Bolivia's High-Altitude Haven: Exploring The Rarefied Air

Bolivia is known for its soaring heights, with much of the country's highlands situated more than 3,000 meters (10,000 feet) above sea level. The capital city of La Paz sits at an elevation of 3,640 meters, making it the highest administrative capital in the world. The city is located in a canyon, resembling a bowl within the Bolivian altiplano, a high-altitude plain that dominates the southern and western regions of the country. The surrounding region, including the Andes Mountains, reaches even higher altitudes, with the nearby peak of Huayna Potosi towering at 6,088 meters.

Due to these extreme elevations, travelers to Bolivia often experience altitude sickness, also known as soroche or Acute Mountain Sickness (AMS). Symptoms can include shortness of breath, headache, nausea, lethargy, and loss of appetite. In more severe cases, altitude sickness can lead to High Altitude Pulmonary Edema (HAPE) or High Altitude Cerebral Edema (HACE), which can be life-threatening. Therefore, it is crucial for visitors to gradually adjust to the high altitudes and be aware of the symptoms and risks associated with altitude sickness.

La Paz is the world's highest administrative capital city

La Paz, Bolivia, is the world's highest administrative capital city, sitting at a lofty 3,640–3,650 metres (11,942–11,975 feet) above sea level. It is perched within a canyon carved by the Choqueyapu River in west-central Bolivia, about 68 km (42 miles) southeast of the iconic Lake Titicaca.

La Paz's elevation places it in the "very high altitude" category, which ranges from 3,500 to 5,500 metres (11,500–18,000 feet) above sea level. This altitude has a profound impact on the lives of its residents and visitors alike. The thin air can cause altitude sickness, also known as acute mountain sickness (AMS), with symptoms such as headaches, loss of appetite, sleep disturbances, weakness, and dizziness. Even cooking is affected by the altitude, as water boils at a lower temperature, requiring adjustments to cooking methods.

Despite the challenges, La Paz is a bustling metropolis with a population of over 750,000 people as of 2024. It is the seat of the Bolivian government, housing the Palacio Quemado (presidential palace) and the Plurinational Legislative Assembly. The city boasts impressive colonial-era landmarks, such as the San Francisco Church and the Metropolitan Cathedral, as well as modern developments like the Mi Teleferico cable car system, which facilitates transportation between La Paz and the neighbouring city of El Alto.

La Paz stands out for its dense urban fabric, with countless houses and brick-red buildings clinging to the steep canyon walls. The city's topography, characterised by its bowl-like shape and surrounding high mountains, offers breathtaking views. Overlooking La Paz is the majestic triple-peaked Illimani, which rises to an altitude of 6,402 metres (21,004 feet) and is perpetually snow-capped.

The altitude also influences the social dynamics of the city. More affluent residents tend to occupy the lower, central areas of La Paz, while middle-class residents reside in high-rise condos closer to the city centre. The lower-income population typically inhabits makeshift brick houses in the surrounding hills, showcasing the impact of altitude on the city's class structure.

Altitude sickness can be prevented by drinking coca tea

Bolivia is home to some of the world's highest cities, with La Paz, the administrative capital, sitting at 3,640 metres above sea level. The metropolitan area of La Paz includes the even higher city of El Alto, which sits at 4,150 metres. Bolivia's high altitude makes it infamous among travellers for causing altitude sickness, also known as acute mountain sickness (AMS).

AMS can occur at high altitudes where there is less oxygen available, and symptoms include headache, fatigue, loss of appetite, nausea, insomnia, dizziness, and general malaise. In rare cases, AMS can develop into High-Altitude Pulmonary Edema (HAPE) or High-Altitude Cerebral Edema (HACE), which can be fatal if a person does not descend to a lower altitude.

One way that people try to prevent and treat AMS is by consuming coca leaves or coca tea, which are widely available in Bolivia. Coca leaves are native to the Andean region of South America and have been used for thousands of years by indigenous peoples, including the Incas, who considered them sacred. Today, coca leaves are an important part of Andean culture and are often chewed or made into tea to relieve the symptoms of mild altitude sickness.

While there is limited scientific evidence on the effectiveness of coca leaves for AMS, many travellers and hikers have found them to be effective. Coca leaves are believed to increase energy levels and reduce pain and dizziness, making them a popular remedy for the fatigue and dizziness associated with altitude sickness.

In addition to drinking coca tea, there are several other measures that can be taken to prevent AMS, including allowing more time to acclimatize, climbing high and sleeping low, taking altitude sickness medications, staying hydrated, and avoiding alcohol and sleeping pills.

Symptoms of altitude sickness include headache, nausea, lethargy and loss of appetite

Bolivia is home to some of the world's highest cities. La Paz, the country's administrative capital, sits at 3,640 metres above sea level, while the city of El Alto, which sits at 4,150 metres, is even higher. Because of this, Bolivia is infamous among travellers for causing altitude sickness.

