Stress is a natural response to challenging situations, often triggered by external factors like work pressure or personal issues. It activates the body's fight-or-flight response, releasing hormones such as cortisol and adrenaline. While some stress can be beneficial, chronic stress can lead to various health problems, including anxiety and depression. Emotions are complex reactions that involve physiological responses, thoughts, and behaviors. They can be influenced by stress, as heightened stress levels may intensify feelings like anger, fear, or sadness. Understanding the connection between stress and emotion is essential for managing mental health and improving overall well-being.
