Let’s face it: for some of us, sleep is hard. Whether you’re pulling night shifts, catching flights across time zones, or just trying to figure out why your 3 p.m. coffee is ruining your 10 p.m. bedtime, staying in sync with your body can feel like an uphill battle. That’s where Arcashift comes in. We […]
Join the July Challenge in Arcashift Our beloved circadian mascot, Sol, has lost his groove. He’s been staying up too late, skipping morning light, and basically ignoring everything he knows about good circadian hygiene. (Relatable, right?)

Ever wonder if sleeping less actually makes you more likely to get sick? The answer is: absolutely. In one study, researchers tracked people’s sleep for two weeks, then exposed them to the common cold virus (yes, really).

Have you ever timed up your steps with a friend’s as you walk on the sidewalk? Or synced up your steps to match a pattern of tiles on the ground? Our bodies know what it’s like to find a groove, a pattern, a rhythm. It turns out, that’s not just true for your feet—it’s also […]
You fall asleep just fine… but then suddenly you’re wide awake at 3:00 AM, staring at the ceiling. Sound familiar? If this happens often, your internal clock, or circadian rhythms, might be playing a bigger role than you think. Let’s break it down with an analogy.
