New psychological discovery: The tip of your nose gets hot when you tell a lie

If you have read the fairy tale "Pinocchio", then you will know that Pinocchio is a child who loves to lie, so his nose keeps getting longer, but this is just a fairy tale used to educate children not to lie. But if you lie, your nose will indeed change.

Recently, a study found that when people lie, there is indeed a phenomenon similar to the "Pinocchio effect", but the nose does not become longer like in fairy tales, but the tip of the nose becomes hotter.

Through experiments, researchers have discovered that the temperature of certain specific areas of the human body changes with changes in emotions. The researchers discovered the effect after using thermal imaging to test the temperature of volunteers' nose tips. The volunteers themselves could also feel an increase in temperature at the tip of their nose. This temperature rise is caused by the anxiety caused by lying. When the volunteers tried their best to convince themselves that they were not lying, the tips of their noses cooled.

The study further found that when people lie, the insular cortex of the brain, which regulates body temperature, is activated, which is the main mechanism for the increase in temperature at the tip of the nose. In addition to the tip of the nose, the temperature of the orbital muscles at the inner corners of the eyes will also rise or fall with changes in a person's emotions.
