Understanding anxiety: what it is, what helps and when to seek support

Anxiety is the most common mental health experience — and one of the most treatable. Here is what the evidence shows.

Normal anxiety vs anxiety disorder

Anxiety is a normal, protective response to perceived threat. It becomes an anxiety disorder when it is disproportionate to the actual threat, persistent (not resolving when the trigger is removed), and interfering with daily functioning. Generalised Anxiety Disorder (GAD), panic disorder, social anxiety and phobias are all different expressions of the same underlying mechanism. Use our free mental health tracker to document the pattern before speaking to your GP.

What the evidence shows helps

Cognitive Behavioural Therapy (CBT) is the most extensively researched psychological treatment for anxiety, with strong evidence across disorder types. It typically takes 6–20 sessions. In the UK, it is available free on the NHS through IAPT (Improving Access to Psychological Therapies) — self-refer at nhs.uk/service-search/mental-health. Medication (typically SSRIs) is effective for moderate-to-severe anxiety and is often used alongside CBT. Exercise at 30+ minutes 3× per week has a measurable anxiolytic effect.

Self-management strategies with evidence

Diaphragmatic breathing (slow, deep breathing that activates the parasympathetic nervous system), scheduled worry time (contain rumination to a specific 20-minute period), exposure (gradually approaching avoided situations), and reducing safety behaviours (things done to prevent feared outcomes that maintain anxiety by preventing disconfirmation). Our free stress relief toolkit provides an immediate-response reference card.

Frequently asked questions

When should you seek professional help for anxiety?
When anxiety is affecting daily functioning for more than 2 weeks: work, relationships, sleep or physical health. You don't need to be in crisis to seek help. In the UK, you can self-refer to NHS Talking Therapies (IAPT) without going to a GP first — find your local service at nhs.uk. If anxiety is severe or involves suicidal thoughts, contact your GP urgently or call Samaritans (116 123, free, 24/7).
Does avoiding things make anxiety worse?
Yes, consistently. Avoidance provides short-term relief but maintains and strengthens anxiety long-term by preventing the nervous system from learning that the feared situation is actually manageable. This is why CBT-based exposure therapy (gradually approaching avoided situations) is the most effective treatment — it systematically disconfirms the threat signal.
