Most people know that drinking coffee can make them feel more energized. and relieve drowsiness and yawning (Even non-coffee drinkers) make many people addicted to coffee to help relieve fatigue and drowsiness. But some people argue stubbornly. That drinking coffee doesn't help anything. I'm still sleepy after drinking. Some people fix this by drinking stronger coffee. in hopes that the strong caffeine will help pull the sagging eyelid up. What happened was the opposite. Didn't even get to drink half a glass. He fell asleep with his head down in the coffee cup.
Symptoms that drink coffee and drowsy is a symptom that can occur. But why is that? Even though drinking coffee with caffeine should help us stay stunned. eyes open This story has an explanation.
Caffeine as we know it
When it comes to caffeine (Not heroin) Hundreds and hundreds will have to think of coffee first. followed by tea, soft drinks and energy drinks. Caffeine as we know it It has properties that act against substances that cause drowsiness in the brain. which is a substance adenosine (adenosine) causes people to drink coffee Or get caffeine into the body so it's not sleepy. and feel awake
Adenosine is a neurotransmitter. that accumulates within the nerve cells because normally Adenosine is produced by the body's energy use already. The more energy used, the weaker the body. causing this substance to accumulate in the brain will make us sleepy The higher the level of adenosine in the nervous system in the brainstem, the higher the level of adenosine. It is only associated with increased sleepiness levels. Caffeine enters the nervous system, thereby inhibiting the activity of adenosine within the brain. Stimulate the brain and body to be alert.
Drinking coffee can counteract the activity of adenosine in the brain. only when the adenosine has not bind to the receptors in the brain (I haven't caught it yet, I'm not sleepy), so if I drink coffee to stay awake should drink before getting sleepy But if you're sleepy, then drink The properties of caffeine may not be of great help to alertness. We have to wait for the brain to deal with this set of adenosine substances (or go to bed) before we feel refreshed.
the body getting caffeine It increases the activity of the neurotransmitter dopamine, which causes the brain to be alert. It has also been found that there may be an increase in the amount of serotonin, which affects mood. which will make you feel satisfied and happy
Drink coffee and feel sleepy
Usually, coffee has a stimulating effect that lasts for about 15-30 minutes. Caffeine will be metabolized. Then the body will gradually return to sleepy or tired as before. That means we have to find a new coffee to drink to awaken the state of drowsiness.
But who drinks coffee regularly The body will adjust to the amount of caffeine received. When the body gets used to it, it releases more adenosine. (Trying to beat each other) when drinking the same amount of coffee, so it doesn't disappear. Plus, the duration of being awake is getting shorter and shorter at some point. The body goes into a state of caffeine resistance. It turns out that taking caffeine in order to get rid of drowsiness doesn't work. I feel sleepy after eating.
In other words, the caffeine in coffee blocks adenosine receptors in the brain. so that they don't catch each other But caffeine does not stop the production of adenosine. And nothing was created to block more adenosine receptors. This means that when the caffeine effect is exhausted. The brain also accumulates adenosine that wants to bind to the receptor. leading to fatigue
This simply explains that the more coffee we are addicted to, the longer we drink it, the more we feel that the same amount of coffee won't keep us awake. The effect of caffeine in subsequent cups of coffee decreases, becoming intolerant to caffeine. And it makes us need more caffeine. The more days I sleep less Fatigue became more severe. That day all day, I feel sleepy, dizzy, confused, even though I already drink coffee
