Benefits of light therapy on brain health

The brain is one of the hardest working organs in the body and is made up of many parts, each with a specific and important function. It controls our ability to balance, walk, talk, and eat. It coordinates and regulates our breathing, blood circulation, and heart rate. It is responsible for our ability to speak, to process and remember information, make decisions, and feel emotions. Every brain is unique, ever-changing, and extremely sensitive to its environment.

When the brain is healthy, it functions quickly and automatically. But when problems occur, the results can be devastating.

Brain disease affects 1 in 6 people worldwide and includes a wide spectrum of diseases and disorders – from stroke and Alzheimer’s disease to multiple sclerosis, epilepsy, traumatic brain injury, depression, and more. 

Brain disorders are one of the toughest health challenges as many of these disorders are highly debilitating and have no cure. Others can be managed but still have wide-ranging effects on the quality of life of patients and their carers.

How light therapy can support brain health

Research into utilizing light therapy for brain health is growing rapidly and has shown promising benefits.

A 2021 study conducted by researchers from the United States, South Africa, Iran, and Germany showed that light therapy by which red and near-infrared light is delivered to the scalp to stimulate neural cells and brain function, has a positive effect on brain health.   The outcome of this study, which was also published in the Journal of Alzheimer’s Disease, mentions that light therapy is safe, simple, pain-free, easy to administer, and well-tolerated by the patients.

Our light therapy helmet (HLM001) uses 1070nm LEDs which penetrate human tissues well, even penetrating the human skull where it has a beneficial effect in the brain.   The cognitive and memory impairment can be ameliorated by using this 1070nm wavelength (color) as well as the behavioral deficits associated with these neurological conditions.   Using light therapy has also neuroprotective effects, slowing the underlying death of neurons and promoting regeneration. 

There is plenty of evidence suggesting the efficacy of light therapy in three major types of brain conditions:

  • Traumatic events (stroke, global ischemia, and traumatic brain injury)
  • Degenerative diseases (dementia, Alzheimer’s and Parkinson’s diseases)
  • Neuropsychiatric disorders (major depression, bipolar disorder, anxiety, and post-traumatic stress disorder).

In recent years, light therapy is also used as a brain-boosting strategy in healthy young and old individuals. There is also evidence of changes occurring at the neurobehavioral level such as cognitive improvement (in various domains, e.g., learning and memory, executive function, concentration, and attention), antidepressant-like effects, and improved sleep quality.
