Could your daily sunlight exposure be the missing link in your health routine?
In this illuminating episode, Ricky and Roderick dive deep into the surprising science of sunlight, exploring how natural light affects everything from melanin production and mood to immunity and mitochondrial health.
Discover the real reason vitamin D might just be a stand-in for something much bigger, and why modern artificial lighting may be sabotaging your well-being.
They also tackle hot topics like infrared therapy, the biological wisdom of skin pigmentation, and how weather patterns can subtly shift your mental and physical state.
So, whether you're basking on a terrace or buried under LEDs, this is your guide to reclaiming the light your body was built for.
