Is Your Lighting Making You Sick?
Humans have long created artificial lights by burning or heating materials, however lighting systems today are far more invasive to the human body than those of the past. According to a new study reported in the Cell Press journal, many negative health consequences result from constant exposure to artificial light
All life evolved with the electromagnetic frequencies from the sun and the earth, and these frequencies are considered essential to all life. Life itself synchronizes and harmonizes with these frequencies. But what happens when these frequencies are disrupted by modern technology?
With the growing use of energy saving lamps and the development of new lighting technologies, comes the long-term concern that some people who have conditions that react to light might be negatively affected by this shift.
Previous research by Northwestern scientists showed that people who received the majority of their bright light in the morning weighed less than those who were exposed to most of their bright light after 12 p.m. The researchers wanted to understand why. Mouse studies also have shown that mice kept in constant light have altered glucose metabolism and gain weight compared to control mice.
“Our study shows that the environmental light-dark cycle is important for health,” says Johanna Meijer of Leiden University Medical Center in the Netherlands. “We showed that the absence of environmental rhythms leads to severe disruption of a wide variety of health parameters.”
Those parameters included pro-inflammatory activation of the immune system, muscle loss, and early signs of osteoporosis. The researchers say that the observed physiological changes were all indicative of “frailty” as is typically seen in people or animals as they age. But there was some more encouraging news, too.
“The good news is that we subsequently showed that these negative effects on health are reversible when the environmental light-dark cycle is restored,” Meijer says.
