Does the altitude affect you in Uyuni?
The Salar de Uyuni is located more than 3,600 meters above sea level, an altitude that can affect those who are not used to it. From dizziness and fatigue to difficulty sleeping, knowing how your body reacts is key to enjoying the trip without any problems.
In this guide, we will explore the effects of altitude in Uyuni and how to prevent them.
What is this altitude sickness?
Altitude sickness (also called soroche or acute mountain sickness) is a set of symptoms that appear when a person goes up to high places (generally above 2,500 meters above sea level) and their body does not adapt quickly to the lower amount of oxygen.
Why does it happen?
At higher altitudes, atmospheric pressure decreases, meaning less oxygen is available with each breath. Although the percentage of oxygen in the air remains the same, less oxygen reaches the lungs and blood.
When a person ascends rapidly, the body doesn’t have enough time to adapt . Normally, the body needs several days to:
Increase breathing and heart rate.
Produce more red blood cells, which carry oxygen.
Adjust the functioning of the brain and other organs to the lowest amount of oxygen.
If these changes do not occur in time, the brain and other organs receive less oxygen than necessary , causing the symptoms of altitude sickness such as headache, dizziness, nausea, and fatigue.
Who does it affect?
The Salar de Uyuni, located in Bolivia, sits at 3,656 meters above sea level . This altitude can cause altitude sickness , especially in people unaccustomed to high altitudes. Understanding the symptoms, risks, and ways to adapt is key to enjoying your trip and preventing altitude sickness in Uyuni.
