For some people, coffee can be of encouragement in the morning. Wake up in the morning without a sip of warm coffee, it definitely doesn't taste good. There are more people who rely on coffee when her spirits began to decline during the day. They believe, coffee can improve their passion in the day.
For the coffee addicts, drink black it can indeed make You feel energized.
Explanation natural is actually simple, the caffeine that is contained in a copy that injects that energy on yourself. The caffeine in coffee, has a structure similar to adenosine, a molecule found in the brain and is responsible for the fatigue that You feel. Adenosine will fill the receptors in the brain and lowers the activity of Your brain so it will fatigue.
The more adenosine that lodged in the brain, You will be more tired. But, when sleeping, the amount of adenosine in the brain decrease and make You wake up in the morning. It makes sense if the longer You are awake, You will be more tired.
When consuming coffee, the receptors in the brain that become breeding places of adenosine to produce fatigue, replaced with the molecules of caffeine blocking adenosine nesting on the brain. As a result, a sense of fatigue was lost because adenosine is not lodged in Your brain.
When this effect occurs in the long term, which means You consume coffee in the span of a long time, the brain will produce more receptors for caffeine. When You miss the ritual of drinking coffee that You would normally do, the receptors will be empty and returned filled with adenosine which makes You feel tired, weak, even not as excited as when You consume coffee.
This is what makes a person such as addiction to drink coffee.
However, the effect of coffee in the body is not limited to that only. Caffeine can increase the production of adrenaline, which can increase the heart rate and dilates blood vessels. Caffeine can also increase the production of dopamine which can cause feelings of happiness. It is also that make coffee making people dependence.
