Seasonal Affective Disorder (Beyond Sunlight!)

For those of us in the Northern Hemisphere, the time of increasing darkness is upon us again. Depending on our latitude, the sun barely rises before it skitters off again. And depending on other factors of our geography, we might not get much sun during that time (writer’s example: the ancient bog from which I write has been surrounded by fog for two weeks now).

So, what to do about it?

Firstly, we can make the most of whatever sun we do get (especially in the morning, if possible), and we can of course make some use of artificial sunlight. To save doubling up, we’ll link to what we previously wrote about optimizing both of those things:

‘Tis To Season To Be SAD-Savvy

More ways to get serotonin

Sunlight, of course, triggers our bodies to make serotonin, and hence we often make less of it during winter. But, there are other ways to get serotonin too, and one of the best ways is spending time in nature. Yes, even if the weather is gloomy, provided there are still visible green things and you are seeing them, it will promote serotonin production.

Of course, it may not be the season for picnics, but a morning walk through a local park or other green space is ideal.

On which note, gardening remains a good activity. Not a lot of people do so much gardening after a certain point in the year, but in one way, it’s more important than ever to get some soil under your fingernails:

There are bacteria in soil (specifically: Mycobacterium vaccae) that work similarly to antidepressants.

When something is described as having an effect similar to antidepressants, it’s usually hyperbole. In this case, it’s medicine, and literally works directly on the serotonergic system (as do many, but not all, antidepressants).

While many antidepressants are selective serotonin uptake inhibitors (i.e., they slow the rate at which your brain loses serotonin), Mycobacterium vaccae increases the rate at which you produce serotonin. So, you feel happier, more relaxed, while also feeling more energized.

See: Identification of an immune-responsive mesolimbocortical serotonergic system: Potential role in regulation of emotional behavior

^this one’s a mouse study, but we’re including it because it covers exactly how it works in the brain, which is something that the ethics board wouldn’t let them do on humans, due to the need for slicing the brains up for examination.

As to how to benefit: touching soil will get you “infected” by the bacteria, yes, even if you wash your hands later. Growing food in the soil and eating the good (including if you wash and cook it) is even better.

Boost the other “happiness chemicals”

Serotonin is just one “happiness hormone”, other feel-good neurotransmitters that are just as important include dopamine and oxytocin.

Dopamine is most associated with being the “reward chemical”, so it pays to do things that you find rewarding. If you’re stuck for ideas, engaging in small acts of kindness is a sure-fire way to get dopamine flowing and lift your own mood as well as theirs.

Oxytocin, meanwhile is the “cuddle chemical”, and can be triggered even if you have nobody to cuddle*. If you do, by the way, make it at least 20–30 seconds, as that’s generally how long it takes to get oxytocin flowing.

*Vividly imagining it has much the same effect, since the brain can’t tell the difference. Alternatively, looking at pictures/videos (your choice) of small cute animals tends to work for most people also.

  • L-Theanine: What’s The Tea?

    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.

    L-Theanine: What’s The Tea?

    We’ve touched previously on l-theanine, when this newsletter was new, and we had only a few hundred subscribers and the carefully organized format wasn’t yet what it is today.

    So now it’s time to give this potent dietary compound / nutritional supplement the “Monday Research Review” treatment…

    What is it?

    L-theanine is an amino acid found in tea. The human body can’t produce it, and/but it’s not essential for humans. It does have a lot of benefits, though. See for example:

    L-Theanine as a Functional Food Additive: Its Role in Disease Prevention and Health Promotion

    How does it work?

    L-theanine works by moderating and modulating the brain’s neurotransmitters.

    This sounds fancy, but basically it means: it doesn’t actually add anything in the manner of a drug, but it changes how we use what we have naturally.

