What is the purpose of deep breathing?

Deep breathing lays the groundwork for good health. When you breathe deeply, you are less stressed, which prevents many illnesses. Plus, deep breathing promotes calmness, so you are less irritated and anxious, which also helps prevent chronic health conditions. I try to practice deep breathing techniques a few times each day, particularly in the morning and evenings.
