If you touch a pot that came off the stove and it is hot, your body sends to the brain so that your hand will move

away from the hot surface in order to protect itself from further injury. This automatic response is known as a reflex action, which is a rapid, involuntary response to a stimulus that helps to protect the body from harm. In the case of touching a hot surface, the reflex action helps to prevent burns and damage to the skin by quickly moving the hand away from the source of heat.
