Più si usa Facebook, meno si è felici e in salute. Non è la prima volta che i social network finiscono nel mirino di ricerche scientifiche. Questa volta la tesi è sviluppata in uno studio condotto dall'Università di Yale e della California e rilanciato dal Wall Street Journal.
"Le interazioni faccia a faccia migliorano il benessere. Con l'ubiquità dei social media sono emerse importanti questioni sull'impatto delle relazioni - dicono i ricercatori -. Abbiamo esaminato le associazioni che ci sono tra l'attività su Facebook e lo stato di salute fisica, mentale e la soddisfazione di vita. I risultati hanno dimostrato che in generale, l'utilizzo della piattaforma non è associato al benessere".
Ad esempio, sottolinea la ricerca, se alla pubblicazione di un post non corrisponde un numero di "mi piace" giudicato sufficiente c'è un peggioramento del 5-8% dello stato fisico e mentale.
I ricercatori hanno monitorato 5'208 adulti, accedendo direttamente alle loro attività su Facebook per due anni, tra il 2013 e il 2015.
