Red light therapy at home means using a red and near-infrared light device (like a wearable belt or a panel) for 10 to 20 minutes a day to help ease pain, calm inflammation and support recovery, without pills, heat or a clinic visit. It is one of the simplest drug-free tools you can add to your day, and the research behind it for pain and joints is genuinely encouraging. This guide walks you through how it works, what to use it for, how to choose a device, and how to build a simple routine that fits real life.
Key takeaways
- Red light therapy uses two wavelengths: red (around 660nm) for the surface and near-infrared (around 850nm) for deeper tissue and joints.
- Most people use it for 10 to 20 minutes per area, 3 to 5 times a week.
- Pain and inflammation often ease within 1 to 2 weeks, with fuller results building over 3 to 6 weeks of regular use.
- At home you can choose from wearable belts, wraps, pads, face masks or freestanding panels.
- It is generally very safe, but check with your GP if you are pregnant, on photosensitising medication, or undergoing treatments like chemotherapy.

What is red light therapy?
Red light therapy (also called photobiomodulation or low-level light therapy) is the use of specific wavelengths of red and near-infrared light to support the body's natural repair processes. Unlike the UV light that can damage skin, these wavelengths are gentle and produce no heat damage. The light is simply absorbed by your cells, where it helps them work more efficiently.
It started life in clinics and even in early NASA research on wound healing and plant growth. Today, thanks to affordable wearable devices, the same therapy is something you can do on the couch in Australia while you watch the footy.
How does red light therapy work for pain and recovery?
The short version: red and near-infrared light is absorbed by the mitochondria, the tiny "power plants" inside your cells. This nudges them to produce more ATP, the energy your cells use to repair and function. More energy means tissue can recover faster.
For pain and inflammation specifically, three things happen:
- More blood flow. The light triggers the release of nitric oxide, which relaxes blood vessels. Better circulation brings oxygen and nutrients to a sore or injured area.
- Less inflammation. Red light helps dial down inflammatory signalling, which lowers the chemicals that keep an area swollen and sore.
- Natural pain relief. It can prompt the release of endorphins, your body's own pain relievers.
That combination is why so many people reach for it instead of another round of tablets.
What can you use red light therapy for?
Red light therapy is used for a wide range of everyday complaints. The evidence is strongest for pain, joints and recovery, and more emerging for skin and sleep. Here is a quick map of the common uses.
| Use | What people use it for | Evidence |
|---|---|---|
| Joint pain | Knees, hips, shoulders, arthritis stiffness | Strong |
| Back and muscle pain | Lower back, neck, general soreness | Strong |
| Muscle recovery | After training, labour or long days on your feet | Good |
| Skin | Collagen, fine lines, tone, blemishes | Good |
| Wellbeing | Sleep and general recovery support | Emerging |
The evidence for joints is worth pausing on. A 2024 meta-analysis found that light therapy reduced knee osteoarthritis pain by around 40% after eight weeks, and earlier trials reported large drops in joint swelling versus placebo. For a simple, drug-free tool, that is a meaningful result.

Red light vs near-infrared: what do 660nm and 850nm do?
You will see two numbers on quality devices: 660nm and 850nm. They are not marketing fluff. They do different jobs, which is why the best devices combine both.
| Wavelength | Type | Reaches | Best for |
|---|---|---|---|
| 660nm | Red light | Skin and surface tissue | Surface inflammation, skin, tone |
| 850nm | Near-infrared | Deep tissue, muscles, joints | Joint pain, muscle recovery, deep aches |
Think of red light as the surface worker and near-infrared as the one that reaches the deep joint. For pain and recovery, you want a device that runs both. Every EliteRelief red light device uses this dual-wavelength combination.
Some higher-end devices go further. The EliteRelief Pro Panel range, which is TGA registered as a medical device in Australia, delivers a fuller 9-wavelength therapeutic spectrum. That means extra wavelengths beyond 660nm and 850nm, aimed at a broader range of skin, tissue and recovery benefits in a single full-body session. If you are just starting out, though, a quality 660nm and 850nm device covers the essentials, so you do not need the full spectrum to feel the benefits.
What red light therapy devices can you use at home?
There is no single "best" device, only the best one for where your pain is and how you like to use it. Here are the main types.
- Wearable belts: wrap around the back, stomach, hips or thighs. The easiest hands-free option for larger areas and everyday pain.
- Joint wraps: shaped and cordless for knees, elbows and shoulders.
- Mini wraps: compact, for wrists, ankles and small joints.
- Pads: large flexible mats for broad coverage across the back or legs.
- Face masks: multi-wavelength LED masks for skin.
- Panels: freestanding lights for full-body sessions. EliteRelief's Pro Panel range is TGA registered as a medical device in Australia.
For most people starting out, a wearable belt is the sweet spot. It is hands-free, covers the areas that ache most (the back and legs), and it is easy to stay consistent with. If you want more power in a fully portable, cordless design, the PRO belt steps things up.

