"The Sun is the Doctor in the Sky" - How UVA and UVB Light Heal and Empower Your Health Naturally

The sun is one of nature’s most powerful healers. As Barbara O'Neill wisely stated in her book, Sustain Me, "The sun is the doctor in the sky." 

This radiant star provides essential UVA and UVB light that supports skin health, boosts mood, strengthens bones, and enhances immune function. Understanding the healing effects of UVA and UVB rays and learning how to safely harness their benefits can elevate your health and vitality naturally.

The Healing Benefits of UVA and UVB Light

UVA Light: A Morning Metabolic Boost

Timing:  UVA Light is most prominent in the early morning, shortly after sunrise.

Benefits:  

• Boosts serotonin, dopamine, and norepinephrine levels to enhance mood, focus, and fat burning.

• Promotes the production of thyroid hormones (T4 and T3) to support metabolism.

• Stimulates melanin production, providing natural sunscreen and supporting detoxification, appetite regulation, and antioxidant effects

• UVA rays penetrate deep into the skin, stimulating collagen and elastin production—key proteins for firm, youthful skin

  
  

Action Step:  Get outside during the UVA window (10 - 30 degree sun angle).  Expose your eyes and skin for maximum benefits - skip the sunglasses to allow light to reach your retina.

UVB Light: The Vitamin D Connection

Timing:  UVB Light is available during peak daylight hours, typically between late morning and early afternoon.  Availability varies by latitude and season.  

Benefits:

• UVB rays primarily trigger the synthesis of Vitamin D in your skin. This vital nutrient is essential for strong bones, muscle function, and immune defense. Adequate Vitamin D levels also support healthy sleep patterns and overall wellness.

• Boosts mitochondrial energy production and increases fat burning

  
  

Action Step:  Build your sun exposure gradually to avoid burning.  Understand your Fitzpatrick skin type to determine safe exposure times.

Smart Sun Exposure Tips:

1. Layer Your Exposure:  Start with infrared light at sunrise, move to UVA, then gradually increase UVB exposure as your skin adapts.

2. Build a Solar Callus:  Gradual, consistent exposure over time helps your skin produce melanin and build natural protection against burns.

3. Avoid Burning: Use clothing and shade as needed to protect against overexposure.

   
   

Daily Practices:

Combine Activities:  Take a morning walk during the UVA window to boost mood and metabolism.

Optimize Brightness:  Spend time outdoors throughout the day to maintain proper circadian signals.  Indoor light is too dim to match natural brightness levels.

End with Infrared Light:  Heal and soothe your skin with sunset light or red light therapy.

Harness the wisdom of the sun and Barbara O’Neill’s powerful reminder that “the sun is the doctor in the sky.” By mindfully embracing the healing powers of UVA and UVB rays, you can nurture your skin, strengthen your bones, enhance your mood, and elevate your overall health naturally—one radiant moment at a time.
