High-altitude sickness is a dangerous condition that is often underestimated by mountaineers. Experts warn that rapid ascent can cause serious health problems. According to Thomas Gellinek, scientific director of the German Center for Travel Medicine, the risk of altitude sickness increases sharply at an altitude of about 2500 meters. Symptoms include headache, nausea, fatigue, and dizziness. Health experts note that symptoms usually subside within 1-3 days after descending by 500-1000 meters. In severe cases, the climber must descend immediately and, if possible, seek medical help. In the worst cases, altitude sickness can be life-threatening, causing fluid in the lungs or brain swelling. Experts also point out that certain medications like acetazolamide and dexamethasone can help prevent symptoms of altitude sickness. To prevent the illness, Gellinek advises carefully planning the climb, getting a medical consultation before traveling, and paying close attention to the ascent route. He also recommends training at high altitudes but sleeping at lower ones. Here are some tips for being in the mountains: you should rest for at least a day after every 1000 meters of ascent, start at 2500 meters, and the sleeping altitude should not increase by more than 300-600 meters per day. You should also drink enough fluids, as dehydration can worsen the symptoms of altitude sickness. If you experience symptoms like a headache or dizziness, which usually occur 6-12 hours after a rapid ascent to over 2000 meters, you must stop immediately.
