Full Spectrum Light Can Help Prevent Cavities and Bone Loss

I was sitting at my computer the other day with aching eyes, wondering how I could be having issues with my eyes if I knew so much about natural health. It is always humbling to remember that I help a lot of people with their healing, but I still have so much to learn. So I started to do a little research, and found some very interesting information, not just about eye strain but also about tooth and bone loss which I would like to pass on to you.

I found that extensive research has shown that lack of natural daylight can impair our mood, health and well-being in a very dramatic way, and that our daily lives are greatly affected by the type of artificial illumination we use.

It seems like we spend most of our time indoors under artificial light at home or at work, and for the kids at school. Unfortunately, ordinary cool white fluorescent lamps, that most of us use (rather than full spectrum lighting found in some lamps and the sun) have an unbalanced spectral distribution and throw a depressing greenish yellow hue upon a room, distorting colors, stressing our eyes, creating a very unpleasant atmosphere, and may even cause cavities.
In recent years, full-spectrum lighting has been used in the treatment of seasonal affective disorder (SAD) through the use of “light boxes” that mimic natural sunlight, which we may not get enough of in some areas during the winter months. But can full spectrum lights actually prevent cavities from forming?

A nine-month long study of first grade children in windowless classrooms found that those under full-spectrum fluorescent lights had many fewer cavities in their newly formed permanent teeth than those under standard “cool white” fluorescent bulbs. It turned out that ten times as many children under cool white bulbs had new cavities. Many fewer cavities were also found when incandescent bulbs, which are higher in red and infrared, were used instead of full-spectrum fluorescent bulbs. The authors also found that a broad spectrum of ultraviolet, red and infrared light was important for the formation of teeth as well as resistance to decay.

Animal studies have confirmed this. Hamsters placed under cool white bulbs 12 hours per day for fifteen weeks had five times more cavities and ten times greater tooth loss per cavity (a total of 50 times greater tooth loss) than those hamsters placed under fluorescent bulbs with ultraviolet added to approximate natural sunlight.

Furthermore, the development of the male sexual organs was only one fifth as great in those hamsters under cool white light as compared to those under full spectrum light. Of course, this result correlates with our knowledge that testosterone, a steroid hormone, is dependent on Vitamin D for its synthesis, a vitamin that we get from sunlight.

It has also been found that the role of full-spectrum light benefits the eyes as well as when it strikes the skin. So now I knew why my eyes were feeling so stressed. I was indoors most of the time and in front of my computer.

The natural light received by the eyes plays a vital role in body chemistry. The light received by the eyes influences the hypothalamus, which in turn influences the pituitary and pineal glands. The pineal gland especially is involved in our diurnal rhythms, and our lack of quality light through the retina may be the source of many sleep disorders that are increasingly common among people who are always indoors.

A lot of research on this subject has been summarized by the German ophthalmologist Fritz Hollwich, MD, as well as by John Ott, Hon. D. Sci., a researcher on the properties of light. The array of bodily organs and systems that depend on full-spectrum light through the eyes is astounding. When the eyes are exposed to natural sunlight or full-spectrum light, the pituitary gland, thyroid gland, adrenal glands, ovaries, testes, pancreas, liver and kidneys all function better, according to the numerous studies. Which means, that if we are wearing sunglass or tinted eyeglass lenses, we are getting distortions in the light that enters the eyes which will in turn affect the endocrine system and many other body functions.

Full-spectrum light includes a balance of wavelengths from all colors of the visible spectrum plus ultraviolet and infrared. On the other hand, cool white fluorescent bulbs, which are now used for the great majority of interior commercial lighting, have strong yellow, but are very deficient in most of the other wavelengths, with no ultraviolet or infrared.

Unfortunately, however, UV light has received a bad name, primarily because of individuals who have a history of blistering sunburns followed by skin cancer. There has never been any research showing health benefits of blocking UV light to the eyes. However, it is now impossible to buy eyeglasses that allow full-spectrum light. All of the lenses made in the last ten years for eyeglasses are made to block UV light, even plastic lenses, which if untreated, would allow full-spectrum light. However, full-spectrum light to the eyes is necessary for proper functioning of ovaries, testes and thyroid, according to Hollwich and the research he summarizes.

Earl Staelin, writing in the current issue of the Well Being Journal, summarizes the recommendations of those who have studied light and its health effects, and recommends that individuals who must wear glasses try to get outdoors every day for 20 to 60 minutes or more without wearing any glasses. If the weather makes this impractical, then it would be beneficial to try to function without glasses indoors under full-spectrum lighting, because the amount of UV light that strikes the retina from around the edges of glasses is insignificant compared to the large amount of light coming through the eye and through the lenses. The full spectrum of daylight need not come from direct sunlight, but is available also on a cloudy day or under the shade of a tree or porch. Glass windows however, do block out UV light, so try to get out in the fresh air if at all possible.

 

For myself, I am installing full spectrum lighting in my home which will hopefully help my family with dental cavity issues, and for me for eye strain issues.

 

I’m sure you can do the research and find a good source for full spectrum lighting, but, here is where I am getting mine: http://www.fullspectrumsolutions.com/

 

Have a wonderful, happy, healthy winter season!

 

 

 

About Dr. Carolee Johnson N.D., M.H.

Carolee Johnson, N.D., M.H. has been practicing in the field of natural health since 1998. She holds a Doctorate in Naturopathy and a Bachelor of Science in Natural Health. She was trained as a Master Herbalist by the School of Natural Healing. She was trained in Holistic Iridology by Dr. David J. Pesek. Carolee also holds certifications in Sclerology, Lymphology, and Live Nutrition. She is a Certified Emotion Code Practitioner. Carolee has hosted several live food events with world renowned Russian born author and raw foodist Victoria Boutenko, and has taught many how to regain a good measure of health using hot and cold water, herbs and live nutrition. Thanks to Quantum Techniques she feels she can do a much more complete job in healing. My Personal Testimony: I struggled with my health nearly all my life. After giving birth to my last child, my health completely failed, and the future looked grim. I started working with natural healing after going to doctors and finding that they could do nothing for me. I cured myself of uternine turmors with herbs, live nutrition, hydrotherapy, clean air and sunshine. I also strengthened my ailing heart and kidneys the same way. However, I never regained my strenth and vitality until I met an angel straight out of heaven named Beth Daniel... and then my fortune changed! Quantum Techniques allowed me to find the underlying cause to the constant fatigue and the kidney and heart trouble that never would completely heal. When I came to Quantum Techniques for treatment, I was much too thin and still very weak. I had already tried everything else including other alternative methods and raw food. These natural methods were very helpful, but something was definitely missing. Being able to find the underlying causes made all the difference in regaining complete health and strength, and getting back to normal weight. I was also able to finally rest from the constant bouts of anxiety that had plagued me. Now instead of lying in bed feeling weak and miserable and scared, I enjoy hiking and swimming in natural hot springs with my husband and children, and running a cattle ranch on the desert's modern wild west along the old Pony Express Trail.
