[A telemetric study of the secretoloytic effect of sea-air on children with bronchial asthma (author's transl)].

The problem was investigated whether persons with respiratory complaints would benefit from breathing the nebulized spray thrown up by the breaking of the waves on the shores of a North Sea island. The case material comprised 45 children (37 boys, 8 girls) who had suffered from bronchial asthma for an average of six years. The children were sent on a walk and their respiratory function was analyzed by means of telemetric equipment at 5 points: in the hospital, in a part in the centre of the island, at the beginning of their walk along the beach, 15 minutes later, and finally again at the hospital. A second group of children did the walk in the opposite direction. The greatest improvement in FEV1 was obtained after the 15-minutes' walk along the beach; this applied to cases with normal and with pathological FEV1 values. The results were significant. Prolonged stay at the beach increased the beneficial effects.
