Scuba divers are not the only athletes who can suffer the detrimental effects of sudden changes in pressure. Mountain climbers, too, are susceptible to the dangers of rapid ascent. At high elevation, air pressure is significantly lower than at sea level. A lower total pressure means a lower partial pressure of oxygen, and insufficient oxygen or hypoxia can cause altitude sickness. Early symptoms of altitude sickness include headache, dizziness. and nausea. In severe cases, climbers may suffer hallucinations, seizure, coma, and even death.
