Which of the following is a common outcome of improper cupping techniques?

Improper cupping techniques can lead to skin infections, as the cups create suction on the skin which can break the skin’s barrier if not applied correctly. This disruption can introduce bacteria and other pathogens, resulting in infections. The risk of infection increases if the cups are not sanitized properly before use or if the skin is not adequately prepared.

In contrast, enhanced energy levels, improved sleep quality, and decreased pain sensitivity are considered potential benefits of cupping therapy when it is performed correctly. However, these outcomes are not typically associated with improper techniques and do not occur in the same way or to the same degree if proper hygiene and technique are neglected. Therefore, the likelihood of skin infections stands out as a direct and negative consequence of poorly executed cupping practices.
