Shaky Business: Caffeine Explained

Ever felt your hands shake or your heart race after a cup of coffee? That’s the infamous caffeine jitters at work. But why does it happen?

Caffeine is a powerful stimulant that blocks adenosine, a brain chemical responsible for making you feel relaxed and sleepy. While this keeps you alert, it also triggers the release of adrenaline, the "fight-or-flight" hormone. This surge can lead to increased heart rate, nervousness, and those telltale jitters.

Factors like your metabolism, sensitivity to caffeine, and even genetics play a role. Some people process caffeine quickly, while others feel its effects more intensely. Consuming caffeine on an empty stomach or in large doses can also amplify the jitters.

The good news? You can avoid the shakes by moderating your intake, staying hydrated, and opting for decaf or half-caf options—like those from Frequent Coffee! Balance is key to enjoying your brew without the buzz.
