Homeostatic Regulation of Sleep in Short Sleepers

This single-center study targets adults with distinct sleep profiles, divided into three categories: natural short sleepers, characterized by a reduced nocturnal sleep duration; subjects with idiopathic hypersomnia (IH) followed at the Sleep Disorders Unit of CHU Gui de Chauliac, with excessive daytime sleepiness; and control normal sleepers, with standard sleep duration and no specific complaints. The aim of this study is to analyze the mechanisms of slow-wave regulation during sleep according to sleep phenotype (normal, short, and long sleepers/idiopathic hypersomnia) by examining the decay of EEG spectral power in the delta band over central regions during the first night of continuous 32-hour recording.
