What is abdominal breathing?

Diaphragmatic breathing or abdominal breathing is a method of breathing using your diaphragm in order to deepen your breathing. The diaphragm is an enormous muscle at the bottom of your lungs that is contracted and expanded when you breathe in and out. Abdominal breathing allows the breath to be deeper and improve the oxygenation of your blood and lessen stress. https://www.lunguk.org/
