Question 1

What keeps chronic anxiety going despite people wanting to overcome it?

Accepted Answer

The primary maintenance mechanism of chronic anxiety is avoidance — of situations, thoughts, feelings, and physical sensations associated with anxiety. Avoidance provides immediate relief but prevents the habituation and learning that would reduce anxiety over time. Safety behaviours (doing something to prevent feared outcomes — checking repeatedly, seeking reassurance, always having an exit route) similarly maintain anxiety by preventing disconfirmation of anxious beliefs. Worry itself can be a cognitive avoidance strategy — a form of mental "preparation" that feels productive but maintains hyperarousal.

Question 2

Can anxiety cause physical symptoms?

Accepted Answer

Yes — anxiety activates the sympathetic nervous system, producing real, measurable physical symptoms: racing heart, shortness of breath, chest tightness, muscle tension, headaches, gastrointestinal disturbance (nausea, diarrhoea, cramping), sweating, trembling, dizziness, and tingling. These physical symptoms are often the presenting complaint for people with anxiety who have not made the connection to psychological stress. Chronic anxiety also contributes to long-term physical health effects including elevated cardiovascular risk, impaired immunity, and increased vulnerability to pain conditions through persistent physiological activation.

Question 3

What is the role of nutrition in anxiety management?

Accepted Answer

Several nutritional factors directly influence anxiety neurochemistry. Magnesium (widely deficient in Western diets) modulates NMDA receptor activity and has consistent evidence for reducing anxiety. Omega-3 fatty acids reduce neuroinflammation relevant to anxiety. B vitamins support neurotransmitter synthesis. Blood sugar stability — impaired by high-sugar, high-refined-carbohydrate diets — directly affects anxiety levels through adrenaline responses to glucose drops. Gut microbiome health influences the gut-brain axis and serotonin production. Caffeine and alcohol both worsen anxiety despite their perceived calming (alcohol) and energising (caffeine) effects.

Question 4

What non-medication approaches have the best evidence for chronic anxiety?

Accepted Answer

CBT has the strongest evidence base across all anxiety disorders, consistently outperforming medication in long-term follow-up for many presentations. Acceptance and commitment therapy (ACT) has growing evidence, particularly for generalised anxiety. MBSR and mindfulness-based approaches reduce chronic anxiety through improving present-moment awareness and reducing experiential avoidance. Exercise — particularly aerobic — produces significant anxiolytic effects through multiple mechanisms. Breathing retraining corrects the chronic hyperventilation common in anxiety. These approaches produce more durable change than medication alone and are recommended as first-line interventions.
