Dr. Carl Peterson made a study, but he is tainted with scandal and came from ORU, so I gave a bad example for most here, though the study has been duplicated with the same results. In essence, the part of the brain that controls speech is almost shut down, and another part is highly active only while praying tongues. It also releases two chemicals that greatly enhance the immune system. Google it and choose your author. All I can really say is that it works in my walk.
