Which breathing technique is considered to promote relaxation through equalizing inhalation and exhalation?

Nadi Shodhana is a breathing technique, also known as alternate nostril breathing, that promotes relaxation and balance within the body and mind. This practice involves inhaling through one nostril while closing the other and then exhaling through the opposite nostril. The emphasis on equalizing the duration of inhalation and exhalation helps to calm the nervous system and reduces stress, thereby fostering a state of relaxation.

This technique is particularly effective because it not only influences the breath but also engages the subtle energy channels (nadis) within the body, leading to a harmonized state both physically and mentally. By balancing the flow of breath and energy, Nadi Shodhana encourages a sense of tranquility and promotes deeper states of relaxation and mental clarity.

Other techniques, while beneficial in their own right, do not focus specifically on equalizing inhalation and exhalation to the same extent as Nadi Shodhana. Ujjayi involves a constricted throat and is energizing. Chandra Bhedi focuses on inhaling through the left nostril, creating a cooling effect, and Bhastrika is a vigorous technique designed to energize the body through rapid inhalation and exhalation.
