Deep, abdominal breathing for 20 to 30 minutes each day will reduce anxiety and reduce stress, according to The American Institute of Stress (AIS). Deep breathing increases the supply of oxygen to your brain and stimulates the parasympathetic nervous system, which promotes a state of calmness.

Some research shows that deep breathing — and even sighing — brings relief to people with both low and high sensitivity to anxiety. While breathing has been shown to alleviate some anxiety, it is important to realize that panic attacks, anxiety disorders, and depression are mental health conditions.
