International Commission on Non-Ionizing Radiation Protection Issues Statement on Harms of Short Wavelength Light

Read Article

A joint statement by the entire ICNIRP (International Commission on Non-Ionizing Radiation Protection) finds that “Exposure to SWL (short wavelength light) has been shown to interfere with some IIL (intrinsically-photosensitive retinal ganglion cell (ipRGC)-influenced light) responses in a wavelength-dependent manner in some studies. It has generally been assumed that exposure to SWL at night will cause alertness and affect sleep quality. However, due to limited data and conflicting results regarding effects on alertness, sleepiness, and sleep it is not possible to reach a conclusion about effects on these outcomes.”
