Polysomnography (PSG) and body temperature were examined in a patient with non‐24 h sleep–wake syndrome who responded to phototherapy. The patient was a 17‐year‐old male who had been suffering from a free‐running sleep–wake rhythm for 2 months. Phototherapy was administered to the patient while he was admitted to our hospital. This treatment immediately changed the free‐running sleep–wake and body temperature rhythm of the patient to the environmental 24‐h rhythm. On a polysomnography, total sleep time and stages 1 and 2 and REM sleep were decreased, and percentage stage 3 + 4 was increased by phototherapy. The time of minimum body temperature (mBT) was located at the latter half of the sleep phase through the clinical course of the patient.
