How to See Infrared Light and Why It Matters for Your Health
Dr. Seheult demonstrates a simple $22 filter that reveals hidden infrared light and explains its crucial role in mitochondrial health.
Summary
Dr. Roger Seheult demonstrates how a simple $22 infrared filter for smartphone cameras can reveal invisible near-infrared light in your environment. The filter uses rare earth metals to convert infrared wavelengths into visible red light, showing that natural outdoor environments are rich in beneficial infrared while indoor LED lighting provides none. Studies show people living in green spaces have 28% lower diabetes rates and 31% lower mortality. Research indicates near-infrared light penetrates skin to reach mitochondria, reducing oxidative stress and increasing ATP production. Modern LED lighting lacks this beneficial spectrum, while incandescent bulbs and sunlight provide it abundantly, even on cloudy days.
Detailed Summary
Near-infrared light exposure may be a missing piece in modern health optimization, and Dr. Seheult provides a practical way to visualize this invisible spectrum. Using a $22 smartphone filter made from rare earth metals, viewers can see how natural environments are saturated with beneficial infrared light that appears red through the filter, while indoor LED environments show virtually none.
The health implications are significant. Meta-analysis data shows people in green spaces have 28% lower type 2 diabetes rates, 16% lower cardiovascular mortality, and 31% lower total mortality. A Louisville tree-planting study found 13-20% reductions in inflammatory markers and 10-15% fewer strokes. Near-infrared light penetrates skin and clothing to reach mitochondria, where it reduces oxidative stress, increases ATP production, and improves glucose metabolism.
Modern indoor environments are increasingly infrared-deficient. LED lighting provides no infrared spectrum, unlike incandescent bulbs and sunlight. New 2028 lighting efficiency requirements will worsen this trend. However, even cloudy days provide substantial infrared exposure outdoors. Research shows adding incandescent lighting to LED work environments improved visual performance for up to six weeks.
The practical takeaway is clear: prioritize outdoor time for natural infrared exposure, even in winter or cloudy conditions. Indoor alternatives include incandescent lighting or red light devices, though natural sunlight remains optimal. This represents a simple but potentially powerful intervention for mitochondrial health and longevity.
Key Findings
- Natural outdoor environments provide abundant infrared light even on cloudy days, while LED indoor lighting provides none
- People in green spaces show 28% lower diabetes rates and 31% lower total mortality in meta-analysis studies
- Near-infrared light penetrates skin to reach mitochondria, reducing oxidative stress and increasing ATP production
- Adding incandescent bulbs to LED work environments improved visual performance lasting up to 6 weeks
- Most clothing fabrics allow significant infrared penetration, requiring 7+ layers to block effectively
Methodology
Educational video from MedCram featuring board-certified physician Dr. Roger Seheult demonstrating infrared visualization technology. Combines practical demonstration with review of published research studies and meta-analyses on green space health benefits.
Study Limitations
Video reviews correlational studies on green spaces without establishing causation from infrared specifically. Some research cited is still in peer review. Individual responses to infrared exposure may vary significantly.
