What are the 5 physiologic indications that a human is lying?

Five physiological indications that a person may be lying include increased heart rate, elevated blood pressure, sweating (particularly in the palms), changes in breathing patterns, and pupil dilation. These physiological responses are often triggered by stress or anxiety associated with deception. However, it's important to note that these signs are not definitive proof of lying, as they can also be caused by other factors such as nervousness or discomfort.
