Climbing Kilimanjaro, the Andes, or the Himalayas may bring excitement and energy, but experts warn of a hidden danger: altitude sickness. Rapid ascents can trigger serious health problems. Dr. Thomas Jelinek, scientific director of the Center for Travel Medicine in Germany, says the risk rises sharply at around 2,500 meters.
Symptoms include headaches, nausea, fatigue, and dizziness. Data show that about 21% of climbers in Nepal experience altitude sickness, while between 45% and 75% are affected on Kilimanjaro.
Jelinek explained that altitude sickness is serious but preventable, caused by reduced oxygen levels in the air.
At 5,000 meters, oxygen levels are roughly half of those at sea level. The most effective prevention is careful planning, medical consultation before travel, and attention to ascent routes. Jelinek also recommends training at high altitudes while sleeping at lower elevations – in other words, “climb high, sleep low.”
