Coffee wakes you up in the morning and keeps you alert throughout the day, but how does its magic ingredient actually work?
The first thing to know is that part of your natural tiredness comes from a molecule called adenosine, which is produced by your body while it chugs along through the day. "While you sleep, the concentration of adenosine declines, gradually promoting wakefulness. Meanwhile, the more adenosine that builds up, the sleepier you feel.

Your morning coffee is able to hijack that process because caffeine looks a lot like adenosine to your brain cells:

Because of its similar shape, caffeine can bind to the adenosine receptors in your brain. Once the caffeine is locked into adenosine's rightful spot though, there is no way for the adenosine to stick around — which prevents it from building up and making you sleepy.

Without the molecule that usually induces exhaustion, "our natural stimulants run wild," Joseph Stromberg writes in Smithsonian. The result? You feel wide awake — at least for a while.

But all good things must come to an end, and your brain quickly wises up to your tricks.

When the adenosine is continually blocked from binding to its receptors, your body eventually creates more receptors — which means you need even more caffeine to plug them up. This can make kicking your coffee habit increasingly difficult, and make you need more and more caffeine to stay alert.

"When you try to quit drinking coffee or miss your daily intake, you might experience some withdrawal symptoms and feel more tired than you would have before you ever drank coffee."

But caffeine does more than just block adenosine. It can also pump up your levels of adrenaline and boost your mood — "the exact same thing cocaine does, just to a lesser degree,"

Good To Know... What of energy drinks

Energy drinks that contain caffeine do almost the same thing to our bodies,,, that's why it's advised you check a product carefully before you consume

ncoolboiy: Good Know... What of energy drinks

Caffeine is a naturally occurring chemical stimulant called trimethylxanthine. Its chemical formula is C8H10N4O2.
It is a drug, and actually shares a number of traits with more notorious drugs such as amphetamines, cocaine and heroin.
Caffeine uses the same biochemical mechanisms as these other drugs to stimulate brainfunction: If you feel like your mind is racing after drinking one too many energy drinks, you're not imagining things.
In its pure form, caffeine is a white crystalline powder that tastes very bitter. It is medically useful to stimulate the heartand also serves as a mild diuretic, increasing urine production to flush fluid out of the body.
Caffeine has been an integral part of global culture for hundreds of years. African folklore sets the discovery of coffee's energizing properties around 800 A.D., European and Asian accounts indicate that coffee and tea were local staples as early as the 1400s. Although coffee was often seen as a rare luxury for societies far removed from coffee-growing regions, foods and drinks made from other caffeine-containing plants were likely part of humankind's medical and nutritional arsenal since before recorded history.
Today, caffeine is used much as it has been for generations: It provides a "boost of energy" or a feeling of heightened alertness. Many former students can recall using strong coffee or caffeine pills to stay awake while cramming for finals. Likewise, drivers on long road tripsoften fill their cup holders with energy drinks or convenience-store coffees to help them push through to their destinations.
Remember, though, that caffeine shares some traits of those much harder drugs -- including the ability to cause addiction. Many people feel as though they cannot function in the morning without a cup of coffee (and its caffeine-powered boost) to kick-start the day. Caffeine's effects may be much milder than those of illicit drugs, but kicking a caffeine habit can be difficult for someone who has made the drug a large part of his or her diet and lifestyle.
Caffeine is unlike many other drugs in that it is abundant in what we eat and drink.
