Infrared Light and Parkinson's Disease: Is there a connection?

Updated: Dec 30, 2019

Parkinson’s Disease is a progressive nervous system disorder that affects neurons in the brain and their ability to regulate dopamine. This can cause difficulties with muscle rigidity, speech, mobility, tremors, and many other areas of functioning. While there are medications that can help, there is currently no cure for Parkinson’s.

The disease usually progresses as mobility and speech become further impaired.

However, there has been some interesting research into treating Parkinson’s with infrared light. Multiple researchers have found beneficial effects of Near Infrared (NIR) light for the treatment of Parkinson’s (Liang et al., 2008; Whelan et al., 2008; Ying et al., 2008; Shaw et al., 2010; Peoples et al., 2012; Moro et al., 2013, 2014; Vos et al., 2013;; Darlot et al., 2015; El Massri et al., 2015).

These studies found that NIR is neuroprotective (meaning it can protect neurons in the brain from potential damage). However, many of these studies involved intercranial NIR, meaning that surgery was performed to allow NIR to penetrate the cranium or skull. However, a recent study by Stone et al (2013) found that even using light on the body and excluding the head produced neuroprotective factors (protection for neurons in the brain from disease), leading them to believe that the immune system is also involved in the benefits of NIR for Parkinson’s. Researchers also found that there were no side effects for patients receiving the NIR.

Additionally there has been some research on transcranial NIR applied with a helmet by the QuietMind Foundation that has anecdotally shown improvement for a patient – see the video HERE. While more research is needed, the current studies are promising and could indicate that near infrared light is a treatment option for those suffering from Parkinson’s. While we are waiting for more human trials, The Salt Oasis Kingsport offers infrared lamp and sauna therapy that may be helpful for many conditions.
