Shyness and introversion are different from each other. Shyness is an emotion, while introversion is a personality type. In social situations, particularly around strangers, shy people may feel uncomfortable, nervous, awkward, or have aversive physical reactions such as sweaty palms, elevated heart rate, or a stomachache. These aversive emotions and reactions that they feel when they attend parties or other social activities may push them away from social events. Introverts also tend to avoid social events, but they choose to do so because they feel more comfortable and energized being alone or with a few friends.
