There is a conversation your body is in every single day — with light.
Long before we tracked hormones, optimised sleep, or tried to “hack” our health, the human body evolved in deep relationship with the rhythms of sunrise, daylight, dusk, and darkness. And whether we realise it or not, our biology is still responding to those ancient cues.
In this episode, I’m joined once again by Karinda Wholistix for a deep and fascinating conversation on circadian biology, sunlight, mitochondria, and the profound ways our bodies are shaped by the light environment around us. We explore how our systems read and respond to “wild light”, what begins to shift when that rhythm is disrupted, and why understanding this relationship changes the way we view hormones, energy, sleep, nervous system health, and more.
This is Part 1 of a two-part conversation — laying the foundations for understanding the intelligence of circadian rhythm and the body’s relationship with light.
About Karinda
Karinda Wholistix is a BHSc Naturopath, Fertility Awareness Educator, and Menstrual Cycle Educator based in Naarm (Melbourne), working with women online across Australia. She specialises in helping women decode what their bodies are communicating through their hormones, periods, and menstrual cycles — getting to the root of what's driving symptoms rather than simply managing them.
She is the creator of Harmonised Hormones, a naturopathic program built around deep investigation and treatment tailored entirely to the individual, and hosts Oh My Menses, a podcast dedicated to honest conversation about periods, hormones, and cyclical living.
Karinda’s mission is to help as many women as possible understand what their body has been trying to tell them & reclaim their cyclical power.
We Cover:
- The foundations of circadian biology — what circadian rhythm actually is, and the spectrum of light from sunrise through to sunset and darkness
- What is happening in those early rays of sunrise light, and the different cues associated with UVA and UVB light throughout the day
- How our eyes and skin receive and respond to sunlight
- Mitochondria, light, and energy production within the body
- Some of the body systems most impacted by light exposure — including many that are rarely discussed in relation to circadian health
- What disrupts our natural biological rhythm, and why modern environments can create mismatch within the body
