On which part of the thumb is Shiatsu typically performed?

Shiatsu is a form of Japanese massage that emphasizes the application of pressure to specific points on the body, often referred to as acupressure points. The technique utilizes various parts of the hands, and in the case of the thumb, the digital ball is the most effective area for applying pressure.

The digital ball of the thumb is the fleshy pad located at the tip of the thumb, which is particularly well-suited for performing Shiatsu techniques. This area is adept for creating firm pressure and is sensitive enough to interact effectively with the body's energy pathways, or meridians, which Shiatsu aims to balance.

Using the ball of the thumb allows the practitioner to apply pressure in a concentrated manner, which is essential for stimulating these points effectively. This technique facilitates deeper contact, helping to alleviate tension, improve circulation, and promote relaxation in the recipient. Other parts of the thumb, such as the base, joint, or nail bed, may not provide the same level of control or effectiveness in Shiatsu practice.
