The Twenty-Four Hour Mind – by Dr. Rosalind Cartwright

We’ve reviewed books about sleep before, and even about dreaming, so what does this one have to offer that’s new?
Quite a lot, actually! Before Dr. Cartwright, there were mainly two models of sleep and dreaming:
- The “top-down” model of psychoanalysts: our minds shape our dreams which in turn reveal things about us as people
- The “bottom-up” model of neuroscientists: our brains need to go through regular maintaince cycles, of which vivid hallucinations are a quirky side-effect.
And now, as Dr. Cartwright puts it:
❝I will lay out a new [horizontal] psychological model of the twenty-four hour mind; that is, how the predominantly conscious (waking) and unconscious (sleeping) forms of mental behavior interact through the brain’s regular, but differently organized, states of waking, sleeping, and dreaming.❞
This she does in the exploratory style of a 224-page lecture, which sounds like it might be tedious, but is actually attention-grabbing and engaging throughout. This book is more of a page-turner than soporific bedtime reading!
Bottom line: if you’d like to know more about the effect your waking and sleeping brain have on each other (to include getting in between those and making adjutments as appropriate), this is very much an elucidating read!

Q&A with 10almonds Subscribers!
Q: Would love to hear more ideas about effective first thing in the morning time management to get a great start on your day.
A: There are a lot of schools of thought about what’s best in this regard! Maybe we’ll do a main feature sometime. But some things that are almost universally agreed upon are:
- Prepare your to-do list the night before
- Have some sort of buffer between waking up and getting to productivity.
- For me (hi, your writer here) it’s my first coffee of the day. It’s not even about the caffeine, it’s about the ritual of it, it’s a marker that separates my night from the day and tells my brain what gear to get into.
- Others may like to exercise first thing in the morning
- For still yet others, it could be a shower, cold or otherwise
- Some people like a tall glass of lemon water to rehydrate after sleeping!
- If you take drinkable morning supplements such as this pretty awesome nootropic stack, it’s a great time for that and an excellent way to get the brain-juices flowing!
- When you do get to productivity: eat the frog first! What this means is: if eating a frog is the hardest thing you’ll have to do all day, do that first. Basically, tackle the most intimidating task first. That way, you won’t spend your day stressed/anxious and/or subconsciously wasting time in order to procrastinate and avoid it.
- Counterpart to the above: a great idea is to also plan something to look forward to when your working day is done. It doesn’t matter much what it is, provided it’s rewarding to you, that makes you keen to finish your tasks to get to it.

The “Five Tibetan Rites” & Why To Do Them!
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.
Spinning Around
In Tuesday’s newsletter, we asked you for your opinion of the “Five Tibetan Rites”, and got the above-depicted, below-described, set of responses:
- About 41% said “I have never heard of these before”
- About 27% said “they restore youth by adjusting internal vortexes”
- About 22% said “they are basically yoga, by a different name”
- About 11% said “they are a pseudoscience popular in the US”
So what does the science say?
The Five Tibetan Rites are five Tibetan rites: True or False?
False, though this is more question of social science than of health science, so we’ll not count it against them for having a misleading name.
The first known mentioning of the “Five Tibetan Rites” is by an American named Peter Kelder, who in 1939 published, through a small LA occult-specialized publishing house, a booklet called “The Eye of Revelation”. This work was then varyingly republished, repackaged, and occasionally expanded upon by Kelder or other American authors, including Chris Kilham’s popular 1994 book “The Five Tibetans”.
The “Five Tibetan Rites” are unknown as such in Tibet, except for what awareness of them has been raised by people asking about them in the context of the American phenomenon.
Here’s a good history book, for those interested:
The author didn’t originally set out to “debunk” anything, and is himself a keen spiritualist (and practitioner of the five rites), but he was curious about the origins of the rites, and ultimately found them—as a collection of five rites, and the other assorted advices given by Kelder—to be an American synthesis in the whole, each part inspired by various different physical practices (some of them hatha yoga, some from the then-popular German gymnastics movement, some purely American spiritualism, all available in books that were popular in California in the early 1900s).
You may be wondering: why didn’t Kelder just say that, then, instead of telling stories of an ancient Tibetan tradition that empirically does not exist? The answer to this lies again in social science not health science, but it’s been argued that it’s common for Westerners to “pick ‘n’ mix” ideas from the East, champion them as inscrutably mystical, and (since they are inscrutable) then simply decide how to interpret and represent them. Here’s an excellent book on this, if you’re interested:
(in Kelder’s case, this meant that “there’s a Tibetan tradition, trust me” was thus more marketable in the West than “I read these books in LA”)
They are at least five rites: True or False?
True! If we use the broad definition of “rite” as “something done repeatedly in a solemn fashion”. And there are indeed five of them:
- Spinning around (good for balance)
- Leg raises (this one’s from German gymnastics)
- Kneeling back bend (various possible sources)
- Tabletop (hatha yoga, amongst others)
- Pendulum (hatha yoga, amongst others) ← you may recognize this one from the Sun Salutation
You can see them demonstrated here:

