How to Use a Red Light Panel: A Step-by-Step Guide

Red light therapy panels have become a popular addition to home wellness routines because they're easy to use and fit naturally alongside other recovery practices. Still, using one correctly involves more than simply standing in front of the LEDs for a few minutes.

The right distance, session length, treatment frequency, and positioning all contribute to a safe and consistent experience. Since every panel has its own specifications, understanding the basics helps you get the most from your sessions while avoiding common mistakes.

In this guide, we'll walk through exactly how to use a red light panel from start to finish.

How to Use a Red Light Panel

Using a red light panel generally involves exposing the treatment area, positioning yourself at the recommended distance, selecting the appropriate settings, and completing a session for the amount of time specified by the manufacturer. While every device differs slightly, the overall process is straightforward and easy to build into a regular routine.

The following steps will help you set up your sessions with confidence.

1. Read your panel's instructions first

Before turning on your panel, take a few minutes to review the manufacturer's instructions. Even if you've used another red light therapy device before, your new panel may have different recommendations for treatment distance, session length, operating modes, or safety precautions.

General advice can be helpful, but your panel's instructions should always take priority over broad recommendations you find online.

2. Decide which area you want to treat

Choose the part of your body you want to expose before positioning the panel. Someone focusing on facial skincare will likely use a different setup than someone targeting their back, shoulders, knees, or legs after exercise.

Your panel's size also affects how much you can cover during a single session. Smaller panels require repositioning to treat multiple areas, while larger models can illuminate broader portions of the body at the same time.

3. Prepare the treatment area

Red and near infrared light work best when they have a relatively direct path to the skin. That usually means exposing the treatment area by moving or removing clothing that covers it.

It's also a good idea to begin with clean, dry skin. Heavy fabrics, thick lotions, or products containing ingredients that increase light sensitivity may not be appropriate in every situation. If you're unsure, follow your healthcare provider's advice or the guidance supplied with your skincare products.

4. Position yourself at the recommended distance

Treatment distance plays an indispensable role in how much light reaches your body. Standing closer increases light intensity over a smaller area, while moving farther away allows the light to spread across a wider treatment zone.

Many home panels recommend positioning yourself somewhere between 6 and 24 inches away, although that range varies by manufacturer. Rather than copying someone else's routine, use the distance recommended for your specific panel.

5. Choose the appropriate light setting

Many modern panels allow users to select red light, near infrared light, or both together. The appropriate setting depends on your panel and how you plan to use it.

Some homeowners prefer the convenience of using both wavelengths during the same session. For example, the NW Immersion Sauna Elite Near Infrared & Red Light Therapy Panel combines red and near infrared wavelengths in a sauna-rated design. It allows users to incorporate both into a single routine. Regardless of the panel you own, it's best to begin with the settings recommended by the manufacturer.

6. Set the timer before you begin

Most home sessions are relatively short, often lasting around 10 to 20 minutes, determined by the device and treatment area. Setting the timer before you begin makes it easy to stay within the recommended treatment window.

Keep in mind that spending more time in front of the panel isn't automatically better. Following the recommended session length is a more effective approach than extending treatments simply because you have extra time.

7. Face the panel comfortably

Position yourself so the intended treatment area faces the panel as directly as possible. Depending on the installation, you may be standing, sitting, or lying down during the session.

There's no need to remain perfectly still. Small, natural movements are fine as long as you stay close to the recommended treatment distance and keep the intended area within the panel's coverage.

8. Reposition if you're treating multiple areas

If you're using a tabletop or partial-body panel, you may need to turn around or adjust your position to expose another part of the body. This is perfectly normal and often more practical than moving the panel itself.

Rather than rushing through several body areas in one long session, follow the manufacturer's guidance for treatment duration and reposition only when necessary.

9. Finish the session and stay consistent

Once your timer ends, turn off the panel and continue with the rest of your routine. Some people head into a sauna, others stretch, exercise, or simply move on with their day.

Consistency matters more than occasional marathon sessions. A routine that's realistic enough to maintain over the long term is far more valuable than one that's difficult to repeat.

How Long Should You Use a Red Light Therapy Panel?

Most home red light therapy sessions last somewhere between 10 and 20 minutes, but there isn't a single session length that applies to every device. The ideal duration is contingent on factors such as the panel's power output, treatment distance, and the manufacturer's recommendations.

Instead of choosing an arbitrary amount of time, consider the factors below.

Your panel's power output matters

Panels differ in irradiance, which refers to the amount of light energy reaching the treatment area at a given distance. Higher-output panels may deliver similar exposure in less time than lower-powered models.

That's one reason why copying someone else's routine isn't always appropriate. Two panels can look similar while producing different levels of light intensity.

