Circadian Rhythm, Chronotypes & the Science of Sleep | Jenna Gearey on The Deets with Duddy

Jenna Gearey is a researcher at the University of Calgary studying circadian rhythm and sleep science—and yes, she’s also Duddy’s sister.In this episode of The Deets with Duddy, we dig into what your body’s internal clock is really doing—and how things like shift work, screentime, and caffeine throw it off. We talk about:Why staying up past midnight isn’t just “bad sleep”—it’s a biological mismatchWhat your chronotype is and how it affects your energy and focusWhether melatonin, blue light glasses, and sleep apps actually do anythingHow to function when your rhythm doesn't match your scheduleWhy your rhythm isn’t broken—you just might not be on the same wavelength as the world around youPlus: how light regulates your brain, why sleep is only part of the circadian story, and how mice helped reveal what chronic circadian disruption does to your heart and blood sugar.🧠 Read Jenna’s published research:“Chronic circadian disruption alters cardiac function and glucose regulation in mice”Published in Nature Portfolio: Biological Timing and Sleep📍 Calgary, Alberta—The Deets with Duddy is Calgary’s Late-Night Show — in podcast form.Hosted by Jeff Dudder (“Duddy,” @duddydoesit), the show features real conversations with the people shaping Calgary—artists, athletes, entrepreneurs, chefs, scientists, creators, and community leaders.📍 Based in Calgary, Alberta🆕 New episodes every Monday🎥 Full episodes on YouTube📲 Instagram: @thedeetswithduddy
