What Your Brain Is Really Doing When You’re Doing “Nothing”

Unless we are dead, our brain is never truly inactive. And it’s not just a matter of regulating autonomic functions, either…
Default Mode Network
When the brain is at rest but not necessarily asleep, the Default Mode Network (DMN) engages. This makes up for around 20% of the brain’s overall activity, and contributes to complex cognitive processes.
What constitutes “at rest”: the DMN activates when external tasks stop and is engaged during self-reflection, mind-wandering, and relaxed memory recall (i.e. reminiscing, rather than answering questions in a difficult test, for example).
As for its neurophysiology, the DMN is connected to the hippocampus and plays a key role in episodic, prospective, and semantic memory (memories of experiences, future plans, and general knowledge), as well as being involved in self-reflection, social cognition, and understanding others’ thoughts (theory of mind). The DMN thus also helps integrate memories and thoughts to create a cohesive internal narrative and sense of self.
However, it doesn’t work alone: the DMN interacts with other networks like the salience network, which switches attention to external stimuli. Disruptions between these networks are linked to psychiatric disorders (e.g., schizophrenia, Alzheimer’s, depression), in various different ways depending on the nature of the disruption.
Sometimes, for some people in some circumstances, the option to disrupt the DMN is useful. For example, research shows that psilocybin disrupts the DMN, leading to changes in brain activity and potential therapeutic benefits for depression* and other psychiatric disorders by enhancing neuroplasticity.
*Essentially, kicking the brain out of the idling gear it got stuck in, and into action

Cashew Nuts vs Coconut – 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 cashew nuts to coconut, we picked the cashews.
Why?
It can be argued this isn’t a fair comparison, as coconuts aren’t true nuts, but it’s at the very least a useful comparison, because they have very similar (often the same) culinary uses, so deciding between one or the other is something people will often do.
In terms of macros, cashews have 6x the protein and more than 2x the fiber, as well as slightly more fat (but the fats are healthy, as are those of coconut, by the way) and 2x the carbs. Depending on what you’re looking for, this head-to-head could come out differently, but we say it’s a win for cashews.
You may be wondering: if cashews have more of all those things, what are coconuts made of? And the answer is that coconuts have 8x the water (and yes, this is counting the coconut meat only, not including the milk inside). Of course, if you get dessicated coconut, then it won’t have that, but we’re comparing fresh to fresh.
In the category of vitamins, cashews have a lot more of vitamins B1, B2, B3, B5, B6, E, and K. Meanwhile, coconut has more vitamin C, but it’s not a lot. An easy win for cashews here.
When it comes to minerals, cashews have rather more calcium, copper, iron, magnesium, manganese, phosphorus, potassium, selenium, and zinc. On the other hand, coconut has more sodium. Another easy win for cashews.
Cashews also have the lower glycemic index.
All in all, cashews win the day.

