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:
- Our circadian rhythm gets confused
- 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
Read: The Circadian Rhythm: Far More Than Most People Know
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:
- The Efficacy of Light Therapy in the Treatment of Seasonal Affective Disorder: A Meta-Analysis of Randomized Controlled Trials
- Blue-Light Therapy for Seasonal and Non-Seasonal Depression: A Systematic Review and Meta-Analysis of Randomized Controlled Trials
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

What is HRT? HRT and Hormones Explained
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
In this short video, Dr. Sophie Newton explains how menopausal HRT, sometimes called just MHT, is the use of exogenous (didn’t come from your body) to replace/supplement the endogenous hormones (made in your body) that aren’t being made in the quantities that would result in ideal health.
Bioidentical hormones are, as the name suggests, chemically identical to those made in the body; there is no difference, all the way down to the atomic structure.
People are understandably wary of “putting chemicals into the body”, but in fact, everything is a chemical and those chemicals are also found in your body, just not in the numbers that we might always like.
In the case of hormones, these chemical messengers are simply there to tell cells what to do, so having the correct amount of hormones ensures that all the cells that need to get a certain message, get it.
In the case of estrogen specifically, while it’s considered a sex hormone (and it is), it’s responsible for a lot more than just the reproductive system, which is why many people without correct estrogen levels (such as peri- or post-menopause, though incorrect levels can happen earlier in life for other reasons too) can severely feel their absence in a whole stack of ways.
What ways? More than we can list here, but some are discussed in the video:

The Immune System Recovery Plan – by Dr. Susan Blum
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
The subtitle of the book is “A Doctor’s 4-Step Program to Treat Autoimmune Disease”, so we’ll not keep the four steps a secret; they are:
- Using food as medicine
- Understanding the stress connection
- Healing your gut and digestive system
- Optimizing liver function
Each of these sections gives a primer in the relevant science, worksheets for personalizing your own plan to your own situation, condition, and goals, and of course lots of practical advice.
This is important and perhaps the book’s greatest strength, since there are dozens of possible autoimmune conditions, and getting a professional diagnosis is often a long, arduous process. So while this book can’t necessarily speed that up, what it can do is give you a good head-start on managing your symptoms based on things that are most likely to help, and certainly, there will be no harm trying.
While it’s not primarily a recipe book, there are also recipes targeting each part of the whole, as well as an extensive herb and supplement guide, before getting into lots of additional resources.
Bottom line: if you are, or suspect you are, suffering from an autoimmune condition, the information in this book can make your life a lot easier.

Gut Health 2.0
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Gene Expression & Gut Health
This is Dr. Tim Spector. After training in medicine and becoming a consultant rheumatologist, he’s turned his attention to medical research, and is these days a specialist in twin studies, genetics, epigenetics, microbiome, and diet.
What does he want us to know?
For one thing: epigenetics are for more than just getting your grandparents’ trauma.
More usefully: there are things we can do to improve epigenetic factors in our body
DNA is often seen as the script by which our body does whatever it’s going to do, but it’s only part of the story. Thinking of DNA as some kind of “magical immutable law of reality” overlooks (to labor the metaphor) script revisions, notes made in the margins, directorial choices, and ad-lib improvizations, as well as the quality of the audience’s hearing and comprehension.
Hence the premise of one of Dr. Spector’s older books, “Identically Different: Why We Can Change Our Genes”
(*in fact, it was his first, from all the way back in 2013, when he’d only been a doctor for 34 years)
Gene expression will trump genes every time, and gene expression is something that can often be changed without getting in there with CRISPR / a big pair of scissors and some craft glue.
How this happens on the micro level is beyond the scope of today’s article; part of it has to do with enzymes that get involved in the DNA transcription process, and those enzymes in turn are despatched or not depending on hormonal messaging—in the broadest sense of “hormonal”; all the body’s hormonal chemical messengers, not just the ones people think of as hormones.
However, hormonal messaging (of many kinds) is strongly influenced by something we can control relatively easily with a little good (science-based) knowledge: the gut.
The gut, the SAD, and the easy
In broad strokes: we know what is good for the gut. We’ve written about it before at 10almonds:
Making Friends With Your Gut (You Can Thank Us Later)
This is very much in contrast with what in scientific literature is often abbreviated “SAD”, the Standard American Diet, which is very bad for the gut.
However, Dr. Spector (while fully encouraging everyone to enjoy an evidence-based gut-healthy diet) wanted to do one better than just a sweeping one-size-fits-all advice, so he set up a big study with 15,000 identical twins; you can read about it here: TwinsUK
The information that came out of that was about a lot more than just gene expression and gut health, but it did provide the foundation for Dr. Spector’s next project, ZOE.
ZOE crowdsources huge amounts of data including individual metabolic responses to standardized meals in order to predict personalized food responses based on individual biology and unique microbiome profile.
In other words, it takes the guesswork out of a) knowing what your genes mean for your food responses b) tailoring your food choices with your genetic expression in mind, and c) ultimately creating a positive feedback loop to much better health on all levels.
Now, this is not an ad for ZOE, but if you so wish, you can…

