Nestled in the Andes Mountains, Cusco is a city rich with history and culture, serving as the gateway to the Sacred Valley and the iconic Machu Picchu. Its cobblestone streets and vibrant markets are bustling with the legacies of the Inca Empire and colonial Spanish architecture. This rich tapestry of past and present makes Cusco an irresistible destination for travelers seeking both adventure and cultural enrichment. However, its high altitude can pose a significant challenge for visitors unaccustomed to such elevations.

Altitude sickness, or “soroche” as it’s known locally, is a common ailment due to Cusco’s elevation of 3,399 meters (11,152 feet) above sea level. This condition can affect anyone, regardless of age or fitness level, and can turn an otherwise exciting trip into an uncomfortable experience. In this article, we explore how you can prevent altitude sickness in Cusco, utilizing both natural and medical remedies, ensuring your journey remains as enjoyable and memorable as possible.
Altitude sickness occurs when you ascend to high altitudes too quickly, and your body struggles to adapt to the lower levels of oxygen. As you climb higher, the air becomes thinner, meaning there are fewer oxygen molecules available in each breath. This can lead to a range of symptoms as your body attempts to adjust to these new conditions.

Symptoms can range from mild, such as headaches and dizziness, to more severe, including nausea and difficulty breathing. It’s important to understand that altitude sickness can escalate quickly if not addressed, potentially leading to more serious conditions like high altitude pulmonary edema (HAPE) or high altitude cerebral edema (HACE). Being informed about the symptoms and how to manage them is essential for a safe and enjoyable trip.
Recognizing these symptoms early is crucial to preventing more severe forms of altitude sickness. If you notice any of these signs, it’s important to rest and allow your body time to adjust. Ignoring symptoms can lead to a worsening condition, making it harder to recover quickly. Monitoring yourself and your travel companions is vital, especially in the first few days of your stay in Cusco.

Before embarking on your journey to Cusco, it’s essential to prepare your body for the change in altitude. This preparation can significantly reduce the risk of experiencing altitude sickness and make your acclimatization process smoother. A well-planned approach can also enhance your overall travel experience by allowing you to enjoy Cusco’s attractions without the discomfort of altitude-related symptoms.
One of the best ways to prevent altitude sickness is to allow your body time to acclimatize gradually. Spend a few days at an intermediate altitude before heading to Cusco. For example, you can stay in the Sacred Valley, which is lower in elevation than Cusco, to help your body adjust. This gradual approach gives your body time to increase red blood cell production, enhancing oxygen delivery to your muscles and organs.
Besides staying in the Sacred Valley, consider scheduling activities that don’t require intense physical exertion during your first few days. This gives your body the chance to adapt without additional stress. Enjoy leisurely walks and explore local cultural sites, allowing you to acclimatize while still immersing yourself in the rich history of the area.
Staying hydrated is key to combating altitude sickness. Drink plenty of water before and during your stay in Cusco. Proper hydration helps maintain blood volume and circulation, which are crucial for adapting to high altitudes. Avoid excessive consumption of alcohol and caffeine, as these can lead to dehydration and exacerbate symptoms.
Additionally, maintain a balanced diet rich in carbohydrates, which can help increase your energy levels and aid in acclimatization. Carbohydrates require less oxygen to metabolize, making them an efficient source of energy at high altitudes. Incorporate foods like fruits, vegetables, and whole grains into your meals to support your body’s adjustment process. Eating smaller, more frequent meals can also help maintain energy levels and prevent digestive discomfort.
The indigenous cultures of the Andes have long relied on natural remedies to cope with high altitudes. These traditional methods have been passed down through generations and are widely used by locals and travelers alike. They offer a holistic approach to managing altitude sickness, utilizing the natural resources available in the region.

