Endorphins. Without arguing those points, I want to say that some of the health impacts of managing artificial light are related to improved production of Melatonin and its antioxidant role in fighting disease. When atmospheric scientists first called attention to possible chemical destruction of the stratospheric ozone layer in the early 1970s, one predicted consequence of the increased UVB radiation was a rise in skin cancer rates, especially in Australia, New Zealand, South Africa, and Latin America. While the role melatonin plays in our health is still not fully understood, studies suggest that without a good dose of daily sun exposure, we do not produce optimal levels of melatonin.

These days, most experts define vitamin D deficiency as a serum 25(OH)D level of less than 20 ng/mL. The endogenous rhythm of secretion is generated by the suprachiasmatic nuclei and entrained to the light/dark cycle. Light can effect on circadian rhythms through changing in melatonin and circadian rhythms and may have significant effect on sleep-wake cycle (17, 18). Without the sunscreen, this same individual would be incurring substantially more damage to her skin but not further increasing her vitamin D level, she says. To determine the potential link betwen sun exposure and the protective effect in preventing hypertension, Rolfdieter Krause of the Free University of Berlin Department of Natural Medicine and colleagues exposed a group of hypertensive adults to a tanning bed that emitted full-spectrum UVR similar to summer sunlight. Populations at higher latitudes have a higher incidence and prevalence of MS; a review in the December 2002 issue of Toxicology by epidemiology professor Anne-Louise Ponsonby and colleagues from The Australian National University revealed that living at a latitude above 37 increased the risk of developing MS throughout life by greater than 100%. Accessibility John. Dr. Merrys in-depth article about blue light blocking glasses cites 26 scientific papers and reviews 8 popular claims about improved sleep and other health effects. Many studies have shown that cancer-related death rates decline as one moves toward the lower latitudes (between 37N and 37S), and that the levels of ambient UVR in different municipalities correlate inversely with cancer death rates there. More recently, there has been a growing appreciation for vitamin Ds impact on bone health in adults. The light deprivation is one of the causes for disturbance in circadian rhythm (11). Belkins WeMo Smart LED Bulbs and home automation kit uses your Wi-Fi home network and allows you to control, schedule and dim your lights from anywhere. Sunlight has other benefits as well.

It was also recognized that wintertime sunlight in the temperate zone was too feeble to prevent rickets. As it's synchronized with the sun, melatonin helps keep your circadian rhythm regular so you get consistent, quality rest. Normally produced during the day, serotonin is only converted to melatonin in darkness.
