Chronomedicine and Immunity: How Circadian Rhythms Impact Our Bodies’ Immune Systems

Chronomedicine, Circadian science / By Eric Canton

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

Chronomedicine / By Olivia Walch

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?

Circadian science, Shift work, Sleeping troubles / By Olivia Walch

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 …

Circadian science, Interviews, Sleeping troubles / By Roque Mesa

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

Circadian science, Lighting, Sleeping troubles / By Tamara Brady

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

Circadian science, Sleeping troubles / By Kristina Ng

“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

Circadian science, Lighting, Sleeping troubles / By Kristina Ng

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 …
