![]() The sample size of Experiment 1 was determined using a power calculation based on a pilot study ( n = 8) on the Paired associate learning (PAL) task and based on a paired-sample t-test (G*Power Version 3.1.9.6). ![]() Additionally, the online screening ensured that they had not worn an eye mask for sleep before and they agreed not to nap on the days of the experiment. Participants agreed to abstain from alcohol and caffeine throughout the experiment. We selected participants who reported no hypersensitive skin or contact allergies and no problems falling asleep with open shutters and wearing both an eye mask and a wearable EEG device (Dreem headband, DH ). Methods ParticipantsĪll participants were healthy volunteers, with no history of drug/alcohol abuse, psychological, neurological, or sleep disorders. With this aim in mind, we ran a within-subject design to look at these cognitive processes (Experiment 1) and a follow-up study that examined sleep architecture (Experiment 2). Given the practical importance of these abilities in everyday life, for instance in studying at school or in driving a car, we wanted to examine the impact of eye mask manipulation of these abilities. Declarative learning and vigilant attention are both known to be sleep sensitive. In the current study, we set out to investigate the benefits of wearing an eye mask to block light during normal sleep in the home. Non-pharmacological methods for improving sleep are a topic of great current interest, and the use of an eye mask to prevent light from reaching the retina during overnight sleep has been demonstrated to positively affect self-reported sleep quality in intensive care units where patients are systematically exposed to high levels of light. assessing the link between light exposure and subsequent sleep, revealed that subjects with earlier exposure to light spent significantly more time in slow-wave sleep (SWS) at the expense of rapid-eye movement (REM) sleep. The tight interaction between light and sleep regulation is, therefore, clear, with a large body of evidence supporting the impact of light on sleep timing, macro-architecture, and duration. SCN activity is strongly synchronized by the light–dark cycle via intrinsically photosensitive retinal ganglion cells. In mammals, the sleep–wake cycle is regulated by the suprachiasmatic nuclei (SCN) of the anterior hypothalamus. ![]() Moreover, optimal academic performance is strongly related to the timing, quality, and quantity of sleep. Sleep quality and quantity are crucial for brain function, and studies have indicated that a night of sleep deprivation or multiple nights of partial sleep restriction have a negative impact on cognition, for instance, affecting subsequent memory encoding. Sleep plays an essential role in many physiological functions including immune control, energy conservation, homeostatic restoration, and memory processing. This suggests wearing an eye mask during sleep is an effective, economical, and noninvasive behavior that could benefit cognitive function and lead to measurable impacts on everyday life. Furthermore, the benefit to memory was predicted by time spent in slow-wave sleep while wearing the mask. We found that wearing a mask increased alertness and facilitated the encoding of novel information the next day. This study explored wearing an eye mask as a potential cognitive enhancer which protects overnight sleep by blocking ambient light. However, it can be disrupted by external stimuli such as light or sounds. Especially when you stumble onto that witchy orgy.Sleep is crucial for alertness and for preparing the human brain to encode new information. This is one dream you can't, and probably wouldn't, want to wake up from. And feel free to be as nosy (yep, you can open those drawers), uninhibited (you are encouraged to interact with the actors), and voyeuristic as you want. Be prepared to get lost the moment you put on the Venetian mask they give you at the entrance. There will be taxidermies, graves, candied confections, drawers filled with clues and tools, bloodied crime scenes, and, throughout them all, actors who will lure you into their own personal world of horrors and pleasures. Punchdrunk Theatre Company's latest immersive production " Sleep No More" is a weird mash-up of Shakespeare's Macbeth and Hitchcock brought to life in installations that are straight out of a '30s film noir set. But when the haunted house in question consists of a 100,000-square-foot hotel decked out in the finest antique shop ephemera, and staffed with free-roaming characters straight out of Macbeth, we're definitely lining up. We either A) wanted to get the hell out of there because we kept getting scared shitless by the spook with the bad makeup job, or B) the spooks with the bad makeup jobs (and even worse acting skills) just made us laugh. Getting lost in a haunted house when we were kids was never an enjoyable experience.
