Night owls — people who stay up late — have been shown to have an increased risk of depression. And now a new study says why that might be. Dusk dwellers tend to be less mindful — that is, less engaged in the present moment, researchers found. That, along with poor sleep quality and higher alcohol consumption, are likely explanations for their increased depression risk, researchers reported in the journal PLOS One. “Importantly, we considered the different facets of mindfulness as factors,” concluded the team led by senior researcher Simon Evans, a lecturer in neuroscience of the University of Surrey in the U.K. “Results pointed specifically to a protective role of the ‘acting with awareness’ facet,” in which people engage fully in the present moment and carry out actions with deliberate attention rather than on autopilot, researchers wrote. For the study, researchers surveyed nearly 550 university students using an online questionnaire. Students reported information on their sleep patterns, mindfulness, alcohol use and levels of depression and anxiety. The responses revealed that night owls were indeed more likely to report symptoms of depression compared to average sleepers, researchers report. Night owls also had worse sleep quality than average sleepers or morning birds, and they tended to consume more alcohol. These results jibe with earlier studies linking bad sleep and alcohol to depression, researchers noted. But this… read on > read on >
