Though coffee in moderate amounts is good for your brain, going overboard can kill the mood and even lead to deleterious effects. 'Too much caffeine, that's a different story. That leads to jitters, anxiety, and wrecked sleep, which leads to crankiness, brain fog, which is no good,' she shared. Caffeine can increase alertness by blocking the effects of adenosine, a brain chemical that makes you feel tired. This also triggers the fight-or-flight hormone adrenaline, which is linked with increased energy. But when you overdo coffee, the effects spike, leading to anxiety and nervousness. The American Psychiatric Association has listed caffeine-induced anxiety disorder as one of the four caffeine-related conditions recognized in the Diagnostic and Statistical Manual of Mental Disorders (DSM). A 2017 study has suggested that caffeine consumption is safe for vulnerable populations such as pregnant and lactating women, children, young adults, and people with underlying heart or other health conditions, such as mental illness, as it can impair cardiovascular function and sleep.
