Lecture Notes
1. Introduction to Stress and Anxiety
Definition of Stress:
- Stress is the body’s natural response to a challenge or demand. It can be caused by both good and bad experiences. When people feel stressed, their bodies react by releasing chemicals like adrenaline and cortisol, which prepare the body for action.
Definition of Anxiety:
- Anxiety is a feeling of worry, nervousness, or unease about something with an uncertain outcome. While stress is usually a response to a specific external cause, anxiety can be more generalized and persistent, even when there is no immediate threat.

3. Why Stress and Anxiety Happen
Stress:
- External Triggers:
- Schoolwork or exams
- Arguments with friends or family
- Major life changes (like moving or starting a new school)
- Biological Response:
- The “fight or flight” response is the body’s way of preparing to face a threat or flee from it. This response is triggered by the release of stress hormones, which cause the physical symptoms of stress.
Anxiety:
- Perception of Threat:
- Anxiety often occurs when we perceive a threat or danger, even if it’s not immediate. For example, worrying about what might happen in the future can cause anxiety.
- Brain’s Role:
- The brain’s amygdala plays a key role in processing emotions like fear and anxiety. When the amygdala senses a threat, it sends signals that can trigger anxiety, even if the threat isn’t real.
- Learned Behavior:
- Sometimes, anxiety is learned from past experiences. If a situation caused fear or worry before, the brain might trigger anxiety in similar situations in the future.
