6. Hand Rubbing or Face Touching
The stress of preparing to tell a lie can cause many physical symptoms. For example, the person’s extremities may start to feel cold or itchy as a result of the autonomic nervous system working to override their anxiety.
This often leads to hand rubbing, pulling on the ears or lips, licking or biting lips and even itchiness on the hands, ears and lips.
Keep an eye out for these telltale signs the next time you ask someone a question.
