Teresa Belta and Esther Priyadharshini, from the University of East Anglia (UK), have shown that being always busy, especially during childhood, prevents the development of the imagination . On the contrary, being bored and doing nothing is positive for the brain. While we contemplate the shrews and remain unoccupied, neural circuits are activated that form the so-called "default network", discovered in 2011 by Raichel and Shculman. Apparently this network is the one that makes us daydream, is concerned with connecting experiences and lessons learned in the past with future plans, creates narratives about our own lives chaining memories and gives wings to the imagination. Not surprisingly, between 60 and 80% of the brain's energy is dedicated "only" to maintaining the connection between neurons .
By the way, we must bear in mind that if we spontaneously yawn it is not out of boredom , nor is it because of hunger, as is often thought. As a study by Princeton University (USA) has shown, it is most likely that we have the "brain" too hot, since at a biological level, yawning is a mechanism that serves to cool the brain.
