(B.N. Frank) There IS research that has already determined that exposure from cell phones and other sources of wireless (WiFi) radiation is harmful. It has been linked to cancer, mental health issues, and much more.

In fact, there are currently cancer survivors awaiting the outcome of a smartphone class action lawsuit that was filed last year.
There is also research that has already determined that Blue Light exposure from screens and other sources affects human health in a variety of undesirable ways.
Thanks to Environmental Health Trust for posting the results of a 2020 study on Blue Light.
From Environmental Health Trust:
Smartphone Blue Light is Linked to Colon Cancer and Depression
Smartphones emit several types of electromagnetic fields that can harm our health. In addition to harmful radio-frequency radiation, they also emit blue light. While humans have always been exposed to natural blue light frequencies in nature, our use of smartphones and screens has resulted in unprecedented exponentially increased exposures at all hours of the day and night.
A 2020 study on colorectal cancre and blue light at night with over 2000 subjects found outdoor blue light at night is linked to colon cancer.

Artificial blue light can damage the eyes, contribute to aging of the skin and harm our sleep. It is linked to depression and mental health problems.
“To understand why shining the blue light at the mice led to depression, the researchers studied their brains—most specifically, the neural pathways that lead from the eyes to the brain. They found a specific kind of light receptor in the mouse retina that led to brain areas associated with mood: the nucleus accumbens and the dorsal perihabenular nucleus. When the researchers disconnected them, the mice did not become depressive due to exposure to blue light at night. The researchers also found that the pathways became much more active when processing blue light at night versus daytime—which, they suggest, explains why blue light during the day does not lead to depression.” -Medical Express “Exposing Mice to Blue light Leads to Depressive Symptoms”

- Blue filtered light induces depression-like symptoms and temporary spatial learning deficits in rats, which might be closely related to the impairment of light-evoked output signals in the retina.

- We investigated the association between exposure to ALAN according to light spectrum and colorectal cancer among subjects who had never worked at night in a general population case–control study in Spain.
- Exposure to blue light spectrum was positively associated with colorectal cancer (OR = 1.6; 95% CI: 1.2–2.2; highest vs. lowest tertile).
- Outdoor blue light spectrum exposure that is increasingly prevalent in recent years may be associated with colorectal cancer risk.

- “This study investigated the immediate effects of smartphone blue light LED on humans at night. We investigated changes in serum melatonin levels, cortisol levels, body temperature, and psychiatric measures with a randomized, double-blind, cross-over, placebo-controlled design…”
- “use of blue light smartphones was associated with significantly decreased sleepiness (Cohen’s d = 0.49, Z = 43.50, p = 0.04) and confusion-bewilderment (Cohen’s d = 0.53, Z = 39.00, p = 0.02), and increased commission error “

- Exposing human skin to the blue light contained in sunlight depressed flavin autofluorescence, demonstrating that the visible component of sunlight has a physiologically significant effect on human skin. The ROS produced by blue light is probably superoxide, but not singlet oxygen. These results suggest that blue light contributes to skin aging similar to UVA.

- We provide further evidence that blocking short-wavelength light in the evening hours may be beneficial for patients suffering from insomnia.
Stillness in the Storm Editor: Why did we post this?
The news is important to all people because it is where we come to know new things about the world, which leads to the development of more life goals that lead to life wisdom. The news also serves as a social connection tool, as we tend to relate to those who know about and believe the things we do. With the power of an open truth-seeking mind in hand, the individual can grow wise and the collective can prosper.
