About this Issue

Tiffany Chin created the dreamy Tarot card-inspired illustrations for “Up All Night,” a story that pulls back the curtain on disrupted slumber. The Toronto-based artist says she is most productive “at the crack of dawn” and is asleep long before the late-night talk shows go to air. 

In “On the Clock,” Megan Mueller delves into the factors that influence our circadian rhythms. By day, the long-time research writer manages communications for U of T’s Hart House. By night, Mueller confesses to keeping irregular hours. She reads late into the evening, but rises early to fill her cat’s empty food dish.

For the past decade, award-winning health reporter and news editor Lauren Vogel has investigated the health issues that keep doctors up at night for CMAJ. In “Up All Night,” she unravels the mysteries of why we sleep and what happens when we can’t — a topic she knows all too well. The writer, who likes to start her workday at 4 a.m., says she has “forged an uneasy peace” with her sleep paralysis demons.
