Light exists on a spectrum of wavelengths, each with distinct properties and effects on human biology. Among these, red and near-infrared light stand out for their unique benefits, which is why they are a cornerstone of Luminousred devices. Let’s dive into bioactive wavelengths, their impact, and why red and near-infrared light are particularly beneficial.
Types of Bioactive Light Explained
Bioactive light refers to wavelengths that interact directly with biological processes in our bodies. Here are the primary types:
- Blue Light
- Blue light helps regulate the circadian rhythm, the internal process that governs the sleep-wake cycle.
- However, in modern environments, excessive exposure from screens, fluorescent lights, and other artificial sources can disrupt this rhythm, leading to fatigue and poor sleep quality.
- Sources: Screens, LED lights.
- Learn more about blue light’s effects.
- UV Light
- UV light enables the synthesis of Vitamin D, crucial for bone, teeth, and muscle health, as well as immune support.
- While beneficial in moderation, overexposure can damage tissue, causing sunburns or increasing the risk of skin cancer.
- Sources: Sunlight.

- Far-Infrared Light
- Far-infrared wavelengths generate heat, stimulating cellular activity and encouraging detoxification.
- This type of light is the core of infrared saunas, which are excellent for relaxation but differ significantly from red-light therapy devices in their mechanism and effects.
- Find out how far-infrared differs from near-infrared light.
- Red Light
- Red light wavelengths (620–700 nm) penetrate the skin, boosting mitochondrial activity to produce ATP, the energy currency of cells.
- Benefits include enhanced collagen production, reduced wrinkles, and accelerated wound healing.
- Sources: Red-light therapy devices, LEDs.
- Learn more about red-light benefits.
- Near-Infrared Light (NIR)
- Near-infrared light (700–1400 nm) penetrates deeper into tissues than red light. It addresses inflammation, muscle recovery, and deeper pain relief.
- NIR light is invisible to the naked eye but incredibly effective for internal health benefits.

Why Red and Near-Infrared Light?
Red and near-infrared light are often highlighted for their complementary effects:
- Surface vs. Deep Penetration: Red light primarily benefits the skin by promoting collagen production, which improves wrinkles, scars, and wound healing. Near-infrared light penetrates deeper to target muscles, joints, and internal tissues, alleviating inflammation and aiding recovery.
- Research Backing: Studies overwhelmingly support the use of red and near-infrared light for a variety of therapeutic benefits. Most clinical research focuses on wavelengths between 630–850 nm, the range Luminousred devices use.
- Dual Usage: You can use both wavelengths simultaneously for comprehensive health benefits.
