How to avoid altitude sickness while trekking

Some people are apprehensive of booking a trekking trip to high altitudes because they’re afraid they’ll suffer from altitude sickness. It is common, but don’t let this stop you from going on this once in a lifetime trek! Whether you’re going to Machu Picchu in Peru, Kilimanjaro, Everest or any other peak with significant altitude (the air is usually thinner above 8000ft or 2500m), you won’t know how your body will handle it until you’re there. But fear not, we’ve collected the best tips on how to avoid or minimise the symptoms.

Doctor: Speak to your doctor before going on your first high altitude trek. They’ll check that you’re all good to go and might recommend some medicines you can bring to reduce symptoms should they appear.

Acclimatise: Chances are if you’re trekking to very high altitudes, the town where you’re starting is also high in altitude. Take Cusco for example. Cusco is where you fly into when trekking to Machu Picchu and is, in fact, higher in altitude than Machu Picchu itself. Spend a day or two here so your body gets used to the thinner air. We also recommend spending a day here afterwards to not shock your body with the difference in altitude.

Hydration, hydration, hydration: Dehydration and altitude sickness have some of the same symptoms, such as lightheadedness and headaches. Don’t make it worse by suffering from both! You’ll also walk long distances, sometimes in hot weather, so water is key! Drink loads.

Breathe: Take deep breaths, especially if you’re feeling lightheaded, slow down (lie down if you have to) and take long, deep breaths.

Coca tea: (PERU only) coca leaves are said to be great for altitude sickness and nearly every hotel in Cusco offers it. Try to drink one cup a day (no more).

Oxishots: Just as the name suggests, Oxishots offer a shot of oxygen and can help reduce headaches and other altitude sickness symptoms. It costs about $15 and can definitely be worth a … shot.

Unless you’ve suffered from severe altitude sickness in the past, try not to let the fear of getting this keep you from going on these trips. Remember the guides in the area are experts and if you do get some symptoms you’re unlikely to be the only one on your tour that does. Just remember to take it easy before, acclimatise and you should be fine. Most of the time on these tours you’ll be too busy taking in the spectacular scenery you won't even think about the altitude.
