Breathing techniques refer to various methods or practices that help a person regulate their breath, either by altering its pace, depth, or rhythm. These techniques are often used as part of relaxation and stress reduction exercises, meditation practices, and in some cases for physical fitness training. The goal is usually to achieve a state of calmness, focus, or mental clarity through the conscious control of breathing. Some common examples include deep breathing exercises, slow and controlled breaths, and rhythmic breathing patterns such as those used in yoga or Pilates.
