What Caffeine Does to Your Body and Brain

•One of the things rarely mentioned about caffeine is that it is, in fact, a drug.

•Caffeine is the most commonly used psychoactive drug in the world.

•It makes us feel alert, at least for a while.

“It’s normal to grow tired as the day progresses – our brains naturally produce more of a molecule called adenosine from the time we wake up until the time we go to sleep. Scientists think this helps us get to bed at night. Caffeine hijacks this natural process by mimicking adenosine in the brain. It latches onto the receptors designed for adenosine, pushing them out of the way. As a result, we’re left feeling more alert and awake. Eventually, however, adenosine wises up to caffeine’s act and makes new receptors for the sleep-inducing molecule to start latching onto again. This is why your morning cup of coffee can suddenly turn into two – the more receptors you have, the more caffeine you need to plug them up”.

•It boosts our mood.

“This is due to the same adenosine-blocking effect that makes you feel alert. By blocking adenosine’s relaxing effects, caffeine lets dopamine and glutamine (other natural stimulants produced by your brain) run wild, making you more alert, less bored, and providing a mood boost”.

•It improves our memory.

“Caffeine has been shown to improve certain types of memory – especially the ability to remember lists of words and straightforward information – in some (but not all) studies. Some research shows that it helps those memories “stick” in the brain as well, making it easier to recall that information later. This enhancement, however, seems to be strongest for people who aren’t already hooked on caffeine in the first place”.

•Decaf isn’t the same as caffeine free.

A 2007 Consumer Reports analysis looked at 36 cups of decaffeinated coffee and found that some contained more than 20 mg, reported.

•Caffeine starts working in just minutes.

According to the American Academy of Sleep Medicine, it takes about 30 to 60 minutes for caffeine to reach its peak level in the blood (one study found increased alertness can begin in as few as 10 minutes). The body typically eliminates half of the drug in three to five hours, and the remainder can linger for eight to 14 hours. Some people, particularly those who don’t regularly consume caffeine, are more sensitive to the effects than others.Sleep experts often recommend abstaining from caffeine at least eight hours before bedtime to avoid wakefulness at night.

•But it doesn’t affect everyone the same way.

The body might process caffeine differently based on gender, race and even birth control use. Women generally metabolize caffeine faster than men. Smokers process it twice as quickly as nonsmokers do. Women taking birth-control pills metabolize it at perhaps one-third the rate that women not on the Pill do. Asians may do so more slowly than people of other races.

•Energy drinks often don’t have more caffeine than coffee.

many popular brands actually contain considerably less than an old-fashioned cup of black coffee. An 8.4-ounce serving of Red Bull, for instance, has a relatively modest 76 to 80 mg of caffeine, compared to the 95 to 200 mg in a typical cup of coffee, the Mayo Clinic reports.

•Dark roast coffees actually have less caffeine than lighter roasts.

the truth is that light roasts actually pack more of a jolt than dark roasts. The process of roasting burns off caffeine.

•Caffeine can be found naturally in more than 60 plants.

It’s not just coffee beans: tea leaves, kola nuts (which flavor colas) and cocoa beans all contain caffeine. The stimulant is found naturally in the leaves, seeds and fruits of a wide variety of plants. It can also be manmade and added to products.


I hope that you found this post to be insightful and maybe even helpful. I gain quite a different perspective of Caffeine after researching for this post. I am now more aware of the Dangers and the great benefits that this compound brings. Please share this post if it has caught your attention in any way.
