Introduction
Cusco, the ancient capital of the Inca Empire, sits at an impressive 3,400 meters (11,150 feet) above sea level. While its cobblestone streets and colonial architecture attract millions of visitors each year, the altitude can be a challenge for those not accustomed to high elevations. The condition commonly known as "soroche" or acute mountain sickness (AMS) affects many travelers, but with the right preparation, you can minimize its effects and enjoy your trip to the fullest.
In this guide, you'll find practical advice, natural remedies, and essential recommendations to prevent and relieve altitude sickness in Cusco. Whether you're planning a visit to Machu Picchu, exploring the Sacred Valley, or immersing yourself in the city's rich history, these tips will help you feel your best from the moment you arrive.
📌 Key fact: Altitude sickness occurs when your body struggles to adapt to the lower oxygen levels at high elevations. Symptoms typically appear within 6 to 24 hours of arrival and can include headache, fatigue, nausea, dizziness, and shortness of breath.
Understanding Altitude Sickness: Symptoms and Causes
Before learning how to prevent altitude sickness, it's important to recognize its symptoms. The body's response to high altitude varies from person to person, and even fit individuals can experience discomfort. The most common symptoms include:
- Headache: Often the first and most common symptom, ranging from mild to severe.
- Fatigue and weakness: Feeling unusually tired even after minimal exertion.
- Dizziness and lightheadedness: A sense of imbalance or feeling faint.
- Nausea and loss of appetite: Stomach discomfort that can lead to vomiting.
- Shortness of breath: Difficulty catching your breath during normal activities.
- Sleep disturbances: Insomnia or frequent waking during the night.
These symptoms are caused by the lower oxygen pressure at high altitudes, which forces your body to work harder to oxygenate your blood. The good news is that with proper acclimatization, most people adapt within 1 to 3 days.

Natural Remedies for Altitude Sickness
These traditional Andean remedies are widely used by locals and travelers alike to prevent and relieve altitude symptoms.

Instead of rushing to visit all the sites, plan a relaxed itinerary for the first two days to allow acclimatization.
Altitude can affect sleep. Keep your room ventilated, avoid heavy meals before bed, and consider using a humidifier.
Practice deep breathing exercises to increase oxygen intake. Inhale slowly through your nose and exhale through your mouth.
