The question of sleep insufficiency attempts to indicate healthy sleep more directly than with a measure of sleep duration, which may exclude important individual differences in sleep need. The preponderance of studies find that the sleep duration associated with lowest risk for adverse outcomes in adults is between 7–8 hours [12, 14–16]. Inter-individual differences in response to sleep deprivation have been demonstrated in controlled environments [17]. However, it has been challenging to capture differences in sleep need at the population level. The experimental studies suggest the pertinence of addressing the role of sleep sufficiency/insufficiency as a risk factor for cardiometabolic outcomes. Despite this, very few studies have specifically addressed health effects of unmet sleep need independent of sleep duration. Shankar and colleagues [18] explored the effects of perceived insufficient sleep on cardiometabolic disease. This study found a negative association between unmet sleep need and cardiometabolic health. Earlier studies also found a significant positive correlation between perceived sleep insufficiency and reported poor general health, functional deficits [1] and increased cortisol secretion and abnormal growth hormone metabolism