Coca leaves have been used for centuries by the Andean people to alleviate symptoms of altitude sickness. You can chew the leaves directly or steep them in hot water to make coca tea. Both methods can help boost oxygen intake and reduce symptoms like headaches and fatigue. The active compounds in coca leaves stimulate respiratory function, enhancing the body’s ability to absorb oxygen.
In addition to its effects on altitude sickness, coca tea is a cultural experience in itself, often shared among locals and travelers as a gesture of hospitality. While coca leaves are legal and commonly used in Peru, it’s important to note that they are restricted in some other countries, so plan accordingly if you intend to bring any back from your trip.
Muña is another traditional remedy. This mint-like herb is known for its digestive and respiratory benefits. Drinking muña tea can help soothe your stomach and improve breathing, making it a popular choice for travelers in the region. The aromatic properties of muña can also provide a calming effect, which is beneficial when adjusting to high altitude.
Muña can be found in local markets and is often available in tea bags or as dried leaves. It’s a versatile remedy that can also be used in cooking to add flavor to dishes while providing health benefits. Including muña in your daily routine while in Cusco can offer a natural way to support your body’s adaptation to altitude.

In addition to natural remedies, there are medical options available to prevent and treat altitude sickness. These options can be particularly helpful for those who have a history of altitude sickness or who are planning a rapid ascent to high altitudes. Consulting with a healthcare professional before your trip can provide guidance on the best preventive measures for your specific needs.
Acetazolamide is a medication that helps your body adjust to high altitudes more quickly. It works by stimulating breathing, which increases oxygen levels in your blood. This medication is often used as a preventive measure and can be started a day before ascent and continued for the first few days at high altitude. Consult your doctor before your trip to see if this medication is suitable for you.
It’s important to note that while acetazolamide can be effective in preventing altitude sickness, it may have side effects such as tingling in the fingers and toes or increased urination. Discuss these potential effects with your doctor and ensure you understand how to use the medication properly.
In cases where symptoms become more severe, oxygen therapy may be necessary. Many hotels in Cusco city offer oxygen tanks for guests experiencing altitude sickness. Breathing in supplemental oxygen can provide immediate relief by increasing the amount of oxygen available to your body. This can be particularly useful during the night when symptoms may worsen due to decreased respiratory rates during sleep.
For travelers with underlying health conditions or those who experience persistent symptoms despite other measures, oxygen therapy can be a vital tool in ensuring safety and comfort. Always inform hotel staff about any medical needs upon arrival to ensure that appropriate resources are available if required.
While acclimatizing, take the opportunity to explore Cusco’s rich cultural heritage. The city and its surroundings offer a wealth of activities that can be enjoyed at a leisurely pace, allowing you to absorb the history and beauty of the Andes without overexerting yourself.
Visit the ancient Inca ruins of Sacsayhuamán and the Qorikancha temple, both of which offer insights into the architectural prowess of the Inca civilization. These sites are accessible and provide a gentle introduction to the region’s history without requiring strenuous activity. As you wander through these archaeological wonders, take time to appreciate the intricate stonework and the cultural significance they hold.
Cusco itself is a UNESCO World Heritage Site, with its historic center offering a blend of Inca and colonial architecture. Stroll through the Plaza de Armas, visit local museums, and enjoy the vibrant atmosphere of the city while allowing your body to acclimatize. Exploring at a relaxed pace ensures you don’t miss the details that make Cusco a unique and captivating destination.
If you plan to hike the Inca Trail to Machu Picchu, remember to pace yourself. The trail can be demanding, especially at high altitudes. Hiring a local guide can enhance your experience, providing historical context and ensuring a safer journey. Guides are knowledgeable about the trail and can offer advice on how to manage your pace and handle any altitude-related challenges.
Consider choosing a longer itinerary with more gradual ascents, allowing additional time for acclimatization. This approach not only reduces the risk of altitude sickness but also gives you more time to appreciate the breathtaking landscapes and the rich biodiversity along the trail. Remember, the journey is as important as the destination, and taking it slow can lead to a more rewarding experience.
