Red light therapy vs. natural sunlight: Which is better?

 Red Light Therapy (RLT)

Pros:
✅ Targeted wavelengths (630–850 nm) for collagen, ATP, and tissue repair.
✅ No UV rays—safe for daily use without skin damage.
✅ Controlled dosage—consistent results with no risk of burning.
✅ Year-round access—works indoors, unaffected by weather.

Best For:

• Skin rejuvenation (acne, wrinkles, scars)
• Muscle recovery & joint pain
• Chronic inflammation or autoimmune support

 Natural Sunlight

Pros:
✅ Full-spectrum light (UV + visible + infrared)—boosts vitamin D, mood, and circadian rhythm.
✅ Free & accessible (with moderation).
✅ Broader immune benefits (e.g., UVB stimulates vitamin D for immune function).

Risks:
UV damage—aging, sunburn, and skin cancer risk.

Weather/climate dependent—hard to get in winter or polluted areas.

Best For:

• Vitamin D synthesis
• Mental health (serotonin boost)
• General wellness (in short, safe doses)

 Key Differences

Which Is Better?

• Choose RLT if: You want targeted, safe treatments for skin, pain, or recovery.
• Choose sunlight if: You need vitamin D or mood enhancement (with sunscreen!).
