TOP. MEN.

Am I the only one weirded out that a Stanford prof keeps pushing pseudoscience and shady supplements? Highly unethical.

Maybe instead of posting a meaningless screenshot of a tweet you could link to this "strong data"? But that would require effort on your part I suppose.

IDK but those LED lights that's on every new car today is blinding and hurts my eyes

On the internet a short catchy tweet gets more attention than a text-dense scientific journal.

this is literally you whenever you flip a light switch. you just don;t know it yet. they're hiding the truth from us.

What about your eyeballs though nigga?

IIRC the problem was about the imbalance in light spectrums.
But what's the problem, do you really have to stare at full LED white all the waking hours? Can't you open windows or enable night mode?!?!?!?

>Are LEDs Bad For You?
Yes
>As bad as asbestos, even?
No, asbestos is worse.
>Damaging to the DNA level?
I doubt it. If you mean damaging in the sense of frying cells like a microwave, I would say no. It may be potentially possible in the realm of influencing gene expression, but I am not an expert on that topic. If there were convincing evidence, I'd peruse it. But I wouldn't panic over it either.

All said, LEDs are unpleasant, poor sources of light that do not reproduce color accurately, and this can affect mood negatively, which can affect other bodily processes in difficult to determine ways, some of which we may not fully understand yet. Stress and mood should never be discounted as major sources of health concerns. They can cause dramatic physiological responses.

People in the X thread claim than the temperature of you LED doesn't change much. They give no evidence, though. Maybe they are right. What's sure, is that they do a poor job at being convincing.
Light therapy is a real thing, so perhaps there is an antagonist to it too.

The "temperature" of a light (its overall color tone, e.g. "pure white", "cool blue", "warm orange") is separate from its ability to accurately reproduce the spectrum. It doesn't really matter in the end, what matters is whether the light can accurately reproduce individual colors within the spectrum, and LEDs are inferior (fluorescents are worse, but LEDs are still lacking).

You can have an LED white light and an incandescent white light of the same brightness and shine both at a white wall, and both may look exactly the same. The problem starts with reproducing the colors of all the objects in our environment. The "white" that is sunlight contains the entirety of the visible spectrum (because that's what we evolved to perceive). But artificial light contains fewer wavelengths mixed together. This can still look "white" (or bluish, or orangeish, depending on what "temperature" you buy), but objects will look visibly different under artificial lighting because the correct wavelengths of light for them to appear natural simply aren't being emitted by the source.

You may have seen images like this and thought they were just marketing gobbledygook cooked up to sell products, but it's not. It's a real visible effect. And constantly living under these lights make everything look wrong, dull, and sickly, and it influences mood.

>simply aren't being emitted by the source
*or are being emitted in incorrect ratios, with some wavelengths overemphasized to compensate for less intense ones, resulting in the visible "wrongness" of object colors.

Incandescent lightbulbs do not reproduce the exact spectrum of sunlight, but they produce a much more linear gradient than LEDs and fluorescents, resulting in a form of light that, while visibly not identical to sunlight, is not as displeasing as artificials.
