What Are the Benefits of Red Light Therapy?

Red light therapy is a treatment that uses red light on the skin to increase oxygen to the cells. It is non-invasive, and does not hurt and has proven to have healing and recovery benefits to support things like skin, muscles and tissue repair.

At The Good Practice, patients can access advanced red light therapy under professional medical supervision. Sessions last around 20 minutes, with patients able to remain fully clothed while relaxing under the light. For more information, visit red light therapy near me.

Red light therapy is also known as photobiomodulation, which is the process of exposing the body to specific wavelengths of light. The light is absorbed by cells and may help support the body's natural repair processes. Unlike ultraviolet light, it does not involve UV exposure or burning.

What are the main benefits of red light therapy?

Red light therapy is being explored for a growing range of health, recovery and wellbeing goals. Research is still developing and results can vary depending on the condition being treated and the type of light therapy used including:

• Supporting muscle recovery
• Reducing pain and inflammation
• Supporting skin health
• Supporting tissue repair
• Promoting relaxation and wellbeing
• Supporting energy and cellular function

‍

Red light therapy to support muscle recovery

Red light therapy has become increasingly popular among athletes and people who exercise regularly.

Photobiomodulation may support recovery following physical activity by influencing cellular energy production and inflammatory processes. This could make it useful alongside other recovery approaches such as exercise, stretching, massage and cryotherapy.

A 2025 systematic review specifically examining whole-body photobiomodulation found evidence of potential benefits for exercise performance and recovery, although the researchers highlighted the need for further high-quality research.

‍

Red light therapy to reducing pain and inflammation

Another reason people explore red light therapy is to support the management of pain and inflammation.

Research suggests that photobiomodulation may influence inflammatory pathways and pain signalling. A 2026 systematic review of 14 studies found that most included trials reported significant pain reductions, particularly among people with conditions such as fibromyalgia and peripheral neuropathy. However, the researchers also noted that treatment protocols varied considerably.

This means red light therapy may have a role as part of a wider approach to managing discomfort, rather than being considered a standalone treatment.

‍

Red light therapy to support skin health

Red light therapy is also widely used for skin health and cosmetic purposes.

It may support collagen production, skin texture and the appearance of fine lines and wrinkles. It has also been investigated for conditions including acne and inflammatory skin concerns.

An earlier systematic review looked at 31 randomised controlled trials involving LED treatments in dermatology. The researchers found encouraging evidence for some applications, although they also highlighted differences between studies and the need for further research.

‍

Red light therapy to support tissue repair

Red light therapy may also support the body's natural repair processes.

The underlying theory is that specific wavelengths of light can interact with cells and mitochondria, potentially supporting energy production and cellular function. This is one reason red light therapy is being investigated for areas such as wound healing and soft tissue recovery.

However, the evidence is not equally strong for every use. Research continues to establish which conditions are most likely to benefit and which treatment protocols are most effective.

‍

Red light therapy to promote wellbeing and relaxation

For some people, red light therapy is simply a way to take time out and support their general wellbeing.

The treatment is non-invasive and painless. At The Good Practice, patients lie comfortably under the light for around 20 minutes, with the treatment taking place at a comfortable temperature.

Some people may notice changes in how they feel after several sessions, but longer-term benefits often require consistent use.

‍

Can red light therapy be used for professional athletes?

Yes. Red light therapy is increasingly being explored by professional athletes as part of a wider approach to training and recovery including:

• Footballers
• Rugby players
• Marathon runners
• Weightlifters
• Swimmers
• Gymnasts
• Mixed martial arts and cage fighters

Photobiomodulation may help support muscle recovery, reduce exercise-related soreness and support physical performance. 

Some athletes use it alongside physiotherapy, stretching, massage, nutrition and adequate rest. 

The results can vary depending on the wavelength, dose and treatment schedule, so red light therapy should be viewed as a complementary option rather than a replacement for sports medicine or rehabilitation.

‍

Can red light therapy be used to treat headaches and migraines?

Yes, There is growing interest in using light-based therapies to help people with headaches and migraines, although the evidence is still developing.

 Importantly, red light is different from the bright or blue light that can trigger symptoms for some people with migraine. 

Research suggests that certain wavelengths may influence pain pathways and inflammation, potentially making it useful as a complementary treatment for some people. 

‍

Is red light therapy right for me?

Red light therapy can be considered as part of a wider approach to health, recovery and wellbeing. It may be particularly appealing to people who want to explore non-invasive options alongside exercise, physiotherapy or other treatments.

At The Good Practice, treatment is provided under professional medical supervision, giving patients the opportunity to discuss whether red light therapy is suitable for their individual needs.

As with any treatment, red light therapy is not suitable for everyone. If you have an underlying medical condition, take medication that increases light sensitivity or are pregnant, it is sensible to speak to a healthcare professional before starting treatment.
