Psychological benefits

Several studies published on the US National Institute of Medicine also have shown results reflecting the psychological benefits of infrared light therapy, stating that there were improvements of symptoms in patience with dementia and Alzheimer’s and a significant improvement in the conditions of patience with depression.

Red light therapy is an increasingly popular alternative therapy to healing and skincare though academics and medical professionals do warn that although RLT are generally considered safe with no reported significant effects or risks, it is still a relatively new treatment with limited clinical studies therefore the majority of beneficial claims of the treatments are anecdotal and based on personal experience.
