Does Caffeine Cause Anxiety?
Caffeine doesn’t cause anxiety in everyone—but it can absolutely trigger or worsen it in some people. Because it stimulates the nervous system, it can intensify the very sensations that define anxiety. The key is awareness. If caffeine makes you feel energized and focused, it may be working for you. But if it leaves you feeling jittery, restless, or overwhelmed, it might be worth cutting back. Your ideal caffeine level isn’t a universal number—it’s the amount that lets you feel alert without tipping into anxiety.
