 hours after ascent. Ignored, AMS can progress to dangerous conditions affecting the lungs or brain, which are medical emergencies.
Prevention is straightforward: Ascend gradually. Avoid flying or driving directly to high altitudes and immediately exerting yourself. Build in acclimatisation time — spend a night at intermediate altitudes (like Guptkashi before Kedarnath, or Ghangaria before Hemkund). On treks, follow the golden rule: climb high, sleep low.
Hydrate constantly. Drink 3–4 litres of water daily; dehydration mimics and worsens AMS. Avoid alcohol and smoking entirely at altitude, and limit caffeine.
Eat well and move slow. Carbohydrate-rich meals help; walk at a pace where you can hold a conversation. Pilgrims using ponies or helicopters to Kedarnath should still rest before darshan, as rapid ascent without walking removes natural acclimatisation.
If symptoms appear: Stop ascending. Rest, hydrate, and take paracetamol for headache. If symptoms worsen or persist beyond a day, descend immediately — descent is the only reliable cure. Medical posts operate along major pilgrimage routes; use them without hesitation. Consult your doctor before travel about preventive medication, especially if you have heart or lung conditions.
