Why do we sneeze — and why does it feel so good? Roxie unpacks the science, strangeness, and secret beauty behind this tiny explosion of air and instinct. From the “sneeze center” in your brainstem to sunlight sneezes, pepper triggers, and ancient myths, she explores how something so small can say so much about being human. Warm, funny, and oddly poetic — it’s another cozy late-night dive into the mysteries of the body. “Be good to your noses, be kind to your bodies… and stay curious.”

In this cozy late-night episode, Roxie explores one of life’s happiest mysteries — laughter. From giggling babies and ticklish rats to awkward funeral chuckles, she unpacks the science, psychology, and pure humanity behind why we laugh. With her signature warmth and wit, Roxie reveals how laughter connects us, relieves tension, boosts our health, and even helps us sleep. Blending gentle humor with thoughtful science, she reminds listeners that laughter isn’t just about jokes — it’s how our brains say, “You’re safe, you belong, you’re alive.”

In this cozy (and slightly giggly) deep dive, Roxie unpacks one of biology’s strangest mysteries — sleep. Why do we spend a third of our lives basically unconscious, vulnerable, and drooling on our pillows — and yet, somehow, it’s the key to survival? Following last week’s episode on Why We Dream, Roxie takes us behind the eyelids to explore what’s really happening when we drift off. From the body’s late-night repair crew and the brain’s glymphatic “janitors,” to the memory-sorting chaos of REM cycles, this episode explores how sleep acts as our built-in reset system — for our cells, our minds, and even our emotions. She also tackles what happens when we don’t sleep (spoiler: it’s not pretty), why blue light ruins our bedtime, and how our circadian rhythm keeps us synced with the sun — unless, of course, we’ve been doomscrolling at 1 a.m. Between relatable stories, easy-to-grasp science, and Roxie’s signature warmth, “Why Do We Sleep?” reminds listeners that rest isn’t wasted time — it’s the most productive “doing nothing” you’ll ever do. So, grab your blanket, silence your phone, and get ready to appreciate the one thing your body’s been begging you for since… forever.

In this thoughtful and funny second episode, Roxie explores one of the most mysterious questions in science and everyday life — why we dream. Blending humor, personal stories, and real research, she takes listeners on a guided tour through what happens in our brains while we sleep. Roxie breaks down what dreams are, when they occur (REM vs. non-REM sleep), and the leading scientific theories that try to explain them — from memory consolidation and emotional processing to random neural noise and threat simulation. She also touches on how dreams might help with creativity, social rehearsal, and emotional healing. Listeners get a mix of neuroscience, psychology, and relatable storytelling — including a hilarious dream about croissant-shaped celebrities and a few listener submissions that show just how bizarre our minds can be. Roxie also gives practical insights: How to start a dream journal What affects dream recall The truth about lucid dreaming and nightmares How medications and emotions can change dream patterns By the end, she wraps it all up with a reminder that dreams are the brain’s overnight workshop — a mix of memory, emotion, creativity, and chaos — and worth paying attention to, even when they’re weird. 💭 “Dreams are how the brain stays curious — even while we sleep.”

In this episode of Voices of Discovery, host Roxie Robinson takes listeners on a deep dive into the fascinating world of human anatomy and physiology. From the heart that pumps life-sustaining blood to the brain that controls every thought and movement, Roxie provides a comprehensive overview of the body’s intricate systems and their interconnected roles in keeping us alive and thriving.
