Although allergic rhinitis is not considered as a severe disease, its impact is substantial on patients' quality of life, psychological condition, and professional life or life at school. These consequences - including the need for regular medication - have only been taken into account in the last few years.
Allergic rhinitis entails adverse physical, psychological and social consequences for affected individuals.
In children[1] and adolescents, [2] school performance and extracurricular activities are diminished. In the case of chronic rhinitis, learning difficulties are noted.
Adults[3] report reduced concentration and productivity.
According to the ERAP study[4] on perennial rhinitis:
The ERASM study[5] on seasonal rhinitis showed that mood and sleep patterns were adversely affected in more than 70% of patients during the pollen season.
The same problems were pointed up in the ECRIN study, in which approximately 40% of patients reported rhinitis related insomnia as well as reduced physical activity and levels.
The recent CREDES* survey showed that the quality of life of asthmatics is significantly affected by the disease.
The clinical symptoms of asthma are poorly controlled in one out of six cases, mainly in severe persistent disease.
