I m still sleepy after drinking three cups of coffee a day, what is the reason and what should I do?

I recommend using free exercise to adjust, drinking three glasses is not effective, I think if you have been too tired lately and have not rested well, and you will be more sleepy when you drink in a sleepy state. It would be better if you had a drink in the early morning after breakfast. But don't blindly believe that with the effect of coffee you are more energetic, the key is to be able to integrate with the state of work, you will find that the effect of coffee is positive.

Caused by not enough rest. If you are still sleepy after drinking 3 cups of coffee a day, it means that you are overworked for a few days, and paying more attention to rest is the best solution.

1. Although coffee is a little helpful for sleepiness, it is not a medicine, and it is not good to drink too much, just like a fat sea, it is good for moistening the throat and throat, but it is also not good to eat too much, and it cannot be absorbed at once, so you can't drink too much at once.

2. We know that coffee is a stimulant drink, and if you drink too much, it will also put the rest of the nervous system in a state of excitement, so that you will be more sleepy.

3. It is recommended to drink a little more warm water every day and take a break if possible.

Drinking coffee can only play a temporary refreshment role, and it is useless to drink more, I don't know why you are so sleepy, if you are a student friend, it is recommended to drink Brand's chicken essence, which can play a role in eliminating fatigue.

Like me, drinking too much coffee doesn't work, try changing the tea.

I alternate coffee and tea, and it works.

The body is too tired! Nervousness, and other relationship reasons!

The weather has been bad lately, is it a cold?

Maybe you're resistant to coffee, drink some sports drinks, scream, or something.

Coffee doesn't have a refreshing effect on you anymore because you drink too much.

Coffee is not good. Or maybe you love to drink refreshing tea.

I grew up drinking milk tea.

The kind of coffee beans I drink don't have a pick-me-up effect.

Fatigue of the transition It is advisable to take a break to rest.

In this kind of weather, wash your face with cold water, make a cup of bitter tea, use the spiritual victory method, open your eyes in the mirror, and say, "Cheer up!" ”

Coffee can rejuvenate people when they are tired, but its efficacy varies from person to person. But why do some people get sleepier the more they drink coffee? Let me talk about it in more detail:

1. The principle of action of caffeine

Caffeine is 1,3,7-trimethylxanthine. can strengthen the work of the adrenal glands, i.e. glucocorticoids, aldosterone, adrenaline will increase the secretion. The increase in these hormones will bring indirect effects such as refreshment, concentration and so on.

Caffeine also has trimethyl, in the brain, caffeine will also antagonize adenosine A receptors, caffeine is equivalent to excites acetylcholinergic neurons, these neurons are mainly related to memory, association, learning, etc., so it has a positive "refreshing" effect on work and study.

2. The reason why the more you drink coffee, the more sleepy you become

1. Allergy to coffee.

People with allergies will have a faster metabolism after drinking coffee, and the metabolism should consume B vitamins. At this time, the consumption of vitamin B, which is related to the coordination of the nerves and muscles of the body, increases, then drinking coffee with a low level of vitamin B increases the amount of sleep.

2. Age factor.

As we age, there are fewer and fewer caffeine and receptors in the brain that can be docked. As a result, the effects of coffee on older adults are usually relatively small.

3. Genetic problems

Everyone's adenosine receptors are different in their sensitivity to caffeine, and some people's brains are more receptive to caffeine, which is especially effective for these people.

4. Improve immunity

If you drink a lot of coffee for a long time, the brain releases fewer receptors due to habit. The efficacy of coffee gradually decreases.

5. Practical factors.

In a state of extreme drowsiness, coffee simply has the energy to resist your drowsiness.

3. How to drink coffee correctly

1. A healthy adult should not consume more than 400 mg of caffeine per day, and pregnant and lactating women need to halve it.

2. It is suitable to drink coffee after breakfast and lunch, try not to drink black coffee on an empty stomach, and try to drink less coffee after 7 o'clock in the evening, otherwise it is easy to lose sleep.

