Many people travel to Morocco for its majestic mountain ranges and hiking adventures, accessible to trekkers of all abilities. Trekking the High Atlas Mountains offers a particular allure for adventurous hikers, with its highest peaks around 13,000 feet and more than 400 of them reaching almost 10,000 feet.
Though exhilarating, such heights introduce the risk of altitude sickness. Recognizing the onset of altitude sickness and knowing how to manage it are keys to a safe and enjoyable mountain journey.
What is altitude sickness?
As you ascend to higher altitudes, the concentration of oxygen in the air gradually decreases, which can make it challenging for your body to get the oxygen it needs to function properly. Regardless of your fitness level, climbing to 8,000 feet or higher too quickly can initiate altitude sickness with any of the following symptoms:
- Throbbing headaches
- Loss of appetite
- Nausea (even vomiting)
- Fatigue
- Dizziness
- Insomnia
Some people compare altitude sickness to a hangover or a developing flu. If ignored, the condition can be fatal. However, when properly managed, the symptoms of altitude sickness typically fade as your body adjusts to the conditions.
Managing altitude sickness.
If your body isn’t used to high altitudes, you’re likely to experience symptoms of altitude sickness to some extent, despite your best efforts to prevent it. Fortunately, taking preventative measures before symptoms set in can help ensure that its effects remain mild and that recovery comes swiftly.
Climbing gradually, with several breaks along the way, is a reliable method for minimizing the condition’s effects. If you intend to trek higher than 8,000 feet, plan for a day or two of rest every 2,000 feet beyond that point.
Other tips for prevention include:
- Stay hydrated
- Avoid alcohol
- Eat meals high in carbohydrates
- Sleep at an altitude below 8,000 feet (especially if the day’s activities take place at a higher point)
If altitude sickness strikes, the most effective remedy is to move down to a lower altitude and rest. Drink enough water to ensure that you’re sufficiently hydrated, and don’t climb back up the mountain until the symptoms are gone … even if it takes several hours. Noticing any symptoms early and responding immediately helps ensure a full recovery.
If symptoms feel mild, simply resting where you are and allowing your body to adjust may allow the effects to fade away. However, beware of underestimating or neglecting symptoms, as they will only worsen if you continue to climb without the extra rest your body demands.
At worst, altitude sickness can escalate from uncomfortable to fatal. If ignored, the condition can lead to fluid buildup in the lungs and swelling of the brain. Confusion, inability to walk straight and blue lips or fingernails all point to severe altitude sickness calling for immediate medical attention.
Be safe and enjoy.
While talk of potentially fatal conditions can make high-altitude trekking seem intimidating, diligent prevention and an immediate response to symptoms generally keeps altitude sickness in check. So take that hike, admire the panoramic views and remember to snap plenty of photos.
