They are also typically quite high in EMFs. In other words, they selectively emit a fraction of the mitochondrial stimulating light band. This type of bulb produces less reliable “digital” monochromatic light. By contrast, far-infrared or “full-spectrum” saunas use red LED lights. Incidentally, this wavelength is exactly what is provided in a near-infrared sauna powdered by incandescent heat lamps. Each participant was given a small handheld flashlight that emitted a visible red light with a wavelength of 670 nanometers.Įach person spent a scant three minutes each day looking into the light over a period of two weeks. Researchers recruited 12 men and 12 women, with ages ranging from 28 to 72. Just a few minutes a day of exposure to red light can have a dramatic, rejuvenating effect on vision. Now, science is starting to provide some answers according to a study published in the peer-reviewed Journal of Gerontology. I was shocked as this was never something I expected when I began a regular, in-home sauna routine, primarily to assist with detoxification. How do we combat this, since doing without screen-based electronics is virtually impossible today unless you are living off-grid in a self-sustaining homestead? Red Light and EyesightĪ few years back, I wrote about how an EMF-free, near-infrared sauna got rid of my eye floaters which I’d had as long as I could remember. These technologies are heavy on blue light, known to disrupt our sleep and contribute to a gradual decline in eyesight over time. However, it doesn’t help that many of us are staring at phone and computer screens much of the day. An antioxidant-rich, ancestral diet can help preserve eyesight and stave off symptoms.
