SLOWAVE – An Exploration on Sleep + Society

Our anxiety about sleep underscores some uncomfortable realities about the present. How is it that an essential biological function has had to fight so hard to be recognized as, well, essential? When we look back on our lives, the third we spend recharging registers as an opportunity cost, something to be overcome. But what if the on/off binary that we understand consciousness through was the wrong lens to use on sleep? Can we reject the awake/asleep binary, and plot sleeping and dreaming on an expanded spectrum of consciousness? Sleep isn’t death–it’s something else entirely. The future of sleep won’t be its absence, it will be a new class of people leveraging its creative potential. Slowave is the response to this realization


Comparing the Effects of Nocturnal Sleep and Daytime Napping on Declarative Memory Consolidation

Nocturnal sleep and daytime napping facilitate memory consolidation for semantically related and unrelated word pairs. We contrasted forgetting of both kinds of materials across a 12-hour interval involving either nocturnal sleep or daytime wakefulness (experiment 1) and a 2-hour interval involving either daytime napping or wakefulness (experiment 2). Beneficial effects of post-learning nocturnal sleep and daytime napping were greater for unrelated word pairs (Cohen’s d = 0.71 and 0.68) than for related ones (Cohen’s d = 0.58 and 0.15). While the size of nocturnal sleep and daytime napping effects was similar for unrelated word pairs, for related pairs, the effect of nocturnal sleep was more prominent. Together, these findings suggest that sleep preferentially facilitates offline memory processing of materials that are more susceptible to forgetting.

Your Body’s Best Time for Everything

Surprisingly, fatigue may boost creative powers. For most adults, problems that require open-ended thinking are often best tackled in the evening when they are tired, according to a 2011 study in the journal Thinking & Reasoning. When 428 students were asked to solve a series of two types of problems, requiring either analytical or novel thinking, their performance on the second type was best at non-peak times of day when they were tired, according to the study led by Mareike Wieth, an assistant professor of psychological sciences at Albion College in Michigan. (Their performance on analytical problems didn’t change over the course of the day.) Fatigue, Dr. Wieth says, may allow the mind to wander more freely to explore alternative solutions.
