It pays to take note of Uncle Jack. I am still not ready to go as far as he is regarding the lighting issue, but I am sure it is hugely important.
I know too well how much can be done with a Whole Foods, Plant-Based diet, and I am fully convinced that it should be the first 60% of any therapy for diabetes, heart disease, cancer and other chronic illnesses. In some cases it is 100%. But this lighting thing is insidious, and I have changed my life around it. I take a walk every morning at dawn, and it is a better way to start the day.
The bottom line is that all the artificial lighting screws up our internal clock, and at least getting started right helps you counter some of that.
I am also involved with a healthy lighting product, Pure-Light, which has a light activated Titanium DiOxide coating, which emits super-oxides that will deal with any airborne pollutants of a chemical or biological nature. In indoor pollution, normal air filters deal with mostly particulate matter, but not with chemical or biological agents. This lighting does. In environments that want to be kept sterile, like medical facilities, there is also a sister product, Sani-coat, which can be used on flat surfaces, like walls and ceilings, and again, it is also light activated. HAI, Hospital Acquired Infections could be a thing of the past. Contact me at DaBx Demand Side Solutions.
In general, in bedrooms, bathrooms and kitchens and anywhere where smell is an issue, Pure-light is an easy solution. The light also produces hardly any blue light, but predominantly red. Worthy of consideration.
