A Guide to Non-Photic Zeitgebers We can all agree that the difference between night and day is, well, night and day when it comes to light. The progressive change in light present in our environment is subconsciously tracked by our bodies and that information is used to help time our sleep-wake cycles. Of course, not […]
Light at night is bad, people.
Imagine you’re on a swing on a playground with a friend standing behind you. This friend is not a jerk, so they’re going to push you when a normal person would push you on a swing—right when you’re at the end of your backwards motion and ready to start moving forward again. They, like a […]
We Rate Sleep Memes, Pt. 2
Back by popular demand, here is part two of the “We Rate Sleep Memes” blog series. If you’re just now tuning in (check out part one here), the title pretty much says it all. We take sleep-related memes we find online, we use them as an excuse to talk about sleep and circadian science, and […]
What do shift workers do & what might they do?
So you want to help shift workers feel better—sleep better, be safer, have fewer of the long term chronic health problems that go hand in hand with shift work. How do you do it? Where do you start? As some of the most circadian-wrecked people around, shift workers have been the topic of no small […]
One Simple* Rule for Understanding Your Sleep
My friend sent this to me the other day: “If I go to bed at 10:30 pm, I often wake up at 4:30 or 5:30 am and can’t go back to sleep. But if I go to bed at 1:00 am, I fall asleep easily and can sleep until 9:00 am. Throughout the work week […]
A Space for Shift Workers
We’ve noticed a lot of shift worker communities online. I’m not talking about just a few here—I’m talking about hundreds. These communities also each tend to have thousands of active followers. Surprising, right? Until you remember that over 30 million people in the U.S. currently live with shift work. From Instagram accounts to Twitter hashtags, […]

Could you introduce yourself and tell us a little bit about what you work on? I’m the Director of Clinical Sleep Science at Cerebra. We’re a sleep technology company focused on better diagnosis and treatment […]
Visualizing MESA, pt. 1
One of the things we’re interested in as scientists is what longitudinal, large-scale data collection can tell us about sleep. Along those lines, one of our research projects involves looking at how models of circadian rhythms, as well as different sleep regularity metrics, can help us understand different outcomes for different folks. And as part […]
Book Of The Month (March)
When by Daniel H. Pink Another month, another Book of the Month! Starting with its title, When by Daniel Pink hones in on just how simple the idea of timing things better really is. The question of “when” is in the same fundamental category as where, why, how, and what. Yet, as Pink notes: “We […]
Scientific Tests
Algorithms are really easy to mess up. Take your pick for how: overfitting to training data, having bad training data, having too little training data, encoding human bias from your training data in the model and calling it “objective”. Feeding in new data that’s in the wrong format. Typos, subtle typos, nightmarishly subtle typos. Your […]
