What happens when you climb mount Everest with out no oxygen?

Answer 1

Climbing Mount Everest without supplemental oxygen significantly increases the risk of severe altitude sickness, as the air at high altitudes contains much less oxygen. At extreme altitudes, such as the summit of Everest, the body struggles to function due to hypoxia, which can lead to confusion, loss of coordination, and potentially life-threatening conditions like High Altitude Pulmonary Edema (HAPE) or High Altitude Cerebral Edema (HACE). Most climbers who attempt this extreme challenge are highly acclimatized and well-prepared, but even they face immense physical and mental challenges without oxygen support. Many climbers have died attempting the summit without supplemental oxygen, underscoring the dangers involved.
