This week, we’re excited to announce the launch of Arcashift, our new and improved mobile app for shift workers to sleep and feel better. With the early access program of our first app, Shift, we learned about essential features that shift workers need to better manage their days. Arcashift is the distillation of our learnings, […]
Chronomedicine and Immunity: How Circadian Rhythms Impact Our Bodies’ Immune Systems
Cold and flu season are starting in the southern hemisphere, while allergy season is in full swing in the global north. Both of these are linked to our immune systems, which are built out of many different organs, hormones, and free-roaming, invader-killing cells such as T-cells. Because infection can happen anywhere, our immune systems interact […]
What we talk about when we talk about chronomedicine
I was reading this article on circadian variation in immune response a couple of weeks ago when I came across this quote, seemingly engineered in a lab to get my adrenaline pumping: “McKeating [says] that when she thinks back to the long line of failed vaccines in this field, she wonders whether timing may have […]
What is circadian sleep sufficiency?
Here’s a weird thing about shift workers: Their sleep duration doesn’t always predict how sleepy they feel. Which is weird because… shouldn’t it? After all, somebody who sleeps for a longer period of time should feel less sleepy than someone who sleeps only for a short period of time, right? This paradox isn’t actually that […]
Interview with Dr. Gena Glickman
Could you tell us a little bit about yourself and your research? I’m an Assistant Professor in the Departments of Psychiatry and Neuroscience at Uniformed Services University of the Health Sciences as well as Director of the Chronobiology, Light, and Sleep Lab in Bethesda, Maryland. Immediately prior to arriving at USUHS, I was in San […]
Interview with Dr. Hrayr Attarian
Thanks for joining me today. You have such an impressive resume. Would you mind telling me about yourself and how you got into sleep medicine? While studying for my undergraduate in biology, I took a class in abnormal psychology, and one of the lectures was about dreams, which piqued my interest in psychology and sleep […]
The Dark Side of Daylight Saving Time
Welp, here we are yet again. We are once more setting our clocks forward one hour to have more evening light. Why? That’s a good question. The history of Daylight Saving Time (DST) is complex and goes back to 1918 (in the United States). But lately more and more people are asking if it’s even […]
The way you think about sleep is wrong
“I didn’t get nearly enough sleep last night.” “I need to get to bed sooner.” “I just can’t wake up in the morning, and I’m not a morning person.” We often think of sleep as a debt to be paid to some mysterious collector. Sleep evades us when we most want it and won’t let […]
The health benefits of darkness
Our apps tell you when to avoid light because light exposure is the number one input to your body’s circadian clock (which regulates sleep, metabolism, immune response, DNA repair, physical performance and more). Light at some times speeds up your clock and helps you fall asleep faster, while light at other times can slow down […]
What really helps you go to sleep
Don’t use your phone before bed! Turn off overhead lights in the evening! Block blue light as you wind down! There are tons of recommendations out there for helping you get to sleep at night that deal with light and technology, and—spoiler alert—I think they’re right on the money. But missing from the standard advice […]
