A sour mood, often referred to as irritability, is a state of heightened sensitivity to stressors and frustrations. Individuals experiencing irritability may find themselves easily annoyed or upset by minor inconveniences. This emotional state can be triggered by various factors, including lack of sleep, stress, or underlying health issues. Irritability can affect daily life and relationships, leading to conflicts with family, friends, or coworkers. It is important to recognize the signs of irritability and address the underlying causes, which may involve lifestyle changes, stress management techniques, or seeking support from a mental health professional.
