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 […]
Official Company Stance on Permanent DST
NOOOOOO!!!! Noooooooooooooooooooooooo!!!!!! (To hear our actual stance on permanent DST, check out this blog post. Short version: we love getting rid of the seasonal time change, as long as we end up on permanent standard time, not permanent DST.)
Interview with Dr. Louise O’Brien
Thanks for letting us interview you, Dr. O’Brien. Would you mind introducing yourself to our audience—where do you work, what do you do? I’m Louise O’Brien, an Associate Professor at the Division of Sleep Medicine, Department of Neurology, at the University of Michigan. My work focuses mostly on sleep disruption in pregnant women and its […]
Naps, part one.
The first thing I want to say about naps is that I’m almost always for them. Naps can help you recover from sleep deprivation. Naps are good. But let’s talk about that almost always. When might you want to avoid napping? Well, maybe you’re trying to shift your personal time zone and are at a […]
Book of the Month (January)
The Circadian Code by Satchin Panda In keeping with the theme of new beginnings, this January we introduced a book of the month. Join us as we work our way through books that highlight the importance of circadian and sleep health 😴 Up first: The Circadian Code by Satchin Panda of the Salk Institute for […]
Interview with Dr. Cathy Goldstein
We sat down to talk with Dr. Goldstein on what she sees as the future of wearables in the sleep clinic. Enjoy! Thank you for taking the time to meet with me today! Could you take a minute to introduce yourself and say a little about what your job is? Cathy Goldstein, MD. I’m a […]
Tis the Season: Seasonal Effects and Circadian Rhythms
As today is the shortest day of the year in the Northern Hemisphere (and the longest in the Southern Hemisphere), it seems appropriate to talk about how the seasons change our bodies’ rhythms. Many things change with the seasons, but the main seasonal variation that I will consider here is the variation in day length. […]
Take a Break (From Social Jet Lag)
Why do you go to sleep when you do? Sure, there’s a big part of it that’s physical: You go to sleep because you’re sleepy. But you might also stay awake, even when you’re on the verge of collapsing from fatigue, because you have work to get done. Or because your neighbor is practicing a […]
Circadian Science Says: Go Outside This Thanksgiving for Better Sleep and Energy
Here’s a fun fact: You probably get way less light exposure during a normal work day than you would if you were out camping. “Sure,” you say. “That’s no surprise. At home, I have walls around me to block the sun. If I’m camping, I presumably have fewer walls.” “You don’t understand,” I say, leaning […]
inTRO to ipRGCs ( Intrinsically Photosensitive Retinal Ganglion Cells)
Rods, cones, and…ipRGCs? For almost a century and a half, it was believed that the mammalian retina only had two types of photoreceptors, rods and cones. That assumption was not proven to be false until some studies in the late 1990s proved the existence of a third kind mammalian photoreceptor that differed greatly from rods […]
