Studies show that caffeine is a psychoactive stimulant that effects the central nervous system. In people who are sensitive to caffeine it can significantly promote anxiety and other related conditions and symptoms including sweaty palms, racing heart, panic attacks, insomnia and stress . If you tend to drink caffeine throughout the day and notice that you become anxious afterwards, we recommend that you consider cutting down on your caffeine intake. Try this for a week or two and see if you notice any changes in your symptoms. If you notice changes during that time you might want to consider permanently reducing your daily caffeine intake.