- Take the ZOE home gut health test (quiz followed by offers of lab tests)

Why You Should Diversify Your Nuts!
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Time to go nuts for nuts!
Nuts, in popular perception, range from “basically the healthiest food anyone can eat” to “basically high calorie salty snacks”. And, they can be either!
Some notes, then:
- Raw is generally better that not
- Dry roasted is generally better than the kind with added oils
- Added salt is neither necessary nor good
Quick tip: if “roasted salted” are the cheapest or most convenient to buy, you can at least mitigate that by soaking them in warm water for 5 minutes, before rinsing and (if you don’t want wet nuts) drying.
You may be wondering: who does want wet nuts? And the answer is, if for example you’re making a delicious cashew and chickpea balti, the fact you didn’t dry them before throwing them in won’t make a difference.
Now, let’s do a quick run-down; we don’t usually do “listicles” but it seemed a good format here, so we’ve picked a top 5 for nutritional potency:
Almonds
We may have a bias. We accept it. But almonds are also one of the healthiest nuts around, and generally considered by most popular metrics the healthiest.
Not only are they high in protein, healthy fat, fiber, vitamins, and minerals, but they’re even a natural prebiotic that increases the populations of healthy gut bacteria, while simultaneously keeping down the populations of gut pathogens—what more can we ask of a nut?

Pistachios
Not only are these super tasty and fun to eat (and mindful eating is all but guaranteed, as shelling them by hand slows us down and makes us more likely to eat them one at a time rather than by the handful), but also they contain lots of nutrients and are lower in calories than most nuts, so they’re a great option for anyone who’d like to eat more nuts but is doing a calorie-controlled diet and doesn’t want to have half a day’s calories in a tiny dish of nuts.
Walnuts
Popularly associated with brain health (perhaps easy to remember because of their appearance), they really are good for the brain:
Check it out: Beneficial Effects of Walnuts on Cognition and Brain Health
Cashews
A personal favorite of this writer for their versatility in cooking, food prep, or just as a snack, they also do wonders for metabolic health:
Brazil nuts
The most exciting thing about these nuts is that they’re an incredibly potent source of selenium, which is important not just for hair/skin/nails as popularly marketed, but also for thyroid hormone production and DNA synthesis.
But don’t eat too many, because selenium is definitely one of those “you can have too much of a good thing” nutrients, and selenium poisoning can make your hair (however beautiful and shiny it got because of the selenium) fall out if you take too much.
Know the numbers: Brazil nuts and selenium—health benefits and risks
Bottom line on nuts:
- Nuts are a great and healthful part of almost anyone’s diet
- Obviously, if you have a nut allergy, then we’re sorry; this one won’t have helped you so much
- Almonds are one of the most healthful nuts out there
- Brazil nuts are incredibly potent, to the point where moderation is recommended
- A handful of mixed nuts per day is a very respectable option—when it comes to food and health, diversity is almost always good!

Clean – by Dr. James Hamblin
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Our skin is our largest organ, and it’s easy to forget that, and how much it does for us. All things considered, it’s good to take good care of it! But what if we sometimes take too much “care” of it?
Dr. James Hamblin, a medical doctor-turned-writer, has explored this a lot both personally and in research. Through such, he has come to the conclusion there’s definitely a “sweet spot” of personal hygiene:
- Too little, and the Bubonic plague sweeps through Europe, or other plagues sweep through other places when European invaders came.
- Too much, and we strip our skin of one of its greatest qualities: the ability to protect us.
Dr. Hamblin asks (and answers) such questions as:
- What is good hygiene, and what is neurotically doing ourselves multiple levels of harm because advertising companies shamed us into doing so?
- Is it good or bad to use a series of products, each to undo the problem caused by the previous?
- What the difference between a 5-step skincare routine, and a series of gratuitous iatrogenic damage?
- Which products clean us most helpfully, and which clean us most harmfully?
- How often should we bathe/shower, really?
If the book has a weak point, it’s that it’s written mostly with his body in mind. That makes a difference when it comes to hairwashing, for example. He’s a white guy with short hair. If you’re black and/or have long hair, for example, your haircare needs will be quite different. Similarly, many women engage in shaving/depilation in places that most men don’t, and the consequences of that choice (and implications for any extra washing needs/harms) aren’t covered.
Bottom line: notwithstanding the aforementioned blind-spots, this book will help readers reduce the amount of harm we are doing to our bodies with our washing routines, without sacrificing actual hygiene.

