It’s necessary to make sure when doing freestyle strokes, that a relaxed and natural diaphragmatic breath is taken first, with the first breath being relaxed and not hyperventilating or drawn from the upper chest. Instead, focus on taking a deep breath for three to five seconds and exhaling for the same time, using the diaphragm. The diaphragm can effectively aid in reducing heart rate and hyperventilation in general. It could take some time and several sessions for users with water phobia to become confident with this breathing method.
