Breathing patterns can predict focus levels and the ease of falling into or exiting sleep.

“However, as the work from Dr. Feldman and colleagues tells us, breathing is also fundamental to organ health and function at an enormous number of other levels. In fact, how we breathe, including how often we breathe, the depth of our breathing and the ratio of inhales to exhales actually predicts how focused we are, how easily we get into sleep, how easily we can exit from sleep.”
