Can coffee worsen anxiety, and how can I recognise caffeine sensitivity?
Caffeine can worsen nervousness, palpitations and insomnia, with sensitivity varying between people. Symptoms can occur below 400 mg daily; that figure is neither a recommendation nor a suitable limit for everyone. Consider total intake, timing, medicines and health conditions.

Count different sources
Coffee, tea, energy drinks, supplements and some medicines may contain caffeine. Serving size and preparation change the amount, so cup counts can mislead. Pregnancy and certain health conditions require specific advice.
Make an observable change
Record intake, sleep, palpitations and anxiety. Reduce gradually after regular use; this may lessen withdrawal headache and fatigue without guaranteeing their absence. Try lower-caffeine options and avoid repeatedly using caffeine to compensate for lost sleep.
Do not blame every symptom on coffee
Persistent anxiety after reducing intake deserves assessment. Chest pain, fainting or severe breathlessness needs urgent care. Do not change prescribed treatment independently; ask a pharmacist about interactions.
