Effects of Caffeine

Caffeine is said to leave an different kinds of effect on everyone and that it leaves an negative impact on people. I will be researching to find the negative impacts and effects that caffeine can leave on people. I want to prove that caffeine can have impacts on those who have consume it. The information that I’ve gather has shown us the kinds of energy caffeine leads to and how it impacts people careers or even themselves.

1) Curry, Kim; Stasio, Michael J. (2009). The Effects of Energy Drinks Alone and with Alcohol on Neuropsychological Functioning. Rowan University Libraries.

Usage: Caffeine is a source of energy that when mixed with different alcohol or sugary drinks can cause negative effects. The article defines the effects of mixed drinks with caffeine on people.

Qoute: “Caffeinated energy drinks—alone or with alcohol—are heavily marketed to young adults, many of whom believe that caffeine counteracts some negative effects of alcohol intoxication. “; “While participants who consumed the caffeinated beverage alone trended toward improved attention scores, neuropsychological status did not show meaningful changes from the pre- to post-test.”

Usage: This article helps me with finding how withdrawal affects people and what it does to them. I have found some information that I think will be useful to what I’m looking for on caffeine having a huge impact on people who can’t go a day without it.

Quote: “Caffeine withdrawal symptoms typically emerge after 12–24 h of caffeine abstinence, peak in the first day or two, and last from 2 to 9 days (Juliano and Griffiths, 2004). Caffeine withdrawal can impair normal functioning (e.g., incapacitating headache, missing work; Juliano and Griffiths, 2004, Strain et al., 1994), and it has been suggested that fatigue and performance decrements resulting from acute caffeine abstinence may have important implications for safety (e.g., sleepiness while driving) and academic achievement “

Quote: “Habitual caffeine consumers who abstain from caffeine experience withdrawal symptoms such as headache, fatigue, difficulty concentrating, mood disturbances, and flu-like symptoms (Juliano and Griffiths, 2004). The caffeine withdrawal syndrome has been documented across many experimental studies; however, little is known about how withdrawal symptoms co-vary during a discrete episode.”

Long-Term Effect of a Single Dose of Caffeine on Sleep, the Sleep EEG and Neuronal Activity in the Peduncular Part of the Lateral Hypothalamus under Constant Dark Conditions. MDPI.

Usage: This book will help me find out how people spend money on caffeine. Caffeine is shown to have the most amount of money that is spent by people who need it for a wake-up call in the morning or have a massive withdrawal.

Quote: “Caffeine is a central nervous system stimulant that influences both the sleep–wake cycle and the circadian clock and is known to influence neuronal activity in the lateral hypothalamus, an important area involved in sleep–wake regulation. Light is a strong zeitgeber and it is known to interact with the effect of caffeine on the sleep–wake cycle. We therefore wanted to investigate the long-term effects of a single dose of caffeine under constant dark conditions.”

Usage: To help find how our brain runs on caffeine and the effects it can have on people. Hyperflexion of your brain running in Java.

Quote: “The effect of caffeine on circulation and metabolism was studied during a discontinuous maximal oxygen uptake (VO₂ max) test on a bicycle ergometer. Eight male subjects were chosen for their minimal use of caffeine of which six normally did not ingest caffeinated beverages. Two caffeinated and two decaffeinated (control) trials were administered to each subject following double-blind and counterbalanced testing procedures.”

Usage: Caffeine is to be avoided before bed as sleep is an important part of our daily lives. Avoiding caffeine has become a way of helping improve people’s sleeping patterns as not taking caffeine it causes the mind to be healthy.

Quote: “Avoiding substances such as caffeine and alcohol before bed tends to improve sleep; Much has been written about the effectiveness of various sleep interventions, and sleep hygiene practices, such as avoiding caffeine in the evenings and having a routine bedtime, have become well known interventions for improving sleep quality.”(Sleep as an Occupation in College Students: A Mixed Method Study)

6) Alfajahan, Ohood Abdulrahman, Alfajahan. (2018). Sleep Habits and Caffeine Consumption in Undergraduate Female Students in Saudi Arabia. MS, Kent State University, College of Education, Health and Human Services / School of Health Sciences.

