5 Giveaways That You're Lying

Studies have shown that the average person tells two to six lies every day. And the numbers may be on the rise due to the less confrontational nature of e-mail and texting. But beware. While lying, some people may unintentionally give themselves away. Here are tip-offs that someone isn’t being straight with you.
That blinking feeling
Recent research reveals that certain patterns of blinking could be tied to lying. Some studies show that we blink less when we are lying because attention is focused when creating an intricate lie. Additional studies have shown that someone telling a lie will blink more frequently than a truth-teller seconds after telling a lie, likely as a release of energy after the intense concentration of lying.
The nose knows
Despite the familiar fairy tale, noses don’t grow with each lie, but we do experience a different nasal phenomenon–an increase in nose temperature. Researchers at the University of Granada found that when we lie, especially about our feelings, the temperature around our nose raises and the insula region of the brain, which is associated with its reward system, is activated.
The lying cold
A new study has found that cutting back on lying can actually boost your mental and physical health. Truthful participants reported feeling significantly more relaxed, happier and had fewer sore throats and headaches than the lying group. This is because lying increases levels of anxiety which is attributed to inflammation, which leads to symptoms such as headaches and sore throats.
New technology has sparked a debate as to whether brain scans are more accurate than conventional lie detectors. When people lie, they use different parts of their brain from those that are used when they tell the truth, and such brain activity can be measured by functional magnetic resonance imaging (fMRI). Studies have shown that the fMRI was equally as accurate at identifying lies as the polygraph exam.
The heart doesn't lie
This one is fairly obvious and can be serious. The anxiety associated with lying can cause a sharp spike in heart rate and blood pressure. This is why a polygraph test measures pulse. Researchers warn that like chronic worriers, chronic liars could be at an increased risk of developing diseases associated with chronic stress including cancer, diabetes and heart disease.
