The LA Times recently posted an article about altitude and said the following:
QUOTE Anyone who has climbed Half Dome or played baseball in Colorado knows that high elevation causes shortness of breath and other symptoms of “hypobaric hypoxia,” due to low pressure and oxygen Good article, but having hiked Yosemite’s Half Dome 38 times and written the only guide book on it, I disagree that being at the top of Half Dome rebated to your statement that it’s “high elevation causes shortness of breath and other symptoms of “hypobaric hypoxia,” due to low pressure and oxygen. UNQUOTE
What do YOU think about this?
I’m no expert or Nobel prize winner….but I think neither is the author. My take: Half Dome is only 8,842 feet high – not enough to cause those symptoms. Aircraft are pressurized to 8,000 feet. Tuolumne Meadows to the north of the Valley is also at about 8,000 feet. People don’t keel over hypobaric hypoxia. While I agree that each person is different and altitude sickness is individualized and people can react differently, you need to be much higher – say 11,000 ft and higher to experience “hypobaric hypoxia.” Even then you may get the classic “altitude sickness” symptoms – headache and nausea and diarrhea. Ask my brother. He got these at 12,000′ as we went up Mt Whitney. I felt fine the whole time.
Toss your 2 cents in and let’s hear your opinion and/or experience.
