The analysis of sleep quality and its impact on sleepiness is a crucial aspect of human health. A wearable actigraphy that records accelerometry, ambient light, and body temperature was used to register the sleep habits of 41 healthy subjects for a minimum of 9 days. Afterwards, the subjects filled two questionnaires about the quality of sleep (Pittsburgh Sleep Quality Index - PSQI) and sleepiness (Epworth Sleepiness Scale - ESS) following the last day of the actigraphy. The subjects were divided into two groups based on a cut-off score PSQI ≥ 5 and several parameters obtained from actigraphy were compared between groups. Group 1 had better quality of sleep and less diurnal sleepiness than Group2. Nonparametric circadian rhythm parameters were compared between the groups and one parameter L5, was found to be the most relevant to identify the sleep conditions of the subjects.
