As an infra red lamp user, I was interested to read Katherine Fletcher’s blog post about the therapeutic uses of light on the Parkinson’s UK website. The data are limited, but Katherine thought some lines of inquiry look promising.

She poses the question of how light can have an effect on the dark recesses of the brain and it reminded me of a paradox investigated by Dr Lyall Watson in his 1973 book Supernature. In this instance, mussels were moved inland and re-established a response to tides that would have been recorded, had the laboratory been located at sea level.

These captive bivalves all had a capacity to resynchronise in some way with the moon’s gravitational field, opening and closing in unison within a closed tank. It was another instance of a measurable response with no obvious explanation.

Katherine’s overview of light therapies and Parkinson’s is on the Parkinson’s UK website at: www.medium.com/parkinsons-uk/shedding-light-on-parkinsons-the-potential-for-light-therapy
