| Video Discription | Coffee and more specifically caffeine is something that we associate with increased performance, both physically and mentally. But is there actually evidenced that it can increase your memory and more specifically your exam grades? If so, when is best to drink your coffee? The morning? The afternoon? Before studying? After studying? The Bottom Line: Well, the evidence suggests, both before and after studying will still enhance your memory. And drinking in the morning may be more beneficial than in the afternoon. The Warnings: Some of these studies has several limitations. For example the first study has small sample sizes and students were selected from a single centre making them not representative of the wide student population. It also doesn’t use pragmatic exams or totally account for all confounding factors. The Heath Warning: Caffeine isn’t for everyone and it certainly shouldn’t be consumed in large doses. Don’t exceed to recommended daily amount for your age and gender. Be sensible and safe out there! #shorts #coffee Evidence for drinking coffee BEFORE studying: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5107567/ Many college students struggle to perform well on exams in the early morning. Although students drink caffeinated beverages to feel more awake, it is unclear whether these actually improve performance. After consuming coffee (caffeinated or decaffeinated), college-age adults completed implicit and explicit memory tasks in the early morning and late afternoon (Experiment 1). During the morning, participants ingesting caffeine demonstrated a striking improvement in explicit memory, but not implicit memory. Caffeine did not alter memory performance in the afternoon. In Experiment 2, participants engaged in cardiovascular exercise in order to examine whether increases in physiological arousal similarly improved memory. Despite clear increases in physiological arousal, exercise did not improve memory performance compared to a stretching control condition. These results suggest that caffeine has a specific benefit for memory during students’ non-optimal time of day – early morning. These findings have real-world implications for students taking morning exams. Evidence for drinking coffee AFTER studying: https://hub.jhu.edu/2014/01/12/caffeine-enhances-memory/ Johns Hopkins researchers conducted a double-blind trial in which participants who did not regularly eat or drink caffeinated products received either a placebo or a 200-milligram caffeine tablet five minutes after studying a series of images. Salivary samples were taken from the participants before they took the tablets to measure their caffeine levels. Samples were taken again one, three, and 24 hours afterwards. The next day, both groups were tested on their ability to recognise images from the previous day's study session. On the test, some of the visuals were the same as those from the day before, some were new additions, and some were similar but not the same. More members of the caffeine group were able to correctly identify the new images as "similar" to previously viewed images rather than erroneously citing them as the same. The research is different from prior experiments because the subjects took the caffeine tablets only after they had viewed and attempted to memorise the images. Almost all prior studies administered caffeine before the study session, so if there is an enhancement, it's not clear if it's due to caffeine's effects on attention, vigilance, focus, or other factors. By administering caffeine after the experiment, we rule out all of these effects and make sure that if there is an enhancement, it's due to memory and nothing else.
