Diaphragmatic breathing is an exercise technique to help strengthen your diaphragm and fill your lungs with air more efficiently. It can assist with projecting our voice louder while reducing vocal strain. For individuals with stroke experiencing dysarthria, it may be useful for addressing impaired respiratory strength and coordination. Diaphragmatic breathing has been shown effective to improve the exercise capacity and respiratory rate for people with chronic obstructive pulmonary disease (COPD). It can also benefit individuals with asthma. Because of the way it triggers our parasympathetic nervous system (rest and digest), it also promotes stress reduction and may reduce gastrointestinal symptoms. Reference: Hamasaki H.
