Scientific facts about how coffee affects human memory — does it really improve it

The belief about the dangers of coffee is firmly entrenched in the consciousness of modern man. And yet we cannot give up the mind-blowing fragrance, vivacity, energy and the special atmosphere associated with it. It turned out that not everything is so bad.

According to one study , a truly intriguing phenomenon is discovered: coffee really has the property of improving memory.

Other research proves that caffeine increases attention and improves mood.

So if earlier we just knew that Caffeine is able to activate the brain , now the details are being clarified, how and to what extent it affects our mental abilities. We will talk about this in the article.

Does a drink really improve memory?

How I wish that my favorite drink would not only cheer me up, but also have other useful properties. Today, experts are talking about the ability of this napik to enhance memory. Whether this is the case, scientists are still finding out.

Long-term

Michael Yassa from Johns Hopkins University (Baltimore, USA) and colleagues from neurophysiology have revealed the positive effect of caffeine on the ability to remember information. As a result of the experiment, it was confirmed that a cup or two of coffee brings tangible benefits:

  1. Noticeably improves human memory. It is about long-term memory. Moreover, the results of the "coffee lover" are on average 30% higher than those who do not consume caffeine.
  2. Reduces forgetfulness. As a rule, the effect is noted during the day after drinking this magical drink.
  3. Improves the consolidation of long-term memory. The result is observed during the day after drinking the drink. The brain is more discerning in looking for differences and performing other actions due to the effect of caffeine on the hippocampus (part of the brain).
  4. Concentrates attention and helps fight distraction. Focusing on the little things or other features eventually helps in memorization.
  5. Has a beneficial effect on attention, cognitive functions and mood. Improves performance.
  6. Affects declarative memory. This type of memory allows you to store a large amount of information.
To improve memory, you should not drink coffee in liters, eating it with kilograms of sweets. A high dose of caffeine can cause a backlash.

Short-term

Research by Valerie Lesk (International School of Advanced Studies, Italy) and Stephen Womble (Trinity College, Dublin) has produced an unexpected result: morning coffee drinkers often suffer from aphasia, or the phenomenon of the "tip of the tongue".

It consists in the fact that people cannot remember at the right moment some word that they know.

Short-term memory is responsible for this. Scientists explain this phenomenon by the fact that with increased attention and alertness caused by increased caffeine content, other areas of brain activity are shut down.

However, if it is necessary to recall information related to the current chain of thoughts, caffeine does not interfere at all.

Scientists suggest that women are more sensitive to the effects of caffeine than men.

5 more facts about the effects on the brain

The effect of caffeine on the human brain has not yet been fully studied. And if today scientists identify positive examples of the effects of the drink on people with Alzheimer's and Parkinson's diseases, then only time will tell what properties of coffee will be revealed in the future.

  5. Prolongs life. Increasingly, longevity and minimization of cognitive impairment (for example, increased resistance to Alzheimer's disease) are associated with caffeine consumption. However, this issue has been poorly studied so far.
