> Anyone with anxiety or sleep issues should reexamine their caffeine usage. They should. The relationship between caffeine and mood disorders like anxiety is incompletely understood. Caffeine may help some, particularly at lower doses [1]. However some studies find that the effect on anxiety is minimal or doesn’t occur [2]. Caffeine seems to improve psychological well-being at a minimum [3]. There may be a self-medication element between ADHD and caffeine too, though the data isn’t good [3]. The interactions with medications is also complex and hard to control for due to the large number of caffeine users.
