Poor sleep can literally kill your social life.
UC Berkeley researchers have found that sleep-deprived people feel lonelier and less inclined to engage with others, avoiding close contact in much the same way as people with social anxiety.
Worse still, that alienating vibe makes sleep-deprived individuals more socially unattractive to others. Moreover, even well-rested people feel lonely after just a brief encounter with a sleep-deprived person, triggering a viral contagion of social isolation.
The findings, published today in the journal Nature Communications, are the first to show a two-way relationship between sleep loss and becoming socially isolated, shedding new light on a global loneliness epidemic.
“We humans are a social species. Yet sleep deprivation can turn us into social lepers,” said study senior author Matthew Walker, a UC Berkeley professor of psychology and neuroscience.
Notably, researchers found that brain scans of sleep-deprived people as they viewed video clips of strangers walking toward them showed powerful social repulsion activity in neural networks that are typically activated when humans feel their personal space is being invaded. Sleep loss also blunted activity in brain regions that normally encourage social engagement.