How to use red light therapy at home (a simple routine)
The best routine is the one you will actually stick to. Here is a straightforward way to start.
- Position the device on clean, bare skin. The light works best with direct contact or a short distance, not through thick clothing.
- Run one area for 10 to 20 minutes. Higher-output devices need less time; gentler ones need a little more.
- Repeat 3 to 5 times a week. For a flare-up, daily use in the early days is fine.
- Relax while it works. With a hands-free belt you can read, work or watch TV.
- Stay consistent. Results build with regular use, so a shorter daily habit beats one long weekly session.
A common mistake is stopping after a couple of goes. Think of it like the gym: the magic is in showing up regularly, not in any single session.
How long does red light therapy take to work?
Many people feel some relief from pain and inflammation within the first 1 to 2 weeks. Fuller results, the kind you notice in day-to-day movement, usually build over 3 to 6 weeks of consistent use. Skin changes tend to take a little longer, often 8 to 12 weeks.
If you have had pain for years, give it a proper run of at least a month before you judge it. That is exactly why EliteRelief includes a 60-day risk-free trial: it takes the pressure off, so you can give it real time.
Is red light therapy safe? Side effects and who should check first
Red light therapy is generally considered very safe, and most people have no side effects at all. When they do occur they are usually mild, such as slight warmth or temporary redness. There is no UV, so it does not carry the skin-damage risk of the sun or a tanning bed.
That said, it is sensible to speak with your GP first if you:
- are pregnant,
- take medication that makes you sensitive to light (photosensitising medication),
- have a history of skin cancer or a light-sensitive condition, or
- are undergoing serious treatment such as chemotherapy.
Never look directly into the LEDs, and if you are using it on your face, close your eyes or use the supplied eye protection.
How to choose the right device for you
Cut through the noise with three simple questions:
- Where is your pain? Back, hips and large areas suit a belt or pad. Knees and elbows suit a wrap. Whole-body suits a panel.
- Does it use both wavelengths? Look for 660nm and 850nm together, so you cover both surface and deep tissue.
- Is it backed? A money-back trial and a real warranty tell you the brand stands behind it. EliteRelief offers a 60-day risk-free trial and up to 4 years warranty, and the Pro Panel range is TGA registered.
If you are not sure, start with a wearable belt. It is the most versatile first device, and you can always add a wrap or panel later. You can browse the full range in our wearables collection or explore back and body support for everyday relief.
Frequently asked questions
Does red light therapy really work?
For pain, joints and recovery, the evidence is genuinely encouraging. A 2024 meta-analysis found around a 40% reduction in knee osteoarthritis pain after eight weeks. Results vary between people, which is why a risk-free trial is worth having.
How often should I use red light therapy?
Most people use it 3 to 5 times a week, for 10 to 20 minutes per area. During a flare-up, daily use in the first week or two is fine.
Can you overdo red light therapy?
More is not better. Sticking to the recommended session length gives your cells what they need without wasting time. Going much longer does not speed things up.
Is red light therapy the same as infrared heat?
No. Infrared heat lamps warm the skin. Red light therapy uses specific wavelengths (660nm and 850nm) that your cells absorb to support repair, with little to no heat.
Can I use it through clothing?
It works best on bare skin or through very thin fabric. Thick clothing blocks the light, so place the device directly on the area where you can.
Is red light therapy safe to use every day?
For most people, yes. Daily short sessions are fine and often helpful early on. If any of the safety points above apply to you, check with your GP first.
