Dangers of Caffeine

Caffeine can be a very dangerous substance; consuming too much or too much in one sitting can cause horrible side effects and even death. Some people are more caffeine sensitive than others and can experience the side effects with only a moderate amount of caffeine. So, if you experience any of these side effects, it’s time to consider cutting back.


Caffeine is lauded for its incredible ability to keep people awake, but what about when you don’t want to be awake? Caffeine has been shown to increase how long it takes you to get to sleep and reduce how long you stay asleep.


Caffeine blocks the production of adenosine, the chemical that makes us feel tired and triggers adrenaline, which makes us alert. Unfortunately, high levels of caffeine create too much adrenaline and block too much adenosine, making you feel jittery and nervous.


Rhabdomyolysis occurs when muscle fibers break down and enter the bloodstream, leading to kidney failure. To avoid this, it’s best to cap your caffeine intake to about 250 mg daily, especially if you’re not sure about your tolerance.


After the caffeine wears off, you will often find yourself more tired than you would be if you hadn’t consumed the caffeine at all. To avoid this, it’s best to limit your intake to a moderate amount.

Caffeine Overdose

Too much caffeine can lead to an overdose, which can be fatal. Serious signs of a caffeine overdose include vomiting, chest pain, confusion, hallucinations, trouble breathing, uncontrollable movement, convulsions, and irregular heartbeat. If you suffer from these, you should call 911 immediately.

You should call poison control if you experience less severe symptoms like dizziness, a fever, insomnia, diarrhea, and increased thirst.
