Stress triggers the body’s “fight or flight” response, which is helpful in short bursts but harmful when it becomes chronic. Prolonged stress can disrupt sleep, weaken concentration, and lead to irritability or anxiety. Over time, it may contribute to depression, burnout, or physical symptoms like headaches, muscle tension, or low immunity. Managing stress early through relaxation techniques, healthy boundaries, and emotional support is essential. If stress begins affecting your daily functioning, seeking professional help can provide clarity and coping skills.