    What does it do? Read on…

    It increases mental focus

    It has been believed that l-theanine requires the presence of caffeine to achieve this (i.e., it’s a combination-only effect). For example:

    The combination of L-theanine and caffeine improves cognitive performance and increases subjective alertness

    But as it turns out, when a group of researchers actually checked… This isn’t true, as Foxe et al. write:

    ❝We asked whether either compound alone, or both in combination, would affect performance of the task in terms of reduced error rates over time, and whether changes in alpha-band activity would show a relationship to such changes in performance. When treated with placebo, participants showed a rise in error rates, a pattern that is commonly observed with increasing time-on-task, whereas after caffeine and theanine ingestion, error rates were significantly reduced. The combined treatment did not confer any additional benefits over either compound alone, suggesting that the individual compounds may confer maximal benefits at the dosages employed❞

    See: Assessing the effects of caffeine and theanine on the maintenance of vigilance during a sustained attention task

    It promotes a calmly wakeful feeling of serenity

    Those are not words typically found in biopharmaceutical literature, but they’re useful here to convey:

    • L-theanine promotes relaxation without causing drowsiness
    • L-theanine promotes mental alertness without being a stimulant

    Here is where l-theanine really stands out from caffeine. If both substances promote mental focus, but one of them does it by making us “wired” and the other does it while simultaneously promoting calm, it makes the choice between them clearer!

    Read more: L-theanine, a natural constituent in tea, and its effect on mental state

    It relieves stress and anxiety

    Building on from the above, but there’s more: l-theanine relieves stress and anxiety in people experiencing stressful situations, without any known harmful side effects… This is something that sets it apart from a lot of anxiolytic (antianxiety) drugs!

    Here’s what a big systematic review of clinical trials had to say:

    Theanine consumption, stress and anxiety in human clinical trials: A systematic review

    L-theanine has other benefits too

    We’ve talked about some of the most popular benefits of l-theanine, and we can’t make this newsletter too long, but research also suggests that it…

    If you’re interested in this topic, we recommend also reading our previous article on l-theanine—pardon that we hadn’t really nailed down our style yet—but there’s a bunch of useful information about how l-theanine makes caffeine “better” in terms of benefits. We also talk dosage, and reference some other studies we didn’t have room to include today!

  • Loaded Mocha Chocolate Parfait

    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.

    Packed with nutrients, including a healthy dose of protein and fiber, these parfait pots can be a healthy dessert, snack, or even breakfast!

    You will need (for 4 servings)

    For the mocha cream:

    • ½ cup almond milk
    • ½ cup raw cashews
    • ⅓ cup espresso
    • 2 tbsp maple syrup
    • 1 tsp vanilla extract

    For the chocolate sauce:

    • 4 tbsp coconut oil, melted
    • 2 tbsp unsweetened cocoa powder
    • 1 tbsp maple syrup
    • 1 tsp vanilla extract

    For the other layers:

    • 1 banana, sliced
    • 1 cup granola, no added sugar

    Garnish (optional): 3 coffee beans per serving

    Note about the maple syrup: since its viscosity is similar to the overall viscosity of the mocha cream and chocolate sauce, you can adjust this per your tastes, without affecting the composition of the dish much besides sweetness (and sugar content). If you don’t like sweetness, the maple syrup be reduced or even omitted entirely (your writer here is known for her enjoyment of very strong bitter flavors and rarely wants anything sweeter than a banana); if you prefer more sweetness than the recipe called for, that’s your choice too.

    Method

    (we suggest you read everything at least once before doing anything)

    1) Blend all the mocha cream ingredients. If you have time, doing this in advance and keeping it in the fridge for a few hours (or even up to a week) will make the flavor richer. But if you don’t have time, that’s fine too.

    2) Stir all the chocolate sauce ingredients together in a small bowl, and set it aside. This one should definitely not be refrigerated, or else the coconut oil will solidify and separate itself.

    3) Gently swirl the the mocha cream and chocolate sauce together. You want a marble effect, not a full mixing. Omit this step if you want clearer layers.

    4) Assemble in dessert glasses, alternating layers of banana, mocha chocolate marble mixture (or the two parts, if you didn’t swirl them together), and granola.

    5) Add the coffee-bean garnish, if using, and serve!

    Enjoy!

    There’s a lot more to one’s circadian rhythm than just when one wakes and sleeps. This book goes into that quite deeply!

