[Transition: Let's start by talking about some of the positive ways caffeine affects your health.]
Body
Positive effects of caffeine A. Improves performance (Brentley, 2017). B. Increases Alertness (reason it is most often consumed) (Brentley, 2017).
Caffeine's effects begin about 15 minutes after consumption, alertness is one of the first signs of caffeine working (Brentley, 2017).
C. A 2009 University of Florida Study showed that drinking 3-4 cups of caffeinated beverages such as coffee in your 40s and 50s reduces the risk of dementia and Alzheimer's in your 70s by up to 70% (Sagon).
D. Reduces fatigue E. Ingesting around 200 mg a day of caffeine can boost long term memory (Whitemen, 2015). F. Controlling caffeine intake maximizes its positive effects (Smith, 2002). G. Caffeine is a stimulant (Whitemen, 2015).
Stimulants are known for improving mood (Whitemen, 2015).
Stimulants activate the central nervous system (Whitemen, 2015).
In 2013
All around the world, people drink coffee, tea and caffeinated drinks to wake up in the morning, to be more vigilant and alert throughout the day. Not only does this keep individuals alert but also allows them to focus and efficiently manage their time throughout their day. This quality of caffeine has caused it to be one of the most highly consumed psychoactive drugs. Individuals who require frequent intakes of Caffeine often feel tired, weak, drowsy if they tend to miss their cup of coffee early in the morning. Although, Caffeine is known for causing wakefulness and alertness it also has its downsides. If a person has a large dose of caffeine in a limited time, the drug could cause them trembling, anxiety and nausea. In long term effects,
Caffeine is a “naturally occurring chemical stimulant called trimethylxanthine” that presents itself much like other drugs such as heroin and cocaine (Brian). The buzz after a cup of coffee is an example of the similar properties. Caffeine “easily passes through body membranes” and enters the bloodstream
Caffeine is the most widely used drug in the world and the consumption in humans is constantly growing. Caffeine is found in a lot of the consumables that are ingested on a daily basis (Nawrot P., et al). Research claims that an appropriate and healthy daily intake of caffeine is approximately 400 milligrams. Research also shows that a large amount of caffeine intake a day has been proven to lead to several cardiovascular
About 80% of American adults consume 200 mg of caffeine a day. “A 12-oz. (tall) coffee from Starbucks will run you about 260 mg, while a 14-oz. Dunkin’ Donuts coffee contains 178 mg.” The daily intake of caffeine differed between products; one should always check the amount before consumption. There are no limits on how many energy drinks a person can purchase, which make it easy to abuse. Especially in younger children the addiction rate outstandingly high. Which may lead to other drug usage in the future and the committal dependence on stronger drugs.
Caffeine has many negative effects on humans, such as increased heart rate (Lane, J.D., 2002), depression (Goldstein, 2008), and addiction to this “drug.” You may be asking yourself, “What is caffeine?” Well, caffeine is actually a stimulant (Barone, Roberts, 2008) that is found in beverages such as tea, coffee, and soft drinks. In fact, caffeine is the highest grossing and most used stimulant in the United States (Barone, Roberts, 2008). It is estimated that 85% of adults living in the United States consume caffeine on a daily basis (Barone, Roberts, 2008). That means for every 100 adults, 85 of them have had a drink that contained caffeine on any given day. One reason caffeine is so widely available compared to other stimulants is
Caffeine will continue to have an effect on the body as long as it remains in the blood. The time required for the body to eliminate one-half of the total amount of caffeine consumed (or caffeine's half-life) varies from several hours to several days, but for the average non-smoking adult it is about 3-4 hours.
2. It makes it hard to sleep because caffeine has a 6 hour half life meaning it takes 24 hours to fully get out of your system.
A. Once caffeine is consumed, your body can completely absorb it within 30 to 45 minutes. Its effects will fade away within 3 to 6 to even 8 hours (“Caffeine”).
Many of us find ourselves drinking a freshly brewed cup of coffee, an ice-cold soft drink, a hot cup of tea, or an energy drink whether it be in the morning, afternoon, or in the night but one thing is that they all share a common ingredient: Caffeine
This article discusses the affects caffeine has on several aspects of human health. These included toxicity, cardiovascular effects (arrhythmia, heart rate, cholesterol and BP), bone/calcium balance, behavior, and reproductive and developmental effects. It also discussing the affect caffeine intake has on children and reproductive-aged women.
Although, it really doesn’t matter what time it is of the day caffeine is going down our throats all around the clock. Researchers have been verified that more than 90 percent of American adult’s drinks caffeine every day. Most of us drink it because, we may need that extra boost, and some feel they need it cause their so addicted to it. According to The Food and Drug Administration, the average person will drink up to 200 milligrams daily, the equivalent to drinking 4 cans of soda. Everyone seems to know already that sodas are not good for our body or health, but do you know the true effects that it does to the body?
