It is often reported that tea and coffee are able to trigger anxious symptoms in certain people. However, this anecdotal evidence is not supported by studies that have investigated the effects of caffeine, coffee and tea on the symptoms of anxiety. For example in one study, researchers used a detailed examination of a large scale nutritional study that was performed on thousands of individuals. From this they reported that there was no association between the consumption of tea and coffee with symptoms of anxiety. In fact other studies have reported that tea may be beneficial at protecting from the development of anxiety and coffee may be beneficial at protecting from the development of depression. One possibility is that caffeine itself is not the cause of anxiety, but that withdrawal of caffeine leads to brain changes that worsen any already anxious feelings. General advice is that in sensitive individuals who feel that caffeine worsens any symptoms of anxiety, moderation or cessation is likely the best solution.
