Could Coffee Be the Next Silent Killer? Know Why You Should Drink It Moderately

Fight or flight

One of the many reasons people drink coffee is to increase their alertness. This is possible because caffeine blocks the effects of adenosine, which is responsible for making you feel tired. The increased alertness comes from the caffeine triggering adrenaline to be released.

When adrenaline is released, you get increased energy. However, adrenaline is also known to be the fight or flight hormone. When high doses of adrenaline are released in your body, you can get very nervous or anxious.
