@drtyna: On this Episode, Dr. Tyna and Jonathan Jarecki dicuss how modern humans live in artificial environments, spending all day indoors under LED lighting that deprives them of the natural light wavelengths our bodies need, damaging mitochondria and eye health. Retinas are constantly bombarded by short-wavelength blue light without the balancing effects of red and infrared light, causing cellular damage. Research shows that blue light exposure increases reactive free radicals that, in excess, harm our cells. #drtyna #drtynashow #podcast #sunlight
