Delicious coffee is a great start to the day, a boost of vivacity and just a fragrant drink. Without him, the morning is not good.
What is so special about him?
Is coffee and caffeine it?
Yes, the vitality is the merit of caffeine. But it is not only found in coffee.
Caffeine is found in various foods, such as tea leaves, cocoa beans, and cola nuts.
By the way, some scientific studies prove that green tea and cocoa can invigorate even more than coffee. That is why these drinks are recommended to be drunk before 3 pm.
No matter how many variants of caffeine exist in nature, we still prefer a cup of dark invigorating drink. Well, you get the idea - coffee.
And if we choose coffee for a boost of vivacity, then there is much more caffeine in ground from natural grains.
In soluble it is several times less. Therefore, the hand is still trying to mix itself another mug of "nescafe" to cheer up, but there is zero sense.
Important!
For the production of instant coffee, the upper shell of the grain is removed, which contains a large amount of caffeine, and then it is used separately - in pharmacology, for the preparation of medicines.
Cheerfulness from coffee in terms of biochemical processes - how does it work?
The human brain contains many adenosine receptors, which, among other tasks, regulate the mechanisms of sleep and wakefulness.
The desire to sleep is caused by adenosine, but caffeine is similar in molecular structure, and it replaces adenosine, preventing it from binding to receptors. That is, in other words, we stop wanting to sleep.
Important!
Coffee is quickly excreted from the body and no traces of caffeine are detected after 2.5 - 3 hours.
However, our receptors still remain blocked for another 5-6 hours.
This explains the recommendations to drink coffee a few hours before bedtime, otherwise you will not be able to fall asleep or it will be possible, but with difficulty.
After a specified time, the receptors return to normal and can again combine with adenosine.
And yet, there are people, an exception to the rules of action of caffeine, whom coffee puts to sleep.
Research confirms that gene combinations and other redistribution of receptors in the brain are to blame. Sometimes it starts to get sleepy after a cup of coffee, this is due to the fact that caffeine blocks other receptors, which are just responsible for vigor, it is intolerable to sleep.
Night shift and liters of coffee = cheerfulness?
No. It doesn't work that way.
Some believe that the more coffee you drink on a sleepless night, the more cheerful they will feel. But it doesn't work.
Approximately 2-3 cups of coffee block almost 50% of the receptors and the effect lasts 5-6 hours.
A few extra cups of coffee will not give you any particular vigor, but only increase fatigue and by the morning there will be an unpleasant state of "brokenness".
By the way, the invigorating effect of coffee can be enhanced without drinking it in buckets.
Scientists have recently conducted a number of studies and found that the maximum energy boost from one cup of coffee can be obtained by combining it with grapefruit juice or a slice of grapefruit.
Good performance was also observed in coffee with lemon, but orange juice did not give such an effect.
However, the bright effect of "agitation" and increased efficiency, in any case, was observed for no more than an hour.
But milk or cream, on the contrary, slows down the effect of vigor, but at the same time prolongs its effect.
If you need to maintain a stable concentration over several hours, it is better to drink a cup of coffee with milk.
Conclusions on coffee vigor:
- only ground and freshly brewed coffee
- coffee + lemon or grapefruit = double vigor
- more than 3 cups of coffee a day = zero energy
Health to all!
