About this episode
What if getting better sleep has less to do with sleeping longer, and more to do with your daily habits?
Dr. Kristen Holmes is a performance scientist whose work focuses on sleep, recovery, circadian rhythms and the everyday behaviours that influence how well our bodies and minds perform.
In this moment, Dr. Kristen Holmes opens up about her childhood and the catalyst to her passion for health and human potential. She reveals the overlooked habits that can quietly disrupt recovery and answers common questions about sleep disruption. Is one glass of wine really going to impact my sleep? What about caffeine? If I don't have time for 9 hours of sleep every night, can my sleep still be restorative?

Episode summary
This AI-generated Shortcast summary may omit nuance. Use the original episode when context or exact wording matters.
Changing a habit is nothing beside addiction. You watched your mother struggle from childhood; what did that feel like?
At fundamental level, you feel deprioritized. My dad had integrity but worked constantly, so I figured out food and life myself. That independence can make adult attachment hard: you fear nobody will look after you. My mum had major depression and severe seasonal symptoms, never properly diagnosed or treated. That’s why light and health matter: predisposition is real, but we can reduce vulnerability.
I quit alcohol three or four months ago, despite being casual. How do you see alcohol, health, and circadian rhythms?
I use non-neutrality: does it support the person I want to be—growth, impact, presence, compassion—or not? I don’t think alcohol helps health; even one or two drinks weekly have downsides. It disrupts sleep timing and melatonin, then brings later light exposure and eating. Caffeine within eight to twelve hours of sleep can delay and fragment it.
Anyone awake more than two hours between ten at night and four in the morning counts as a shift worker. It’s a huge sacrifice with serious health and mental-health risk. Brief deactivation helps: a double inhale, then a long exhale, repeated five or ten times.
Every forty-five minutes of sleep debt can mean a five to ten percent next-day drop in executive function. Leaders may not notice the decline, but teams feel less safe. Sleep loss affects everybody you touch and raises accident risk. Circadian and environmental behaviors have to come first.
