New research seeks to understand whether the effects of coffee is dependent on caffeine or if it's the experience of drinking coffee that matters.
For many people, the day doesn’t start until their coffee mug is empty. Coffee is often thought to make you feel more alert, so people drink it to wake themselves up and improve their efficiency. Portuguese scientists studied coffee-drinkers to understand whether that wakefulness effect is dependent on the properties of caffeine, or whether it’s about the experience of drinking coffee.
“Taking into account that some of the effects that we found were reproduced by caffeine, we could expect other caffeinated drinks to share some of the effects,” added Picó-Pérez. “However, others were specific for coffee drinking, driven by factors such as the particular smell and taste of the drink, or the psychological expectation associated with consuming that drink.
“The changes in connectivity were studied during a resting-state sequence. Any association with psychological and cognitive processes is interpreted based on the common function ascribed to the regions and networks found, but it was not directly tested,” cautioned Sousa. “Moreover, there could be individual differences in the metabolism of caffeine among participants that would be interesting to explore in the future.