3. People with habitual insomnia, the elderly, people with caffeine intolerance, and people with osteoporosis are advised to drink less or not at all.

4. Don't let the coffee cool. The longer coffee is exposed to the air, the more antioxidants are lost, and the less health benefits the coffee has. In addition, the acidity of coffee will become higher and higher, which can cause symptoms such as heartburn and digestive discomfort in the body.

Summary:In short, the effects of drinking coffee vary from person to person, but the most important way to refresh yourself is to get enough sleep!

Coffee is a great drink that has a refreshing effect, and coffee is widely consumed around the world. When you are sleepy after drinking coffee, it is more common in occasional situations, such as irregular work and rest for a long time, staying up late, and overdrawing at work.

Although coffee and tea have a refreshing effect, they are relatively speaking, and in the case of excessive fatigue and energy consumption, there will also be a state of sleepiness and fatigue. When there is often sleepiness and tiredness, it is also necessary to pay attention, such as their own trace element deficiency, nutritional imbalance, and some early diseases can lead to these symptoms.

Some people are not sensitive to caffeine, drink too much, and want to sleep when they are full.

It is true that coffee does not have much effect on sobering people, and people stubbornly believe that coffee will sober people, so they will drink coffee with wine, but it turns out that their reaction time and judgment are reduced. Studies have shown that college students who drink both alcohol and coffee are more likely to get into a car accident, so it's best not to drink coffee while driving.

There are also people who are overworked, jet lag, often stay up late, work night shifts, or lack of nutrients, or have some diseases in the body, resulting in low immunity of the body. Drinking coffee is exciting, and some people use it to relieve fatigue, but some people's physical fitness problems, situation problems, and their digestion and absorption problems, bearing problems, etc., can lead to some people sometimes being more sleepy.

When we wake up, the neuronal cells in the brain are very active, and they have to work hard to apply a large amount of kinetic energy. Adenosine triphosphate (ATP) is the pioneer of the body's professional production of somatic phosphogen, and they play with the hydrolysis reaction to release a lot of kinetic energy. After releasing kinetic energy, they go through a series of metabolisms and finally convert into a component called adenosine.

As the brain's working hours continue to increase, adenosine continues to accumulate in the brain and fuse with the corresponding receptors. Once the amount of adenosine binding to the receptor reaches a critical point, it becomes trapped. Caffeine, a unique ingredient in coffee, has a very special structure, which looks very similar to adenosine, so it can trick adenosine receptors in the brain and fuse with it.

The treacherous caffeine left the path of adenosine and left adenosine cornered. On the other hand, the honest brain could not detect adenosine, and did not receive the data signal of getting off work, so he worked diligently again. However, there are also prerequisites for this kind of extreme** to be used – drink coffee to wake up, opportunity is important, and drink it before you want to go to bed.

Because the key to the role of caffeine depends on preempting the opportunity to get ahead of the fusion of adenosine and receptors.

This still depends on the individual's physique, which varies from person to person, some people have a large amount of caffeine antibodies in their bodies, which can effectively resist the caffeine in coffee, and it is possible that they often drink coffee, and the effect is not obvious.

Because some people have different constitutions and are naturally resistant to coffee, they are still very sleepy after drinking coffee.

The function of coffee is to refresh the mind: Drinking coffee can refresh the mind. Coffee contains caffeine, which can improve nerve excitability and play a role in raising the mind. When you feel sleepy and sleepy during the day, you can make a cup of coffee to relieve fatigue.

2 is to be scattered in the world to ****: drinking coffee can be ****. The caffeine contained in coffee can increase the heart rate, which plays a role in increasing the body's metabolic rate.

3. Returning to the spine to eliminate edema: drinking coffee can eliminate edema. Coffee contains elements such as potassium, which can enhance kidney function and promote the excretion of excess water in the body through urine.

People with edema in the body can drink some coffee appropriately, which can play a role in eliminating edema. You or this should not be sensitive to caffeine!
