Most people know that drinking coffee helps them feel more energized. and relieves drowsiness and drowsiness (Even if you’re not a coffee drinker) many people are addicted to drinking coffee to help relieve fatigue and sleepiness. But some people argue stubbornly. That drinking coffee doesn’t seem to help anything. Drinking it makes me feel sleepy. Some people solve this by drinking stronger coffee. hoping that the strong caffeine content would help lift loose eyelids. What happened was the opposite. Didn’t even finish half a glass. He fell asleep with his head in his coffee cup.
Symptoms that cause you to feel sleepy after drinking coffee are symptoms that can occur. But why is that? Even though drinking coffee that contains caffeine is supposed to make us sleepy. Open your eyes. This story has an explanation.
Caffeine as we know it
If talking about caffeine (Not heroin) 100% will think of coffee first. Followed by tea, soft drinks and energy drinks. Caffeine as we know it It has the ability to act against substances that cause drowsiness in the brain. which is the substance adenosine (adenosine) which causes people who drink coffee Or get caffeine into the body so it doesn’t feel sleepy. and feel alert
Adenosine is a type of neurotransmitter. that accumulates within nerve cells Because normally Adenosine is produced by using the body’s energy. The more energy you use, the more tired your body becomes. This causes this substance to accumulate in the brain. It will make us sleepy. The higher the level of adenosine in the nervous system, the more alert the brainstem is. will only be associated with increased levels of sleepiness. The intake of caffeine into the nervous system therefore acts to inhibit the activity of adenosine within the brain. Stimulate the brain and body to be alert.
Drinking coffee can counteract the action of adenosine in the brain. This is only when adenosine has not yet bound to receptors in the brain. (I haven’t caught it yet, but I’m still not sleepy.) Therefore, if you drink coffee to stay awake. You should drink it before you feel sleepy. But if you’re sleepy then drink it. The properties of caffeine may not help you stay awake much. We have to wait for the brain to process this set of adenosine first (or go to sleep) before we feel more refreshed.
The body receives caffeine It increases the activity of the neurotransmitter dopamine (dopamine), which causes the brain to be alert. In addition, it was found that there may be an increase in the amount of serotonin (serotonin), which has an effect on mood. This will make you feel satisfied and happy.
Drink coffee and feel sleepy.
Normally, coffee has a wakefulness-stimulating effect that lasts for 15-30 minutes. Soon after that, Caffeine will be metabolized. Then the body will gradually Go back to being sleepy or tired as usual. That makes us have to find coffee to drink again to wake up the sleepy state.
But who drinks coffee regularly? The body will adjust to the amount of caffeine it receives. When the body gets used to it, it releases more adenosine. (Trying to beat each other) When drinking the same amount of coffee, the sleepiness did not stop. Plus, the amount of time awake is getting shorter and shorter. At a certain point The body will enter a state of caffeine tolerance. It turned out that taking caffeine to make me feel sleepy didn’t work. After eating, I feel sleepy.
In other words, the caffeine in สมัคร ufabet coffee blocks adenosine receptors in the brain. to prevent them from catching together But caffeine does not stop the production of adenosine. And it doesn’t create anything to block the increase in adenosine receptors. This means that when the effect of caffeine wears off, The brain also accumulates adenosine that needs to bind to receptors. Until leading to fatigue and exhaustion
This is a simple explanation. That the more we are addicted to coffee, drinking for a long time We will feel that the same amount of coffee cannot make us as alert as before. The effect of caffeine in subsequent cups of coffee decreases, causing caffeine tolerance. And it makes us crave even more caffeine. The more days you sleep, the less you sleep. The symptoms of exhaustion are getting worse. That whole day you will feel sleepy, dizzy, confused, even though you’ve already drunk coffee.
Aside from that There are some other factors that cause our body to not respond to caffeine as well as it should, such as:
Caffeine has a responsive effect on the cardiovascular system. Some people drink coffee and their heart palpitates. fast heartbeat Causes fatigue from a rapid heartbeat. Until we feel like we’re sleepy, when in reality we’re just so tired that we want to rest.
debt to sleep From not getting enough rest, staying up late, sleeping little, sleeping at irregular times, not sleeping well, or sleeping less than 6 hours per day for a long time. Adenosine, which often induces sleep, therefore delays the onset of sleep. and has more strength It causes drowsiness after drinking coffee.
Coffee has a mild diuretic effect. Drinking coffee can make you urinate more often than usual. Therefore, the body is dehydrated to maintain blood pressure and blood circulation. Dehydration can cause your heart to beat faster and your blood pressure to drop. leading to feelings of fatigue and sluggishness
Caffeine causes blood vessels to constrict. Makes some blood vessels narrow Losing fluid can disrupt blood flow to various parts of the body. Losing fluid can also make your heart beat faster.
Sugar in Coffee Some people are not addicted to caffeine. But you may be addicted to the sweetness from coffee. Especially those that add syrup or whipped cream. Or do you wear this every time you drink iced coffee? Normally, the body uses sugar more quickly than caffeine for energy. After the body has used up all the sugar We will feel like our energy is low (sugar drops), so we are exhausted and feel sleepy.
Drinking coffee late in the day or after noon. In some people, it may cause the quality of sleep during the night to be worse. Having insomnia, not getting enough sleep because caffeine wakes up the brain Even though the body wants to sleep fully Make it really time to go to bed. We should sleep deeply. Some people drink coffee and sleep normally. But that doesn’t mean you’ll sleep effectively. I woke up so I was tired.
Not everyone responds to caffeine the same way. Some people are sleepy even before the cup of coffee is finished. Some people feel sleepy after drinking just one glass. while others can drink several glasses per day. and did not feel that there were any negative effects on health
How to relieve sleepiness after drinking coffee

It will help your body adjust by gradually reducing the amount of coffee you drink from 2 cups a day to one cup a day.
