The German Sleep Society (DGSM) is an interdisciplinary non-profit association with approximately 2.200 members being physicians specialized in pneumology, internal medicine, neurology, psychiatry, ENT medicine, otolaryngology, and pediatrics as well as scientists and researchers of psychology, physiology, biology, medical physicists, medical informatics, and other natural sciences. There is close cooperation with dentistry, orthodontics and oral and maxillofacial surgery.

The DGSM represents sleep research and sleep medicine in Germany as a member of the Association of Scientific Medical Societies in Germany (AWMF).

The aim of the DGSM is to promote research on sleep and its related fields, to improve the care of patients with sleep disorders and to arrange for the dissemination of new information on sleep research. The purpose of the statutes is accomplished in particular through scientific and practical activities of their members in the field of clinical and experimental sleep research, the care of patients reporting sleep complaints, and by the further education of all professional groups involved in this field. The purpose of the statutes is also realized by the organization of congresses, other scientific events, workshops, and lectures in the field of sleep research and sleep medicine and by the financing of further education and training.

The organs of the Society are the Board of Directors (“Vorstand”), the Scientific Committee (“Wissenschaftliches Komitee”) and the General Assembly (“Mitgliederversammlung”). The General Assembly establishes working groups dealing with different sleep medicine topics. Different working groups work together in networks on specific topics. The Board of Directors sets up commissions to implement defined tasks of the society, such as quality management or continuing education. The Scientific Committee is responsible for scientific congress preparation and the promotion of young scientists and advises the Board of Directors on scientific topics. The DGSM also offers proposals for qualification and advanced training for medical-technical personnel.

The scientific organ of the DGSM is the journal Somnologie. The Somnologie is also the scientific organ of the Austrian Society for Sleep Medicine & Sleep Research (ÖGSM) and the Swiss Society for Sleep Research, Sleep Medicine and Chronobiology (SGSSC).

The DGSM is in close cooperation with the European Sleep Research Society (ESRS) and the World Sleep Society (WSS).

The DGSM also works closely with sleep medicine self-help groups. In addition, the DGSM provides information for patients on sleep medical issues and information on DGSM-certified sleep centers.
