Which of the following is NOT an effect of Tesla high-frequency current?

1. Improves germicidal action

2. Stimulates blood circulation

3. Reduces body temperature

4. Relieves congestion

The correct answer is: Reduces body temperature

The choice identifying the action that is not an effect of Tesla high-frequency current is correct because Tesla high-frequency current is known primarily for its stimulating effects rather than for reducing body temperature. This type of current is often utilized in esthetic treatments for its various beneficial properties, including improving germicidal action, stimulating blood circulation, and relieving congestion. When applied to the skin, high-frequency current increases metabolic and blood circulation, thus enhancing oxygenation and nutrient delivery to the cells, which is beneficial for healing and rejuvenation. It also has a germicidal effect due to its ability to generate ozone and increase the temperature of the tissue, which can help reduce bacterial presence. However, the current does not serve to reduce body temperature; rather, it typically has a warming effect on the tissues. Thus, the notion of reducing body temperature contradicts the known properties of Tesla high-frequency treatments.
