How Caffeine Affects Sleep
Caffeine is perhaps the most popular drug worldwide. Found in many products, including tea, cocoa, energy drinks, and of course the coffee bean, many people use it in the morning after waking up. However, because caffeine is a stimulant, and it sometimes helps people to remain alert by blocking chemicals in the brain and increasing adrenaline production, what is important to know is how caffeine affects sleep. Although caffeine is safe to consume in moderation, heavy use may cause sleeping disruptions.
How Caffeine Affects Sleep
There are many factors, both external and internal, that can affect the quality and quantity of the sleep we obtain.
Internal factors
Sleep is regulated by two body systems, the circadian

It enters our system quickly and peaks within 30 to 75 minutes. When consumed, it gives us a quick boost in alertness, and may improve attention/reaction time. However, problems arise with processing the caffeine. The half-life, or the concentration of caffeine in the body to decrease by half from a single dose is three to seven hours, and the more you put into your system, the longer it takes to get rid of …show more content…
Other mild and chronic conditions may include;
$ Mild Sleep Disturbance
Study’s have shown that caffeine intake even six hours before bedtime results in significantly diminished sleep quantity and sleep quality. Since it takes six hours for caffeine to exit the body, ingesting more caffeine within that six-hour period extends its stimulatory effects, and reduces total nightly sleep amounts by more than 1 hour. Mild disruption of sleep can include waking up during the middle of the night with difficulty returning to a restful state.
$ Insomnia
Caffeine consumed in moderation is fine for many people, however, excessive caffeine can cause insomnia. People who consume more than 250 mg of caffeine per day are more likely than those who drank less daily to experience at least one symptom of insomnia at least a few nights each week. Caffeine-induced physiological arousal can have long-term repercussions on the sleep/wake cycle leading to chronic insomnia. Chronic insomnia includes being unable to fall asleep, to stay asleep or to have a restful sleep, and can cause daytime sleepiness, irritability and difficulty
Caffeine, a central nervous system stimulant, is the main psychoactive ingredient in energy drinks, which enhances alertness and mood, and counteracts symptoms of sleep. There is no doubt ...
By this definition, and after knowing the effects of caffeine upon the human body, I have come to the conclusion that drinking caffeine is a sign of a lack of respect for oneself, and of an unappreciative attitude toward the life that each of us has been blessed with. Furthermore, it shows of either our inability, or unwillingness to learn to think clearly.
Caffeine raises your blood pressure when you drink/eat it, raising your blood pressure in general is not a good thing but imagine drinking and/or eating caffeine daily, and your blood pressure constantly rising. Another negative aspect is that caffeine can have a disruptive effect on your sleep. The most obvious effect of the caffeine is that it can make it hard for you to fall asleep. It can help you stay awake during the day but can also make you stay awake during the night when you are trying to fall asleep. You can also have withdraws from caffeine, going back to the story “Java Man” the author Malcolm Gladwell considered it a drug and remember you can get addicted to drugs (you can really get addicted to anything). There are plenty more negative ways caffeine can disrupt your lifestyle but you know what they say for every negative thing you can say there can be some
Millions of people suffer from the same tossing and turning every which way, getting their sheets all disarranged and their insistent minds abundantly worse. Patients often proclaim indications of insomnia while sitting in the family health clinic. Insomnia traits include hindrance falling asleep, continueing to awaken, and rejuvenating before wanted. One may suffer from insomnia if one shows signs of an increased difficulty in attentiveness, decreased communal or scholastic skills, and a diminished mood or enthusiasm. (Foldvary-Schaefer 111). Countless individuals deal with insomnia for a large amount of their lives and some choose differing treatments, while some do not use any treatments at all. While never being uncommon, the amounts of causes leading to insomnia come in boundlessly; finding new studies and stories every day.
Caffeine is a mild stimulant that occurs naturally in at least 63 plant species. Caffeine can be found in the leaves, stems, seeds, and roots of these various plants. Caffeine is part of the methylxanthine family. It consists of a xanthine molecule with three methyl groups attached to it. Caffeine can be found in many products like sodas, tea, and coffee, but it also occurs in several other products such as prescription medications, diuretics, and pain relievers. Caffeine’s widespread use and popularity have caused many people to view the substance as an addictive drug. Thus making caffeine the most inexpensive and readily available drug known to man. Then on the other hand there are people who view caffeine as a helpful stimulant that increases the individual’s concentration and awareness as well as many other physical traits. The important thing to remember is that caffeine’s affects vary based on the person, the amount ingested, the frequency of consumption, and individual metabolism.

