When we begin to lie, our heart beats faster and breath shortens. At the same time, our mouths turn dry which, combined with the rapid breathing, can cause troubles with speaking.
When a person begins to lie, he turns his glance in another direction. It may be down but also sideways or upwards - just in a different direction. Liars often start looking to the door. They may also begin to stare at us in an effort to exhibit more confidence.
When someone starts playing with things at hand or, for example, with his clothes or hair, it indicates nervousness. Another signals include shuffling feet or tapping fingers. Again, these are signals of a subconscious effort of the body to escape.
