Does coffee really will make you a superhuman? A study by Robin Hanson from OvercomingBias.com indicated that we desired coffee way less than sex and sleep. The truth is anything with caffeine will taste better if you hadn’t had you fix of coffee before that. One way to become more productive is to drink a cup of coffee before taking a nap. Caffeine normally will take effect after 20 minutes of consumption. Here’s why you should get your caffeine fix in the morning with a cup of coffee:
Coffee Will Make You More Persuasive
A group of scientists set out of discover if this angle really works. Before giving university students either caffeinated orange juice or regular orange juice, scientists quizzed the students about their attitudes toward voluntary euthanasia or abortion.
After the beverages were consumed, scientists gave each student a persuasive text countering their stated attitudes on the subject they were tested on. They were then quizzed again about their attitudes toward the subject matter.
Students given caffeine were more easily persuaded by what they had read. It seems that caffeine makes you more attentive and, in doing so, makes you more easily persuaded. Also, caffeine puts people in better moods, which may also contribute to their being more easily persuaded.
The first experiment employed an orientating task whilst the second experiment employed a distracter task. In both experiments participants consumed an orange-juice drink that either contained caffeine (3.5 mg/kg body weight) or did not contain caffeine (placebo) prior to reading a counter-attitudinal communication.
The results across both experiments were similar. When message processing was reduced or under high distraction, there was no attitude change irrespective of caffeine consumption. However, when message processing was enhanced or under low distraction, there was greater attitude change in the caffeine vs. placebo conditions.
Furthermore, attitudes formed after caffeine consumption resisted counter-persuasion (Experiment 1) and led to indirect attitude change (Experiment 2). The extent that participants engaged in message-congruent thinking mediated the amount of attitude change.
These results provide evidence that moderate amounts of caffeine increase systematic processing of the arguments in the message resulting in greater agreement.
Coffee Has Shown To Reduce Depression On Women
Among a large population of women tracked for as long as 18 years each, the women who routinely consumed the highest levels of caffeine were 20 percent less likely than those who drank little to none to become depressed when they were nearing or in their 60s.
Coffee, which ounce-for-ounce delivers the strongest dose of caffeine, was most women’s pick-me-up of choice. And generally, the more caffeine a woman drank, the more likely she was to be in good mental health. The study was published Monday in the Archives of Internal Medicine.
“A small amount of coffee may keep you more active and more happy, and that may result in the long run in better brain health,” said Dr. Alberto Ascherio, the senior author of the study.
Cautioning that his group’s findings are preliminary, Ascherio added that they should ease concerns among female coffee addicts as they enter midlife; the average age of the participants was 63 years in 1996, when researchers began tracking the incidence of depression among the women.
Coffee And Donut Could Improve Your Brain Capacity
A study shows that caffeine and glucose can have beneficial effects on cognitive performance. However, neural basis of these effects remain unknown. The objective was to evaluate the effects of caffeine and glucose on sustained attention, using functional magnetic resonance imaging (fMRI).
How’s the study conducted? Forty young right-handed, healthy, low caffeine-consuming subjects participated in the study. In a double-blind, randomised design, subjects received one of the following beverages: vehicle (water, 150 ml); vehicle plus 75 g of glucose; vehicle plus 75 mg of caffeine; vehicle plus 75 g of glucose and 75 mg of caffeine.
Participants underwent two scanning fMRI sessions (before and 30 min after of the administration of the beverage). A continuous performance test was used to assess sustained attention.
Participants who received combined caffeine and glucose had similar performance to the others but had a decrease in activation in the bilateral parietal and left prefrontal cortex.
Since these areas have been related to the sustained attention and working memory processes, results would suggest that combined caffeine and glucose could increase the efficiency of the attentional system. However, more studies using larger samples and different levels of caffeine and glucose are necessary to better understand the combined effects of both substances.
How to get more caffeine out of coffee?
1) Consume in small, frequent amounts.
Between 20-200mg per hour may be an optimal dose for cognitive function.
2) Play to your cognitive strengths while wired.
Caffeine may increase the speed with which you work, may decrease attentional lapses, and may even benefit recall – but is less likely to benefit more complex cognitive functions, and may even hurt others. Plan accordingly (and preferably prior to consuming caffeine!)
3) Play to caffeine’s strengths.
Caffeine’s effects can be maximized or minimized depending on what else is in your system at the time. (Definitely add sugar. Grapefruit juice may prolong the effects of caffeine, while nicotine may speed up the body’s metabolism of it.)
4) Know when to stop – and when to start again.
Although you may not grow strongly tolerant to caffeine, you can become dependent on it and suffer withdrawal symptoms. Balance these concerns with the cognitive and health benefits associated with caffeine consumption – and appropriately timed resumption.
(For some, withdrawal from caffeine addiction can set in after 12-24 hours and last 2-9 days. Keep in mind that recall is best when the retrieval state matched the encoding state, i.e. if you were caffeinated when you learned it, be caffeinated when you’re trying to remember it.)
