Melatonin: A Safe, Natural Sleep Aid?

Melatonin: A safe sleep aid? This hormone helps regulate our sleep-wake cycle and has additional benefits such as improving sleep quality and potentially treating Seasonal Affective Disorder. Consult your doctor before use.
Is melatonin a safe and natural sleep supplement?

Melatonin: A safe sleep supplement?

Melatonin is a hormone normally made in our pineal gland. It helps regulate our circadian rhythm, by making us sleepy.

It has other roles too—it has a part to play in regulating immune function, something that also waxes and wanes as a typical day goes by.

Additionally, since melatonin and cortisol are antagonistic to each other, a sudden increase in either will decrease the other. Our brain takes advantage of this, by giving us a cortisol spike in the morning to help us wake up.

As a supplement, it’s generally enjoyed with the intention of inducing healthy, natural, restorative sleep.

Does it really induce healthy, natural, restorative, sleep?

Yes! Well, “natural” is a little subject and relative, if you’re taking it as a supplement, but it’s something your body produces naturally anyway.

Contrast with, for example, benzodiazepines (that whole family of medications with names ending in -azopan or -alozam), or other tranquilizing drugs that do not so much induce healthy sleep, but rather reduce your brain function and hopefully knock you out, and/but often have unwanted side effects, and a tendency to create dependency.

Melatonin, unlike most of those drugs, does not create dependency, and furthermore, we don’t develop tolerance to it. In other words, the same dose will continue working (we won’t need more and more).

In terms of benefits, melatonin not only reduces the time to fall asleep and increases total sleep time, but also (quite a bonus) improves sleep quality, too:

Because it is a natural hormone rather than a drug with many side effects and interactions, it’s also beneficial for those who need good sleep and/but don’t want tranquilizing:

Any other benefits?

Yes! It can also help guard against Seasonal Affective Disorder, also called seasonal depression. Because SAD is not just about “not enough light = not enough serotonin”, but also partly about circadian rhythm and (the body is not so sure what time of day it is when there are long hours of darkness, or even, in the other hemisphere / other time of year, long hours of daylight), melatonin can help, by giving your brain something to “anchor” onto, provided you take it at the same time each day. See:

As a small bonus, melatonin also promotes HGH production (important for maintaining bone and muscle mass, especially in later life):

Melatonin stimulates growth hormone secretion through pathways other than the growth hormone-releasing hormone

Anything we should worry about?

Assuming taking a recommended dose only (0.5mg–10mg per day), toxicity is highly unlikely, especially given that it has a half-life of only 40–60 minutes, so it’ll be eliminated quite quickly.

However! It does indeed induce sleepiness, so for example, don’t take melatonin and then try to drive or operate heavy machinery—or, ideally, do anything other than go to bed.

It can interfere with some medications. We mentioned that melatonin helps regulate immune function, so for example that’s something to bear in mind if you’re on immunosuppressants or otherwise have an autoimmune disorder. It can also interfere with blood pressure medications and blood thinners, and may make epilepsy meds less effective.

As ever, if in doubt, please speak with your doctor and/or pharmacist.

Where to get it?

As ever, we don’t sell it (or anything else), but for your convenience, here is an example product on Amazon.

  • 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:

    1. Knowing stuff
    2. Doing stuff

    So it becomes our responsibility (and our lifeline) to educate ourselves, and take action accordingly.
