[Suicide and the weather. Risk of suicide in mental disorders and possibilities for prevention].

The risk of suicid in psychic disorders and possibilities of suicid prophylaxis The mysterious connection between weather and suicidal acts has been of particular interest at all times. In the past years extensive studies were carried out. But often the results were differing from each other. Nowadays, every person, committing suicid is regarded as psychically disturbed. Therefore, it may be better to analyse the diagnoses retrospectively and to determine which type of psychiatric illness is reacting significantly to which meteorological event. The results of this study using the "coincidence method" (n = 17 268) make it possible to give exact clues, which meteorological event may be dangerous to which kind of psychiatric illness. The time before a change of weather is of importance. The daily medical-meteorological telephone-service in the Federal Republic of Germany (bioprog) is therefore a biometeorological contribution to the prophylaxis of suicides.
