Deep breathing techniques, such as diaphragmatic breathing, promote relaxation and help calm the nervous system. By focusing on slow, controlled breaths, individuals can reduce levels of stress hormones, decrease heart rate, and lower blood pressure. These techniques encourage a state of mindfulness, where one can become more aware of their thoughts and feelings, reducing anxiety and promoting a sense of well-being. Practicing deep breathing can also enhance oxygen flow in the body, which contributes to better physical and mental clarity.
