Why Mount Everest is so dangerous for humans #documentary #everest #mounteverest

you take your first step onto the trail to Everest. Just 3,000 meters above sea level. You feel strong. The air is thinner, sure, but you can breathe. And yet, this is where most people already start to lose. Muscles burn faster. Your brain slows down. You lose water with every breath, and you haven't even reached base camp. Keep climbing 5,364 meters. You're now higher than any mountain in Europe. The oxygen here? Only half of what your body's used to. You wake up with headaches. You stop sleeping well. And this is still the safe part. Now we go higher. 6,400 meters. Camp 2. Here the real danger begins. High altitude, pulmonary edema. Your lungs fill with fluid. You feel like you're drowning while you're still walking. You cough blood. You shake with cold, even when wrapped in heat. And still, climbers keep going. 7,200 meters. Camp 3. Your body starts eating itself. It can't recover. It doesn't want to. You're burning 6,000 calories a day, but eating barely half. 8,000 meters. The death zone. This is where your body starts dying. Slowly, quietly. No matter how strong you are, your cells begin to shut down. You lose control of your fingers. The oxygen here? Just 30% of sea level. Not enough to sustain life for long. Every second you spend here, your brain is starving, and your heart is racing itself to death. This is where climbers disappear. Like David Sharp, who sat down to rest in the death zone and never stood up again. Or Francis Arcenteev, the first American woman to reach Everest's summit without oxygen. She made it to the top, but didn't make it back down. So next time you see a photo of Everest, remember, you're looking at a place that slowly kills you the higher you go. Because up here, you don't conquer the mountain. It conquers you.
