Natural sunlight for optimum health☀️🔆💪👨⚕️
Sunlight provides SO much more than Vitamin D.
Research confirms t passes through parts of the body and improves mitochondrial function.
This improves nightly brain-cleaning AND vision.
A 2025 paper published in Scientific Reports investigated how longer wavelengths of sunlight (near-infrared light) interact with human tissue. 👉Longer wavelengths in sunlight pass through the human body and have a systemic impact which improves vision
These wavelengths are much different from the blue-heavy artificial light most people live under today.
And they behave very differently in the body. 🔴
Longer wavelengths
Here’s what happens 👇
1️⃣ Infrared light penetrates tissue
Longer wavelengths of light (around 700–1000 nm) can pass through skin and soft tissue much more easily than visible light.
Researchers demonstrated this by shining an 850 nm light source through the human hand, showing how deeply these wavelengths can travel through biological tissue. ⚡️
2️⃣ Mitochondria absorb this light
Mitochondria (the energy factories in your cells) have molecules that respond to near-infrared wavelengths.
When stimulated:
Mitochondrial activity increases. 📈📈📈
This process is called photobiomodulation, which I explain in my book.
More mitochondrial activity → more energy (ATP). ⚡️
3️⃣ The eyes benefit from mitochondrial support
Your retina has one of the highest energy demands in the entire body.
Healthy mitochondrial function is critical for:
✅Overall retinal health
✅Visual sensitivity
✅Color perception
✅Night vision
4️⃣ Vision improvements were MEASURABLE
Participants exposed to these wavelengths showed improvements in color sensitivity:
+16% improvement → tritan (blue-yellow) sensitivity 🔵🟡
+9% improvement → protan (red-green) sensitivity 🔴🟢
These improvements were linked to enhanced mitochondrial performance.
Modern lighting may remove these signals
Most indoor environments are dominated by:
✔️Artificial blue-heavy light
✔️LED lighting
✔️ Screens
These sources often lack the same wavelengths in natural sunlight. ❌
Meaning our cells receive FAR fewer of the biological signals we evolved with.
Sunlight also improves deep sleep and brain cleaning
During sleep, brain cells shrink by ~65% to create space to remove toxins. 🧠
A 2023 study found this glymphatic system works best during stage 3 NREM sleep. (also known as “deep sleep”)
How do you increase deep sleep?
DAILY SUNLIGHT ☀️
Takeaways
Sunlight provides your body with much more than just Vitamin D.
Natural sunlight contains infrared wavelengths that interact DIRECTLY with your cellular energy systems, and help you brain clean itself.
Even small amounts help support 👇
✅Mitochondrial function
✅Visual performance
✅Circadian biology
✅Eye health
Remember the GOLDEN RULE 👉Get sunlight regularly, but don’t burn. ☀️
