@Kyth'Py1k: maybe see if it adds more oxygen to the blood and brain, then see if more oxygen to the blood and brain increase mental performance...? Also, you need to define mental performance; i.e. staying calm in stressful situations vs. creativity levels...

@GregMcNulty Like I said before, by mental performance, I mean performance in any mental activity in any way.

*Emotional Intelligence 2.0* said that breathing deeply and slowly increases mental performance, but I couldn't find any studies that really study the claim, and the book is a self-help book, which tend to be extremely unrigorous. So, does it increase mental performance?
