What Is Anxiety?
Normal Anxiety vs Anxiety Disorders
Anxiety is a natural response to stress or danger—the body’s “fight or flight” system preparing us to respond to threats. However, when anxiety becomes:
- Excessive given the situation
- Persistent over months
- Interfering with daily activities
- Causing significant distress
…it may indicate an anxiety disorder requiring professional support.

- Shortness of breath or hyperventilation
- Dizziness or lightheadedness
- Nausea or stomach problems
- Muscle tension
- Fatigue
- Sleep disturbances

Evidence-Based Treatment Options
Effective Treatments Exist
Anxiety disorders are highly treatable. The right treatment can significantly reduce or eliminate symptoms.
Cognitive Behavioural Therapy (CBT)
CBT is the gold-standard treatment for anxiety disorders:
- How it works: Identifies and challenges anxious thoughts; changes behaviour patterns
- Effectiveness: 60-80% of people experience significant improvement
- Duration: Typically 6-20 sessions
- Techniques: Cognitive restructuring, exposure therapy, behavioural experiments
Medication
Several types of medication can help:
- SSRIs (Selective Serotonin Reuptake Inhibitors): First-line medication for anxiety
- SNRIs (Serotonin-Norepinephrine Reuptake Inhibitors): Alternative to SSRIs
- Benzodiazepines: Short-term use only (risk of dependence)
- Beta-blockers: For physical symptoms (e.g., propranolol for performance anxiety)
Self-Help Strategies
Complementary approaches:
- Regular exercise: Reduces anxiety symptoms
- Relaxation techniques: Deep breathing, progressive muscle relaxation
- Mindfulness and meditation: Apps like Headspace or Calm
- Limiting caffeine and alcohol: Both can worsen anxiety
- Good sleep hygiene: Anxiety and sleep problems often co-occur
When to Seek Professional Help
Consider seeking help if anxiety:
- Persists for more than a few weeks
- Interferes with work, relationships, or daily activities
- Causes significant distress
- Leads to avoidance of important activities
