The world celebrates the World Coffee Day this Monday (12), leading to one of the most popular drinks in the world. As part of a significant number of Brazilian daily ritual, it can bring important effects such as concentration and fatigue reduction, but can cause risks if it is moderate.
Neurologist Vivian Felisi explained in an interview in German Hospital Oswaldo Cruz CNNCoffee action Increased concentration It is widely connected to the caffeine, which is a substance that prevents the action of adenosine, neurotransmitter, which promotes relaxation and sleep.
“Preventing adenosine, increasing the release of other neurotransmitters such as caffeine dopamine and norepinephrine, which are associated with improvement, warning, mood,” he said.
“It is a reasonable consensus on scientific literature on severe caffeine cognitive effects, especially fatigue or sleep deprivation. It is important to remember that it improves continuous attention, reaction time and performance on repetitive tasks.
Accordingly, the effect should be between 30 minutes to 6 hours in the human body from the individual to the individual. “The maximum effect of caffeine occurs between 30 to 60 minutes, and its half life in the body may vary from 3 to 6 hours, depending on the person.”
Dangers and side effects of coffee consumption
Felisi warns about the dangers of unprecedented coffee consumption, such as insomnia, anxiety, irritability, tachycardia, tremors and gastrointestinal discomfort. She recommends it Daily dose of keifin Do not exceed the 400 mg mark, which corresponds to 4 cups of fried coffee.
“In some, small amounts are already triggering these symptoms,” he said. “To reduce these effects, it is important to respect personal tolerance restrictions and prevent exaggeration use. It can also help to distribute coffee throughout the morning and afternoon, preventing fasting or other exciting ingredients.”
The neurologist suggests that pregnant women are limited to 200 mg of caffeine intake. “It crosses the placenta and affects the embryo.”
Sleep disorders, generalized anxiety, cardiac arrhythmia or gastroesophageal reflux can also expand, whose symptoms can worsen with coffee consumption.
In addition, according to Felisi, caffeine develops resistance and its effect in some people decreases over time. In this case, the way out of the way is not only to increase the dose, but also to create a consumer strategy.
“Periodic breaks may be beneficial in the sensitivity of the body may not have a single positive effect on caffeine concentration,” he said.
