My New Year’s (Circadian) Resolution

Although circadian rhythms are being recognized more and more for their relevance to jet lag, shift work, the grogginess people feel after daylight saving time transitions, and health and medicine at large, it’s still a long way behind sleep in entering popular discourse. People know “8 hours a night,” but they don’t know “align your […]

How to beat jet lag

Ah travel—booking tickets, hopping on a plane, immersing yourself in a new locale, and…feeling more tired than you’ve ever felt before. Jet lag is our name for all of the circadian disruption—and subsequent fatigue—that comes from traveling and changing time zones. While we can’t help with the physical toll being in an airplane seat for […]

The Future of Circadian Rhythms in Healthcare (It’s more than just sleep!)

Sleep is heavily influenced by your circadian rhythms, but it’s not the only function in your body that falls into that category. In fact, circadian rhythms govern almost every process our body carries out over the day, including metabolism, immune response, DNA repair, and physical performance. One topic that’s been getting a lot of buzz […]

Circadian science Shift Work

Running the numbers on health care shift workers

At Arcascope, we’re focused on helping shift workers get more sleep and feel better with circadian-specific interventions. In particular, we’ve spoken to a lot of shift workers in the healthcare industry about their experiences working nights.  A lot of the lessons we’ve learned are echoed in this recent survey we ran with 218 nurses who […]

Circadian science Shift Work

Feeling Flat

Over and over again, I’ve heard shift workers say something like the following:  “I have no rhythms.”  “It’s just a constant experience of bleh.” “I get off shift, and more than tired, I just feel… flat.” “Ah,” I think when I hear this. “The amplitudes of their circadian rhythms have been squashed.” To steal an […]
