Human Centric Lighting Technology and its impact on
Parkinson patients

 

It has been a vigorous discussion about the impact of human
centric lighting as a medical treatment for Parkinson victims. Supporters and many
Parkinson patients hold strong belief on positive results harvested from
experimenting suitable wavelengths of lighting. On the other hand, sceptics
believes more on placebo effect of lighting solution than its actual impact on Parkinson
patients’ nerves and require more evidence-based research to apply the lighting
technology onto human beings since most of the official clinical experiments have
been implemented on animals such as mice or monkeys.

Parkinson is known for its for its tremor, impaired balance,
muscle rigidity, poor sleep, memory loss and depression. It is believed to
associate with dopamine depletion and loss of neurons on the basal ganglia
region of the brain. Unfortunately, the mainstream medication and therapy
mainly solves symptoms such as dopamine increase yet wearing off with time,
rather than the decease itself.

While Parkinson cause still remains mystery, effort is made
by Parkinson victims themselves on finding a new effective method such as Max
Burr, a federal Liberal MP. Parkinson has tremendous negative effect on his political
career such as loss sense of balance, timid voice. Max found out about photobiomodulation
and decided to take the shield and fight against Parkinson himself. Photobiomodulation is the method of
using lighting technology to modulate key biological processes at a cellular or
generic level. Different light
colours impacts differently on human body.

o  
Blue: boost alertness and performance,
suppresses production of melatonin, increases appetite

o  
Yellow: exposure during the day contributes to
better sleep at night

o  
Red: against depression, excites the brain

o  
Red and green: enhances mobility (Parkinson
patients)

From that, usage of 670-nanometre intra red light protected
the neurons in Parkinson’s – published by Professor John Mitrofanis from Sydney
University. Photobiomodulation was mostly proceeded and showed effect on
Parkinson animal. Nevertheless, there have been 9 human cases going through the
experiment with improvements were recorded and published by peer-reviewed medical
journals. That said, lighting technology for Parkinson is more of “off-label”
prescribing as clinicians are cautious about regulations. However, it is
undeniable that lighting solution gives Parkinson victims a brighter future. A
good news for this innovative lighting solution is that it causes no
side-effect. This is also the aspiration for lighting technology companies to
develop light therapy device for demands.

Even though lighting therapy stills requires major
investments for more human trial before becoming a mainstream therapy for
Parkinson, the attention has been drawn to the positive effect of victims after
receiving lighting treatment. For now, small amount of human studies, positive
effect of photobiomodulation on human mood, productivity, dopamine stimulation
might open venue for more research and investment in lighting technology in
next decades.