Nutritional Profiles to Recipes
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.
It’s Q&A Day at 10almonds!
Have a question or a request? We love to hear from you!
In cases where we’ve already covered something, we might link to what we wrote before, but will always be happy to revisit any of our topics again in the future too—there’s always more to say!
As ever: if the question/request can be answered briefly, we’ll do it here in our Q&A Thursday edition. If not, we’ll make a main feature of it shortly afterwards!
So, no question/request too big or small
❝I like the recipes. Most don’t seem to include nutritional profile. would lilke to see that. Macro/micro world…. Thank you❞
We’re glad you’re enjoying them! There are a couple of reasons why we don’t, but the reasons can be aggregated into one (admittedly rare) concept: honesty
To even try to give you these figures, we’d first need to use the metric system (or at least, a strictly mass-based system) which would likely not go well with our largely American readership, because “half a bulb of garlic, or more if you like”, and “1 cucumber” or “1 cup chopped carrot” could easily way half or twice as much, depending on the sizes of the vegetables or the chopping involved, and in the case of chopped vegetables measured by the cup, even the shape of the cup (because of geometry and the spaces left; it’s like Tetris in there). We can say “4 cups low-sodium broth” but we can’t say how much sodium is in your broth. And so on.
And that’s without getting into the flexibility we offer with substitutions, often at a rate of several per recipe.
We’d also need to strictly regulate your portion sizes for you, because we (with few exceptions, such as when they are a given number of burger patties, or a dessert-in-a-glass, etc) give you a recipe for a meal and leave it to you how you divide it and whether there’s leftovers.
Same goes for things like “Extra virgin olive oil for frying”; a recipe could say to use “2 tbsp” but let’s face it, you’re going to use what you need to use, and that’s going to change based on the size of your pan, how quickly it’s absorbed into the specific ingredients that you got, which will change depending on how fresh they are, and things like that.
By the time we’ve factored in your different kitchen equipment, how big your vegetables are, the many factors effecting how much oil you need, substitutions per recipe per making something dairy-free, or gluten-free, or nut-free, etc, how big your portion size is (we all know that “serves 4” is meaningless in reality)… Even an estimated average would be wildly misleading.
So, in a sea of recipes saying “500 kcal per serving” from the same authors who say you can caramelize onions in 4–5 minutes “or until caramelized” and then use the 4–5 minutes figure for calculating the overall recipe time… We prefer to stay honest.
PS: for any wondering, caramelizing onions takes closer to 45 minutes than 4–5 minutes, and again will depend on many factors, including the onions, how finely you chopped them, the size and surface of your pan, the fat you’re using, whether you add sugar, what kind, how much you stir them, the mood of your hob,
and the phase of the moon. Under very favorable circumstances, it could conceivably be rushed in 20 minutes or so, but it could also take 60. Slow-cooking them (i.e. in a crock pot) over 3–4 hours is a surprisingly viable “cheat” option, by the way. It’ll take longer, obviously, but provided you plan in advance, they’ll be ready when you need them, and perfectly done (the same claim cannot be made if you budgeted 4–5 minutes because you trusted a wicked and deceitful author who wants to poop your party).Take care!

‘Sleep tourism’ promises the trip of your dreams. Beyond the hype plus 5 tips for a holiday at home
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.
Imagine arriving at your hotel after a long flight and being greeted by your own personal sleep butler. They present you with a pillow menu and invite you to a sleep meditation session later that day.
You unpack in a room kitted with an AI-powered smart bed, blackout shades, blue light-blocking glasses and weighted blankets.
Holidays are traditionally for activities or sightseeing – eating Parisian pastry under the Eiffel tower, ice skating at New York City’s Rockefeller Centre, lying by the pool in Bali or sipping limoncello in Sicily. But “sleep tourism” offers vacations for the sole purpose of getting good sleep.
The emerging trend extends out of the global wellness tourism industry – reportedly worth more than US$800 billion globally (A$1.2 trillion) and expected to boom.
Luxurious sleep retreats and sleep suites at hotels are popping up all over the world for tourists to get some much-needed rest, relaxation and recovery. But do you really need to leave home for some shuteye?
RossHelen/Shutterstock Not getting enough
The rise of sleep tourism may be a sign of just how chronically sleep deprived we all are.
In Australia more than one-third of adults are not achieving the recommended 7–9 hours of sleep per night, and the estimated cost of this inadequate sleep is A$45 billion each year.
Inadequate sleep is linked to long-term health problems including poor mental health, heart disease, metabolic disease and deaths from any cause.
Can a fancy hotel give you a better sleep?
Many of the sleep services available in the sleep tourism industry aim to optimise the bedroom for sleep. This is a core component of sleep hygiene – a series of healthy sleep practices that facilitate good sleep including sleeping in a comfortable bedroom with a good mattress and pillow, sleeping in a quiet environment and relaxing before bed.
The more people follow sleep hygiene practices, the better their sleep quality and quantity.
When we are staying in a hotel we are also likely away from any stressors we encounter in everyday life (such as work pressure or caring responsibilities). And we’re away from potential nighttime disruptions to sleep we might experience at home (the construction work next door, restless pets, unsettled children). So regardless of the sleep features hotels offer, it is likely we will experience improved sleep when we are away.
Being away from home also means being away from domestic disruptions. Makistock/Shutterstock What the science says about catching up on sleep
In the short-term, we can catch up on sleep. This can happen, for example, after a short night of sleep when our brain accumulates “sleep pressure”. This term describes how strong the biological drive for sleep is. More sleep pressure makes it easier to sleep the next night and to sleep for longer.
But while a longer sleep the next night can relieve the sleep pressure, it does not reverse the effects of the short sleep on our brain and body. Every night’s sleep is important for our body to recover and for our brain to process the events of that day. Spending a holiday “catching up” on sleep could help you feel more rested, but it is not a substitute for prioritising regular healthy sleep at home.
All good things, including holidays, must come to an end. Unfortunately the perks of sleep tourism may end too.
Our bodies do not like variability in the time of day that we sleep. The most common example of this is called “social jet lag”, where weekday sleep (getting up early to get to work or school) is vastly different to weekend sleep (late nights and sleep ins). This can result in a sleepy, grouchy start to the week on Monday. Sleep tourism may be similar, if you do not come back home with the intention to prioritise sleep.
So we should be mindful that as well as sleeping well on holiday, it is important to optimise conditions at home to get consistent, adequate sleep every night.
Good sleep hygiene doesn’t require a passport. Maridav/Shutterstock 5 tips for having a sleep holiday at home
An AI-powered mattress and a sleep butler at home might be the dream. But these features are not the only way we can optimise our sleep environment and give ourselves the best chance to get a good night’s sleep. Here are five ideas to start the night right:
1. avoid bright artificial light in the evening (such as bright overhead lights, phones, laptops)
2. make your bed as comfortable as possible with fresh pillows and a supportive mattress
3. use black-out window coverings and maintain a cool room temperature for the ideal sleeping environment
4. establish an evening wind-down routine, such as a warm shower and reading a book before bed or even a “sleepy girl mocktail”
5. use consistency as the key to a good sleep routine. Aim for a similar bedtime and wake time – even on weekends.

