We examined polysomnography (PSG) and body temperature in a patient with delayed sleep phase syndrome who responded to phototherapy. The patient was a 31‐year‐old woman whose condition had slightly improved by a vitamin B 12 administration. Phototherapy was administered to her in combination with the vitamin B 12 medication, and this combined treatment successfully advanced her delayed sleep phase. On PSG, the regimen showed shortened sleep latency, decreased total sleep time and stages 1 and 2 sleep, and increased slow wave sleep. Phototherapy also improved temporal distribution of delta half‐waves (0.5‐2.0 Hz, 31 µV) as well as phase relationship between sleep and body temperature.
