Why do you get sleepy when you drink coffee, and what is going on the more you drink coffee, the mor

People vary in their sensitivity to caffeine. Some people drink coffee after noon and have insomnia at night; Some people drink a cup of strong coffee before going to bed and it does not affect sleep; Some people need to refresh their minds and coffee. All of these conditions are possible because people have different constitutions, so the degree of reaction, absorption, and excretion of caffeine is also different.

The answer to this question may vary from person to person, but the key is to have an understanding of your physiology and physical fitness.

It means that your body has completely adapted to caffeine and has no effect. If you want to refresh yourself, then you can do it another way, such as drinking green tea. After a period of time, you can switch back to drinking coffee, and it will have a refreshing effect again.

Some people drink coffee not only does not have a refreshing effect, but wants to sleep more and more, and there are several reasons for this condition:

1. Your institutional factors, you have a large number of powerful caffeine antibodies in your body, which resist the refreshing effect of coffee.

2. You drink coffee regularly, just like you drink alcohol regularly, and you can have a strong resistance to alcohol, and you have such resistance to coffee.

3. There are transformative or anti-coffee substances in the food or drink you enter at the same time.

4. You are in a state of extreme drowsiness, and the coffee has no energy that can resist your drowsiness.

The coffee you may drink is relatively low in caffeine and has more sugar, such as latte and cappuccino, you must know that when people absorb a lot of sugar, our blood sugar content will rise a lot when the sugar is consumed and decomposed, and we are easily sleepy.

The more you drink coffee, the more sleepy you are, which is caused by the increased tolerance of caffeine, and it will be better to reduce the consumption of coffee appropriately or stop using it for a period of time.

Everyone's nervous system is different, and nerves have different sensitivities to various caffeines. Some people are excited to drink coffee, while others are not excited or even sleepy, which is caused by individual differences.

Popular Science: Is it true that the more you drink coffee, the more sleepy you become?

Some people drink coffee more and more energetically, because coffee has a refreshing effect, if you drink more and more sleepy, it means that coffee has no effect on you.

It means that you are too sleepy, and your body is too tired to have this phenomenon, although coffee can refresh you, it will not work if you are too tired.

Hello, there are many reasons why you are still sleepy after drinking coffee, and the reasons may be different for different patients. If you are already extremely sleepy, drinking coffee with added sugar and your partner can have a hypnotic effect, because the cerebral cortex has entered a state of inhibition before receiving caffeine, and the patient will also have poor mental health, dizziness and other phenomena. Secondly, if the body lacks B vitamins, it may appear that drinking coffee will be more sleepy, mainly because coffee will make the body's metabolism too fast, and increase the consumption of B vitamins related to nerve and muscle coordination in the human body.

Daily work and rest should be regular, avoid overwork, avoid drinking coffee for a long time, excessive consumption, to avoid uncomfortable symptoms.

There are many reasons for feeling sleepy after drinking coffee, such as physical factors, the formation of antibodies after drinking too much coffee, the lack of B vitamins in the body, extreme drowsiness, etc.

1. What are the reasons for being sleepy when drinking coffee?

1. Physical factors. Feeling sleepy after drinking coffee may be due to the fact that there are a lot of strong caffeine antibodies in the body, which resist the refreshing effect of coffee.

2. Drinking coffee for a long time is easy to form antibodies, just as taking cold medicine for a long time will weaken the efficacy, the refreshing effect of caffeine is greatly weakened.

3. Lack of B vitamins in the body. Drinking a lot of coffee can cause the body's metabolism to be too fast, increasing the consumption of B vitamins related to the body's neuromuscular coordination. So, people who are deficient in B vitamins may feel more sleepy after drinking coffee.

4. Generally speaking, coffee can refresh the mind and relieve fatigue, but if the body is too tired and sleepy, drinking sweetened coffee and coffee companions can have a hypnotic effect.

It means that you are already very sleepy, and the coffee can't control you.

Everyone's adenosine receptors are not the same as their sensitivity to caffeine, which is genetically determined, so some people are born immune to caffeine. Maybe someone else takes a sip of the effect, you need to drink a whole cup to achieve it.

Another genetic determinant is the rate of coffee metabolism, some people drink coffee and are awake for a day, while others are only awake for an hour or two.

If you happen to be the type that is insensitive to caffeine and has a fast metabolism, it is basically useless to pour coffee no matter how hard you pour.

Going back to the principle of caffeine we talked about above - it actually prevents adenosine and adenosine receptors from working together to generate electricity with love. But if you drink it, adenosine and adenosine receptors have already combined, then caffeine becomes an awkward party, and you can't grab the socket.

So at this time, caffeine can only stand aside, watching adenosine make us sleepy.

Another possibility is that because of drinking a lot of coffee over a long period of time, which creates a tolerance, the brain releases fewer adenosine receptors. This is also why some people are "addicted to coffee", from one cup of spirit to two cups and still can't open their eyes.

Sugar can also be exciting, so you're probably on the verge of getting excited when you first get your sweetened coffee. But the insulin in your body will be quickly dispatched to help lower your blood sugar, and the sudden drop in blood sugar can make you feel sleepy, and sometimes accompanied by headaches, difficulty concentrating, dizziness and other symptoms.

If you are sleepy after drinking coffee, it means that you are very sleepy now, and coffee can't give you a refreshment.
