RR172 Blue Light Up All Night
WARNING Expletive PG-13 words damn it and God
Blue light is good for you if you want to stay awake. If you are hoping to fall asleep anytime soon avoid it. This means any source of blue light including your phone, TV, laptop, desktop and for folks north of the Arctic south of the Antarctic, American Southwest and northeastern Africa the sun.
“implying a causal relationship between two things that are actually unrelated: the light emitted by digital screens and the strain we feel from looking at any one thing for too long.”
“according to Rahul Khurana, an ophthalmologist and clinical spokesperson for the American Academy of Ophthalmology, digital eyestrain and the negative effects of blue light on your eyes are two separate concerns”
Although I found most websites touting that blue light glasses prevent eye strain. Can you say snake oil?
Some give tips on how to combat blue light exposure but you do not need their glasses in order to accomplish this issue.
If your eyes are bothering you BLINK. Blink completely and often.
According to Harvard Health “...research shows that it may contribute to the causation of cancer, diabetes, heart disease, and obesity.” Certainly this is spurious or at the very least correlated not causal because if our sleep is disrupted in the extreme, often enough it can literally kill us.
Okay there is some research that connects the instance of diabetes with disruption of the circadian rhythm but the sample size is way too small to have any substantial validity.
“A Harvard study shed a little bit of light on the possible connection to diabetes and possibly obesity. The researchers put 10 people on a schedule that gradually shifted the timing of their circadian rhythms. Their blood sugar levels increased, throwing them into a prediabetic state, and levels of leptin, a hormone that leaves people feeling full after a meal, went down.”
“too much exposure to blue light can damage light-sensitive cells in the retina. This causes changes that resemble those of macular degeneration, which can lead to permanent vision loss.”
Blue light does a body good: “It's well documented that some blue light exposure is essential for good health. Research has shown that high-energy visible light boosts alertness, helps memory and cognitive function and elevates mood.”
Remember blue light messes with sleep and the ability to produce melatonin. No, that does not suggest taking melatonin. If you have enough serotonin you can make all the melatonin you need.
Sometimes the lack of sleep can be easily rectified by staying away from blue light sources two the three hours before bedtime.
Sometimes depression and feeling down can be mitigated by being outside or having blue light therapy.
