The effects of sleep deprivation and quality of sleep on cognitive performance and mental wellbeing
Studies in the field of sleep have shown that sleep deprivation can affect mental wellbeing and furthermore that sleep is necessary for cognitive abilities. Few studies have examined the effect from both sleep duration and quality of sleep so the purpose of this study was to analyze the impact from...
