Digging the web for some deeper information on breathing physiology and metabolism, I found an interesting and almost funny (though completely serious) abstract of a document describing that hypoxemia can be used for treating pathologic depressions (including schizophrenic depressions):
PEP Web - Treatment of Depressions with Hypoxemia: Gurevitch, Sumyanskaya and Khachaturean. J. of Clinical Psychopathology, VI, 1945, pp. 523–535.
That may explain why freedivers are so nice and happy folks
