What are the potential benefits of red light therapy for children?Updated 7 months ago

Author: Kristal Kellock

Red light therapy (RLT), also known as photobiomodulation, involves the use of specific wavelengths of red and near-infrared (NIR) light applied to the skin. These wavelengths can penetrate biological tissues and are being studied for their potential to support cellular function. The primary mechanism proposed in research is the stimulation of mitochondrial activity, leading to increased production of adenosine triphosphate (ATP)—the energy currency of cells.

In the brain, this process is being explored for its possible influence on neuroplasticity, inflammation modulation, and neuronal energy dynamics. These are areas of interest in child development and learning. While the field is still developing, emerging studies and case reports suggest that RLT may hold promise as a supportive intervention for various paediatric challenges. This article explores those areas of interest while remaining within a research-based and evidence-informed framework.

Red Light Therapy and Paediatric Brain Health:

Some preliminary studies suggest that RLT may support certain brain functions such as attention, memory, and emotional regulation. For children with learning differences, including conditions like autism spectrum disorder (ASD) or attention-deficit hyperactivity disorder (ADHD), these findings have opened up new areas for investigation.

For instance, a 2022 case study explored daily RLT applied to the frontal lobe over 12 weeks in children aged 7–12 with ADHD. Outcomes included observed improvements in attention, reduced impulsivity, and improved emotional regulation. Parents and educators also reported changes in classroom engagement. Neuroimaging data showed changes in prefrontal cortex activity—an area commonly linked to focus and executive function.

A 2021 pilot study on children with ASD (aged 5–10) examined RLT’s potential to support social engagement and sensory processing. Caregivers reported calmer behaviour and better communication in some children. EEG data indicated changes in brainwave patterns, although larger studies are needed to validate these observations.

Similarly, a 2020 study focused on children with speech and language delays found that after six weeks of RLT, participants showed gains in both receptive and expressive language skills. Increased responsiveness during therapy and improvements in word recall were reported.

Proposed Biological Mechanisms (Under Study):

The possible effects of RLT on the developing brain are likely due to its influence on several cellular and physiological processes:

Increased Mitochondrial Activity: RLT may enhance ATP production, which could support cellular function in the brain. This is especially important for energy-intensive processes like learning and development.

Neuroplasticity: Some studies suggest RLT may facilitate new neural connections, relevant for cognitive flexibility and memory.

Oxidative Stress and Inflammation: Early findings suggest RLT might help modulate inflammatory responses and oxidative stress, factors which are often heightened in neurodevelopmental conditions.

Blood Flow and Oxygenation: Improved circulation and oxygen supply to the brain may contribute to general neural support.

Sensory and Motor Processing: There is growing interest in whether RLT could influence sensory integration and motor skills development through its effects on nerve cells and muscular coordination.

Sleep Support: Given its potential role in modulating circadian rhythms, RLT is being studied for its effects on sleep—an important factor in memory consolidation and emotional resilience.

Emotional Regulation: Research is investigating whether RLT has an impact on neurotransmitter activity, including serotonin and dopamine, which may influence mood and stress responses.

The Role of the CERA System and the Gut-Brain Connection:

CeraThrive’s CERA System is an example of an innovative RLT device designed to support the body’s gut-brain communication pathways. It features a dual-application system—a headband and a body panel, delivering four wavelengths (630nm, 850nm, 940nm, 1070nm) via pre-programmed 10-minute sessions available through a dedicated mobile app.

While no claims are made regarding paediatric use or the treatment of specific conditions, the design of the system is informed by a growing body of research into the gut-brain axis—a key area of interest in both neurological development and systemic health. CeraThrive continues to explore how red and near-infrared light may support foundational physiological balance, particularly through the modulation of the gut-brain connection.

In Summary:

Red light therapy is an exciting and emerging field in paediatric neuroscience and developmental support. While early findings are promising, especially in areas like attention, language, and sensory integration, more research is needed to determine its full potential and safe use in children. Parents and clinicians interested in exploring RLT are encouraged to follow developments in this field, work with experienced practitioners, and always consider the latest peer-reviewed evidence.
