The reason coffee is argued that it is good or bad for the body seems to be a problem with the “caffeine” in coffee.
Caffeine can also cause headaches.
Drinking large amounts of caffeine will not help relieve headaches. For example, Caffeine can cause headaches indirectly by producing a lack of hydration if you increase your caffeine intake but not your water intake.
However, if you take too much or too often, caffeine is more likely to cause headaches because it leads to addiction.
If you take caffeine regularly (generally 200 mg or more per day for more than 2 weeks) and suddenly stop taking caffeine, you may experience caffeine withdrawal symptoms.
Changes in the brain caused by caffeine
People feel “fatigue” when two substances called “adenosine” and “adenosine receptor” in the human brain stick together. However, when caffeine is ingested, the caffeine that enters the brain in the blood binds to adenosine receptors, and adenosine cannot bind to the receptors, so people are less likely to feel tired. This is why drinking coffee makes you feel drowsy and refreshed.
However, as you repeatedly take caffeine, it becomes difficult for a small amount of caffeine to work on your brain. As a result, people become more tired, and the amount of caffeine gradually increases in an attempt to eliminate it, leading to “caffeine addiction.”
Disadvantages of overdosing
(1) Induction of stomach pain
Caffeine has the function of promoting the secretion of gastric fluid, and it can also cause stomach upset. Therefore, you should avoid caffeine intake on an empty stomach.
(2) Deterioration of sleep quality
Caffeine is a type of stimulant, so when you drink it, your body becomes agitated, it is difficult to fall asleep, and the quality of sleep may deteriorate. Avoid taking it 3 hours before going to bed.
(3) Disturbance of autonomic nerves
If you continue to take caffeine, which works on the sympathetic nerves that activate your body, your heart rate and blood pressure will continue to rise on a daily basis, and your body will always be in a state of excitement. As a result, the balance of the autonomic nerves is lost, and physical symptoms such as dullness and depressed mood appear.
The correct way to drink” is to enjoy coffee in a healthy way.
Not only is the taste delicious, but the effect is wide-ranging and, in addition to awakening drowsiness, the latest research shows that regular drinking will extend the lifespan. There are also reports that mochaccino effectively maintains concentration and reduces anxiety.
However, relying too much on energy drinks and coffee is a problem, and it seems that the dependence will increase and the result will be worse.
Count how many cups you drank.
When energy is low, you’ll want to reach for coffee, but if you don’t consume the right amount of coffee, things get worse. The appropriate amount varies from person to person, but according to the guidelines, 3 to 5 cups a day is acceptable. However, consumption within the guidelines should also be determined by personal taste and tolerance to caffeine, so drink. It’s important not to go too far. Too much coffee can lead to tremors, sleep disorders, stress, and anxiety.
Stop “coffee first.”
Many people won’t wake up in the morning without coffee, but in reality, it’s better to wait for a few hours.
It involves a chemical called cortisol, which awakens the body and sends a sign to move. When you wake up in the morning and drink your first coffee, it prevents your body from secreting the cortisol it needs and relies on caffeine to generate energy, so it’s a circadian rhythm (a 24 – hour cycle that adjusts your body clock).
