On Monday (12) the world celebrates the World Coffee Day, a pill that leads to one of the most popular drinks in the world. Part of the daily rituals of a large number of Brazilians, it brings important effects to those who want to start today, such as concentrating and reducing fatigue, but it can have risks if consumed without moderation.

“Inhibition of adenosine increases caffeine from the release of other neurotransmitters such as dopamine and narrinevin, which are associated with attention, warning and improving mood,” he said.
“There is a reasonable consensus on scientific literature on acute caravan effects, especially in fatigue or sleep deprivation. It can improve constant attention, the time of reaction and performance in repeated tasks.
Accordingly, the effect should last between 30 minutes and 6 hours in the human body, from one person to another. “The effect of the peak caffeine occurs between 30 and 60 minutes after swallowing, and the age of half of it can vary from 3 to 6 hours, depending on the person.”
The risks and side effects of coffee consumption
Velcisi also warned of the risk of wild coffee consumption, such as insomnia, anxiety, irritation, tachycardia, tremors and intestinal discomfort. She recommends this A daily dose of caffeine It does not exceed a sign of 400 mg, which corresponds to 4 cups of tense coffee.
“In some people, even small quantities can already lead to these symptoms,” he said. “To reduce these effects to a minimum, it is important to respect the limits of individual tolerance and avoid exaggerated consumption. Coffee distribution can help throughout the morning and early and avoid fasting or associated with other stimulating materials as well.”
The neurologist also indicates that pregnant women reduce daily caffeine intake to 200 mg. “The placenta crosses and can affect the fetus.”
Additional attention also extends to people with sleep disorders, generalized anxiety, cardiac arrhythmia, or esophageal carrots, whose symptoms may worsen with coffee consumption.
In addition, according to Filisi, caffeine tends to develop resistance and its effect may decrease over time in some people. In this case, the way to increase the dose that is taken, but to create a consumer strategy.
“Caffeine may not have the same positive effect on focus, and periodic breaks may be useful in” restarting the “body allergy”, “he said.
