In this episode of the vrss podcast, we sit down with Sarah Jeffries to unpack the science of sleep, brain health, and performance - and why sleep may be the most overlooked skill in combat sports and high-performance training. Sarah is a registered nurse with a Master’s in Nursing Science, a nurse educator, and a leading voice in sleep education. She breaks down what’s actually happening in your brain when you sleep, including how deep sleep and REM sleep work together to support recovery, learning, emotional regulation, and long-term brain health. We explore: * Why sleep is a trainable skill, not a personality trait * What “cleaning your brain” actually means from a neuroscience perspective * How sleep deprivation affects focus, reaction time, mood, and performance * The role of deep sleep in muscle repair, hormones, and recovery * Why REM sleep matters for memory, learning, and emotional resilience * How poor sleep disrupts appetite, decision-making, and training consistency * Practical, evidence-based tools to improve sleep without biohacks or gimmicks This conversation is especially relevant for fighters, athletes, coaches, and anyone training hard - but it’s just as important for anyone navigating stress, pressure, or high cognitive load. Sleep is free. It’s foundational.And it’s one of the most powerful tools you have - if you know how to use it.
