Why do you get jittery when you drink to much coffee?



  1. 0 Votes

    Coffee contains Caffeine, which is a stimulant. As a stimulant, it can sometimes cause nerves to twitch, or jitter.

    Oddly, years ago, coffee was being prescribed to hyperactive children. Apparently, the caffeine would flood the brain receptors, causing something like a traffic jam, allowing the mind to concentrate better.

    It’s the caffeine. Along with nicotine and alcohol, caffeine is one of the three most mood-altering drugs in the world. Consuming one or more caffeine-rich beverages, such as coffee, will lead to situations some describe as ‘jitteriness.’ While caffeine does affect individuals differently many people experience a restless feeling due to how the caffeine stimulates their nervous system, heart, muscles, and centers controlling blood pressure.

    So why does it make us jittery? Well, as you may guess, it all starts in the brain. Adenosine is a simple base of sugars created in the brain that binds to adenosine receptors. This binding causes drowsiness by slowing down nerve cell activity. To a nerve cell, caffeine appears to be adenosine. After the sneaky caffeine binds with the receptors the nerves begin to speed up rather than slow down and prepare for sleep. So now, with increased neuron activity in your brain your pituitary gland panics and begins releasing adrenaline, the fight or flight hormone. This causes your body to undergo many changes very quickly, your heartbeat quickens, blood pressure rises, and muscles tighten all resulting in a feeling that most describe as jitteriness.

    Because caffeine content in coffee is so high, if you drink too much or too often, it can cause you to jitter. It is a stimulant and it can develop into an addiction. Just as you may jitter while you’re drinking it, you can develop a jitter when you’re even off it.
