A bane and delight for coffee lovers, caffeine is a substance with many beneficial properties for the body that can, however, have a negative impact on sleep quality. In fact, the best known and most exploited <\/span>effects of caffeine<\/b> are its energising ones, which, on the other hand, can impede the laced sleep-wake cycle.<\/span><\/p>\n

But how do you manage caffeine intake correctly? How much coffee can be consumed per day to get a good night’s sleep?<\/span><\/i><\/p>\n

To fully enjoy the pleasure of coffee without worries, it is essential to fully understand what caffeine is and how it interacts with our body. In this article, we will explore in detail all the facets of this precious plant alkaloid and its many functions.<\/span><\/p>\n

Meanwhile, know that <\/span>moderate caffeine consumption does not affect sleep quality<\/b>. On the contrary, we who know about coffee can state with certainty and based on numerous scientific studies that <\/span>caffeine<\/b> has<\/b> several benefits for the body<\/b>: it stimulates memory, improves sports performance, gives energy and has a positive effect on mood.<\/span><\/p>\n

What is caffeine<\/span><\/h2>\n

Known for its energising and stimulating properties, caffeine is a <\/span>natural alkaloid<\/b> found in <\/span>coffee, cocoa and tea plants<\/b>.<\/span><\/p>\n

In the coffee plant, it is one of the most present molecules and, in nature, has a very specific function: it drives herbivorous animals away from the plant.<\/span><\/p>\n

Its <\/span>energising and protective properties<\/b> are activated even when small quantities are ingested. For this reason, the substance is effective even in small doses, both in plant protection and on the human organism.<\/span><\/p>\n

Its effects on the human body are due to its special molecular structure, which is able to stimulate receptors in the central nervous system.<\/span><\/p>\n

As we have seen, it is extracted from certain plants in particular, but there are many drinks on the market with caffeine added. In small doses, caffeine has <\/span>several beneficial properties<\/b>. Given its ability to interact quickly and intensely with the body, however, it is essential to be aware of its effects and not to abuse it, in order to avoid unpleasant adverse consequences.\u00a0<\/span><\/p>\n

Caffeine acts as a stimulant in various biological systems, affecting the central nervous system, the cardiovascular system, gastric acid secretion and metabolism.<\/span><\/p>\n

What caffeine actually does<\/span><\/h2>\n

Caffeine is a lipophilic molecule that interacts quickly with the body.<\/span><\/p>\n

When you take a caffeine drink, be it coffee, tea, chocolate or an energy drink, it starts to take effect in just <\/span>twenty minutes<\/b>. Its absorption takes place in the intestine, from which it quickly reaches the blood. Through the bloodstream it reaches the liver, where it is metabolised.\u00a0<\/span><\/p>\n

What does caffeine do to our bodies? What is its stimulating effect due to?<\/span><\/i><\/p>\n

The particular molecular structure of caffeine allows it to easily penetrate through the blood-brain barrier, from where it reaches the neurons.\u00a0<\/span><\/p>\n

In the brain it replaces adenosine, the neurotransmitter that regulates the feeling of tiredness, and blocks its action. As a result, when drinking coffee, the body does not feel sleepy or want to rest.\u00a0<\/span><\/p>\n

In addition to inhibiting the regular activity of receptors deputed to relaxation, it <\/span>stimulates the production of adrenalin and noradrenalin in the blood<\/b>. The effects of this mechanism are well known: <\/span>you feel increased arousal, you do not feel tired, your concentration increases, your pulse quickens and your blood pressure rises.<\/b><\/p>\n

Caffeine also has an effect on <\/span>improving mood<\/b>, mediated by another neurotransmitter, <\/span>dopamine<\/b>. In some neurons, adenosine acts on dopamine receptors, preventing their binding and thus blocking their effect. Again, caffeine, by preventing adenosine from binding to these receptors, reflexively increases the action of dopamine.<\/span><\/p>\n

This would also explain caffeine’s positive effect on the prevention and progression of Parkinson’s disease, a condition linked to dopamine deficiency.<\/span><\/p>\n

Pleasant sensations, however, occur at low doses of caffeine (below 500 mg): at higher doses, feelings of agitation, restlessness, anxiety, tremors and insomnia tend to prevail. These are reversible effects due to excess caffeine, which <\/span>disappear when consumption is reduced<\/b>.<\/span><\/p>\n

There is also an adaptation mechanism in our brains whereby, if the adenosine receptors are continuously occupied by caffeine, the body produces more of it so that adenosine can bind. When this happens, the usual dose of coffee is no longer enough, and we have to increase it to get the same effect. Again, this is a reversible mechanism by reducing caffeine consumption.<\/span><\/p>\n

The concentration of caffeine changes depending on how the coffee is prepared<\/span><\/h2>\n

In many cases, it is recommended <\/span>not to exceed three cups of coffee a day<\/b> in order to limit the percentage of caffeine in the body. However, this is too general and in no way corresponds to reality.<\/span><\/p>\n

The <\/span>concentration of caffeine in coffee<\/b> is not the same for every type of coffee but varies mainly according to the method of preparation and the quantity and quality of powder used.\u00a0<\/span><\/p>\n

In particular, unfiltered coffee, <\/span>cuccumella<\/span><\/i> (the typical coffee machine of Naples), traditional mocha and the gravimetric percolation extraction method have a higher caffeine content; espresso has a medium content; soluble coffee has the lowest caffeine level.<\/span><\/p>\n

The <\/span>roasting of coffee<\/b> strongly influences the caffeine concentration. During the roasting process, different coffee varieties are mixed, each with its own caffeine percentage. Coffea robusta beans are the most concentrated, while <\/span>coffea arabica<\/span><\/i> is more intense.<\/span><\/p>\n

Benefits of caffeine<\/span><\/h2>\n

The <\/span>beneficial effects of caffeine<\/b> are extolled by all lovers of espresso and energy drinks and relate to increased energy, improved brain activity and increased alertness. These results are real and also medically confirmed, especially for healthy individuals who are not taking drugs incompatible with the molecule.<\/span><\/p>\n
