The evidence is convergent. Multiple independent sources reach the same conclusion, the underlying mechanism is well-characterized, and even the field's most cautious voices treat it as worth doing.

Would love a "what would change this verdict" RSS feed. Sign me up if it exists.
So, um, well, cycles with it. Norepinephrine and dopamine cycle with the breathing cycle.
you changing doing hyperventilation and things that can cause a slight hypoxia have been shown to affect epinephrine release also norepinephrine so independent of the SAA they are also affecting neurotransmitters and also hormones
