Been meaning to post this for some time but keep forgetting...
On a trip to Orizaba, I was talking with an EMT in the hut. He said people need to be careful around stoves in enclosed places the night before a climb because the carbon monoxide that’s produced attaches to red blood cells, interfering with oxygen transport for 24 hours or longer.
Question 1—anyone else heard this from a reputable source?
Question 2—would this warning also apply to campfires?
(If you’re like me, you probably are near one or the other before most mountain trips.)
