Navigating The Heights A Guide to Acclimating to High Altitudes

how to accilimate to high altitude


Stepping into the realm of high altitudes can be an exhilarating experience, offering breathtaking vistas and unique adventures. However, the thin air and reduced oxygen levels can pose challenges to our bodies, requiring a period of acclimatization. In this article, we will delve into the essential strategies to help you adapt and thrive in high-altitude environments.

Understanding High Altitude

High altitudes, typically starting at 8,000 feet (2,438 meters) above sea level, can trigger a series of physiological changes in our bodies due to lower air pressure and decreased oxygen availability. These changes include increased heart rate, deeper breathing, and the release of erythropoietin (EPO), a hormone that stimulates the production of red blood cells. While these adaptations aid in oxygen transport, they take time to develop fully.

Gradual Ascent

The key to successful acclimatization is a gradual ascent. Allow your body time to adjust to the changing conditions by ascending no more than 1,000 to 1,500 feet (305 to 457 meters) per day once above 8,000 feet. This measured pace gives your body the chance to adapt without becoming overwhelmed by the sudden reduction in oxygen levels.

Stay Hydrated

Proper hydration is paramount at high altitudes. As the air gets thinner, you tend to exhale more moisture with each breath, leading to increased fluid loss. Counteract this by drinking ample water throughout the day. Avoid excessive caffeine and alcohol, as they can contribute to dehydration.

Balanced Nutrition

Maintain a balanced and nutrient-rich diet to support your body’s energy needs during acclimatization. Focus on foods rich in carbohydrates, which provide a readily available source of energy. Incorporate lean proteins and foods high in iron and vitamin B12 to support red blood cell production.

Adequate Rest

Quality sleep is crucial for acclimatization. Listen to your body and prioritize rest, especially during the initial days at high altitude. If you experience difficulty sleeping due to the altitude, consider taking short naps during the day to supplement your rest.

Physical Activity

While moderate physical activity is recommended during acclimatization, avoid pushing your limits. Engage in light exercise and short hikes to encourage blood circulation without putting excessive strain on your body. Overexertion can lead to fatigue and hinder acclimatization.

Altitude Sickness

Altitude sickness, also known as acute mountain sickness (AMS), can affect individuals differently. Symptoms include headache, nausea, dizziness, and fatigue. If you experience these symptoms, it’s essential to descend to a lower altitude until you feel better. Severe cases of altitude sickness can escalate to high altitude pulmonary edema (HAPE) or high altitude cerebral edema (HACE), which are life-threatening conditions that require immediate medical attention.

Medication and Supplements

Consult a healthcare professional before taking any medication or supplements for altitude acclimatization. Acetazolamide, a prescription medication, can help alleviate symptoms of AMS by stimulating increased ventilation. Additionally, iron supplements can aid in red blood cell production. However, these should only be taken under medical supervision.

Local Remedies

Local communities often have traditional remedies to ease altitude-related discomfort. For instance, in the Andes, coca tea is believed to alleviate symptoms. While trying these remedies can be interesting, it’s vital to prioritize proven strategies and seek medical assistance if symptoms worsen.

Time for Acclimatization

It takes time for your body to fully adjust to high altitudes. Plan for a minimum of two to three days at moderate altitudes (around 8,000 to 10,000 feet) before ascending to higher elevations. During this time, your body will undergo the necessary adaptations to cope with reduced oxygen levels.


How long does it take to get acclimated to high altitude?

At altitude the air pressure is lower and this means there is less oxygen available to your body when you breathe. We need oxygen for our bodies to work properly. The process of your body adapting to the lower oxygen levels is called acclimatization and it takes about 3 to 5 days.

Who is prone to altitude sickness?

Anyone can get altitude sickness. Your age, sex and general health don’t seem to affect your risk. You may be at higher risk if you: Have a lung or heart condition: Your healthcare provider may recommend avoiding high altitudes if possible.


Embarking on a journey to high altitudes requires patience and a thoughtful approach. By respecting your body’s need for acclimatization and adhering to these guidelines, you can enhance your experience and minimize the risks associated with altitude-related illnesses. Remember, the journey itself is as important as reaching the summit, so take the time to savor the stunning landscapes and unique cultures that high-altitude regions have to offer.
