Can Red Light Therapy improve memory?

Red light therapy may offer benefits for improving memory through its effects on neuronal function. Andrew Huberman explains that red light and near-infrared light can reverse the aging process in neurons, specifically highlighting its positive impact on retinal neurons which are part of the central nervous system. These therapies could potentially be extended to other neurons in the brain, including those involved in memory, by improving mitochondrial function and reducing reactive oxygen species 1.

Moreover, Huberman notes that while the current studies mainly focus on vision, the mechanisms by which red light improves neuron health—like reducing reactive oxygen species and lipid deposits—could theoretically benefit neurons related to memory as well 1.

Although more targeted research is needed to conclude definitively, the promising outcomes in neuronal health suggest red light therapy could indeed support memory improvement.
