Nestled high in the Peruvian Andes, Cusco often dazzles travelers with its rich history and breathtaking landscapes. However, altitude sickness in Cusco is a challenge. Many tourists, eager to explore this ancient Incan capital, find themselves battling this unexpected foe.
Altitude sickness isn’t limited to extreme mountaineers or high-altitude athletes. Anyone traveling to places like Cusco can experience its unsettling symptoms. Thankfully, with the right knowledge and precautions, it can often be prevented.
Why does altitude sickness occur?
When we travel to high altitudes, like Cusco’s 3,400 meters (11,150 feet) or even higher altitudes such as those encountered on the Inca Trail or the Salkantay Trek, the atmospheric pressure drops, and the oxygen in the air becomes less available. Our bodies are accustomed to higher concentrations of oxygen, which is why our breathing and circulation are directly affected. The lungs take in less oxygen at high altitudes, and the heart works harder to circulate blood, trying to compensate for the deficiency.
At sea level, the air contains about 21% oxygen, but as you ascend, this percentage remains the same, but the air density decreases. This reduction in air pressure and oxygen availability at high altitudes places significant stress on the body, leading to hypoxia—a condition in which the body doesn’t get enough oxygen. Altitude sickness occurs as a result of the body struggling to adjust to these conditions.

Types of altitude sickness
There are different forms of altitude sickness, depending on severity:
- Acute Mountain Sickness (AMS): This is the most common and mild form of altitude sickness. It can cause symptoms such as headaches, dizziness, nausea, fatigue, and trouble sleeping. AMS typically occurs when ascending too quickly without allowing the body time to acclimatize. It’s the least dangerous form but should still be taken seriously.
- High Altitude Pulmonary Edema (HAPE): This is a more serious form of altitude sickness that involves fluid accumulation in the lungs, making it hard to breathe. It is a life-threatening condition and requires immediate descent to lower altitudes and medical intervention.
- High Altitude Cerebral Edema (HACE): A severe form of altitude sickness affecting the brain, HACE involves swelling of the brain and can lead to confusion, loss of coordination, and even unconsciousness. This is also a life-threatening emergency requiring immediate medical help and descent.
Science behind altitude sickness
When exposed to high altitudes, your body undergoes a process called acclimatization, which involves adjusting to lower oxygen levels. The body increases its production of erythropoietin (EPO), a hormone that stimulates the production of red blood cells. Red blood cells are responsible for transporting oxygen throughout the body, and by having more of them, the body can carry out its functions more efficiently.
However, the process of acclimatization is gradual, and the body needs time to produce more red blood cells and adjust to the low-oxygen environment. In the meantime, symptoms like headaches and fatigue can occur as the body tries to cope with this deficiency. This is why it’s important to gradually increase altitude—this allows the body time to make these physiological adjustments.

The Role of Coca Leaves
In the Andes, Coca Leaf have been used for centuries to alleviate symptoms of altitude sickness. While not a cure, the leaves contain alkaloids that help reduce the effects of low oxygen levels. Coca leaves have mild stimulant properties that can increase energy and decrease appetite, helping travelers to combat fatigue and nausea. They also promote blood circulation and can have a mild pain-relieving effect, which is why coca leaf tea is commonly consumed at high altitudes in places like Cusco.
It’s worth noting that while the leaves themselves are legal in Peru, coca-based products outside the region may be subject to international regulations, as they can be processed into substances like cocaine. Therefore, when in Peru, it’s safe to consume coca tea and other traditional remedies, but be aware of regulations in your home country regarding coca-derived products.
Another scenario where altitude’s effects are felt is the Choquequirao trek. This challenging hike takes adventurers through varying altitudes. Some sections ascend to heights where oxygen becomes notably scarcer. Again, Altitude Sickness in Cusco and surrounding treks can catch travelers off-guard.
Understanding the science helps us prepare and take precautions. Awareness of our body’s needs and limitations is key. And in places like Cusco, respecting altitude is essential for a memorable, positive experience.
Recognizing early symptoms: Stay alert and informed
Visiting high-altitude destinations like Cusco is thrilling. However, being informed about potential health risks is crucial. Altitude Sickness in Cusco is not uncommon among visitors.
One of the first symptoms is often a mild headache. Some describe it as a persistent, dull ache. This can be accompanied by fatigue, even if you’ve had ample rest. Another sign is difficulty sleeping, which might seem ironic given the previous symptom. Dizziness and light-headedness are also common complaints. You might also feel short of breath during activities you’d typically find easy.
The Salkantay Trek, famous for its panoramic views, is another place where symptoms might manifest. The trek has varying altitudes, challenging even seasoned hikers. Being aware of your body’s reactions throughout the journey is essential.
Nausea is another symptom not to ignore. In some cases, it can escalate to vomiting. If you experience these symptoms, it’s crucial to descend to a lower altitude. Persistent symptoms or worsening conditions need immediate attention.
Experiencing Altitude Sickness in Cusco doesn’t mean your trip is ruined. Early recognition is the key to managing it. If symptoms appear, don’t push yourself too hard. Instead, rest, stay hydrated, and seek medical advice if.

Prevention and remedies: How to safeguard your health at high elevations
Embarking on high-altitude adventures is exhilarating. Yet, safeguarding your health during these ventures is paramount. Knowing preventive measures and remedies is your best defense.
Start with acclimatization. Spend a few days at moderate altitudes before ascending higher. This gradual adjustment can significantly reduce risks. Next, stay hydrated. Drink plenty of water, even if you aren’t feeling thirsty. Dehydration can exacerbate altitude sickness symptoms. Also, avoid alcohol and caffeine in the first 48 hours at altitude. Both can cause dehydration and disrupt sleep.
Eating a balanced diet is crucial. Focus on consuming complex carbohydrates like whole grains. They provide sustained energy and are easier to digest. Oxygen can be scarce at high altitudes. Some travelers opt for portable oxygen canisters. These can offer relief during acute bouts of breathlessness.
Many locals recommend coca leaves. Whether chewed or brewed into tea, they’re believed to alleviate symptoms. However, always ensure you’re sourcing them legally and responsibly. Medications are available, such as acetazolamide, that aid acclimatization. Consult with a healthcare professional before using any medication.
Pay attention to your body. If symptoms arise, don’t hesitate to descend to a lower altitude. Often, this alone provides relief. Remember, the goal is to enjoy your journey, not push through discomfort.
When to seek help: Dealing with serious symptoms
While most cases of altitude sickness can be managed with rest and acclimatization, in severe cases, medical attention is necessary. If you experience confusion, extreme weakness, difficulty walking, or a persistent cough or difficulty breathing, these could be signs of HAPE or HACE, which require immediate descent to a lower altitude and urgent medical care. Always keep in mind that the higher you go, the quicker altitude sickness symptoms can escalate.
Enjoying Cusco and its treks safely
To summarize, Cusco is an incredibly rewarding destination with its ancient ruins, vibrant culture, and stunning landscapes. While altitude sickness can be a challenge for some, understanding how the body reacts to high altitudes and following precautions can help minimize risks. In conclusion, your high-altitude experience can be both safe and enjoyable. Armed with knowledge and precautions, you’re ready. Consider taking on challenges like the Salkantay Trekking or the Classic Inca Trail. Embrace the adventure, but always prioritize your well-being.
