Blue Light At Night? Save More Than Just Your Sleep!
Beating The Insomnia Blues: Tips for better sleep include avoiding caffeine and alcohol before bed, fresh bedding, a warm bed and cool room, and keeping the room dark.
Beating The Insomnia Blues
You previously asked us about recipes for insomnia (or rather, recipes/foods to help with easing insomnia). We delivered!
But we also semi-promised we’d cover a bit more of the general management of insomnia, because while diet’s important, it’s not everything.
Sleep Hygiene
Alright, you probably know this first bit, but we’d be remiss if we didn’t cover it before moving on:
- No caffeine or alcohol before bed
- Ideally: none earlier either, but if you enjoy one or the other or both, we realize an article about sleep hygiene isn’t going to be what changes your mind
- Fresh bedding
- At the very least, fresh pillowcase(s). While washing and drying an entire bedding set constantly may be arduous and wasteful of resources, it never hurts to throw your latest pillowcase(s) in with each load of laundry you happen to do.
- Warm bed, cool room = maximum coziness
- Dark room. Speaking of which…
About That Darkness…
When we say the room should be dark, we really mean it:
- Not dark like “evening mood lighting”, but actually dark.
- Not dark like “in the pale moonlight”, but actually dark.
- Not dark like “apart from the light peeking under the doorway”, but actually dark.
- Not dark like “apart from a few LEDs on electronic devices that are on standby or are charging”, but actually dark.
There are many studies about the impact of blue light on sleep, but here’s one as an example.
If blue light with wavelength between 415 nm and 455 nm (in the visible spectrum) hits the retina, melatonin (the sleep hormone) will be suppressed.
The extent of the suppression is proportional to the amount of blue light. This means that there is a difference between starting at an “artificial daylight” lamp, and having the blue LED of your phone charger showing… but the effect is cumulative.
And it gets worse:
❝This high energy blue light passes through the cornea and lens to the retina causing diseases such as dry eye, cataract, age-related macular degeneration, even stimulating the brain, inhibiting melatonin secretion, and enhancing adrenocortical hormone production, which will destroy the hormonal balance and directly affect sleep quality.❞
Read it in full: Research progress about the effect and prevention of blue light on eyes

So, what this means, if we value our health, is:
- Switch off, or if that’s impractical, cover the lights of electronic devices. This might be as simple as placing your phone face-down rather than face-up, for instance.
- Invest in blackout blinds/curtains (per your preference). Serious ones, like these ← see how they don’t have to be black to be blackout! You don’t have to sacrifice style for function 😎
- If you can’t reasonably do the above, consider a sleep mask. Again, a good one. Not the kind you were given on a flight, or got free with some fluffy handcuffs. We mean a full-blackout sleep mask that’s designed to be comfortable enough to sleep in, like this one.
- If you need to get up to pee or whatever, do like a pirate and keep one eye covered/closed. That way, it’ll remain unaffected by the light. Pirates did it to retain their night vision when switching between being on-deck or below, but you can do it to halve the loss of melatonin.
Lights-Out For Your Brain Too
You can have all the darkness in the world and still not sleep if your mind is racing thinking about:
- your recent day
- your next day
- that conversation you wish had gone differently
- what you really should have done when you were 18
- how you would go about fixing your country’s socio-political and economic woes if you were in charge
- Etc.
We wrote about how to hit pause on all that, in a previous edition of 10almonds.

Stop Cancer 20 Years Ago
Dr. Jenn Simmons shares vital tips on preventing cancer and inflammation, advocating for lifestyle changes and proactive health management at any age.
Get Abreast And Keep Abreast
This is Dr. Jenn Simmons. Her specialization is integrative oncology, as she—then a breast cancer surgeon—got breast cancer, decided the system wasn’t nearly as good from the patients’ side of things as from the doctors’ side, and took to educate herself, and now others, on how things can be better.
What does she want us to know?
Start now
If you have breast cancer, the best time to start adjusting your lifestyle might be 20 years ago, but the second-best time is now. We realize our readers with breast cancer (or a history thereof) probably have indeed started already—all strength to you.
What this means for those of us without breast cancer (or a history therof) is: start now
Even if you don’t have a genetic risk factor, even if there’s no history of it in your family, there’s just no reason not to start now.
Start what, you ask? Taking away its roots. And how?
Inflammation as the root of cancer
To oversimplify: cancer occurs because an accidentally immortal cell replicates and replicates and replicates and takes any nearby resources to keep on going. While science doesn’t know all the details of how this happens, it is a factor of genetic mutation (itself a normal process, without which evolution would be impossible), something which in turn is accelerated by damage to the DNA. The damage to the DNA? That occurs (often as not) as a result of cellular oxidation. Cellular oxidation is far from the only genotoxic thing out there, and a lot of non-food “this thing causes cancer” warnings are usually about other kinds of genotoxicity. But cellular oxidation is a big one, and it’s one that we can fight vigorously with our lifestyle.
Because cellular oxidation and inflammation go hand-in-hand, reducing one tends to reduce the other. That’s why so often you’ll see in our Research Review Monday features, a line that goes something like:
“and now for those things that usually come together: antioxidant, anti-inflammatory, anticancer, and anti-aging”
So, fight inflammation now, and have a reduced risk of a lot of other woes later.
See: How to Prevent (or Reduce) Inflammation
Don’t settle for “normal”
People are told, correctly but not always helpfully, such things as:
- It’s normal to have less energy at your age
- It’s normal to have a weaker immune system at your age
- It’s normal to be at a higher risk of diabetes, heart disease, etc
…and many more. And these things are true! But that doesn’t mean we have to settle for them.
We can be all the way over on the healthy end of the distribution curve. We can do that!
(so can everyone else, given sufficient opportunity and resources, because health is not a zero-sum game)
If we’re going to get a cancer diagnosis, then our 60s are the decade where we’re most likely to get it. Earlier than that and the risk is extant but lower; later than that and technically the risk increases, but we probably got it already in our 60s.
So, if we be younger than 60, then now’s a good time to prepare to hit the ground running when we get there. And if we missed that chance, then again, the second-best time is now:
See: Focusing On Health In Our Sixties
Fast to live
Of course, anything can happen to anyone at any age (alas), but this is about the benefits of living a fasting lifestyle—that is to say, not just fasting for a 4-week health kick or something, but making it one’s “new normal” and just continuing it for life.
This doesn’t mean “never eat”, of course, but it does mean “practice intermittent fasting, if you can”—something that Dr. Simmons strongly advocates.
See: Intermittent Fasting: We Sort The Science From The Hype
While this calls back to the previous “fight inflammation”, it deserves its own mention here as a very specific way of fighting it.
It’s never too late
All of the advices that go before a cancer diagnosis, continue to stand afterwards too. There is no point of “well, I already have cancer, so what’s the harm in…?”
The harm in it after a diagnosis will be the same as the harm before. When it comes to lifestyle, preventing a cancer and preventing it from spreading are very much the same thing, which is also the same as shrinking it. Basically, if it’s anticancer, it’s anticancer, no matter whether it’s before, during, or after.
Dr. Simmons has seen too many patients get a diagnosis, and place their lives squarely in the hands of doctors, when doctors can only do so much.
Instead, Dr. Simmons recommends taking charge of your health as best you are able, today and onwards, no matter what. And that means two things:
- Knowing stuff
- Doing stuff
So it becomes our responsibility (and our lifeline) to educate ourselves, and take action accordingly.