Usage: Each student has consumed a high amount of caffeine that has caused no difference in the amount of sleep. But has caused students’ awareness to increase due to the high amounts of caffeine.

Quote: “There were no significant differences in total caffeine intake between the caffeine consumers based on class standing (p = 0.840). Most participants fell into the high caffeine consumer group (82.5%, n=188) consuming more than 301 mg per day. Examining the total hours of sleep that each group obtained, there were no significant differences among any of the caffeine consumption groups (p=0.560) or by class standing (p=.056). More studies are needed to increase students’ awareness regarding caffeine intoxication and investigate the causes behind high caffeine intake and how to prevent caffeine related health issues.”

7) Sulaiman O. Aljaloud. (2016). Use of Energy Drinks Among College Students in Saudi Arabia. King Saud University.

Usage: It leaves students unable to perform academically due to the effects of caffeine which causes the body to overdrive all the time. An leads these effects to react negatively yo the body due to intake that was consumed.

Quote: “Even though the physiological mechanisms of caffeine are not well understood, caffeine
beneficially affects performance by reducing the perception of fatigue, enhancing central drive, and/or improving exercise capability.”

Quote: “For a college athlete, caffeine is rapidly absorbed in the human body, and performance effects can be maintained throughout an entire match. However, intake of
caffeine in the form of coffee yields smaller effects than intake of a similar dose of pure caffeine, plus there can be gastrointestinal distress associated with drinking strong
coffee. For college athletes, consuming even small doses of caffeine (1 – 2 mg/kg body mass) can influence reaction time, alertness, and visual information processing, which are crucial during exercise, practice, and competition. However, overdosing can negatively affect reaction time and alertness.”

Intake of caffeine from all sources and reasons for use by college students. National Library of Medicine; National Center of Biotechnology Information.

Usage: Coffee is a primary source of intake for college students as the energy is stronger than regular energy drinks which don’t provide them that must energy. It’s shown that most of our population of women have consumed more caffeine.

Quote: “As in the general U.S. population, coffee is the primary source of caffeine intake among the college students surveyed. Energy drinks provide less than half of total daily caffeine intake but more than among the general population. Students, especially women, consume somewhat more caffeine than the general population of individuals aged 19-30 but less than individuals aged 31-50.”

Usage: University students’ behaviors and sleep quality are impacted by the factors of caffeine intake, dieting, and exercise on their sleep patterns. Whether it’s advocating for balanced caffeine intake, examining dietary patterns, or understanding the roles of exercise in enhancing sleep, this research has the potential to inform strategies for better sleeping habits.

Quote: “Research has shown that university students engage in behaviors that are associated with poor sleep quality, such as higher caffeine and alcohol intake. Yet studies exploring eating habits and weight loss mechanisms related to sleep quality have generally been inconclusive. This study explored total daily caffeine consumption (along with different sources of caffeine) as well as dieting and exercising to lose weight in the last 30 days as risk factors for poor sleep quality among an undergraduate university population.”

Quote: ” Multivariable linear regressions were run to consider subjective sleep quality in relation to caffeine consumption and dieting behavior along with other covariates.”

10) Better Health Channel. (2022).Caffeine.

Usage: Better Health has given us some information on how caffeine can leave an impact on people and what they do. They tell us that caffeine can make you feel “anxious” and “sleeping” even harder with some of the effects that your body may experience.

Quote: ” In large doses, caffeine can make you feel anxious and have difficulty sleeping. Like many other drugs, it’s possible to develop a tolerance to caffeine, which means you need bigger and bigger doses to achieve the same effect.”

Quote: “Caffeine is well absorbed by the body, and the short-term effects are usually experienced between 5 and 30 minutes after having it. These effects can include increased breathing and heart rate, and increased mental alertness and physical energy. Depending on the individual, these effects can last up to 12 hours.”
