Harrison a permanent activated immune system (doctors told me that) - the body is fighting against something
I'm coming back to this older post because I've recently read some research that shows that light flicker causes neuroinflammation. Visible 40 Hz strobe light flicker causes neuroinflammation in mice. Researchers thought this was potentially good because, when done for a relatively short period of time, it could cause immune cells in the brain to clear away abnormal proteins involved in Alzheimer's disease. This review article has a well-written discussion of that research and other research on noninvasive strategies for changing brain waves.
Another recent paper shows that different kinds of visible light flicker (40 Hz, 20 Hz, irregular flicker averaging at 40 Hz) very rapidly caused immune system system signaling molecules to be activated in the mouse brain's visual cortex, and the collection of immune molecules that was activated varied based on the type of flicker. A conclusion of the paper was that light flicker could potentially be used in therapies where it was desirable to cause an immune response (inflammation) in the brain.
I haven't seen any research of this kind studying "invisible" flicker of the ≥100 Hz or ≥120 Hz kind that we experience from LED lights, so there's no way to know if it, too, could trigger inflammation in the brain. However, I wonder if for some of us, this could possibly be the case. Additionally, it's hard to say what kind of flicker frequency or pattern we're getting from the numerous ways that LED screens can flicker. The amount of time that people are being exposed to LED flicker is also, of course, much longer than in the mouse studies.
Too much neuroinflammation is definitely bad. For example, concussion causes neuroinflammation, and lingering neuroinflammation is thought to be a cause of long-term negative consequences of concussion in the brain.
Having neuroinflammation could possibly explain some of the memory and sleep problems that some of us have. For me at least, my memory and lingering sleep issues (I can't stay asleep for more than a few hours for many days/weeks following LED exposure) seem similar to what some people experience for long periods of time after a concussion.
I really hope neuroinflammation isn't part of what we're dealing with, but if it is, it can be tricky to detect with a blood test. @Harrison do you happen to know what kind of immune system marker your doctors detected?
