Humans have always oriented themselves toward light. We seek it in the morning. We feel its absence in winter. We understand in our bodies, even before we can explain it in our minds, that light is not just something we see, but something that shapes how we feel.

Modern life has changed our relationship with light in ways we rarely stop to name. We spend most of our waking hours under artificial lighting, behind glass, indoors — separated from much of the natural light our biology evolved with. The effects are subtle but cumulative, and many people describe a low-level sense of depletion that ordinary rest doesn't quite resolve.

Infrared and red light devices — red light panels, near-infrared devices, far-infrared mats — are one way people try to bring some of that light exposure back into daily life. This article explains

what they are, what the research does and doesn't support, and how to think about them safely.

We'll be honest throughout about where the evidence is solid and where it's still emerging — because for our community, that honesty matters more than enthusiasm.

What Is Infrared Light Therapy?

First, the landscape — because “infrared devices” covers several related but distinct tools, and knowing the difference helps you understand what each one is and isn't.

The broad research category is called photobiomodulation — exposing the body to specific wavelengths of red and near-infrared light, typically in the 600 to 1,100 nanometer range. These wavelengths are absorbed by the body's cells, particularly the mitochondria, the energy- producing structures inside cells.

• Red light (roughly 630–700 nm) penetrates the surface layers of skin and tissue. It's most studied in the context of skin appearance and surface-level applications.

• Near-infrared light (roughly 750–1,100 nm) penetrates more deeply, into muscle and joints. It's the wavelength most studied for muscle recovery and pain research — and, in early-stage research, for effects reaching deeper tissue.

• Far-infrared is heat-based rather than light-based in the usual sense — this is what infrared saunas and heat mats use, warming the body directly rather than heating the surrounding air. Its effects are distinct from red and near-infrared light.

A distinction worth holding onto: some light-therapy devices are FDA-cleared medical devices for specific uses (certain skin conditions, certain kinds of pain), used according to specific instructions. Consumer red-light panels and infrared mats sold for home wellness are generally marketed as general wellness products — they are not the same as the cleared medical devices,How Can Infrared Devices Help My Wellbeing? and research on one doesn't automatically transfer to the other. The devices offered through Luna Sol are general wellness products, and we describe them as such.

The Science: What Researchers Think Is Happening

Here is the cellular story, kept simple — and framed honestly as a leading hypothesis rather than settled fact. Inside mitochondria there is a molecule called cytochrome c oxidase, which absorbs red and near-infrared light. Researchers propose that this absorption may increase ATP production (the cell's fuel), influence oxidative stress and nitric oxide (affecting local blood flow), and modulate inflammation signaling — nudging cells toward more effective self-repair. This mechanism is supported by laboratory research and is the most widely cited explanation for photobiomodulation's observed effects, though exactly how it translates to real-world outcomes in people is still being worked out.

The useful way to hold it: red and near-infrared light don't heal tissue directly; the theory is that they support the conditions in which the body does its own repair. That framing is honest to where the science actually stands.

The NASA Connection

Interest in modern red and near-infrared light research grew, in part, out of space program work in the 1990s, when researchers explored red light as a way to support cell growth and wound healing in the challenging environment of spaceflight. That work helped open a field of study that has since produced a large and growing body of research — of varying size and quality.

Today, photobiomodulation is studied and used in dermatology, physical therapy, sports medicine, and research settings. It is no longer fringe. It is also, in many of its applications, still an actively developing science rather than a settled one — both things are true at once.

What the Research Explores — and What It Doesn't Establish

Rather than promise outcomes, here's an honest map of where the research is stronger and where it's preliminary.

• Skin appearance: this is where consumer red light has its most established footing. Research and FDA clearances exist for specific red-light devices in areas like skin appearance and collagen. Effects are modest and gradual, and results vary by device and person. We include this not as vanity but as dignity — grief and caregiving can show on the body, and tending to how you look and feel like yourself is part of caring for yourself.

• Muscle recovery and physical ease: many users describe less soreness and easier movement, and there's real research interest in red/near-infrared light for muscle

How Can Infrared Devices Help My Wellbeing? recovery. Much of the stronger evidence involves specific devices and protocols. A wellness panel or mat is not a pain treatment — if you live with significant or persistent pain, talk with your doctor, and never reduce or stop pain medication without your prescriber's guidance.

• Relaxation and rest: far-infrared mats in particular are deeply relaxing for many people — a warm, passive, 15-to-20-minute practice of lying still. This restful experience is real and immediate, independent of any deeper claim.

• Sleep and circadian rhythm: there's genuine scientific interest in how light exposure and its timing affect the sleep-wake cycle, and some people find a light routine helpful.

The specifics — which wavelength, what timing, how much — are still being studied, so treat this as an area to experiment with gently, not a guaranteed fix.

