“Caffeine is a stimulant, which may worsen anxiety in some individuals,” says McGrane. “If you regularly experience anxiety or panic attacks, you may want to consider avoiding or reducing your caffeinated coffee intake.”Research from General Hospital Psychiatry found that higher levels of caffeine (around 5 cups of coffee per day) could potentially bring on panic attacks in those with existing anxiety. Even if you’re not consuming 5 cups, you can still watch your intake to ensure that you’re not worsening any existing anxiety in your daily life.
