| In another study, it was found that caffeine reduced fatigue (Loke, 1988), however it also led to increased tension and nervousness (Smith, 2002). Also, Lieberman, 1992, stated that, caffeine seems to increase anxiety when administered in single doses of 300 mg or higher. Of course this is a lot more than a typical caffeine-containing beverage, again increased intake of caffeine, increased effects of mood changes. | In another study, it was found that caffeine reduced fatigue (Loke, 1988), however it also led to increased tension and nervousness (Smith, 2002).

| The participants that were included in the study were from ages 18-45, non-diabetic patients from a prospective study who were untreated of stage 1 hypertension, meaning they had systolic pressure of 140-159 mmHg and diastolic pressure of 90 and 99 mmHg. The way the patients were categorized was based on coffee consumption, by the number of caffeine-containing cups per day: so there were non-drinkers, which had no caffeine-containing cups, moderate drinkers who had 1-3 cups of caffeine-containing cups per day, and heavy drinkers who had 4 or more cups of caffeine-containing cups per day. So out of the participants then, 26.3% of them were abstainers, never had coffee, thus no caffeine-containing cups, 62.7% were moderate coffee drinkers and 10% were heavy coffee drinkers. The coffee drinkers, they noted, were older of the 18-45 age group and had a higher body mass index than the ones who did not drink coffee. From this study, Dr. Mos found that there was a linear relationship between the consumption of coffee, caffeine-containing, and risk of hypertension, needing treatment. This relationship actually had statistical significance for the heavy drinkers of coffee of this study. The study also found a linear relationship between long term coffee drinking and risk of developing prediabetes, with a 100% increased risk of prediabetes in the participants who were heavy coffee drinkers. This however, was true for individuals with slow caffeine metabolizers, and this was according to the CYP1A2 genotype, that decides if the individuals can metabolize caffeine faster or slower.

| + | The usual drinks that everyone consumes nowadays may or may not have caffeine in them. For instance, Hot chocolate could have up to 19 milligrams of caffeine per cup, Green tea has 20 milligrams of caffeine per cup, a shot of espresso has 27 milligrams of caffeine per container, and a can of cola has up to 40 milligrams of caffeine. Coca-cola and Pepsi beverages, in general, contain a high amount of sugar and caffeine, and most individuals are not aware of that. Since cola beverages have higher doses of caffeine in them, this could lead to heart arrhythmia due to caffeine toxicity, or caffeine overdose. Coffee has the highest amount of caffeine, almost up to 95 milligrams of caffeine per cup and just like cola beverages coffee overdose has severe side effects (Gromadzki, 2016). | ||

| + | The effects of caffeine are universal, meaning every creature who over-consume caffeine will be targeted to specific side effects. In this figure, These are spider webs made by spiders on drugs and toxins. The spider that has no chemical within its body; it is a normal spider, and the normal spider was able to create an intricate web. However, the spider on caffeine was not able to make an intricate design like an ordinary spider, fewer threads are joined, and the web was randomly created. The spider on chloral hydrate, which is used as either a sedative or a hypnotic pharmaceutical drug also has an irregular wed design. Therefore Caffeine could produce side effects if used severely just like any synthesized drug (Gromadzki, 2016). | ||
