What Is Red Light Therapy?

 

Red Light Therapy, also known as low-level laser therapy (LLLT), uses low energy light emitting diodes (LEDs) to stimulate cell function. The Red light penetrates the skin to a depth of 8-10mm. Once absorbed, the light energy is converted to cellular energy. Certain wavelengths of light enhance the functioning of mitochondria, which takes in nutrients, breaks them down and creates energy molecules for the cell. This improves the functioning of the whole cell which results in kicking off a whole series of metabolic events such as, improved healing, the reduction of inflammation, enhanced production of collagen and elastin, increased circulation and the formation of new capillaries and increased activity in the lymph system.​

​

How Does Red Light Therapy Work?

 

Your cells require energy to perform virtually everything they do.

​

Within many of your cells are structures called mitochondria, which play an important role in producing cellular energy. Certain wavelengths of red and near-infrared light can interact with molecules involved in mitochondrial function and other cellular processes.

​

This interaction is one of the mechanisms researchers continue to investigate when studying photobiomodulation and its potential effects on tissue function, recovery, inflammation, and skin health.

​

You don't need to understand the cellular science to enjoy a session, though. For you, Red Light Therapy simply means relaxing while your body is exposed to controlled wavelengths of light for a designated period of time.

​

Why Do People Choose Red Light Therapy?

 

One reason Red Light Therapy has become increasingly popular is its versatility.

​

People with very different wellness goals can incorporate photobiomodulation into their routines. Depending on the equipment being used and your individual goals, Red Light Therapy may be used to support:

• Exercise and muscle recovery

• Healthy-looking skin

• An active lifestyle

• Physical performance and wellness routines

• Tissue recovery following physical activity

• Overall wellness and self-care

 

Research into photobiomodulation continues to evolve, and outcomes depend on factors such as wavelength, intensity, treatment duration, frequency, the equipment used, and the individual.

​

Red Light Therapy should complement—not replace—appropriate medical care for an injury, health condition, or persistent symptoms.

​

Red Light Therapy for Active Lifestyles and Recovery

 

Exercise creates stress within the body. That's part of how we adapt, grow stronger, and improve physical performance—but recovery matters too.

​

Red and near-infrared light have been studied for their potential roles in muscle performance and recovery surrounding physical activity.

​

For active individuals, Red Light Therapy can be incorporated alongside appropriate exercise, nutrition, hydration, sleep, mobility work, and other recovery strategies.

​

You don't have to be an athlete to prioritize recovery, either. Work, recreational activities, exercise, and the physical demands of everyday life all place stress on the body.

​

Making recovery part of your routine can help you continue doing the things you enjoy.

​

Red Light Therapy for Skin Wellness

​

Red Light Therapy has also become popular as part of skin-focused wellness routines.

Research has explored photobiomodulation for its potential effects on cellular processes associated with skin health, including collagen production and tissue function.

​

For individuals interested in maintaining healthy-looking skin, Red Light Therapy provides a non-invasive option that can be incorporated into a broader skincare and wellness routine.

​

Because results vary and different devices use different wavelengths and intensities, your MonroeWellness provider can explain what to expect from the system used during your sessions.

​

What Does Red Light Therapy Feel Like?

​​

Red Light Therapy is designed to be an easy, comfortable experience.

​

During your session, the targeted area is exposed to red and/or near-infrared light for a designated period of time.

​

You may notice warmth from the equipment or environment, but Red Light Therapy is different from an infrared sauna and is not designed to heat your body in the same way.

​

There's no workout to complete and no recovery period afterward. Simply get comfortable and let the light do the work.

​

Red Light Therapy vs. Infrared Sauna: What's the Difference?

 

Although both services use forms of light energy, Red Light Therapy and infrared sauna sessions are different experiences.

​

An infrared sauna primarily uses infrared energy to generate heat and increase body temperature, creating the familiar sauna experience and encouraging perspiration.

​

Red Light Therapy uses specific wavelengths of light as part of photobiomodulation. Its purpose is not to make you sweat or substantially increase your body temperature.

​

Depending on your wellness goals, the two services may complement one another as part of a broader wellness routine.

​

Who Should Not Use Red Light Therapy?

​

People who should not use Red Light Therapy include:

• Women who are pregnant 

• People with active cancer

• People with light sensitive medical conditions

​

Frequently Asked Questions

​

What is photobiomodulation?

 

Photobiomodulation is the term used to describe the biological effects produced when certain wavelengths of light interact with cells and tissues. Red Light Therapy is one application of photobiomodulation.

​

Does Red Light Therapy use UV light?

 

No. Red Light Therapy uses red and potentially near-infrared wavelengths rather than the ultraviolet radiation associated with sun exposure and tanning beds.

​

Does Red Light Therapy hurt?

​

Red Light Therapy is non-invasive and generally does not cause painful sensations during a session. Your experience may vary depending on the equipment and treatment protocol.

​

How long is a Red Light Therapy session?

​

Session times vary depending on the equipment, area being exposed, and treatment protocol. More is not necessarily better with photobiomodulation, so sessions should follow the recommendations for the specific equipment being used.

​

How many sessions should I schedule?

​

That depends on your goals and the equipment being used. Some people choose to incorporate Red Light Therapy into an ongoing wellness routine, while others may use it for a particular period of time. The MonroeWellness team can help you understand the options available.

​

Isn't this just another tanning bed?

​

No. Tanning beds primarily use ultraviolet radiation to stimulate changes in skin pigmentation. Red Light Therapy uses different wavelengths and is not intended to tan the skin.

​

Is Red Light Therapy appropriate for everyone?

 

While Red Light Therapy is non-invasive, individual health conditions, medications that increase sensitivity to light, eye considerations, and other factors may affect whether it is appropriate for you. Discuss relevant health information with your provider before beginning a new wellness service.
