To put it simply, EMF and blue light interfere with something in our body called cryptochrome protein; and the fix is grounding, avoiding blue light, and turning off EMF sources such as WiFi at night. I find this fascinating and my recent experience with grounded bedsheets has both my wife and I amazed at how much better we are sleeping.
The Earth’s Role in Circadian Regulation: Grounding to Set Daily Cortisol Pattern
Laura Koniver MD

*"Recent studies suggest that the SCN may receive and integrate geomagnetic signals via magneto receptive structures in the retina or through cryptochrome proteins, which are sensitive not only to **light **but also to weak **electromagnetic fields *. In fact, cryptochromes—essential to circadian timing—have been shown in animal models to be responsive to static and oscillating magnetic fields at frequencies overlapping the Earth’s natural resonances . This supports the hypothesis that our circadian pacemakers are not exclusively photic-dependent but may also be co-regulated by Earth’s electromagnetic architecture. Direct contact with the Earth, a practice known as grounding or earthing, may influence cortisol rhythms in a significant and clinically relevant way. This article explores historical and contemporary evidence that grounding supports the biological clock via entrainment of cortisol rhythms and restoration of autonomic balance."
How do homing pigeons know their direction? They make better use of cryptochrome proteins than we do (located in the retina). They literally can see the magnetic fields of the earth.
Cryptochrome proteins are in our bodies (retinas) as well and they are especially helpful for us with respect to sleep and circadian rhythm, which is so critical to our health. I was very curious and dug to learn how these interact with magnetic fields. It’s more technical than I understand but it’s a quantum level effect with “radical pairs” (see the WIKI on Cryptochrome Protein).
Why I was curious about the magnetic field detection is that EMF literally means Electro-Magnetic Fields. I reasoned that if we have cryptochrome proteins that are so sensitive that a bird can see the weak magnetic fields of the Earth, then what does EMF do to our cryptochrome proteins? No one has done this research yet, but we can ask a different question:

That sounds like a delightful interaction you had and a wonderful day. I would have struggled with that one based on my limited Spanish… I can hear myself saying “dentro del cuerpo”, “es como relampago”, “ayuda con la inflamacion” and “muy saludable y cientifico” trying to piece the ideas together and getting funny looks from a Spaniard.
Me too. My wife has forced me (or she would say suggested) to leave my phone out of the bedroom, and last night I turned off (airplane moded) my kindle. Now I’ve got to work out how to sleep the wifi too.
