Altitude sickness, locally known in Peru as soroche, is the body’s natural physiological response to reduced atmospheric pressure and lower oxygen levels at high elevations. The historical city of Cusco sits at 3,400 meters (11,150 feet) above sea level, and certain mountain passes on the Inca Trail exceed 4,200 meters (13,800 feet). To ensure your Andean journey is comfortable and trouble-free, we have compiled the 10 most effective tips to prevent and manage soroche.
1. Take Time to Rest and Acclimate First
Upon arriving in Cusco by plane or bus, refrain from strenuous physical activity during your first 24 to 48 hours. Give your body time to adapt naturally. A relaxed walking tour around Cusco’s historic plaza is an ideal way to begin.
2. Stay Constantly Hydrated
High-altitude mountain air is very dry, and faster breathing increases fluid loss. Drink plenty of fresh water (2 to 3 liters daily) and avoid alcoholic or sugary beverages during your initial days.
3. Eat Light, Easily Digestible Meals
Digestion slows down noticeably at high elevations. During your first days in Cusco, choose light soups, complex carbohydrates, and vegetables, avoiding heavy meats or greasy food in the evening.
4. Sip Traditional Coca Tea
Coca leaf tea (mate de coca) is an ancient Andean remedy used since Inca times. It stimulates respiration, boosts oxygen absorption, and eases mild headaches. Enjoy a cup every morning.
5. Avoid Alcohol and Tobacco
Both alcohol and smoking act as dehydrating agents and respiratory suppressants, which can significantly worsen altitude sickness symptoms.
6. Pace Yourself on Hikes
When walking around archaeological sites like Sacsayhuaman or climbing steps, maintain a steady, slow pace. Listen to your body and take regular resting breaks.
7. Consult Your Doctor About Preventative Medication
If you are sensitive to altitude changes, ask your physician about Acetazolamide (Diamox) or local over-the-counter remedies like Sorojchi Pills before your trip.
8. Consider Staying in the Sacred Valley First
Towns in the Sacred Valley (such as Ollantaytambo or Urubamba) sit at lower elevations (around 2,800 meters / 9,180 feet) than Cusco. Spending your first nights there allows for a gradual altitude transition.
9. Get Adequate Sleep
Prioritize 7 to 8 hours of restful sleep every night. Proper sleep supports your cardiovascular system and speeds up acclimatization.
10. Use Supplemental Oxygen if Needed
Reputable tour operators and quality hotels in Cusco provide emergency oxygen canisters. Inhaling oxygen for a few minutes offers immediate relief for headaches or shortness of breath.
