Prendersi una pausa da Facebook abbassa l'ormone dello stress. Lo ha scoperto uno studio australiano pubblicato dal Journal of Social Psychology.
I ricercatori dell'università del Queensland hanno reclutato 138 partecipanti, tutti utilizzatori abituali di Facebook. Metà dei soggetti, tra 18 e 40 anni, ha dovuto rinunciare al social per cinque giorni, mentre gli altri hanno fatto da gruppo di controllo continuando normalmente.
Nel primo gruppo al termine del periodo si è visto un calo dei livelli di cortisolo, ormone associato allo stress, che invece è rimasto invariato negli altri. "Anche se i partecipanti allo studio hanno mostrato un miglioramento nello stress fisiologico - spiega però Eric Vanman, l'autore principale - hanno anche riferito un minore senso di benessere, dichiarando di non vedere l'ora di tornare a usare il social network. Questo studio comunque ci dice che uno stop di pochi giorni nell'uso di Facebook può migliorare lo stress, almeno a breve termine".
