My daughter, who got her Masters in biology relatively recently, suggested that this appears to be the "expected" way that mammals purge stress. I was told during my meditation classes that, during slow breathing, the amplitude of various waves on an EEG change. Waves that are associated with sleeping/resting gaining amplitude, while those associated with stress decrease in amplitude. I know from my own experience that it works for me to calm down stage fright prior to public speaking or important presentations :-).
