Why Coffee Keeps You Awake
Lets digress for a moment and look at what coffees most polarizing stimulant does to your central nervous system. Caffeine acts on a chemical in your brain called adenosine. According to neurologist Ajay Sampat, M.D., Adenosine is like a sleep-inducing molecule that your brain makes while youre awake. The longer youre awake, the more adenosine you have in your system.
He further explains that caffeine is essentially an adenosine antagonist, binding to molecules of adenosine and lessening its sleep-inducing effects.
Caffeine is so effective because it peaks right away and then lingers in your system for hours. Typically, the half-life of caffeine is around four to six hours, meaning that four to six hours after consumption, about half of that caffeine is still in your system.
One of the biggest knocks against coffee is the disruption it can have on healthy sleep cycles.
Caffeine can increase your arousal frequency how many times your brain wakes up each night, though you may not remember.
However, some studies have begun to debunk this claim.
Professionals from Harvard Medical School and Flordia Atlantic University studied 785 people for a total of 5,164 days and nights, arriving at the conclusion that beverages containing caffeine are less likely to cause sleep disturbances than most of us think.
It often depends on the individual. If you have had a cup of coffee every evening for twenty years, you may not have trouble sleeping.
It Might Enhance Memory Retention
While caffeines positive effect on alertness, attention, concentration, and mood is not such a surprise, its ability to enhance memory retention is based on a fairly new study. According to the journal Nature Neuroscience, Caffeine enhanced performance 24 hours after administrationWe conclude that caffeine enhanced consolidation of long-term memories in humans. It is important to note that more caffeine is not necessarily better nor will it always prove to have a positive impact on productivity. On the flip side, heres how quitting coffee affects your body.

Coffee Can Exacerbate Heartburn
When you drink coffee, you raise the level of acidity in your stomach. That’s often a good thing as an increased acid level helps with the digestion of food. Problems can arise when you drink too much coffee on an empty stomach. The overly acidic gastric juices can irritate the lining of the gut and cause heartburn.
It Helps Boost Metabolism
As a natural stimulant, coffee is also a metabolism booster. “Coffee not only helps the body burn fat, but as a diuretic, it keeps your digestion moving,” says Megan Roosevelt, RDN, LA-based registered dietitian nutritionist and founder of HealthyGroceryGirl.com. One study found that just one cup of coffee increased participants’ resting metabolic rate, energy expenditure, and fat burning for energy.

Coffee Makes You Poop
According to a study published in the journal Gut, “The speed at which the response occurs suggests an indirect action on the colon as it seems unlikely that coffee would reach the colon in this time either via the intestinal lumen or the bloodstream. We suspect that coffee may induce a ‘gastrocolonic response’ by acting on epithelial receptors in the stomach or small bowel. Such a mechanism could be mediated by neural mechanisms or by gastrointestinal hormones. Coffee has been shown to promote the release of Gastrin, which can increase colonic spike and motor activity.”

Digestive And Excretory Systems
Caffeine increases the amount of acid in your stomach and may cause heartburn or upset stomach. Extra caffeine doesnt get stored in your body either. Its processed in the liver and exits through your urine. This is why you might have an increase in urination shortly after having caffeine.
If you have experience stomach problems, like acid reflux or ulcers, ask your doctor if its okay for you to have caffeine.

Some of the symptoms don’t even require an overdose – they can occur with excessive consumption. However, due to the aforementioned habituation effect, this is usually harmless, so that many people can tolerate several cups of coffee in a row.

The researchers found that study participants who drank at least one cup of coffee a day had up to a 36 percent lower rate of suicideand this wasn’t the first group of researchers to make this discovery. Several other studies have hinted at an inverse association, too. Even so, it’s not yet clear if there’s something in the drink to thank or if coffee drinkers just happen to share common lifestyle factors that are often associated with a lower risk of suicide.

Does The Way Coffee Is Prepared Matter
Yes. Do you prefer a dark or light roast? Coarse grinding or fine? Arabica or robusta?
All of these different aspects affect the taste, but also affect the compounds within the coffees, said Neal Freedman, a senior investigator with the National Cancer Institute. But its not clear at all how these different levels of compounds may be related to health.
Roasting, for example, reduces the amount of chlorogenic acids, but other antioxidant compounds are formed. Espresso has the highest concentration of many compounds because it has less water than drip coffee.
A study in JAMA Internal Medicine examined the coffee habits of nearly 500,000 people in the U.K. and found that it didnt matter if they drank one cup or chain-drank eight regular or decaf or whether they were fast metabolizers of coffee or slow. They were linked to a lower risk of death from all causes, except with instant coffee, the evidence was weaker.
The way you prepare your cup of joe may influence your cholesterol levels, too. The one coffee we know not suitable to be drinking is the boiled coffee, said Marilyn C. Cornelis, an assistant professor in preventive medicine at the Northwestern University Feinberg School of Medicine and co-author of the JAMA Internal Medicine study.
Examples of this include the plunge-happy French press, Scandinavian coffee, or Greek and Turkish coffee the kind commonly consumed in the Middle East.
Circulatory And Respiratory Systems
Caffeine is absorbed from your stomach. It reaches its highest levels in your bloodstream within an hour or two.
Caffeine can make your blood pressure go up for a short time. This effect is thought to be attributed to either an increase in adrenaline or a temporary block on the hormones that naturally widen your arteries. In most people, there is no long-term effect on blood pressure, but if you have irregular heart rhythms, caffeine may make your heart work harder. If you have high blood pressure or heart-related problems, ask your doctor if caffeine is safe for you to consume.
An overdose of caffeine may cause rapid or irregular heartbeat and breathing trouble. In rare cases, caffeine overdose can result in death due to convulsions or irregular heartbeat.
Caffeine in large amounts may interfere with absorption and metabolism of calcium. This can contribute to bone thinning .If you consume too much, caffeine may cause also your muscles to twitch.
If experiencing caffeine withdrawal, a symptom may include achy muscles.
