According to a new study, Web browsing can actually refresh tired workers and enhance their productivity, compared to other activities such as making personal calls, texts or emails, let alone working straight through with no rest at all. 

The study, "Impact of Cyberloafing on Psychological Engagement," by Don J.Q. Chen and Vivien K.G Lim of the National University of Singapore, was presented last week in San Antonio, Texas, at the annual meeting of the Academy of Management, an association of management scholars.