What Your Doctor Wants You to Know to Crush Medical Debt – by Dr. Virgie Ellington
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.
First things first: this one’s really only of relevance to people living in the US. That’s most of our readership, but if it’s not you, then apologies, this one won’t be of interest.
For the US Americans, though, Dr. Ellington starts strong with “you got a bill—now get the right bill”, and then gives a step-by-step process for finding the mistakes in your medical bills, fixing them, dealing with insurers who do not want to live up to their part of the bargain, and how to minimize what you need to pay, when you actually arrive at your final bill.
The biggest strength of this book is the wealth of insider knowledge (the author has worked as a primary care physician as well as as a health insurance executive), and while this information won’t stay current forever, its relatively recent publication date (2022) means that little has changed since then, and once you’re up to speed with how things are now, it’ll be easy to roll with whatever changes may come in the future.
Bottom line: if you’re living in the US and would like to not be ripped off as badly as possible when it comes to healthcare costs, this book is a very small, very powerful, investment.

Intermittent Fasting In Women
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.
It’s Q&A Day at 10almonds!
Have a question or a request? We love to hear from you!
In cases where we’ve already covered something, we might link to what we wrote before, but will always be happy to revisit any of our topics again in the future too—there’s always more to say!
As ever: if the question/request can be answered briefly, we’ll do it here in our Q&A Thursday edition. If not, we’ll make a main feature of it shortly afterwards!
So, no question/request too big or small
❝Does intermittent fasting differ for women, and if so, how?❞
For the sake of layout, we’ve put a shortened version of this question here, but the actual wording was as below, and merits sharing in full for context
Went down a rabbit hole on your site and now can’t remember how I got to the “Fasting Without Crashing” article on intermittent fasting so responding to this email lol, but was curious what you find/know about fasting for women specifically? It’s tough for me to sift through and find legitimate studies done on the results of fasting in women, knowing that our bodies are significantly different from men. This came up when discussing with my sister about how I’ve been enjoying fasting 1-2 days/week. She said she wanted more reliable sources of info that that’s good, since she’s read more about how temporary starvation can lead to long-term weight gain due to our bodies feeling the need to store fat. I’ve also read about that, but also that fasting enables more focused autophagy in our bodies, which helps with long-term staving off of diseases/ailments. Curious to know what you all think!
~ 10almonds subscriber
So, first of all, great question! Thanks for asking it
Next up, isn’t it strange? Books come in the format:
- [title]
- [title, for women]
You would not think women are a little over half of the world’s population!
Anyway, there has been some research done on the difference of intermittent fasting in women, but not much.
For example, here’s a study that looked at 1–2 days/week IF, in other words, exactly what you’ve been doing. And, they did have an equal number of men and women in the study… And then didn’t write down whether this made a difference or not! They recorded a lot of data, but neglected to note down who got what per sex:
Here’s a more helpful study, that looked at just women, and concluded:
❝In conclusion, intermittent fasting could be a nutritional strategy to decrease fat mass and increase jumping performance.
However, longer duration programs would be necessary to determine whether other parameters of muscle performance could be positively affected by IF. ❞
~ Dr. Martínez-Rodríguez et al.
Those were “active women”; another study looked at just women who were overweight or obese (we realize that “active women” and “obese or overweight women” is a Venn diagram with some overlap, but still, the different focus is interesting), and concluded:
❝IER is as effective as CER with regard to weight loss, insulin sensitivity and other health biomarkers, and may be offered as an alternative equivalent to CER for weight loss and reducing disease risk.❞
As for your sister’s specific concern about yo-yoing, we couldn’t find studies for this yet, but anecdotally and based on books on Intermittent Fasting, this is not usually an issue people find with IF. This is assumed to be for exactly the reason you mention, the increased cellular apoptosis and autophagy—increasing cellular turnover is very much the opposite of storing fat!
You might, by the way, like Dr. Mindy Pelz’s “Fast Like A Girl”, which we reviewed previously

