The crux of the matter seems to revolve around the caffeine that is found entirely naturally in the grains with which this drink is made. An interesting report published in a British newspaper, the Daily Mail, clarifies many doubts in this regard and responds to a large extent to the question:

How does coffee affect our body and mind?

We are going to break down the most exciting conclusions about the coffee consumption that is included in this article.

A study carried out by the Institute for Scientific Information on Coffee indicates that moderate consumption of coffee (such as those made from latte machines) – which is the one in Spain, between three and five a day – can reduce the risk of Alzheimer’s by up to 20 %. The figure is really important, and researchers say that the reason, of course, is in caffeine, which seems to act as brain trainer. This prevents the formation of protein plaques in the brain, which they say is intimately related to the onset and development of this disease. The antioxidants in this product are also vital, as they could relaunch the deterioration of brain cells. 

At a chemical level, caffeine works as a brain emitter, blocking adenosine, a substance that makes us feel tired. Therefore, when we drink coffee, we think that it activates us and give us that extra energy.

For those who ingest coffee regularly and in large quantities (such as Keurig owners who have a steady, near instant supply of coffee at the ready), their brain creates more adenosine receptors, so they need more coffee to stay awake. This explains why when we try to stop drinking coffee, we feel exhausted, since having more adenosine receptors, there is more of this chemical in our brain, increasing the feeling of fatigue. If you drink espresso, you should always go for good quality espresso beans available, they a tasty and very healthy.

Also, caffeine also promotes the production of adrenaline, which increases our heart rate, making our blood flow quickly and shaking our breathing. It also prevents dopamine (pleasure hormone) from being completely absorbed, so it acts longer in the brain. This is what makes caffeine addictive, so you have to be careful.

The effectiveness of coffee varies considerably depending on the person due to genetics and other factors. The effects of caffeine usually last around 6 hours. However, women who take oral contraceptives can feel the effect twice as long. Something similar happens in women who are between ovulation and the beginning of menstruation.

Does caffeine increase our mental performance?

Caffeine is known to be a stimulant of the central nervous system. Several studies have found that depending on the level of intake, it can help improve mental performance, especially in the level of alertness, attention, and concentration.

Caffeine makes us more awake in situations of reduced alertness or lack of sleep, for example, when driving at night, night work, flu, or drowsiness after eating.

Caffeine can help people with jet lag, or workers with the night shift, according to a study.

It is probably the best known and recognized effect of this drink so essential in our day-to-day. Who does not take it in the morning to wake up? A teacher from the University of East Anglia, concerning a series of reports and research studies, points out that the coffee to be activated is perfect. Increase blood pressure and heart rate. This is what makes us feel more energy, and we show ourselves more active. Caffeine stimulates the release of dopamine, which is to blame for the feeling of well-being, so again let us thank caffeine for how much-and good-it does for us, right? It is necessary to make a warning to those people with high tension and who are exceptionally nervous because it can become counterproductive.

You will find that there are plenty of coffee pots to choose from, and this source is just the reference to give your day the energy jolt it needs.
