Nervioso, or anxious, refers to a state of unease or worry that can affect individuals in various situations. It often manifests as a feeling of tension, apprehension, or fear about future events. Common triggers include public speaking, exams, or social interactions, where individuals may feel uncertain about their performance or acceptance. Physiologically, anxiety can lead to symptoms such as increased heart rate, sweating, or restlessness. It is a normal response to stress, but when it becomes excessive or chronic, it may require attention. Understanding and managing anxiety can involve techniques like mindfulness, breathing exercises, or seeking support from mental health professionals.
