In the first, 138 participants were assessed across two nights and two subsequent days, sleeping as they chose (Fig. Two online phases of the study were conducted through Amazon Mechanical Turk (MTurk). Finally, we examine whether this effect is bi-directional, such that people blind to the experimental context nevertheless rate sleep-deprived individuals as being lonelier and less desirable to socially engage with. We further test the prediction that such a profile of social separation is instigated by hypersensitivity of brain networks that warn of human approach, yet a converse reduction in activity within prosocial networks associated with the comprehension of another’s intentions. Moreover, we examine whether the relationship between sleep loss and loneliness is observed following very modest reductions in sleep quality, from one night to the next, in a micro-longitudinal study. Here, we test the hypothesis that a lack of sleep leads individuals to enforce greater social separation from others. Finally, whether this effect is bi-directional, such that others in society reciprocally perceive sleep-deprived individuals as lonelier, even less desirable to interact with, is similarly unknown. In humans, intrapersonal distress and self-reported loneliness are linked to worse sleep quality 16, specifically lower sleep efficiency 7, 17, 18, while active socializing is associated with better sleep quality 19.Īlthough social isolation can result in sleep impairment, it remains unknown, in human or non-human species, whether the opposite is true: does sleep loss lead individuals to feel lonely, become less social, and enforce greater social separation from others? Moreover, the underlying neural mechanisms associated with such an asocial phenotype remain unexplored. In rodents, social isolation impairs subsequent sleep quality and efficiency 15. Though numerous factors are associated with social isolation and withdrawal from inter-personal interactions, recent evidence suggests that insufficient sleep may be one such candidate. The broad concept of an asocial phenotype therefore involves multiple features, including social distancing and withdrawal from others 10, subjective feelings of social isolation and loneliness, and others socially avoiding you 11, 12, 13, 14. If an individual is perceived as lonely, others will frequently disengage from interacting with them 9, resulting in a compounding cycle of social isolation. Importantly, loneliness has a self-reinforcing characteristic. Individuals who feel socially isolated and alone also have higher rates of cardiovascular disease, alcoholism and suicidality 1, physical diseases related to stress and compromised immune function 7, and in later life, greater risk of degenerative dementia 8. Conversely, social isolation and loneliness are known risk factors for premature death 4, 5, more so than being obese 6. Sociality plays a fundamental part in the wellbeing of Homo sapiens 2, 3, 4. Human beings did not evolve to be alone 1.
