So what does the right kind of LIGHT at the right time of day have to do with health? 

Nature's Way 
Because that was the way Nature designed us. We evolved for eons using the visible and non visible light of the sun which is the Natural electromagnetic spectrum with its enormous range of frequencies, bandwidths and wave lengths.  We are electric-chemical beings. Because we are mostly water and charged water at that, the sun is the battery charger for our mitochondria ("power plants" of the cells). Our mitochondria do more than just make ATP (energy) and metabolic water.  It is the environmental sensor gathered by light-sensing proteins in the eye and skin. They use the information from the light to program our body's processes such as the metabolic pathway,  DNA repair, hormone making, releasing, and suppression--circadian rhythm to name a few. 

Wrong light--Wrong signal--Spectrum of Light Matters 
It stands to reason that if we introduce a spectrum of light that is not prevalent--naturally--in the diurnal movement of the sun, then our biology is affected. All of the sun's visible and invisible light is matched to different processes in the body. We evolved that way.  At best, our body has coping strategies and will compensate for the many different stressors that bombard our organism.  But, when that mechanism goes beyond its capabilities to cope, a tipping point occurs and dis-ease will show up. Energy-saving lighting may save money in energy cost, but is it healthy? There are a lot of studies that show the color spectrum from LED and fluorescent light sources cause circadian disruption which cause disease.  Incandescent bulbs are hard to find, but in the scheme of things, they are a whole lot better for our health.  Moreover, taking this even further, there is research that shows that any light at night is disruptive to the body's fundamental processes. Hard to comprehend. Most of what effects us now, electric power, radio, tv and, for some, electronic devices have been a ubiquitous part of our life. Considering the timeline of evolution, artificial light is a very new. Can our evolutional body adapt at the speed that we are creating these technologies? Doesn't look like it.  If it could, what would that look like? Doubt we would even look the same!  With all of the other stressors in our life, is there any wonder as to why chronic diseases are so prevalent and are increasing in all ages?  

An Addiction? 
To reiterate, there is a lot of published research that shows the ill effects of blue light especially at night from our devices and lighting from blue emitting light sources.  Slowly this information is coming out, but not main-stream enough. Humans have become so addicted to our gadgets--computers, TV's, cell phones, tablets--that removing them or at least using protection when viewing them at night is not the norm--yet.  If we were zapped enough to feel the sting each time we used a device at the wrong time of day,  then maybe we would put them down.  But, the outcome of using devices at night, using blue spectrum emitting light sources--degrades our system so gradually that we, as consumers, cannot correlate the cause/effect.   

Blue light is a part of the electromagnetic spectrum and is essential to our circadian rhythms.  The sun delivers the correct dose at the right time. Overuse of blue-lit electronics and their use at night is a light-mismatch problem. Furthermore, electromagnetic pollution including our electrical power grid (ELFs-Extremely Low Frequencies) to microwaves are are fundamentally Light. Consider our brain operates on ELFs of1 Hz - 31.5 Hz and ponder whether the explosion of technology might be affecting humans, animals, insects, plants--all life. The truth is out there!  

Technology is part of our modern life and is not going away. Some things that can be done: 

At Home  
Expose the eyes to natural sunlight throughout the day but especially at sunrise and sunset.  The light information programs our cellular processes. 
* Change the intensity of light you are exposed and use incandescent bulbs, candle light.
* Exclude night use of devises. If you have to use the devices, install software like IRIS to change the color spectrum to red if used at night and use warm settings in the day.
* Use blue blocking glasses--not clear or yellow but orange, and at night, red lenses to eliminate all blue.  Blue light stops the release of melatonin--not what you want at night! Melatonin production and release is governed by diurnal light information gathered by the eye and skin sensors.

At Work 
if you work inside all day, especially in a home office, add a red light source to your daytime environment to balance the blue from the screen and supplement the light coming through the windows.  Daylight has both blue and red light.  Window glass filters out about 40% of the natural red light making the light predominately blue.  
* If working on computer or other devices, wear blue blocking glasses and cover your skin. Yes, even in the daytime.
* Take breaks.  Go outside.  If you wear glasses, take them off or let them rest down the nose to let light into the eyes. Bare the skin as much as possible.  Both the eyes and the skin have the photo receptors.

Electronic devices not only emit blue light, they have electric and magnetic fields and are receivers and transmitters of radio frequencies.  All of this is a form of non-native light.
