Fear is one of the seven universal emotions experienced by everyone around the world. Fear arises with the threat of harm, either physical, emotional, or psychological, real or imagined. While traditionally considered a “negative” emotion, fear actually serves an important role in keeping us safe as it mobilizes us to cope with potential danger. What Is Fear? Fear is one of the most basic human emotions. It is programmed into the nervous system and works like an instinct. From the time we're infants, we are equipped with the survival instincts necessary to respond with fear when we sense danger or feel unsafe. Fear helps protect us.
