Red and infrared light therapy has been studied for its potential to enhance cognitive function, and the findings suggest several mechanisms through which this therapy could positively impact brain performance. Here’s how and why red and infrared light can enhance cognitive function:

1. Improved Cerebral Blood Flow:
   • Red and infrared light therapy, particularly in the 650nm and 810nm wavelengths, can penetrate the scalp and skull to reach brain tissues. This light energy stimulates vasodilation, or the widening of blood vessels, which enhances blood circulation in the brain. Improved blood flow means that more oxygen and essential nutrients are delivered to brain cells, supporting their function and improving cognitive performance.
2. Increased Cellular Energy Production (ATP):
   • Light therapy stimulates the mitochondria in brain cells, which are the powerhouses of the cell responsible for producing adenosine triphosphate (ATP). ATP is the energy currency of cells, and increased ATP production boosts cellular activity and repair processes. This heightened cellular energy is associated with better cognitive function, including memory, attention, and processing speed.
3. Reduction of Inflammation and Oxidative Stress:
   • Chronic inflammation and oxidative stress in the brain are linked to cognitive decline and neurodegenerative diseases like Alzheimer’s. Red and infrared light therapy has anti-inflammatory properties and helps reduce oxidative stress by promoting the production of antioxidants. This protective effect helps maintain brain health and cognitive function over time.
4. Neuroprotection and Neural Repair:
   • Red and infrared light therapy has been shown to promote neurogenesis, the growth and repair of neurons, particularly in areas of the brain associated with learning and memory, such as the hippocampus. The therapy also supports synaptogenesis, the formation of new synaptic connections between neurons, which is crucial for cognitive processing and memory formation.
5. Enhanced Brain Plasticity:
   • Brain plasticity, or neuroplasticity, refers to the brain’s ability to adapt and reorganize itself by forming new neural connections. This is essential for learning, memory, and overall cognitive function. Studies suggest that light therapy can enhance neuroplasticity by promoting the expression of brain-derived neurotrophic factor (BDNF), a protein that supports the survival and growth of neurons.

Supporting Studies:

• A study published in the Journal of Alzheimer’s Disease (2017) demonstrated that transcranial infrared light therapy could improve cognitive function in patients with dementia and mild cognitive impairment. Participants showed improvements in memory, attention, and mood after consistent use of light therapy.
• Another study in Photomedicine and Laser Surgery (2013) found that near-infrared light therapy enhanced cerebral blood flow and cognitive function in healthy older adults. The study reported improvements in memory, executive function, and processing speed.

Conclusion:

Red and infrared light therapy offers a promising, non-invasive approach to enhancing cognitive function. By improving blood flow to the brain, boosting cellular energy, reducing inflammation, and promoting neural repair, this therapy can support better memory, attention, and overall brain performance. The ONE by JBA Red and Infrared Light Cap leverages these benefits, making it a valuable tool for anyone looking to maintain or improve their cognitive function as part of their daily routine.
