Tis To Season To Be SAD-Savvy

Seasonal Affective Disorder (SAD) is caused by a disrupted circadian rhythm and low serotonin levels. SAD lamps can help alleviate symptoms by mimicking sunlight.

Seasonal Affective Disorder & SAD Lamps

For those of us in the Northern Hemisphere, it’s that time of the year; especially after the clocks recently went back and the nights themselves are getting longer. So, what to do in the season of 3pm darkness?

First: the problem

The problem is twofold:

  1. Our circadian rhythm gets confused
  2. We don’t make enough serotonin

The latter is because serotonin production is largely regulated by sunlight.

People tend to focus on item 2, but item 1 is important too—both as problem, and as means of remedy.

Circadian rhythm is about more than just light

We did a main feature on this a little while back, talking about:

  • What light/dark does for us, and how it’s important, but not completely necessary
  • How our body knows what time it is even in perpetual darkness
  • The many peaks and troughs of many physiological functions over the course of a day/night
  • What that means for us in terms of such things as diet and exercise
  • Practical take-aways from the above

With that in mind, the same methodology can be applied as part of treating Seasonal Affective Disorder.

Serotonin is also about more than just light

Our brain is a) an unbelievably powerful organ, and the greatest of any animal on the planet b) a wobbly wet mass that gets easily confused.

In the case of serotonin, we can have problems:

  • knowing when to synthesize it or not
  • synthesizing it
  • using it
  • knowing when to scrub it or not
  • scrubbing it
  • etc

Selective Serotonin Re-uptake Inhibitors (SSRIs) are a class of antidepressants that, as the name suggests, inhibit the re-uptake (scrubbing) of serotonin. So, they won’t add more serotonin to your brain, but they’ll cause your brain to get more mileage out of the serotonin that’s there, using it for longer.

So, whether or not they help will depend on you and your brain:

How useful are artificial sunlight lamps?

Artificial sunlight lamps (also called SAD lamps), or blue light lamps, are used in an effort to “replace” daylight.

Does it work? According to the science, generally yes, though everyone would like more and better studies:

Interestingly, it does still work in cases of visual impairment and blindness:

How much artificial sunlight is needed?

According to Wirz-Justice and Terman (2022), the best parameters are:

  • 10,000 lux
  • full spectrum (white light)
  • 30–60 minutes exposure
  • in the morning

That one’s a fascinating read, by the way, if you have time.

Can you recommend one?

For your convenience, here’s an example product on Amazon that meets the above specifications, and is also very similar to the one this writer has 😎

  • 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.
