Why is Caffeine Bad for You?

Consuming too much caffeine can cause troubling side effects, including insomnia, anxiety, and kidney failure in extreme cases. On top of that, some people are considered caffeine sensitive. Caffeine-sensitive people can experience these side effects from a minuscule amount of caffeine.

Anxiety

Caffeine is lauded for its amazing ability to keep people awake and alert; this, however, can also be a problem. When too much caffeine is consumed, it goes from keeping you awake and alert to making you paranoid and anxious. Caffeine stops the production of adenosine, the drug that makes us tired. It also increases the production of adrenaline that activates our fight-or-flight reaction.

When you consume too much caffeine, you become overloaded with adrenaline and become anxious, jumpy, and paranoid.

Insomnia

As mentioned, caffeine blocks our brain from producing the drug that causes us to become tired. If you’re overloaded with adrenaline and your adenosine production is blocked, it will be impossible to get to sleep quickly. But that’s not the only way caffeine affects your sleep; an over-reliance on caffeine causes you to go to sleep later and wake up earlier.

Rhabdomyolysis

An overabundance of caffeine can also lead to rhabdomyolysis. Rhabdomyolysis causes skeletal muscles to break down and enter the bloodstream. This can eventually lead to kidney failure and death.

Caffeine Overdose

A caffeine overdose, like any other overdose, will result in death if you are not treated by professionals. The effects of a caffeine overdose include involuntary muscle movements, vomiting, hallucinations, confusion, chest pains, and irregular heartbeat. If you suffer from any of these symptoms and believe you’re having a caffeine overdose, you should call 911 immediately.
