Disc: Generally speaking, not spesific to the oxygen mask thing. > Some people believe it but experiments have shown that it makes no significant difference. It's a placebo effect. I cannot count the amount of times I heard this on medicines and treatments. A too high percentage of them turn out to be not plasebo after a short amount of time. I believe “the experiments shown <anecdatolly working and commonly practised treatment> is plasebo” is the the first line of defense of the medical status quo against change.
