For many people, the day doesn’t start until they’ve had a cup of espresso.
It is the drink that most people use to wake up, feel extra alert and improve their performance.
But that all-important morning espresso can act as a placebo in response to one test.
Portuguese scientists studied espresso drinkers to understand whether this wakefulness effect depends on the properties of caffeine or is related to the experience of espresso consumption.
They recruited people who drank at least one cup of espresso a day and took two quick MRI scans — one before the espresso or after consuming the espresso or consuming sparkling water with an identical amount of caffeine in it.

Brain scan analysis revealed that default mode community connectivity associated with self-monitoring and self-reflection processes decreased after each espresso and caffeine intake.
This means that everyone told people to additionally prepare for the performance of duties from rest mode to work mode.
But espresso consumption increased connectivity in the wider visible community and relevant government leadership community—mind components associated with working recollection, cognitive management, and goal-directed habits.
This did not occur when members recently drank caffeinated water.
In different phrases, the researchers mentioned that if you want to not only feel alert, but also be able to go, caffeine alone is not enough – this cup of espresso needs to be explored.
The first creator Dr. Maria Picó-Pérez from Jaume I University mentioned: “In short, subjects were more ready for action and more alert to external stimuli after drinking coffee.
“Given that some of the effects we found were replicated by caffeine, we might expect other caffeinated beverages to share some of the effects.”
“However, others were specific to coffee drinking, driven by factors such as the specific aroma and style of the beverage or the psychological expectations associated with drinking the beverage.”
The authors found that it was possible that knowledge of decaffeinated espresso could lead to these benefits, but their test could not support this.
The results were published in the journal Frontiers in Behavioral Neuroscience.
A separate analysis published earlier this year confirmed that people slept worse on days after drinking espresso, yet walked more.
When people can drink as much espresso as they want, they take about 1,000 extra steps each day, according to a study published in the New England Journal of Medicine.
However, on days when identical people imposed abstinence, they slept about half an hour longer.
