Abstract: The aim of this study was to verify whether polysomnography represents a stressful situation by assessing cortisol levels and the sleep pattern of healthy community-living elderly admitted to a sleep disorder center (SDC). Subjects slept for two sequential nights at the SDC for polysomnographic recordings. Blood was sampled at 0800 h, 1600 h, and 2300 h and 24-h urine was collected for cortisol determination. Three months later, subjects were visited at home for blood and urinary collections. Cortisol levels were higher in the SDC than at home at 0800 h but were lower at 2300 h and similar at 1600 h. No differences were observed in urinary cortisol. Polysomnographic recordings indicated a poorer sleep pattern in the first night. Our data indicate that a short-term stay of healthy elderly in a SDC disrupts sleep pattern in the first of 2 nights, without representing a stressful experience, as evaluated by cortisol levels.
