A professor who has researched caffeine for many years says that energy drink producers are scientifically wrong to advertise their products as providing stamina and power.
Jack James, a professor of the psychology department at the University of Reykjavík, pointed out to Vísir that while many people could not imagine starting the day without their morning coffee, believing that it perks them up and gives them energy, “What is actually happening is it reduces caffeine withdrawal symptoms. A person does not feel themselves, and believes that caffeine can help them think more clearly and work better.”
He adds that “you can work just as well without coffee as with it. You don’t gain anything from it; it’s deceiving. It has an effect, but only because a person is experiencing caffeine withdrawal.”
These are among the findings James has discovered in research he has taken part in regarding the effects of caffeine on the human body. From this, he believes energy drink producers should amend the claims made about their products.
“That they give you extra energy or give you the ability to do things that you otherwise could not, this is just factually wrong,” he said.
