Abstract
Network communication is now the most familiar communication tool for people, at least in the business world and the schoolyard. Despite its convenience, people sometimes worry about the media and devices which automatically receive messages. Some people have found that such network communication media are sometimes addictive, resulting in an adverse influence on performance of the students and employees. Then, some organisations, such as schools and companies, banned using or carrying these devices. However, the effect of network communication is not only to encourage excessive use but also having a stressful influence on users. This paper shows the circumstances causing such stress and proposes "network leave," during which one is away from network communication and one's familiar people know one cannot respond to incoming messages.