    For example, those items in the subtitle? You could do them all at the same time, but it probably wouldn’t be optimal (although honestly, that does sound like quite a good life!). Rather, there are distinct times of day that we’re going to be better at certain things, and there are distinct times of day when certain things are going to be better for us.

    Of course, some items are not so simple as a one-size fits all, so Dr. Breus outlines for us how to figure out our own chronotype (within four main schemas), and how to make that work for us as well as possible.

    They style is easy-reading pop-science, with frequent summaries, bullet-points, quizzes, and so forth, making it easy to understand, learn, and apply.

    Bottom line: if you feel like your sleep could use a do-over, then this book can help you get it into order—and the rest of your daily activities too!

  • Strawberries vs Cherries – Which is Healthier?

    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 Verdict

    When comparing strawberries to cherries, we picked the cherries.

    Why?

    Both are great, and an argument could be made for either! But here’s our rationale:

    In terms of macros, as with most fruits they are both mostly water, and have similar carbs and fiber. Nominally, cherries have the lower glycemic index, so we could call this category nominally a win for cherries, but honestly, they’re both low-GI foods and nobody is getting metabolic disease from eating strawberries, so it’s fairer to consider this category a tie.

    Looking at the vitamins, strawberries have more of vitamins C, B9, E, and K, while cherries have more of vitamins A, B1, B2, B3, B5, and choline. Thus, a modest win for cherries here.

    When it comes to minerals, strawberries see their day: strawberries have more iron, magnesium, manganese, and phosphorus, while cherries have more calcium, copper, and potassium. By the numbers, a win for strawberries.

    So far, so tied!

    What swings it into cherries’ favor is cherries’ slew of specific phytochemical benefits, including cherry-specific anti-inflammatory properties, sleep-improving abilities, and post-exercise recovery boosts, as well as anti-diabetic benefits above and beyond the normal “this is a fruit” level.

    In short, both are very respectable fruits, but cherries have some extra qualities that are just special.

    Of course, as ever, enjoy either or both; diversity is good!

  • Anti-Inflammatory Cookbook for Beginners – by Melissa Jefferson

    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.

    For some of us, avoiding inflammatory food is a particularly important consideration. For all of us, it should be anyway.

    Sometimes, we know what’s good against inflammation, and we know what’s bad for inflammation… but we might struggle to come up with full meals of just-the-good, especially if we want to not repeat meals every day!

    The subtitle is slightly misleading! It says “Countless Easy and Delicious Recipes”, but this depends on your counting ability. Melissa Jefferson gives us 150 anti-inflammatory recipes, which can be combined for a 12-week meal plan. We think that’s enough to at least call it “many”, though.

    First comes an introduction to inflammation, inflammatory diseases, and a general overview of what to eat / what to avoid. After that, the main part of the book is divided into sections:

    • Breakfasts (20)
    • Soups (15)
    • Beans & Grains (20)
    • Meat (20)
    • Fish (20)
    • Vegetables (20)
    • Sides (15)
    • Snacks (10)
    • Desserts (10)

    If you’ve a knowledge of anti-inflammation diet already, you may be wondering how “Meat” and “Desserts” works.

    • The meat section is a matter of going light on the meat and generally favoring white meats, and certainly unprocessed.
    • Of course, if you are vegetarian or vegan, substitutions may be in order anyway.

    As for the dessert section? A key factor is that fruits and chocolate are anti-inflammatory foods! Just a matter of not having desserts full of sugar, flour, etc.

    The recipes themselves are simple and to-the-point, with ingredients, method, and nutritional values. Just the way we like it.

    All in all, a fine addition to absolutely anyone’s kitchen library… And doubly so if you have a particular reason to focus on avoiding/reducing inflammation!

  • How to be kind to yourself (without going to a day spa)

    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.

    “I have to be hard on myself,” Sarah told me in a recent telehealth psychology session. “I would never reach my potential if I was kind and let myself off the hook.”

    I could empathise with this fear of self-compassion from clients such as Sarah (not her real name). From a young age, we are taught to be kind to others, but self-kindness is never mentioned.

    Instead, we are taught success hinges on self-sacrifice. And we need a healthy inner critic to bully us forward into becoming increasingly better versions of ourselves.

