Se ci si vuole prendere una pausa rigenerante da un lavoro impegnativo è meglio evitare di usare il break per dare una sbirciatina allo smartphone.
Lo afferma uno studio della Rutgers University pubblicato dal Journal of Behavioral Addictions, secondo cui l'uso del telefonino impedisce al cervello di ricaricarsi.
I ricercatori hanno chiesto a 414 studenti universitari di risolvere una serie di 20 crucipuzzle. A metà dell'esercizio alcuni hanno fatto una pausa durante la quale era permesso usare il cellulare, altri invece avevano a disposizione solo carta o un computer mentre un gruppo non ha fatto pause.
E i partecipanti che hanno usato lo smartphone hanno impiegato dopo la pausa il 19% in più di tempo per risolvere gli esercizi, trovando il 22% in meno di parole, una prestazione solo leggermente migliore rispetto a chi non aveva avuto il break.
