Significance of Negative pressure
Negative pressure is a concept that can arise in various contexts. In breathing, it refers to the state in the nasal cavity that enhances airflow and facilitates mucociliary clearance. In cupping therapy, negative pressure is generated to dilate local blood vessels and improve circulation. Additionally, during Jalaukavacharana, when a leech sucks blood, it induces negative pressure to promote venous drainage and alleviate local swelling. Overall, negative pressure is significant in improving both respiratory function and circulation.
