Nervousness is a common emotional response characterized by feelings of anxiety, apprehension, or unease. It often occurs in situations that involve uncertainty or potential challenges, such as public speaking, taking exams, or meeting new people. Physical symptoms may include a racing heart, sweating, or trembling, which are part of the body's natural fight-or-flight response. This feeling can be triggered by various factors, including stress, fear of failure, or social situations. While some level of nervousness can be normal and even beneficial, excessive nervousness may interfere with daily activities and overall well-being, potentially leading to conditions like anxiety disorders.
