One can finally explain the exhaustion caused by intense mental work. And it is that interesting scientific research has revealed that the brain can burn itself as many calories as if someone was running for half an hour.
According to Javier DeFelipe, professor-researcher at the Higher Council for Scientific Research ( CSIC .]), "The human brain represents about 2% of the body weight and consumes 20% of the oxygen and body glucose ". For his part, Ignacio Morón, professor at the University of Granada and researcher at the Center for Research on the Mind, Brain and Behavior ( CIMCYC ), "the brain can consume 350 calories in 24 hours.This corresponds to 20% of our daily expenses. "
According to reports from El País, the foregoing does not mean that the individual will feel tired at the level of health. exercise, but it will burn about 350 calories by just thinking; However, it is important to point out that these data were based on the anatomy of an adult whose brain weighs about 1400 grams and about 70 kg.
DeFelipe also explained that even though all daily activities require energy, "The brain is the organ that consumes the most energy" because it never stops sounding. activity, not 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 stress increases, the brain spends even more time. energy, adds Morón.
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 the metabolic processes.
The question that arises at this point is quite obvious: does the study conclude that thinking thin? The answer, although it may sound obvious, is no. And there is a big difference between burning calories while thinking and losing weight thinking. Of course, this last statement is false.
"Thinking clearly does not lose weight, maybe think about walking vigorously or exercising," says Andrés Caetana, director of CIMCYC .
