What does increased perspiration indicate during an interrogation?

Increased perspiration during an interrogation typically signifies potential deception. This physiological response can be linked to the body's stress reaction, which may occur when an individual feels anxious or guilty about the information they are providing. When someone is being untruthful, they might experience heightened levels of stress, which can manifest as excessive sweating.

This bodily response serves as a potential indicator that the person may not be entirely honest. While it's important to consider that perspiration alone is not a definitive sign of deception, in the context of an interrogation, it can be one of several cues that suggest the individual may be hiding something or not being forthcoming with the truth. Understanding these physiological signs can aid an officer in assessing the credibility of the statements made during an interrogation and determining the appropriate follow-up questions or strategies.
