The impact of five nights of sleep restriction on emotional reactivity
An inadequate amount of sleep can negatively affect emotional processing, causing behavioural and neurofunctional changes. However, unlike the condition of total sleep deprivation, which has been extensively studied, the effects of prolonged sleep restriction have received less attention. In this study, we evaluated, for the first time, the effects of five nights of sleep restriction (5 hr a night) on emotional reactivity in healthy subjects.Forty-two subjects were selected to participate, over two consecutive weeks, in two experimental conditions in counterbalanced order.