• Brain and mood: this is an area of active, early-stage research, and it's also where we want to be most careful. Some small studies have explored near-infrared light and mood, including in depression, and the findings are interesting enough that researchers are pursuing them. But these studies are small and preliminary, and none of it makes a home wellness device a treatment for depression, anxiety, brain injury, or any mental health or neurological condition. If you're struggling with your mood — as so many caregivers and grievers do — please talk with a doctor or therapist. That's the real first step; a light panel is not a substitute for it, and we won't pretend otherwise.

The Luna Sol Connection: Light as the Thread Between Sol and Luna

We speak at Luna Sol of the balance between warmth and stillness, between Sol's fire and Luna's quiet. Light sits naturally in that framework, because it holds both.

The far-infrared warmth of a sauna mat is Sol energy — warming, activating, coaxing the body toward openness and release. The gentle red light of a panel is Luna energy — quiet, invisible, working in the background while you rest.

Grief is not only an emotional experience; it settles into the body — into disrupted sleep, into tension, into the sense of a body running on empty. Infrared devices can't grieve for you, and they can't heal grief. What a gentle light-and-warmth practice can offer is something smaller and real: a consistent, low-effort pocket of rest and self-tending in a season that rarely allows one.

That is what we mean when we say Luna Sol supports the whole person — not with promises, but with quiet, honest tools for rest.

The Devices, and How to Think About Them

The world of infrared devices can feel overwhelming. Here's a practical frame.

• Red and near-infrared light panels range from small handheld units to full-body panels. You sit or stand before the panel, usually 10 to 20 minutes, at the distance the manufacturer specifies. They produce little heat and need no recovery time.

• Infrared mats and pads deliver far-infrared warmth through a mat you lie on — among the most passive of wellness tools. Some combine far-infrared heat with other features; follow the manufacturer's guidance for any combined device.

• Infrared saunas (covered in our companion article) use far-infrared warmth to heat the body rather than the air, for a more immersive, full-body heat experience.

Each suits different preferences: a panel for brief targeted sessions, a mat for passive warmth and relaxation, a sauna for full-body heat. Many people enjoy combining them over time. Choose based on comfort and what fits your life — and, if you have any medical condition, on your provider's guidance.

Using Infrared Devices Safely and Well

• Protect your eyes — this one is not optional. Wear the eye protection the manufacturer provides or recommends, especially for face-directed sessions and with near-infrared devices. Near-infrared light is largely invisible, so it doesn't trigger your natural blink-and-look-away reflex, and concentrated exposure can pose a risk to the eyes. Never stare directly into the LEDs. If you have any eye condition, check with your eye doctor first.

• Follow the device's distance and time specs. Panels are designed to be used at a particular distance (often 6 to 18 inches) and duration. More is not better; follow the instructions rather than guessing.

• Consistency over duration. A short daily session generally does more than an occasional long one — the body responds to regular, repeated exposure, much as it does to exercise.

• Mind timing if you're using it for routine. Some people prefer morning light as part of a wake-up routine; others use warmth in the evening to wind down. Experiment gently and notice what helps you.

• Be patient, and skip the stopwatch on results. Any benefits people notice tend to build gradually with consistent use rather than appearing overnight, and experiences vary widely. Approach it with curiosity rather than a fixed timeline or expectation.

What Infrared Therapy Is Not — and Who Should Take Care

As always, we want to be honest with you. Infrared and red light devices are not a substitute for medical care, mental health treatment, or grief support, and they are not a treatment for any medical or mental health condition. The research in areas like mood and brain health, while interesting, is still developing, and individual experiences vary. If you are managing any medical condition, please speak with your healthcare provider before adding any new practice.

Some people should take particular care or check with a doctor first:

• Photosensitivity. If you have a light-sensitive condition (such as lupus or certain skin

conditions) or take a medication that increases light sensitivity — some antibiotics, acne medications, diuretics, and others — talk with your doctor or pharmacist before use.

• Active cancer or skin lesions. Do not use light devices over an area of active cancer or over undiagnosed skin lesions without a physician's guidance.

• Eye conditions, pregnancy, thyroid or other neck-area conditions, epilepsy (for any flickering-light device), and any implanted device in a combined heat/PEMF mat — all warrant a conversation with your provider first.

• Overheating with far-infrared warmth. Stay hydrated, don't overdo the heat, and stop if you feel dizzy, faint, or unwell — the same common-sense cautions that apply to any heat practice.

A Final Word

There is something quietly appealing about the idea that light — freely given by the sun, and now available in your own home — might be a small, gentle support for a tired body. Not a cure. Not a promise. A modest, consistent practice of rest and self-tending.

We live in a world that tends to believe healing has to be hard — that if it doesn't cost you effort or discomfort, it can't be working. A quiet ten minutes with warmth or light gently disagrees.

Sometimes tending to yourself looks like lying still and letting your body simply rest. Come to the light, if it draws you. Let it be one small, honest part of finding your way back.

Luna Sol Wellbeing LLC offers a curated collection of premium PEMF mats and devices, infrared saunas, massage chairs, cold plunge systems, and wellness tools designed for caregivers and those walking through grief. Our philosophy is rooted in the balance of warmth and stillness — Sol and Luna — because we believe healing honors both.