Ghanaian Red Bean & Sweet Potato Groundnut Stew
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.
This is a dish popular in principle throughout West Africa. We say “in principle” because that’s a big place, and there is a lot of regional variation. The archetypal peanut stew is from Senegal (as maafe) or Mali (as tigadèguèna), but for its more balanced nutritional profile we’ve chosen one from Ghana—and since there are regional variations within Ghana too, we should specify that this one is from the south.
If you are allergic to nuts, you can substitute a seed butter (or tahini) for the nut butter, and omit the nuts—this will work in culinary terms and be fine healthwise, but we can’t claim it would be the same dish, having lost its defining ingredient. If your allergy is solely to peanuts, then substituting with any oily nut would work. So, not almonds for example, but cashews or even walnuts would be fine.
You will need
- 1½ lbs sweet potatoes, peeled and cut into ½” cubes
- 2 cups low-sodium vegetable stock
- 2 cans kidney beans, drained, cooked, and rinsed (or 2 cups same; cooked, drained, and rinsed)
- 1 can chopped tomatoes
- ½ cup unsalted dry-roasted peanuts
- 1 onion, chopped
- 1 red bell pepper, deseeded and chopped
- ¼ bulb garlic, finely chopped
- 2 heaped tbsp unsalted peanut butter, minimal (ideally: no) additives
- 2 tsp white miso paste
- 2 tsp grated fresh ginger
- 1 tsp ground cumin
- 1 tsp cayenne pepper
- 1 tsp black pepper
- ½ tsp MSG or 1 tsp low-sodium salt
- ½ tsp coarsely ground nigella seeds
- Extra virgin olive oil
Method
(we suggest you read everything at least once before doing anything)
1) Heat some oil in a sauté pan, or other pan suitable for both frying and fitting the entire stew in. Fry the onions until softened, turn the heat down low, and add the garlic, ginger, red bell pepper, cumin, cayenne, black pepper, and MSG/salt.
2) Add ¼ cup of the vegetable stock, and the sweet potato, and turn the heat back up, on high for about 30 seconds to get it to temperature, and then take it down to a simmer.
3) Stir in the miso paste and chopped tomatoes.
4) Add most of the rest of the vegetable stock, keeping ¼ cup aside. Simmer for about 20 minutes.
5) Stir in the kidney beans, and simmer for about 30 minutes more—the sweet potato should be soft now; if it isn’t, let it simmer a while longer until it is.
6) Combine the peanut butter with the remaining ¼ cup vegetable stock, and blend until smooth. Stir it into the stew.
7) If the stew is looking more like a soup than a stew, take out 1 cup and blend this 1 cup to a purée, adding it back in.
8) Add half the peanuts unto the stew. Taste, and adjust the seasonings if necessary.
9) Crush the remaining peanuts using a pestle and mortar; not too much though; you want them broken into bits, not pulverised.
10) Garnish with the crushed nuts and nigella seeds, and serve.
Enjoy!