    But research shows there doesn’t have to be a trade-off between self-compassion and success.

    Self-compassion can help you reach your potential, while supporting you to face the inevitable stumbles and setbacks along the way.

    What is self-compassion?

    Self-compassion has three key ingredients.

    1. Self-kindness

    This involves treating yourself with the same kindness you would extend towards a good friend – via your thoughts, feelings and actions – especially during life’s difficult moments.

    For instance, if you find yourself fixating on a minor mistake you made at work, self-kindness might involve taking a ten-minute walk to shift focus, and reminding yourself it is OK to make mistakes sometimes, before moving on with your day.

    2. Mindfulness

    In this context, mindfulness involves being aware of your own experience of stress or suffering, rather than repressing or avoiding your feelings, or over-identifying with them.

    Basically, you must see your stress with a clear (mindful) perspective before you can respond with kindness. If we avoid or are consumed by our suffering, we lose perspective.

    3. Common humanity

    Common humanity involves recognising our own experience of suffering as something that unites us as being human.

    For instance, a sleep-deprived parent waking up (for the fourth time) to feed their newborn might choose to think about all the other parents around the world doing exactly the same thing – as opposed to feeling isolated and alone.

    It’s not about day spas, or booking a manicure

    When Sarah voiced her fear that self-compassion would prevent her success, I explained self-compassion is distinct from self-indulgence.

    “So is self-compassion just about booking in more mani/pedis?” Sarah asked.

    Not really, I explained. A one-off trip to a day spa is unlikely to transform your mental health.

    Instead, self-compassion is a flexible psychological resilience factor that shapes our thoughts, feelings and actions.

    It’s associated with a suite of benefits to our wellbeing, relationships and health.

    What does the science say?

    Over the past 20 years, we’ve learned self-compassionate people enjoy a wide range of benefits. They tend to be happier and have fewer psychological symptoms of distress.

    Those high on self-compassion persevere following a failure. They say they are more motivated to overcome a personal weakness than those low on self-compassion, who are more likely to give up.

    So rather than feeling trapped by your inadequacies, self-compassion encourages a growth mindset, helping you reach your potential.

    However, self-compassion is not a panacea. It will not change your life circumstances or somehow make life “easy”. It is based on the premise that life is hard, and provides practical tools to cope.

    It’s a factor in healthy ageing

    I research menopause and healthy ageing and am especially interested in the value of self-compassion through menopause and in the second half of life.

    Because self-compassion becomes important during life’s challenges, it can help people navigate physical symptoms (for instance, menopausal hot flushes), life transitions such as divorce, and promote healthy ageing.

    I’ve also teamed up with researchers at Autism Spectrum Australia to explore self-compassion in autistic adults.

    We found autistic adults report significantly lower levels of self-compassion than neurotypical adults. So we developed an online self-compassion training program for this at-risk population.

    Three tips for self-compassion

    You can learn self-compassion with these three exercises.

    1. What would you say to a friend?

    Think back to the last time you made a mistake. What did you say to yourself?

    If you notice you’re treating yourself more like an enemy than a friend, don’t beat yourself up about it. Instead, try to think about what you might tell a friend, and direct that same friendly language towards yourself.

    2. Harness the power of touch

    Soothing human touch activates the parasympathetic “relaxation” branch of our nervous system and counteracts the fight or flight response.

    Specifically, self-soothing touch (for instance, by placing both hands on your heart, stroking your forearm or giving yourself a hug) reduces cortisol responses to psychosocial stress.

    Yes, hugging yourself can help.
    http://krakenimages.com/Shutterstock

    3. What do I need right now?

    Sometimes, it can be hard to figure out exactly what self-compassion looks like in a given moment. The question “what do I need right now” helps clarify your true needs.

    For example, when I was 37 weeks pregnant, I woke up bolt awake one morning at 3am.

    Rather than beating myself up about it, or fretting about not getting enough sleep, I gently placed my hands on my heart and took a few deep breaths. By asking myself “what do I need right now?” it became clear that listening to a gentle podcast/meditation fitted the bill (even though I wanted to addictively scroll my phone).The Conversation
