Why do you want to sleep from coffee and how to deal with it
There is a stereotype: to relieve fatigue and drowsiness, to cheer up and concentrate, you need to drink a cup of coffee. Did not help one portion – it means you need a second drink. Many of us look at those who claim that they want to sleep from coffee as unique, trying to demonstrate their exclusiveness. But perhaps coffee is indeed capable of lulling?
What explains the invigorating effect of caffeine?
To ensure the vital activity of human cells, energy is needed, which is released when the bonds in the ATP molecules (adenosine triphosphate acid) are broken. The greater the load on the body – the faster the ATP molecules decompose into adenosine and phosphates.
When adenosine in the cells becomes too much (that is, ATP reserves are exhausted), the brain’s adenosine receptors signal fatigue. Running processes «braking», during the time of rest in the body, ATP is synthesized and accumulated, and after a while the person is again ready to work.
However, caffeine has the ability to block adenosine receptors. As a result, the person stops feeling tired, and the body begins to draw energy from «emergency reserves». The coffee is invigorating, but if it is consumed too much, the ATP reserves do not have time to recover, and over time comes exhaustion.
Caffeine sleep effect
There are different types of adenosine receptors in the brain: some of them signal the need for rest, others – trigger the processes of awakening, contribute to the mobilization of all body systems. The receptors of the first group, as a rule, are larger, caffeine blocks them.
But sometimes, very rarely, deviations from the norm occur: some people have more receptors responsible for the state of cheerfulness. They take the caffeine punch. «Fatigue receptors» remain unblocked, the person relaxes, it seems to him that coffee lulls. If caffeine blocks the receptors responsible for vigor, the person falls asleep
Instant coffee: energy or sleeping pills?
Those who caffeine is not invigorating, not so much. Another phenomenon is much more common: a person experiences a surge of energy from a cup of natural coffee, but from a soluble one, on the contrary, becomes sleepy.
The fact is that the composition of coffee is not one, but two alkaloids that act on the body in the opposite way: invigorating caffeine and soothing theobromine. Theobromine in grains is significantly less, and it starts to influence the body when the effect of caffeine weakens: after about 40–60 minutes after drinking coffee. Some coffee lovers are generally not susceptible to small doses of theobromine, others feel a slight tingling in the kidney area: the alkaloid contributes to the narrowing of the renal vessels.
But the coffee bean is designed so that closer to its surface is higher concentration of caffeine, and in the center – theobromine. In the manufacture of instant coffee, the upper part of the grain is cut: from the raw material rich in caffeine, medicines and energy are produced.
In instant coffee, about as much caffeine as in natural arabica, and theobromine much more. And here everything depends on the physiology and the power of persuasion. If a person drinks instant coffee in the morning before work, when the body is still supposed to mobilize, then you may not realize that the drink is not very invigorating. But on the one who is very tired and wants to get rid of sleep, instant coffee does not always have the desired effect.
Hence the conclusion: with extreme tiredness, it is better to drink natural coffee, sometimes soluble only increases drowsiness.
Caffeine Relaxation Factors
It so happens that a person regularly drinks coffee for a long time, but from a certain moment begins to notice that the favorite sensation of cheerfulness does not cause a favorite drink. This means that the body has adapted to the periodic intake of a substance blocking adenosine receptors, and has developed a compensation mechanism. To avoid addiction, you need not to increase the daily portion of coffee, but at least for a few weeks to abandon it altogether. Then 1–2 days a week replace chicory coffee or rooibos
The invigorating effect of coffee significantly weakens the milk and cream. Milk protein slows down the absorption of caffeine, and if there is a lot of milk – alkaloid action is almost neutralized. Therefore, a tired person after a cappuccino or latte often begins to sleep.
Many people become refractory to caffeine after consuming high-calorie, fatty foods, including cakes and cakes with butter cream. Nature laid down in the human body the need after a hearty lunch a little sleep (all predators do this). And the caffeine contained in an espresso cup is not enough to conquer this physiological need. Also, the invigorating effect of caffeine is weakened, if you drink a few glasses of water before coffee, eat a rich broth or soup.
Strong sleepiness causes coffee with cognac, whiskey or rum. Caffeine and alcohol create a serious load on the vessels and the liver, the body spends a lot of effort to neutralize the action of alkaloids, because of which a person feels tired.
How not to fall asleep after coffee
There are several ways to enhance the invigorating effect of caffeine:
- give preference to black coffee without milk, cream and sugar;
- do not drink water for 1.5–2 hours before drinking coffee;
- before drinking coffee there are light vegetable dishes;
- Do not eat a drink of cakes or pies with cream, desserts with cream, sour cream, ordinary cottage cheese or mascarpone.
If you want to sleep after instant or natural coffee, in order to cheer up, you can apply the folk methods:
- drink a glass of grapefruit juice;
- The recipe for a stronger remedy for drowsiness is based on the recommendations of Professor Neumyvakin. Add 10 to a glass of water at room temperature.–15 drops of 3% hydrogen peroxide solution and mix. The liquid should be drunk as soon as possible. The tool will be even more effective if the water is replaced with a chilled rooibos.
