Positives

• Some patients with long-running shortness of breath say diaphragmatic breathing can make breathing feel looser, calmer, or more restful when it finally clicks. Reddit.

Negatives

• It is not a universal fix: patients with a tight, stuck diaphragm or chest-wall restriction may still feel unable to breathe normally even when they try breathing exercises. Reddit.

Hurdles & Side Effects

• The practical challenge is matching the exercise to the problem, because neck tension, dysfunctional breathing, low CO2 tolerance, and muscle guarding can all make simple breathing drills feel too limited on their own. Reddit.
