Different Types of Cupping Therapy and Their Unique Benefits ... Water cupping therapy, often utilizing warm water, is a specialized, natural cupping technique used primarily to increase local blood circulation, relax muscles, and treat conditions like nocturnal leg cramps. A glass or bamboo cup is filled one-third with warm water then quickly applied to the skin to create suction. Key Aspects of Water Cupping Therapy: Method: A practitioner fills a cup with warm water, creating a rapid, warm vacuum on the skin. Purpose: Primarily used for relieving muscle tension, improving blood flow, and reducing nocturnal leg cramps (NLC). Application: The cups are typically left in place for up to 10 minutes. Benefits: Similar to traditional cupping, it is believed to help "draw out" stagnant energy, reduce pain, and boost local circulation.
