Hi, we typically breathe in and out through the nose all the time, when relaxed. We sometimes exhale through the mouth if manifesting power, such as yelling 'Ha!'.
People practicing internal arts, qigong, meditation should use this breathing if possible/comfortable, because there is a risk when exhaling heavily through the mouth, of stimulating the vagus nerve, which stimulates your sympathetic nervous system resulting in elevated stress hormones in the bloodstream! not the effect we're looking for.
Hope this helps.
