If you're willing, it would also be interesting to hear how the Bedtime Bulb from a past Show HN fares: https://news.ycombinator.com/item?id=18011075

Do you know how to order one without Amazon? I'm... rather opposed to them. In every possible way one could consider. I would love to poke with one, but if the only way to buy one is through Amazon, I'm quite unlikely to actually obtain one. I genuinely don't care if I have to pay a bit more, I hate what Amazon has done to retail.

For the "just take melatonin" crowd: some of us can't. Its contraindicated for high blood pressure. and, for some people causes florid dreams (not always welcome) and "restless legs"

Is "florid dreams" a thing (Google didn't come up with anything meaningful)? Did you mean lucid dreams (though for the life of me, I can't understand why that wouldn't be welcomed).

No, it's not a thing, its a term my partner used. Lucid dreams you have (within limits) control over the narrative, florid dreams she described as hyper-real, disturbing and unwelcome.

"vivid dream melatonin" had heaps of hits. "melatonin nightmares" might be another way of putting it.

I suspect that (some types of) plastics are going to be a big contributer to some of these problems. They contain a number of endocrine disrupting chemicals, and we're typing on them, mousing with them, steering our cars with them, walking on them (most carpet is plastic these days), wearing them, eating off them, drinking from them, washing outselves with them ... But yeah, the time-lag is a real problem, and couple…

> They contain a number of endocrine disrupting chemicals … Tangential, but I worry about the oleophobic materials used on touchscreen glass panels.

Also keyboards, clothing and furniture.

There are also probably very personal and biological variables involved too that the post doesn't mention. I stare into monitors and phones all day long. Every light in the house is full-blown LED. I can't help but fall asleep at 20:00 in an led lit room watching led TVs, while my led phone drops onto the floor after I've fallen asleep. I've been in an extreme LED environment for over a decade and never have problems…

I've battled the opposite in the form of clinical, anxiety-driven insomnia my whole life. I've found it utterly debilitating at times and have quite literally struggled since birth, long before electronics and LEDs were common. I can confidently say you're so right about the number (and type) of variables. Sleep hygiene as we say in the biz is a very complex and personal issue. I've tried everything under the sun fro…

I relate very much to this. In particular the well intended but ignorant suggestions.. I think it's often hard for most people to truly appreciate a problem they don't have.

There is always a time lag between the introduction of a cool new technology, and the discovery of its negative effects on human health. DDT was invented in the 1940's, and it wasn't until twenty years later that people discovered its negative effects through bioaccumulation. Teflon was invented in the 1930's, and it again took decades to discover its negative effects on human health, apparently under high heat. Ciga…

Regarding the quoted e-book study: > Third, in the present study, the LE-eBook was set to maximum brightness throughout the 4-h reading session, whereas, by comparison, the print-book condition consisted of reflected exposure to very dim light. Yeah, max brightness is probably going to make an impact. I bet if you were in a room with a bright light reading a book, with an equivalent amount of lumens going into your e…

But then you can't sell blue blocking products.

General rule I keep is the more restrained on new tech you can be the better. Basically, I avoid most synthetic, gmo, store bought stuff where I can. That said, I have AC, heat, and will use meds when I need them (even real advanced ones). There’s always risks but my cast iron works great to cook with. No synthetic hormones for me, and limit phone use is allgood.

Do you also avoid animal products? Lotta hormones in those.

What's the scientific opinion on blue blockers for prescription eyeglasses? There are some claims that suggest the health benefits are over stated. But my optometrist continues to recommend them given my profession and exposure to blue light.

Anecdotally, it appears it has helped but not sure if it's related to other factors.
