Carrie Bennett on Circadian Health, Light, and Reconnecting Your Body for Better Energy, Sleep and Hormonal Balance
In this episode, I’m joined by Carrie Bennett, a clinical nutritionist and educator in quantum biology, for a powerful conversation on how the most overlooked elements of our environment light, water, and our connection to the earth are fundamentally shaping our health.
Carrie shares her journey from molecular biology into a more holistic, root cause approach to wellness, and explains why so many people, especially in midlife, feel out of sync, exhausted, and hormonally imbalanced. At the core of this conversation is circadian health, the idea that our bodies are designed to operate in rhythm with natural light and darkness. As Carrie explains, “our body is in sync with the daytime and darkness,” and when that rhythm is disrupted, it can impact everything from energy and sleep to digestion and hormones.
We dive deep into the science of light, not just as something that helps us see, but as a powerful source of biological information. “Light is information, not just support for vision,” and the timing, intensity, and type of light we’re exposed to throughout the day directly affects our cortisol levels, melatonin production, and mitochondrial function. Carrie breaks down why that morning surge of cortisol is actually essential, boosting energy, metabolism, and digestion when it’s aligned properly with natural sunlight.
We also explore practical ways to optimise light exposure in a modern world, from getting natural morning light into your eyes, to understanding when and how to use blue light blockers, and how shift workers or frequent travellers can better support their circadian rhythm. Carrie shares simple but powerful strategies that can make a noticeable difference in how you feel day to day.
Hydration is another key theme, but not in the way you might expect. Carrie explains that true hydration goes far beyond just drinking water and is about how water interacts with your cells and supports mitochondrial health, which is central to energy production and overall vitality.
We also discuss grounding and earthing, and how reconnecting physically with the earth can help reduce inflammation, regulate the nervous system, and support recovery. For many people navigating stress, burnout, or hormonal changes, these simple, accessible practices can be incredibly impactful.
A big part of this conversation focuses on midlife, particularly perimenopause and menopause, and how circadian disruption can worsen hormonal symptoms. Carrie explains how aligning with natural rhythms can support hormonal balance, improve sleep, and help you feel more stable and energised during this phase of life.
We also touch on sleep, how to optimise melatonin production, manage stress, and improve sleep quality, as well as practical tools for dealing with jet lag and travel.
This episode is a reminder that your body isn’t broken, it may just be out of alignment with the environment it was designed for. And the good news is, many of the most powerful tools to support your health are simple, free, and available to you every day.
