Can you tell if someone is lying by the temperature of their hands?

There is a common belief that a person's hands get colder when they lie, and that you can use this to detect when someone is being dishonest. However, this is actually a myth and not supported by scientific evidence.

While it is true that stress can cause changes in body temperature, it is not a reliable indicator of deception. The body's response to stress is complex, and can vary greatly from person to person. In fact, some people may experience the opposite effect, with their hands getting warmer when they are anxious or stressed.

There are many other factors that can affect body temperature, such as the environment, physical activity, and illness, making it difficult to use temperature as a reliable indicator of deception.

Instead, there are many other signs of deception that are more reliable, such as changes in vocal pitch and body language. Professionals, such as law enforcement officials and psychologists, are trained to look for these signs and use them to detect lies.
