What are the beneficial effects of coffee on intellectual performance and cognitive abilities such as memorization? Is the memory better? Here are 6 reasons why you should drink coffee.

1. The effect of coffee on memorization

Coffee is the most powerful antioxidant. What is the relationship with memory and the faculties of memorization? Research suggests that antioxidants have a positive effect on cognitive abilities, including memory. The results of a study of people aged 65 to 85 who do not have a memory impairment have been published in the journal “Rejuvenation Research”. 2 groups were formed: those who regularly took antioxidants and those who did not. After 2 months, the researchers noted a marked improvement in people’s information processing speed. making up the group that was absorbing antioxidants daily.

Wouldn’t the idea be to drink a lot of coffee to have a lot of antioxidants and therefore a capacity to memorization superior? If the idea is logical it is a mistake. Too many antioxidants can affect muscle oxygenation and interfere with physical activity, especially in the elderly.

Scientists at the Medical University of Innsbruck in Austria found that men performed significantly better in short-term memory tests after receiving a dose of caffeine equivalent to about two cups of coffee.

2. De-stressing effect of coffee

Coffee would have a de-stressing power. Curious paradox when we know that coffee has an exciting power. This is a context of lack of sleep. Indeed, lack of sleep generates a certain level of stress and therefore harmful to learning. Notice to students who party a little too much and find themselves sleep deprived.

3. Coffee and brain preservation, especially against Alzheimer’s disease

Drinking coffee regularly would preserve our brain against aging. Thus cognitive abilities would be particularly preserved in the elderly whose blood caffeine level is high. This was discovered by researchers from the University of Miami led by Chuanhai Cao in a study published in the journal “JJournal of Alzheimer’s Disease. » (2)

4. Effect on concentration and intelligence

Coffee won’t make you a smarter person. On the other hand, a good cup of coffee from the machine will give you a blow more energy in you will instantly improve your ability to concentrate and analyze. Thus your intellectual performance, without speaking of intelligence, will be much better than a person who, in the same sleeping conditions, will abstain from drinking a cup of coffee.

Harris Lieberman, a cognitive psychology researcher at the US Army Research Institute of Environmental Medicine, says that when you’re sleepless and take caffeine everything you do, including intellectual work, will improve: reaction time, alertness, attentiveness, logical reasoning – most of the complex functions you associate with intelligence. So you can look smarter. But just because you take caffeine from a cup of coffee doesn’t mean your intelligence or IQ will increase.

5. Coffee improves physical performance

Without being an athlete, if you have a physical performance to achieve, particularly in the context of a admission or an entrance exam that includes a physical test, a good cup of coffee should be able to help you improve your physical performance.

Many athletes know that a cup of coffee before a workout can boost performance, especially in endurance sports like distance running and cycling. Nothing magical about that. Caffeine has the effect of increasing the number of fatty acids circulating in the bloodstream. So the muscles can absorb and burn this fat for fuel. It is an additional energy reserve that is added to the more limited energy reserve of carbohydrates present in the body. Thus, caffeine (which is completely legal according to the rules of the International Olympic Committee), is the most popular substance in sports. For more than two-thirds of Olympic athletes caffeine in their urine has been found. The highest rate and therefore the most frequent and high use of caffeine is found among triathletes, cyclists and rowers. (4)

6. Coffee Reduces Depression and Suicide Rates

Drinking several cups of coffee a day appears to reduce the risk of suicide in both men and women by about 50 percent. This is the conclusion of a study conducted by scientists from theschool public health from Harvard (HSPH). The findings of this study were published online July 2 in The World Journal of Biological psychiatry. (5)

The scientists who did this study also looked at data from three large US studies and found that the risk of suicide in adults who drank two to four cups of coffee per day was significantly reduced compared to college students who drank decaffeinated coffee or very little or no coffee. How this explains ? Caffeine not only stimulates the central nervous system, but can act as a mild antidepressant by stimulating the production of certain neurotransmitters in the brain like serotonin, dopamine and norepinephrine. This could explain the low risk of depression among coffee drinkers.
