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.

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.”

    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. One theory is that caffeine could be a contributing factor, which makes a lot of sense. Caffeine was shown to reduce the loss of dopamine , according to the report.

    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.