Altitude sickness, or acute mountain sickness (AMS), is caused by ascending too rapidly, which doesn't allow the body enough time to adjust to the reduced oxygen levels and changes in air pressure. Symptoms of altitude sickness include headache, nausea, lethargy and loss of appetite.

Headaches are the most common symptom of altitude sickness. They usually occur 2-12 hours after arriving at a high elevation and can feel like a hangover. Other symptoms include dizziness, muscle aches, nausea, loss of appetite, trouble sleeping, weakness, and/or dizziness. In more severe cases, individuals may experience vomiting, irrational behaviour, and a tight chest.

If you have a moderate case of altitude sickness, your symptoms may feel more intense and will not improve with over-the-counter medications. Instead of feeling better, you will feel worse over time. You will experience more shortness of breath and fatigue, as well as a loss of coordination and trouble walking.

If you develop a severe form of altitude sickness, known as high-altitude pulmonary edema (HAPE) or high-altitude cerebral edema (HACE), you may experience shortness of breath even while resting, a persistent cough, and a tightening in your chest. HAPE and HACE are life-threatening conditions that require immediate medical attention.

Drinking alcohol at high altitudes can be dangerous

Bolivia is a country in South America with a high average altitude. The country's administrative capital, La Paz, is located at 3,640 meters above sea level, making it the highest administrative capital in the world. The metropolitan area of La Paz, El Alto, is even higher, at 4,150 meters.

Due to its high altitude, travelers to Bolivia often experience altitude sickness, also known as acute mountain sickness (AMS). The thin air and reduced oxygen levels at high altitudes can cause a range of symptoms, including headaches, dizziness, weakness, and trouble sleeping.

• Dehydration: Alcohol is a diuretic, causing the body to lose fluids. At high altitudes, the body is already prone to dehydration due to the lower oxygen levels and drier air. Consuming alcohol can further dehydrate the body, leading to a decrease in blood oxygen saturation levels, which is a contributing factor to altitude sickness.
• Impaired Judgment and Coordination: The reduced oxygen levels at high altitudes can cause people to get drunk faster, leading to impaired judgment and coordination. This can lead to risky decisions such as driving under the influence or engaging in activities with increased risks for injury or death.
• Heightened Risk of Nausea, Vomiting, Headaches, and Lightheadedness: The combination of alcohol and high altitudes can result in a higher likelihood of experiencing these unpleasant symptoms.
• Exaggerated Effects: While recent studies have shown that alcohol does not affect the body differently at high altitudes compared to sea level, the overall experience of drinking at high altitudes can be more intense. The dehydration, impaired judgment, and other symptoms associated with alcohol consumption are often more pronounced and can affect one's physical and cognitive well-being.
• Altitude Sickness: Alcohol can worsen the symptoms of altitude sickness. The reduced air pressure and oxygen levels at high altitudes affect the rate at which oxygen moves from the lungs into the bloodstream. This means that the body takes longer to break down and process alcohol, leading to a decreased tolerance.

It is important to take precautions when drinking at high altitudes. Staying hydrated, pacing oneself, and being aware of alcohol consumption are essential to prevent adverse effects. Additionally, it is crucial to plan ahead and designate a sober driver or utilize public transportation when drinking at high elevations.

The city of El Alto is even higher than La Paz

Bolivia is a country in South America that is known for its high altitude. The average altitude in Bolivia is roughly 5,100 meters above sea level. The country's capital city, La Paz, is located at 3,640 meters above sea level, making it the highest administrative capital city in the world. However, the city of El Alto, which is located adjacent to La Paz, sits at an even higher altitude.

El Alto is the second-largest city in Bolivia and is one of the fastest-growing urban centers in the country. It has an estimated population of over 900,000 people and is the highest major city in the world, with an average elevation of 4,000 meters (13,123 feet) above sea level. Some sources put the altitude even higher, at 4,150 meters or 4,300 meters. The city's name, "El Alto," translates to "The Heights" in English, reflecting its high elevation.

The metropolitan area formed by La Paz and El Alto is the most populous urban area in Bolivia, with a combined population of about 2.2 million people. The two cities are connected by a cable car system, known as Mi Teleferico, which is the longest urban cable car system in the world. This system has significantly improved transportation between the two cities and has cut down on traffic and fuel costs.

The high altitude of El Alto has some notable impacts on the lives of its residents. The city's airport, El Alto International Airport, is the world's highest international airport. The thin air at this altitude affects aircraft takeoffs, requiring longer runways. Additionally, the altitude can cause health issues for visitors, including dizziness and breathlessness. It is recommended that travelers spend time in lower-elevation cities to acclimatize before visiting El Alto.

The altitude also affects everyday activities such as cooking. For example, the lack of oxygen impacts the rising process in bread-making, and water boils at a lower temperature, impacting the cooking of rice, potatoes, and wheat.

Despite the challenges posed by its high altitude, El Alto has experienced rapid development and economic growth. The city has a distinct architectural style, known as Neo-Andean, and has seen a boom in the construction of flashy mansions and modern infrastructure. However, there are also significant challenges with substandard infrastructure and utilities, particularly in the outlying areas.
