Deep breathing techniques refer to a set of practices that involve taking slow, deep breaths in order to calm oneself and reduce stress. These techniques are often used as part of relaxation or meditation exercises, with the goal of promoting mental clarity, reducing anxiety, and improving overall well-being. Deep breathing can be done through various methods such as diaphragmatic breathing, slow belly breathing, or box breathing, among others. The idea is to focus on your breath, taking long, slow inhales and exhales, which helps activate the body's relaxation response and promote a sense of calmness.