Why scrapping the term ‘long COVID’ would be harmful for people with the condition
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
The assertion from Queensland’s chief health officer John Gerrard that it’s time to stop using the term “long COVID” has made waves in Australian and international media over recent days.
Gerrard’s comments were related to new research from his team finding long-term symptoms of COVID are similar to the ongoing symptoms following other viral infections.
But there are limitations in this research, and problems with Gerrard’s argument we should drop the term “long COVID”. Here’s why.
A bit about the research
The study involved texting a survey to 5,112 Queensland adults who had experienced respiratory symptoms and had sought a PCR test in 2022. Respondents were contacted 12 months after the PCR test. Some had tested positive to COVID, while others had tested positive to influenza or had not tested positive to either disease.
Survey respondents were asked if they had experienced ongoing symptoms or any functional impairment over the previous year.
The study found people with respiratory symptoms can suffer long-term symptoms and impairment, regardless of whether they had COVID, influenza or another respiratory disease. These symptoms are often referred to as “post-viral”, as they linger after a viral infection.
Gerrard’s research will be presented in April at the European Congress of Clinical Microbiology and Infectious Diseases. It hasn’t been published in a peer-reviewed journal.
After the research was publicised last Friday, some experts highlighted flaws in the study design. For example, Steven Faux, a long COVID clinician interviewed on ABC’s television news, said the study excluded people who were hospitalised with COVID (therefore leaving out people who had the most severe symptoms). He also noted differing levels of vaccination against COVID and influenza may have influenced the findings.
In addition, Faux pointed out the survey would have excluded many older people who may not use smartphones.
The authors of the research have acknowledged some of these and other limitations in their study.
Ditching the term ‘long COVID’
Based on the research findings, Gerrard said in a press release:
We believe it is time to stop using terms like ‘long COVID’. They wrongly imply there is something unique and exceptional about longer term symptoms associated with this virus. This terminology can cause unnecessary fear, and in some cases, hypervigilance to longer symptoms that can impede recovery.
But Gerrard and his team’s findings cannot substantiate these assertions. Their survey only documented symptoms and impairment after respiratory infections. It didn’t ask people how fearful they were, or whether a term such as long COVID made them especially vigilant, for example.
In discussing Gerrard’s conclusions about the terminology, Faux noted that even if only 3% of people develop long COVID (the survey found 3% of people had functional limitations after a year), this would equate to some 150,000 Queenslanders with the condition. He said:
To suggest that by not calling it long COVID you would be […] somehow helping those people not to focus on their symptoms is a curious conclusion from that study.
Another clinician and researcher, Philip Britton, criticised Gerrard’s conclusion about the language as “overstated and potentially unhelpful”. He noted the term “long COVID” is recognised by the World Health Organization as a valid description of the condition.
A cruel irony
An ever-growing body of research continues to show how COVID can cause harm to the body across organ systems and cells.
We know from the experiences shared by people with long COVID that the condition can be highly disabling, preventing them from engaging in study or paid work. It can also harm relationships with their friends, family members, and even their partners.
Despite all this, people with long COVID have often felt gaslit and unheard. When seeking treatment from health-care professionals, many people with long COVID report they have been dismissed or turned away.
Last Friday – the day Gerrard’s comments were made public – was actually International Long COVID Awareness Day, organised by activists to draw attention to the condition.
The response from people with long COVID was immediate. They shared their anger on social media about Gerrard’s comments, especially their timing, on a day designed to generate greater recognition for their illness.
Since the start of the COVID pandemic, patient communities have fought for recognition of the long-term symptoms many people faced.
The term “long COVID” was in fact coined by people suffering persistent symptoms after a COVID infection, who were seeking words to describe what they were going through.
The role people with long COVID have played in defining their condition and bringing medical and public attention to it demonstrates the possibilities of patient-led expertise. For decades, people with invisible or “silent” conditions such as ME/CFS (myalgic encephalomyelitis/chronic fatigue syndrome) have had to fight ignorance from health-care professionals and stigma from others in their lives. They have often been told their disabling symptoms are psychosomatic.
Gerrard’s comments, and the media’s amplification of them, repudiates the term “long COVID” that community members have chosen to give their condition an identity and support each other. This is likely to cause distress and exacerbate feelings of abandonment.
Terminology matters
The words we use to describe illnesses and conditions are incredibly powerful. Naming a new condition is a step towards better recognition of people’s suffering, and hopefully, better diagnosis, health care, treatment and acceptance by others.
The term “long COVID” provides an easily understandable label to convey patients’ experiences to others. It is well known to the public. It has been routinely used in news media reporting and and in many reputable medical journal articles.
Most importantly, scrapping the label would further marginalise a large group of people with a chronic illness who have often been left to struggle behind closed doors.
