What Is Anxiety?

Anxiety is a natural emotional response to stress, uncertainty, or perceived danger. It’s something everyone experiences—like before a big presentation or job interview. However, when anxiety becomes excessive, persistent, and interferes with everyday life, it transitions from a normal emotion into a clinically recognised mental health disorder.

According to the World Health Organization (WHO), anxiety disorders involve excessive fear or worry that is difficult to control and significantly impairs social, occupational, or other important areas of functioning. The National Institute of Mental Health (NIMH) and American Psychiatric Association (APA) also classify anxiety as a mental health condition under the broader category of mood and affective disorders.

Everyday Anxiety vs. Anxiety Disorder

• Everyday Anxiety: Feeling nervous before a job interview or tight deadline.
  
• Anxiety Disorder: Intense, unrelenting worry about work performance even when there’s no reason, leading to physical symptoms and avoidance.

In short, clinical anxiety is diagnosable when it disrupts daily tasks, relationships, or work performance.

Clinical Definition by Medical Authorities

Health authorities globally agree:

• WHO defines anxiety disorders as excessive fear and related behavioural disturbances.
  
• APA includes anxiety disorders in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5).
  
• NIMH recognises anxiety as the most common mental illness, affecting over 30% of adults at some point in their lives.

Types of Anxiety Disorders

Anxiety doesn’t look the same for everyone. Different forms have distinct characteristics:

Generalised Anxiety Disorder (GAD)

GAD involves chronic worry about various aspects of life—work, health, relationships—often without a specific cause. Symptoms include fatigue, tension, and sleep problems.

Panic Disorder

This disorder features sudden, recurring panic attacks—intense episodes of fear with symptoms like chest pain, shortness of breath, or dizziness.

Social Anxiety Disorder

Characterised by fear of judgement or embarrassment in social or performance settings. It often leads to avoidance of work meetings, presentations, or even team lunches.

Specific Phobias

Irrational, intense fears tied to specific objects or situations—like flying, heights, or public speaking—can become disabling.

Agoraphobia

Involves fear of being in places where escape might be difficult, such as public transport or crowded spaces.

Separation Anxiety Disorder

Commonly associated with children, but also affects adults, especially when away from loved ones or safe environments.

Selective Mutism (in Adults)

A rare condition where individuals are unable to speak in certain social situations despite having the ability to do so.
