SHA is effective up to what depth (in cm)?

Explanation:
Depth of heating with superficial heat application is limited to tissues near the surface. This modality raises temperature mainly in skin and subcutaneous tissues, with practical effectiveness extending to about 3 cm. That’s why a depth of 3 cm is the best match: it reflects the typical reach of SHA in therapy. A depth of 1 cm would be too shallow to influence as much underlying tissue, while 5 cm or 10 cm would require deeper heating modalities and are not characteristic of SHA.
