If you are having trouble reining in your nerves, maybe lay off that third or fourth shot of espresso. As explained by Healthline, caffeine "works by blocking the effects of adenosine, a brain chemical that makes you feel tired" and inciting "the release of adrenaline, the 'fight or flight' hormone associated with increased energy." While this is what helps us get that much-desired energy boost in the morning, when consumed in excess, these otherwise desirable effects can cause anxiety.
Those who take in 1,000 milligrams or more of caffeine per day may find themselves experiencing jitters and other symptoms of extreme nervousness. In fact, the Diagnostic and Statistical Manual of Mental Disorders, published by the American Psychiatric Association, lists caffeine-induced anxiety as one of four syndromes caused by caffeine, per Healthline.
So next time you are pacing the house, debating if you should pour another shot, take a deep breath — and consider a cup of decaf instead. Curious if you should curb your caffeine habit? Here are signs you're drinking too much caffeine.
