What is Anxiety?
Anxiety is a natural response that everyone experiences at some point, particularly in stressful situations. Whether it’s a big presentation at work, an exam, or a first date, feeling anxious is completely normal. However, when anxiety becomes overwhelming, disproportionate to the trigger or situation (or age of the patient) and interferes with daily life, it falls into the category of anxiety disorders. Understanding anxiety is crucial for mental well-being. By recognizing what anxiety is, we can better address it and seek help when needed.
The Science of Anxiety
Anxiety impacts both the brain and body, triggering a complex series of reactions. When we sense danger, our brain activates the amygdala, which is responsible for our fight-or-flight response. This process releases stress hormones into our system, preparing us to react quickly.
Key neurotransmitters like serotonin and dopamine play significant roles in how we feel. When their balance is disrupted, it can lead to increased anxiety. For instance:
- Serotonin helps regulate mood and emotion.
- Dopamine is linked to motivation and pleasure.
Understanding these biological mechanisms can demystify anxiety and show how physical changes can affect mental states.
Common Types of Anxiety Disorders
While everyday anxiety is part of life, anxiety disorders are more severe and persistent. Here are some of the most common types:
- Generalised Anxiety Disorder (GAD): Characterised by excessive worry about various aspects of life, often without a clear cause.
- Social Anxiety Disorder: Involves intense fear and avoidance of social situations.
- Panic Disorder: Features sudden and repeated panic attacks, often with physical symptoms like heart palpitations.
- Specific Phobias: Terrifying fears related to particular objects or situations, such as heights or spiders.
- Obsessive-Compulsive Disorder (OCD): Involves unwanted, recurring thoughts (obsessions) and behaviors (compulsions) performed to alleviate anxiety.
- Post-Traumatic Stress Disorder (PTSD): Occurs after experiencing or witnessing a traumatic event, leading to flashbacks and severe anxiety.
NB the inclusion of OCD and PTSD is to match the ABS study on Anxiety, for which the results are as follows:
How Common Are Anxiety Disorders?
From Australian Bureau of Statistics. (2020-2022). National Study of Mental Health and Wellbeing. ABS. https://www.abs.gov.au/statistics/health/mental-health/national-study-mental-health-and-wellbeing/latest-release.
In 2020–2022, more than one in six Australians (17.2% or 3.4 million people) aged 16–85 years had a 12-month Anxiety disorder:
Females were more likely than males to have had a 12-month Anxiety disorder (21.1% compared with 13.3%)
Almost one in three people (31.8%) aged 16–24 years had a 12-month Anxiety disorder
Two in five females (40.4%) aged 16–24 years had a 12-month Anxiety disorder
One in two people (50.3%) who described their sexual orientation as Gay or Lesbian, Bisexual or who used a different term had a 12-month Anxiety disorder
One in four people (25.6%) living in one parent family households with dependent children had a 12-month Anxiety disorder
Females experienced higher rates of Social Phobia (9.2% compared with 5.2%) and Post-Traumatic Stress Disorder (7.4% compared with 3.7%) than males.
In comparison, in any given year the estimated percent of U.S. adults with various anxiety disorders are:
- Specific Phobia: 8% – 12% (U.S.)
- Social Anxiety Disorder: 7% (U.S.)
- Panic Disorder: 2% – 3% (U.S.)
- Agoraphobia: 1-1.7% (adolescents and adults; worldwide)
- Generalised Anxiety Disorder: 0.9% (adolescents)’ 2.9% (adults)
- Separation Anxiety Disorder: 4% (children); 1.6% (adolescents); 0.9%-1.9% (adults)
- Selective mutism: 0.03-1.9% (U.S., Europe, Israel)
Women are more likely than men to experience anxiety disorders.

Recognising the Symptoms of Anxiety
Identifying anxiety symptoms is crucial for seeking help. They can be broken down into three categories:
Emotional Symptoms
- Excessive worry about daily activities.
- Irrational fear that disrupts daily life.
Physical Symptoms
- Rapid heartbeat or palpitations.
- Muscle tension leading to fatigue.
- Sweating and trembling.
Behavioural Symptoms
- Avoidance of places or situations.
- Increased restlessness or irritability.
Acknowledging these symptoms can be the first step towards effective management.
Strategies for Managing Anxiety
If you’re feeling overwhelmed, stressed or restless, there are several effective strategies for managing anxiety, which can be grouped into lifestyle changes, mindfulness techniques, therapeutic interventions, and medical treatment.
Lifestyle Changes
- Regular Exercise: Physical activity releases endorphins, improving mood.
- Healthy Eating Habits: A balanced diet supports overall brain health.
- Adequate Sleep: Quality sleep can significantly reduce anxiety levels.
Mindfulness and Relaxation Techniques
- Meditation: Calms the mind and promotes a sense of peace.
- Deep Breathing Exercises: Helps regulate panic responses during stressful moments.
- Progressive Muscle Relaxation: Reduces physical tension and promotes relaxation.
Therapeutic Interventions
- Cognitive-Behavioural Therapy (CBT): Effective in changing negative thought patterns.
- Exposure Therapy: Gradually exposes individuals to feared situations in a controlled manner.
- Dialectical Behaviour Therapy (DBT): Combines CBT with mindfulness strategies to manage emotional reactions.
Medical Treatment for Anxiety Disorder
- Medications (like SSRIs and benzodiazepines): Should only be used under professional guidance.
- Innovative Approaches: repetitive Transcranial Magnetic Stimulation (rTMS) may be an option for some individuals.
When to Seek Professional Help for Anxiety Disorder
It’s important to recognise when anxiety starts to interfere with daily life, such as:
“If you find yourself unable to perform daily tasks or if anxiety becomes persistent and overwhelming, it might be time to seek help.”
