The exhaustion caused by intense mental work can finally be explained. And is it an interesting scientific research that revealed that the brain can burn as many calories as if someone ran for half an hour?
According to Javier DeFelipe, professor-researcher at the Spanish National Research Council (CSIC), "The human brain accounts for about 2% of body weight and consumes 20% of the body's oxygen and glucose." For his part, Ignacio Morón, professor at the University of Granada and researcher at the Center for Research on Brain, Brain and Behavior (CIMCYC"The brain can consume about 350 calories in 24 hours – that's 20% of our daily expenses."
According to El País reports, the above does not mean that the individual will feel tired at the level of exercise, but he will burn about 350 calories for the simple act of thinking; However, it is important to point out that these data were derived from the anatomy of an adult with a medium-weight brain, about 1400 grams and about 70 pounds. .
DeFelipe went on to explain that while all daily activities require energy, "the brain is the most energy consuming organ" because it never stops its activity. , even at night.
"One hour of intense intellectual work consumes practically the same energy as an hour of intense physical work," and if the activity is prolonged and the stress increases, the brain spends even more energy, Morón adds.
The explanation for this process is that the brain devours pure glucose, a monosaccharide whose molecular formula is better known to function as a fuel for this organ and from which the ATP (adenosine triphosphate) necessary to perform all metabolic processes.
The question that arises at this stage is quite obvious: the study concludes while thinking slim? The answer, although it may sound obvious, is no. And there is a big difference between burning calories while thinking and losing weight while thinking. This last statement is of course false.
"Clearly, thinking about not losing weight, maybe thinking about walking vigorously or exercising," says Andrés Caetana, director of CIMCYC.
