Thank you, Thea.
Red light therapy has been shown in clinical studies to have a wide variety of therapeutic effects on the human body. The treatment is administered to bare skin via powerful light-emitting diode (LED) bulbs.
Light photons are absorbed into the skin and underlying tissue where they interact with mitochondria. For people suffering from Parkinson’s disease, red light therapy has potential to regenerate nerves, protect nerves from further damage, reduce inflammation, and stimulate healthy cell activity. These regenerative changes are shown to help with Parkinson's symptoms.
Lots of research to do but seems promising!