Caffeine is the most popular and most widely used stimulant in the world. In Canada, the average person drinks 2.6 cups of coffee a day; that is equivalent to 949 cups of coffee a year. (Van Houtte) Caffeine is a central nervous system stimulant that improves ones attention, focus, and fatigue. When caffeine is ingested it causes your neurons to move at a faster rate, increasing alertness. (Fit Day) Caffeine also binds to the neural receptors, which blocks the adenosine, which prolongs tiredness. Caffeine is a white odorless powder that is most commonly found in coffee, tea, energy drinks, and pops. Caffeine can also be considered and ergogenic aid. Ergogenic aids are external influences that enhance/ improves ones strength, endurance, reaction time and speed of recovery. (Healthline) The three theories that make caffeine an ergogenic aid during exercise is the effect it has on the central nervous system, skeletal muscles, and metabolic changes. (Sheila G. Dean) Caffeine also has a positive effect on an individual’s health, some positive effects include: reduces risk of developing liver cancer, Parkinson’s disease, and Alzheimer’s. (Chawala) Caffeine has been proven to have positive effects on an athlete’s performance, and ones overall health.
Sleep is one of our basic needs to survive and to function in day to day operations, but not everyone needs the same amount of sleep. Some people can survive on very little sleep, i.e. five hours a night, and some people need a lot of sleep, to the extend that they are sleeping up to 10 to sometimes 15 hours a night (Nature, 2005). According to Wilson (2005) the general rule states that most people need from seven to eight hours of sleep. The deprivation of sleep in our society in continually increasing with the demands in society increasing work loads, the myth that a few hours of sleep is only necessary to function properly and that sleep is sometimes considered as killing time (Nature, 2005). Sometimes sleep deprivation is also caused by other situations like sleep disorders, i.e. sleep apnea, chronic insomnia or medical conditions such as stress (Wilson, 2005).
As mentioned earlier, relying on caffeine to wake you up and keep you that way reduces your body’s ability to do that itself. The problem, one might argue, is not necessarily the coffee, but the school giving the student so much work that they have to stay up late enough to rely on coffee to keep themselves awake, or the teen’s lack of self-regulation staying up late doing pointless activities such as playing video games. And that one would have a point, except that we aren’t here to argue for educational reform or about “darn kids” and their video games. Those things are the source of the problem, but caffeine is a symptom that perpetuates itself and many other problematic symptoms. Even without school or video games, the problems associated with caffeine still
Caffeine on this energy drink blocks the effects of adenosine, a brain chemical that helps you sleep which is why too much can lead to insomnia.
As the vast majority of Americans are addicted to caffeine, studies show that the effects during post-consumption, can be positive or negative depending on the amount and frequency of caffeine intake. As the demand for caffeine has increased, the caffeine industry has increased its amount of marketing and establishments to help aid this demand. Caffeine addiction can lead to serious health detriments and physiological detriments. It is evident that the primary reason for consumption of caffeinated beverages is due to positive effects, such as alertness. The media has an abundance of marketing to continue to illustrate this main effect. The media fails to project the negative effects of excessive caffeine intake. This literature review will illustrate how excessive caffeine consumption can be detrimental to one’s life, and how problematic caffeine use derives from conditioning by the caffeine industries.
As side from that, excess caffeine can also overstimulate the central nervous system, disrupting sleeping patterns. High amounts of caffeine produce negative effect on sleep onset and quality. However, there are large individual differences in the effects of caffeine on sleep. Many people consume coffee during the evening and have no problems falling asleep, while others find that the mild stimulation of caffeine consumed shortly before a bed time delays the time to fall asleep.
Coffee is the first thing that people associate with instant energy on a groggy morning. “In the U.S., coffee is king of beverages” (Reinke) Research has been done that has named coffee as an addiction to the people who consume large quantities of it. Coffee was named the top source of antioxidants. This is partly because of the amount consumed each day. Some of the antioxidants that coffee has are quinines and chlorogenic acid. It also contains trigonelline, an antibacterial compound. This is where coffee acquires its delicious aroma. Now let’s step back for a minute and just think about how much caffeine people consume. In an 8oz cup of coffee it has about 85 milligrams of caffeine. This is about double the amount that tea contains. Studies have shown that caffeine stimulates the brain and nervous system. This is where you get that energized feeling. After about the third cup, knees start to bounce, pens are clicking and people start running laps around the office. Caffeine can become addicting if you drink too much. Coffee can become that addictive habit people are unable to shake.
Because sleep is vital to our well-being, we have to make sure to get an enough quality sleep at the right times as it helps to protect our mental and physical health, quality of life and safety.
Preview: The potential effects are related to the main ingredient in coffee – caffeine. Caffeine is a drug that stimulates the central nervous system that increases alertness and energy, but it is also very addictive.
Upon ingestion, caffeine connects with adenosine. Adenosine is a compound that builds up throughout the day and “runs” through your brain 's receptors, making you weary. Caffeine is similar to adenosine in structure and will work its way through the bloodstream into the brain. Once entering the brain, adenosine and caffeine compete and combine. Caffeine then takes over adenosines job and replaces your weariness with energy.
