Many trekkers heading to high altitude arrive with misconceptions that could put their lives at risk. Everest Live sat down with Dr. Sammy from Everest ER at the Everest Base Camp to set the record straight on some of the most dangerous high altitude myths circulating among climbers. Many of the myths they look at are specific to Everest and the Himalayas, but there’s still plenty that can be of use to any high-altitude hiker or adventurer.
Fitness does not protect you. No matter how much time you spend in the gym, altitude illness can affect anyone. Physical conditioning offers zero immunity from the effects of high elevation.
Sherpas are not immune either. While Sherpas historically showed some genetic advantages at altitude, those who have spent extended time at lower elevations in Kathmandu are just as susceptible as any foreign trekker, especially when ascending quickly.
Oxygen is not a workaround. Some trekkers assume they can simply breathe supplemental oxygen and push forward through symptoms. This is a dangerous misconception. Oxygen is a treatment for life-threatening conditions, not a tool to enable continued ascent, and people have died making this mistake.
Altitude illness can be fatal. This is not a condition to brush off. The clinic sees multiple deaths from altitude illness every year.
Garlic soup will not save you. This popular trail remedy has no medical basis whatsoever. The only proven way to prevent altitude illness is to ascend slowly.
Rest days are not optional. Even if you feel strong, skipping a rest day is not recommended. Acclimatization takes time regardless of how your body feels in the moment.
Hydration matters, but has limits. Drinking water will not prevent altitude illness, but dehydration can produce symptoms that closely mimic it. Staying hydrated remains essential.
Porters face serious risk. Local porters, often carrying heavy loads and ascending rapidly, are among the most vulnerable people on the mountain. Trekkers are encouraged to watch out for them and anyone else showing signs of illness, regardless of whether they are part of your group.
