The Internet and, in particular, social networks are an increasingly important part of daily life for both adolescents and adults who maintain a virtual relationship with others sharing interests and goals. Very often, they disclose more about themselves online than they do in person. However, cyberbullying and cyberostracism can be problematic for adolescents and sensitive individuals, who might be negatively affected by social networks. Some studies have shown an increased risk of depression, whereas others suggest beneficial effects through enhanced communication, social connection, and self-esteem.
Bronchial asthma is an increasingly frequent disease in the industrialized world, and psychological implications play a role in increasing or in reducing its severity.
One year after the case report of an asthma exacerbation that may have been triggered by Facebook, it seems reasonable to analyze the effects of social networks on bronchial asthma.