Kelder also advocated for what was basically the Hay Diet (named not for the substance but for William Hay; it involved separating foods into acid and alkali, not necessarily according to the actual pH of the foods, and combining only “acid” foods or only “alkali” foods at a time), which was popular at the time, but has since been rejected as without scientific merit. Kelder referred to this as “the sixth rite”.
The Five Rites restore youth by adjusting internal vortexes: True or False?
False, in any scientific sense of that statement. Scientifically speaking, the body does not have vortexes to adjust, therefore that is not the mechanism of action.
Spiritually speaking, who knows? Not us, a humble health science publication.
The Five Rites are a pseudoscience popular in the US: True or False?
True, if 27% of those who responded of our mostly North American readership can be considered as representative of what is popular.
However…
“Pseudoscience” gets thrown around a lot as a bad word; it’s often used as a criticism, but it doesn’t have to be. Consider:
A small child who hears about “eating the rainbow” and mistakenly understands that we are all fuelled by internal rainbows that need powering-up by eating fruits and vegetables of different colors, and then does so…
…does not hold a remotely scientific view of how things are happening, but is nevertheless doing the correct thing as recommended by our best current science.
It’s thus a little similar with the five rites. Because…
The Five Rites are at least good for our health: True or False?
True! They are great for the health.
The first one (spinning around) is good for balance. Science would recommend doing it both ways rather than just one way, but one is not bad. It trains balance, trains our stabilizing muscles, and confuses our heart a bit (in a good way).
See also: Fall Special (How To Not Fall, And Not Get Injured If You Do)
The second one (leg raises) is excellent for core strength, which in turn helps keep our organs where they are supposed to be (this is a bigger health issue than most people realise, because “out of sight, out of mind”), which is beneficial for many aspects of our health!
See also: Visceral Belly Fat & How To Lose It ← visceral fat is the fat that surrounds your internal organs; too much there becomes a problem!
The third, fourth, and fifth ones stretch our spine (healthily), strengthen our back, and in the cases of the fourth and fifth ones, are good full-body exercises for building strength, and maintaining muscle mass and mobility.

So in short…
If you’ve been enjoying the Five Rites, by all means keep on doing them; they might not be Tibetan (or an ancient practice, as presented), and any mystical aspect is beyond the scope of our health science publication, but they are great for the health in science-based ways!
Take care!

Things Many People Forget When It Comes To Hydration
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.
Good hydration is about more than just “drink lots of water”, and in fact it’s quite possible for a person to drink too much water, and at the same time, be dehydrated. Here’s how and why and what to do about it:
Water, water, everywhere
Factors that people forget:
- Electrolyte balance: without it, we can technically have lots of water while either retaining it (in the case of too high salt levels) or peeing it out (in the case of too low salt levels), neither of which are as helpful as getting it right and actually being able to use the water.
- Gastrointestinal health: conditions like IBS, Crohn’s, or celiac disease can impair water and nutrient absorption, affecting hydration
- Genetic factors: some people simply have a predisposition to need more or less water for proper hydration
- Dietary factors: high salt, caffeine, and alcohol intake (amongst other diuretics) can increase water loss, while water-rich foods (assuming they aren’t also diuretics) increase hydration.
Strategies to do better:
- Drink small amounts of water consistently throughout the day rather than large quantities at once—healthy kidneys can process about 1 liter (about 1 quart) of water per hour, so drinking more than that will not help, no matter how dehydrated you are when you start. If your kidneys aren’t in peak health, the amount processable per hour will be lower for you.
- Increase fiber intake (e.g., fruit and vegetables) to retain water in the intestines and improve hydration
- Consume water-rich foods (e.g., watermelon, cucumbers, grapes) to enhance overall hydration and support cellular function (the body can use this a lot more efficiently than if you just drink water).
- Counteract the diuretic effects of caffeine and alcohol by drinking an additional 12 oz of water for every 8 oz of these beverages. Best yet, don’t drink alcohol and keep caffeine to a low level (or quit entirely, if you prefer, but for most people that’s not necessary).
- If you are sweating (be it because of weather, exercise, or any other reasons), include electrolyte fluids to improve cellular hydration, as they contain essential minerals like magnesium, potassium, and in moderation yes even sodium which you will have lost in your sweat too, supporting fluid regulation.

