Research shows both blue light and UVA light boost the activity of T lymphocytes. As little as five to 10 minutes of sun exposure was needed to boost immune cell activity.
The healthiest blue light is from the sun, as it is balanced by near-infrared radiation, which activates cytochrome C oxidase in your mitochondria and helps optimise ATP production.
Mounting research confirms that sun avoidance may be at the heart of a large number of health problems. Not only does your body produce vitamin D in response to sun exposure on bare skin, but sunlight also produces several other health benefits that are unrelated to vitamin D production.
In fact, humans appear to have a lot in common with plants in this regard – we both need direct sun exposure to optimally thrive, and while artificial lighting sources offering specific light spectrums may be helpful for various problems, ideally we need the full spectrum of light that natural sunlight offers. More recently, researchers at Georgetown University Medical Centre (“GUMC”) published a laboratory study using cells in Petri dishes, showing that exposure to blue and ultraviolet (“UV”) light increases T cell activity – white blood cells involved in immune function and fighting infections....<<<Read More>>>...
