It’s not just the heat of a room that’s causing your pain, according to new research from the University of California, San Francisco.
Researchers at the university’s Institute of Photobiomaterials and Photonics have discovered that light therapy lighting can cause phototoxicity, which means the light causes the cells to die.
The study, published in the Journal of Photochemistry and Photobiology A, analyzed light therapy luminescent light (LTl), a form of light therapy, from different manufacturers and found that the LTl from companies like LUX, Bright Lights, and Blue Sky was the most toxic.
The researchers found that LTl emitted more harmful radiation than any other type of light treatment, which was a major concern to the researchers.
“Our studies showed that light can cause cancer cells to go into overdrive and destroy cells, which could lead to cancer,” lead researcher and PhD student Joshua Bekoff told The Hill.
“But what this study shows is that LTlc is not necessarily bad, it’s good.”
The researchers tested different types of LTl that emit a range of wavelengths from white to red and found all of them caused the cells in the lab to die at levels more than three times higher than that of the control group.
They also found that when they combined light therapy with light therapy to create a dark room, LTl released more harmful ultraviolet radiation than when they used the light therapy alone.
This finding suggests that light could be used to treat cancers that would otherwise be hard to treat with conventional treatments.
The authors point out that LTlifes are only one of several types of light treatments available and that there is no one best light therapy.
The scientists also point out there are other treatments for phototoxic diseases, such as laser therapy and laser phototherapy, which use infrared light.
“I’m not saying that light should be used exclusively as a cancer treatment, but it should be the first line of defense,” Bekonoff said.
“This study is one of the most significant, but also the most limited, of its kind.
It’s a very good first step, but we don’t yet have the tools to determine the effects of light on other types of phototoxins.”
The study was supported by the National Institutes of Health and the National Science Foundation.
