From Skin to Sleep: The Science Behind Red Light Therapy
Have you ever thought about how much light influences your health? Most of us obsess over diet, exercise, and supplements—but overlook one of the most fundamental health drivers: light. The truth is, artificial blue light after sunset disrupts your sleep, hormones, and even your long-term well-being. As Andy Mant, co-founder of Bon Charge, puts it:
“Light is a double-edged sword. When used correctly, it’s fantastic. When used incorrectly, it can silently sabotage your health.”
In this article based on an episode of the QBC Podcast, host Meredith Oke and Bon Charge founders Katie and Andy Mant cover why blocking blue light at night is essential, how to do it effectively, and why small changes like wearing blue light blocking glasses can make a huge difference. Plus, we’ll dive into red light therapy for anti-aging—because looking good and feeling great should go hand-in-hand.
What is Blue Light and Why It Matters?
Light is more than illumination—it’s a signal to your body. Our ancestors lived in harmony with natural light cycles: sunrise triggered alertness; sunset signaled rest. This system, called the circadian rhythm, governs your hormones, mood, and metabolism.
But modern life flipped the script. Artificial lighting and LED screens emit concentrated blue light, tricking your brain into thinking it’s still daytime—even at midnight. This blocks melatonin, your sleep hormone, leaving you wired at night and tired during the day.
Andy explains:
“Our body clock can’t distinguish between sunlight and artificial light. When blue light floods your eyes after sunset, your body stays in ‘day mode,’ cortisol stays high, and melatonin stays low. Sleep quality tanks—and health issues follow.”
Common Misconceptions About Blue Light
Many people think:
✅ “I sleep fine, so I don’t need to worry.”
Reality: Poor sleep quality (REM and deep sleep) can exist even if you fall asleep quickly.
✅ “Any blue light glasses will do.”
Reality: Most glasses only block a small spectrum of blue light—not enough to protect melatonin production. Bon Charge glasses are designed to block the exact wavelengths that disrupt sleep.
✅ “This is just a health trend.”
Reality: Like diet and exercise, light management is a biological necessity, not a fad.
Actionable Strategies to Protect Your Sleep
- Wear True Blue Light Blocking Glasses
- Choose glasses that block 100% of blue light from 400–550 nm.
- Wear them 2–3 hours before bed.
- Dim Your Environment
- Replace harsh LED bulbs with circadian-friendly lighting.
- Use dim lamps in the evening instead of overhead lights.
- Limit Screen Time at Night
- Use apps like f.lux, Night Shift or Iris to reduce blue light on screens.
- Better yet—combine with blue light glasses for full protection.
- Start Your Day with Natural Light
- Go outside within 30 minutes of waking to set your circadian rhythm.
- Try Red Light Therapy
- Supports skin health, muscle recovery, and relaxation.
- Bon Charge’s Red Light Face Mask combines red (surface-level) and near-infrared light (muscle relaxation) for holistic anti-aging benefits.
Real-Life Story: From a Bedroom Idea to a Global Wellness Brand
Bon Charge began as a passion project in Andy and Katie Mant’s bedroom. Frustrated by clunky safety goggles and misleading products, they created stylish, scientifically-backed blue light blockers. What started as a side hustle grew into a global brand with a 35-person team—built on education and empowerment.
“We knew this wasn’t just a product; it was a movement to help people live in harmony with light,” says Katie.
The Beauty Bonus: Reverse Aging with Red Light Therapy
Let’s be honest—how we look matters. But instead of injectables and harsh chemicals, red light therapy works with your body, not against it.
- Red Light: Improves skin tone, reduces fine lines.
- Near Infrared Light: Penetrates deeper to relax muscles, smooth skin naturally.
*”I use our red light face mask 3–4 times a week,” Katie shares. “It’s about feeling authentic and looking like the best version of yourself—without toxins or surgery.”
FAQs
Q: Will I notice a difference right away with blue light blocking glasses?
A: Yes—most people report better sleep the first night.
Q: Can I just dim my lights instead?
A: It helps, but screens and LEDs still emit disruptive light. Glasses provide the best protection.
Q: Is this only for biohackers?
A: No! These habits are simple and sustainable. Even small changes—like wearing glasses at night—make a huge impact.
Sleep isn’t a luxury—it’s the foundation of health. Blocking blue light after dark is one of the simplest, most effective ways to improve your energy, mood, and longevity. Combine that with morning sunlight and red light therapy, and you’ll look and feel your best—naturally.
