Drinking a cup of coffee, like caffeine? Watch out for caffeine side effects


Caffeine. If you’re sleepy and tired but still can’t relax, your coffee will naturally go to you for help from caffeine.

Even if you’re not tired, you can find coffee after a meal, just like a habit.

I also visit coffee shops to chat with friends and family.

Is our health okay with coffee?


Be careful of coffee because of the caffeine it contains.

Caffeine is a kind of alkaloid that plants contain and acts as a stimulant when it enters our bodies.

Relieves fatigue, drowsiness and leads to slight mood swings.

So caffeine is easily addicted.

Poisoning also leads to resistance and withdrawal symptoms. If you take more than 250mg of caffeine per day, you can easily get these symptoms.


The recommended daily intake of caffeine in healthy adults is 400mg, so drinking it at the recommended intake is very dangerous.

The recommended intake of pregnant women is 300mg plus 2.5mg per kilogram of adolescents.

So what is the caffeine content in the coffee we usually drink?

Although it varies by coffee type, Americano is said to contain 150mg in 300ml.

Coffee does not contain caffeine alone, and most plant-based drinks contain caffeine.


Caffeine addiction can cause symptoms such as restlessness, nervousness, excitement, insomnia, hot flashes, digestive problems, muscle career, and frequent visits to the toilet.

Even if you are not addicted to the side effects should be careful.

Caffeine side effects include obstruction of blood circulation and elevated blood pressure, so people with high blood pressure and those with cardiovascular disease should take caution with ingesting caffeine.

It is not good for the digestive system, so gastritis patients should also be careful to take caffeine.

When children are addicted to caffeine, limit brain caffeine foods, such as stimulating brain hormones, which can lead to diseases like ADHD.
