Anxiety is a common mental health condition caused by chronic stress, trauma, lifestyle habits, and chemical imbalances in the brain. It affects brain regions like the amygdala, hippocampus, and prefrontal cortex, leading to fear, poor focus, sleep problems, and emotional instability. Managing anxiety requires a holistic approach including healthy sleep, exercise, nutrition, mindfulness, herbal remedies, and professional therapy. With the right habits and support, anxiety can be controlled and long-term mental wellness can be achieved.
