Understanding Anxiety
Feeling anxious from time to time is a normal part of life. Many people experience nervousness before an important meeting, exam, interview, or major life event. In most cases, these feelings are temporary and disappear once the stressful situation has passed.
However, anxiety becomes a health concern when feelings of fear, worry, or nervousness become frequent, overwhelming, or begin to interfere with everyday activities. Anxiety disorders are among the most common mental health conditions worldwide, affecting millions of people each year.
Learning about anxiety can help you recognise the signs early, understand available treatment options, and know when to seek professional advice.
What Is Anxiety?
Anxiety is the body’s natural response to stress or perceived danger. It activates the “fight, flight, or freeze” response, preparing the body to react to challenging situations.
While occasional anxiety is normal, an anxiety disorder involves excessive or persistent worry that is difficult to control and continues even when there is little or no immediate threat.
Anxiety disorders can affect people of all ages and backgrounds and vary in severity from mild to severe.
Common Symptoms of Anxiety
Symptoms can differ from person to person and may include both physical and emotional effects.
Emotional Symptoms
- Persistent worry or fear
- Feeling overwhelmed
- Difficulty concentrating
- Restlessness
- Irritability
- Feeling constantly “on edge”
- Fear that something bad will happen
Physical Symptoms
Anxiety often produces physical symptoms because the body’s stress response affects multiple systems.
Common physical symptoms include:
- Rapid heartbeat
- Sweating
- Trembling
- Muscle tension
- Shortness of breath
- Dizziness
- Dry mouth
- Upset stomach
- Nausea
- Fatigue
- Difficulty sleeping
Some people experience panic attacks, which involve sudden episodes of intense fear accompanied by symptoms such as chest tightness, rapid breathing, and a racing heart. These symptoms can feel frightening and may resemble other medical conditions, making professional assessment important when they occur for the first time.
Types of Anxiety Disorders
Healthcare professionals recognise several different anxiety disorders.
Generalised Anxiety Disorder (GAD)
People with GAD experience excessive worry about everyday situations, including work, health, finances, and family life.
Panic Disorder
Characterised by recurring panic attacks that occur unexpectedly.
Social Anxiety Disorder
Involves intense fear of social situations where a person worries about embarrassment or being judged by others.
Specific Phobias
Extreme fear of particular objects or situations, such as flying, heights, injections, or spiders.
Separation Anxiety Disorder
Although commonly associated with children, adults may also experience excessive anxiety related to separation from loved ones.
What Causes Anxiety?
There is rarely a single cause.
Instead, anxiety usually develops due to a combination of biological, psychological, and environmental factors.
These may include:
- Family history of anxiety disorders
- Stressful life events
- Financial difficulties
- Relationship problems
- Chronic illness
- Lack of sleep
- Traumatic experiences
- Workplace stress
- Certain medications
- Excessive caffeine consumption
- Alcohol or recreational drug use
Sometimes anxiety develops gradually without an obvious trigger.
Who Is More Likely to Experience Anxiety?
Although anyone can develop anxiety, certain factors may increase the likelihood.
These include:
- Previous mental health conditions
- Ongoing stress
- Chronic pain
- Serious illness
- Family history
- Major life changes

How Is Anxiety Diagnosed?
There is no single laboratory test for anxiety.
Healthcare professionals usually diagnose anxiety by discussing:
- Your symptoms
- How long they have been occurring
- Their impact on daily life
- Medical history
- Current medications
- Lifestyle factors
They may also assess whether another medical condition could be contributing to your symptoms.

Many people benefit from a combination of approaches.
Psychological Therapy
Talking therapies are commonly recommended.
Examples include:
- Cognitive Behavioural Therapy (CBT)

- Mindfulness-based therapies
These approaches help people understand thought patterns and develop healthier coping strategies.
Medication
In some cases, healthcare professionals may prescribe medication when anxiety is significantly affecting daily life.
Medication should always be used according to medical advice, with regular review to assess benefits and potential side effects.
Lifestyle Changes
Healthy lifestyle habits can make a meaningful difference.
Helpful strategies include:
Regular Exercise
Physical activity can improve mood and reduce stress.

Try to:
