# Anxiety
---
**Anxiety** is a vague, uneasy feeling of discomfort or dread, often without a clear source. It is the most common [[stress]] response in humans. Low levels of anxiety can be [[stress#Types of Stress|helpful]] as a motivation for survival, but high, prolonged levels are unhealthy.
Anxiety is distinct from fear, although they are similar in some respects. Fear is an appropriate and present-oriented and short-lived response to a clearly identifiable and specific threat. Anxiety is future-orientated, long-acting response that is broadly focused on a diffuse threat.
[[coping mechanism]] / [[cognitive behavioral therapy]]
Anxiety is classified in four levels, mile, moderate, severe and panic.
- **Mild anxiety** is present in day-to-day living. It can actually motivate learning and growth, though it can also affect sleep and interfere with problem solving skills.
- **Moderate anxiety** manifests as "butterflies in the stomach", with an increase in respirations and pulse. This level of anxiety begins to narrow a person's focus onto the immediate concern.
- **Severe anxiety** narrows a person's focus even more, with almost all attention being towards gaining relief. This is no longer a beneficial state that functions as a signal for danger, but is a maladaptive response that indicates an emotional disability or anxiety disorder. Signs and symptoms of severe anxiety are:
- difficulty communicating verbally
- increased motor activity
- a fearful facial expression
- [[headache]]
- [[nausea]]
- [[dizziness]]
- [[arrhythmia|tachycardia]]
- [[respiration rate|hyperventilation]]
- **Panic** is a state where someone has lost all control and are unable to think rationally. A person in panic experiences feelings of dread, terror or impending doom. They are unable to concentrate and have a distorted perception of events. Manifestations of panic are:
- difficulty communicating verbally
- agitation
- trembling
- poor motor control
- sensory changes
- sweating
- [[arrhythmia|tachycardia]]
- [[respiration rate|hyperventilation]]
- [[dyspnea]]
- [[arrhythmia|palpitations]]
- a choking sensation
- sensations of chest pain or pressure