Treatment distance changes exposure

The farther you stand from the panel, the larger the area it can cover, but the light reaching your body also becomes less concentrated. Standing closer increases intensity across a smaller area.

Distance and session length work together. If the manufacturer recommends a specific combination of both, it's best to follow that guidance instead of adjusting one without considering the other.

Longer sessions don’t mean better

It's easy to assume that doubling your session will double the benefits, but that's not how red light therapy works. Current photobiomodulation research does not suggest that simply increasing exposure indefinitely produces better outcomes.

For most people, the better approach is following the recommended treatment time consistently rather than extending every session beyond what the manufacturer advises.

How Often Should You Use Red Light Therapy?

The ideal frequency depends on your device, your routine, and your intended use. Some manufacturers support daily sessions, while others recommend using their panels several times each week.

You don’t need to focus on doing as many sessions as possible. Concentrate on building a routine you can comfortably maintain.

Start conservatively

If you're new to red light therapy, begin with the lower end of the recommended session duration and frequency. This gives you an opportunity to become familiar with the panel before increasing use within the manufacturer's guidelines.

A gradual approach also makes it easier to establish a routine that fits naturally into your schedule.

Consistency beats marathon sessions

A 15-minute session you complete several times each week is more practical than an occasional hour-long session that becomes burdensome to repeat.

Building consistency into your routine also makes it easier to monitor how you're using the panel without constantly changing your schedule or treatment settings.

Follow professional guidance when appropriate

If you're using red light therapy alongside care for a diagnosed medical condition, injury, or skin concern, follow the treatment plan provided by your healthcare professional.

Consumer wellness devices should complement professional care and are not intended to replace it.

When Is the Best Time to Use Red Light Panels?

There isn't one universal time that's best for everyone. As mentioned, the right time is the one that fits naturally into your daily schedule while matching the manufacturer's recommendations for your device.

Many people incorporate red light therapy into an existing wellness routine.

Before or after a workout

Some active individuals prefer using a red light panel before training, and there are those who include it after exercise as part of their recovery routine. Both approaches are common, and the choice comes down to personal preference and overall scheduling.

Before or after a sauna session

Red light therapy can also be paired with sauna use. Some homeowners complete a session immediately before entering the sauna, while others prefer using the panel after their heat session.

If your goal is to install a panel inside the sauna itself, however, make sure it's specifically designed and rated for sauna use. Standard indoor panels are not necessarily built to operate in high-temperature environments.

After a cold plunge

Some people finish their recovery routine after cold exposure. Others prefer placing it elsewhere in their schedule. There's no universally correct sequence, and many routines work well when used consistently. 

As with other recovery practices - comfort, consistency, and following the manufacturer's instructions matter more than chasing a perfect protocol.

During a morning or evening routine

For many homeowners, the easiest time to use a red light panel is simply whenever it fits naturally into their day. A morning session may become part of a pre-work routine, while an evening session can fit comfortably into a post-work wind-down.

What Should You Wear During Red Light Therapy?

For most sessions, the treatment area should be uncovered so the light can reach the skin directly. Clothing, towels, and thick fabrics can reduce the amount of light reaching the intended area.

That doesn't mean you need to be fully undressed. Simply expose the area you're treating while wearing whatever keeps you comfortable. If you're working on your shoulders, for example, a tank top may be enough. If you're targeting your knees, rolling up your pants may do the trick.

Do You Need Eye Protection When Using a Red Light Panel?

Eye protection depends on the panel you're using. Some manufacturers recommend protective eyewear, particularly with higher-output devices or when the face is being treated, while others provide different guidance based on their specific design.

Even when protective glasses aren't required, you shouldn't stare directly into illuminated LEDs for extended periods.

Can You Use a Red Light Panel Inside a Sauna?

Yes, but only if the panel is specifically designed and rated for sauna use.

This is one of the biggest misconceptions surrounding red light therapy. A panel that works perfectly in a home gym or spare bedroom may not be able to withstand the sustained temperatures inside a traditional sauna. 

Before installing any device, verify its maximum operating temperature and follow the manufacturer's installation instructions.

Who Should Talk to a Healthcare Provider Before Using Red Light Therapy?

Red light therapy is considered low risk when used according to the manufacturer's instructions. Even so, certain individuals should speak with their healthcare provider before beginning a new routine.

That conversation is especially worthwhile if you:

• Take medications that increase light sensitivity

• Have a condition associated with photosensitivity

• Have significant eye conditions

• Are pregnant

• Plan to use red light therapy alongside treatment for a diagnosed medical condition

• Experience unusual discomfort or skin reactions during use
