I've been reading a few papers on
Suprachiasmatic Nucleus (SCN), and see that the sleep/wake transition is influenced and entrained by visible light, particularly in the blue spectrum that is registered by special cones in the eye and is transmitted to the SCN.
I've seen a fleeting hypothesis/mention in two of these articles, that electromagnetic radiation may also play a part in the sleep/wake transition and melatonin release, on top of the blue light. It was some time after I read those articles that it dawned on me to ask this question, and I'm unable to find the exact lines where the mention was made.
Has there been any modern studies on the connection between electro-magnetic radiation (non-visible spectrum) and the human's circadian rhythm entrainment?
Can humans be affected or feel the influence of electro magnetic radiation at all?
If there is a connection, what is the name of a process/organ/gland by which humans can be affected with electromagnetic radiation?
Thank you for your clarification!
