In this powerful and eye-opening episode, Dave speaks with Theresa Bug, a former German police officer turned online health coach, holistic nutritionist, and advocate for natural light, grounding, and mitochondrial health.

🌿 Theresa shares her inspiring journey from a high-stress career in law enforcement—across Paris, London, Israel, and Africa—to deep healing through sunlight exposure, circadian rhythm restoration, and reconnecting with nature. Her story is a testament to the life-changing power of simple yet profound lifestyle changes.

💡 Key Topics Covered:

• How chronic stress and PTSD led her to holistic health
• The science behind morning sunlight and mitochondrial function
• Why grounding (earthing) and going barefoot can reset your nervous system
• The truth about blue light, screen time, and modern lighting
• The problems with supplement culture vs. real food and lifestyle
• How to eat seasonally and locally for optimal health and gut function
• Why gyms might be harming us more than helping—and how to exercise in harmony with nature
• Insights into raw milk, hydration, EMFs, red light, sleep, and ancestral living

☀️ This conversation explores how sunlight analysis, circadian health, and shadow-free living can transform your physical and mental health—especially in a world of artificial light, disconnected routines, and overprescribed medications.

In this illuminating episode, we're joined by Austrian engineer Viktoria Neumueller, a passionate advocate for sunlight-optimized architecture and energy-efficient building design. With a background in planning heating, cooling, and ventilation systems, Viktoria brings rare insight into how thoughtful building orientation and solar exposure can dramatically reduce heating costs, enhance comfort, and even transform quality of life.

We dive deep into:

• Why shadow mapping and sunlight analysis should be a first step in architectural design
• How ignoring solar orientation can cost homeowners thousands over a building’s lifetime
• Viktoria's personal mission to help homeowners, builders, and architects rethink natural light integration
• The surprising resistance from the construction industry—and how she’s challenging it

Whether you're planning a new build, renovating a home, or simply fascinated by how sunlight and design intersect, this episode will inspire a new way of seeing your space.

In this episode, Dave chats with Professor Glen Jeffery, a neuroscientist at University College London’s Institute of Ophthalmology, whose research investigates how light, particularly long-wavelength red and infrared, influences human health, metabolism, and ageing.

Glen Jeffery is recognised as one of the world's leading researchers in exploring how light interacts with our bodies.

Glen explains how sunlight penetrates the body, enhancing mitochondrial function, improving vision, and even boosting motor skills like grip strength. He warns that modern LED lighting, while energy-efficient, can harm metabolic health compared to incandescent bulbs that emit beneficial infrared light.

They examine the public health consequences of our “infrared starvation,” the role of mitochondria in ageing, and the unexpectedly affordable potential solutions, such as rethinking indoor lighting and spending 20–30 minutes outdoors. Glen makes comparisons to historical issues like scurvy, emphasising the need for urgent policy reforms before our ageing, indoor-bound populations face worsening health crises. Practical advice includes seeking more natural light, using infrared-rich lighting where feasible, and adopting lifestyle changes that incorporate movement and sunlight exposure.
