SLEEP GROOVE isn’t just another sleep book. Written by Olivia Walch, Arcascope’s CEO, it offers readers an accessible and entertaining tour of the complexities of circadian rhythms and sleep. The book breaks down advanced concepts with easy-to-understand explanations, using humorous analogies, eye-catching illustrations, and comics to guide readers through the often misunderstood machinery of their […]
Did you know that during a typical workday, you get far less light exposure than you would outdoors? That’s because indoor lighting is no match for the brightness of natural sunlight, and this difference has a big impact on your body’s internal clock (aka your circadian rhythms). This matters because your circadian rhythms rely on […]
Let’s say I want to boost circadian amplitude as much as I can. What light/dark schedule should I put myself on? This is a very tough question to answer experimentally, given how many possible light/dark schedules there are (infinite) and how expensive experiments like this can be (near infinite). But mathematical modeling can give us […]
The end of Daylight Saving Time (DST) is the good one of the two time changes, since we gain the opportunity for an extra hour of sleep instead of losing one. But before you set your clocks back and enjoy that extra rest, it’s important to understand how sudden changes can disrupt your daily routine. […]
“If you want to become an earlier chronotype, get more zeitgeber during your phase advance region and less zeitgeber during your phase delay region.” My head is in my hands. At parties, if no one stops me, I will often rant about math’s UI/UX problem. Listen, I say. We just casually drop that sin-1(x) is […]
The nap planner scores naps based on the following: with more dimensions to come. How do we estimate these things? We run hundreds of simulations of how your body’s clock is shaped by your activity patterns in the normal course of running Arcashift. The nap scores are natural extensions of these simulations, taking on the […]
If you’ve ever thought a nap might be the key to boosting your energy, we’ve got great news! Introducing Arcashift’s new Nap Planner—an innovative, circadian-driven tool that understands your body’s internal clock. How does it work? The Nap Planner takes the guesswork out of napping by analyzing your body’s internal clock and recommending the best […]
Like anyone talking about anything, I tune my content to the audience. When I talk about our tech to travelers, I tell them our apps can help them get over jet lag faster. When I talk about our tech to shift workers, I highlight how we can help them sleep more and get them to […]
Remember awhile back when we published ‘Light at Night is Bad, People‘? Well, consider this the reunion tour—today, we’re diving back in to explore why nighttime light is the ultimate sleep stealer. Picture this: it’s bedtime, and you’re ready to fall fast asleep. Then, bam! You remember a work email and crack the laptop open. […]
Night shift friends: Ever wake up and find yourself unable to fall back asleep, even though you know you’re tired? Or find yourself unable to fall asleep in the first place, even though you’ve been awake for 20 hours? Blame it on your circadian rhythms. Yup, those internal body clocks that tell you when it’s […]
