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 […]
This blog is the spiritual sequel to our last blog post on ways of measuring sleep regularity. Unlike the last one, though, which was based on an excellent review article, this post is Olivia’s off-the-cuff (and extremely wonkish) thoughts on the topic of circadian amplitude. There’s a reason for a lack of formality, though, which […]
Recall, if you will, that elementary school classic, “Guess How Many Beans Are In The Jar.” Over the years, I’ve guessed at many beans in many jars, but none sticks with me like the first: Halloween, 1998. I was dressed as the Mona Lisa. The jar was filled with jelly beans. I counted all the […]
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 […]
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. […]
Are you navigating long hours outside the traditional 9-5 schedule? Whether you’re a nurse, firefighter, or factory worker, you’re probably familiar with the challenges of irregular shifts. But have you heard of Shift Work Disorder (SWD)? Shift Work Disorder is, well, exactly what it sounds like. It’s a condition that disrupts your body’s natural sleep-wake […]