For women with antenatal depression, micronutrients might help them and their babies – new study

Antenatal depression affects 15% to 21% of pregnant women worldwide. It can influence birth outcomes and children’s development, as well as increase the risk of post-natal depression.
Current treatments like therapy can be inaccessible and antidepressants can carry risks for developing infants.
Over the past two decades, research has highlighted that poor nutrition is a contributing risk factor to mental health challenges. Most pregnant women in New Zealand aren’t adhering to nutritional guidelines, according to a longitudinal study. Only 3% met the recommendations for all food groups.
Another cohort study carried out in Brazil shows that ultra-processed foods (UPF) accounted for at least 30% of daily dietary energy during pregnancy, displacing healthier options.
UPFs are chemically manufactured and contain additives to improve shelf life, as well as added sugar and salt. Importantly, they are low in essential micronutrients (vitamins and minerals).
The consumption of these foods is concerning because a nutrient-poor diet during pregnancy has been linked to poorer mental health outcomes in children. This includes depression, anxiety, hyperactivity, and inattention.
Increasing nutrients in maternal diets and reducing consumption of UPFs could improve the mental health of the mother and the next generation. Good nutrition can have lifelong benefits for the offspring.
However, there are multiple factors that mean diet change alone may not in itself be sufficient to address mental health challenges. Supplementing with additional nutrients may also be important to address nutritional needs during pregnancy.
Micronutrients as treatment for depression
Our earlier research suggests micronutrient supplements for depression have benefits outside pregnancy.
But until now there have been no published randomised controlled trials specifically designed to assess the efficacy and safety of broad-spectrum micronutrients on antenatal depression and overall functioning.
The NUTRIMUM trial, which ran between 2017 and 2022, recruited 88 women in their second trimester of pregnancy who reported moderate depressive symptoms. They were randomly allocated to receive either 12 capsules (four pills, three times a day) of a broad-spectrum micronutrient supplement or an active placebo containing iodine and riboflavin for a 12-week period.
Micronutrient doses were generally between the recommended dietary allowance and the tolerable upper level.
Based on clinician ratings, micronutrients significantly improved overall psychological functioning compared to the placebo. The findings took into account all noted changes based on self-assessment and clinician observations. This includes sleep, mood regulation, coping, anxiety and side effects.
Adding micronutrients to the diet of pregnant women with antenatal depression significantly improved their overall psychological functioning. Getty Images Both groups reported similar reductions in symptoms of depression. More than three quarters of participants were in remission at the end of the trial. But 69% of participants in the micronutrient group rated themselves as “much” or “very much” improved, compared to 39% in the placebo group.
Participants taking the micronutrients also experienced significantly greater improvements in sleep and overall day-to-day functioning, compared to participants taking the placebo. There were no group differences on measures of stress, anxiety and quality of life.
Importantly, there were no group differences in reported side effects, and reports of suicidal thoughts dropped over the course of the study for both groups. Blood tests confirmed increased vitamin levels (vitamin C, D, B12) and fewer deficiencies in the micronutrient group.
Micronutrients were particularly helpful for women with chronic mental health challenges and those who had taken psychiatric medications in the past. Those with milder symptoms improved with or without the micronutrients, suggesting general care and monitoring might suffice for some women.
The benefits of micronutrients were comparable to psychotherapy but with less contact. There are no randomised controlled trials of antidepressant medication to compare these results.
Retention in the study was good (81%) and compliance excellent (90%).
Beyond maternal mental health
We followed the infants of mothers enrolled in the NUTRIMUM trial (who were therefore exposed to micronutrients during pregnancy) for 12 months, alongside infants from the general population of Aotearoa New Zealand.
This second group of infants from the general population contained a smaller sub-group who were exposed to antidepressant medication for the treatment of antenatal depression.
We assessed the neuro-behavioural development of each infant within the first four weeks of life, and temperament up to one year after birth.
These observational follow-ups showed positive effects of micronutrients on the infants’ ability to regulate their behaviour. These results were on par with or better than typical pregnancies, and better than treatments with antidepressants.
Micronutrients during pregnancy improved the neurological and behavioural development of infants. Getty Images Infants exposed to micronutrients during pregnancy were significantly better at attending to external stimuli. They were also better able to block out external stimuli during sleep. They showed fewer signs of stress and had better muscle tone compared to infants not exposed to micronutrients.
They also displayed greater ability to interact with their environment. They were better at regulating their emotional state and had fewer abnormal muscle reflexes than infants exposed to antidepressant medication in pregnancy.
Reassuringly, micronutrients had no negative impact on infant temperament.
These findings highlight the potential of micronutrients as a safe and effective alternative to traditional medication treatments for antenatal depression.
The prenatal environment sets the foundation for a child’s future. Further investigation into the benefits of micronutrient supplementation would gives us more confidence in their use for other perinatal (from the start of pregnancy to a year after birth) mental health issues. This could provide future generations with a better start to life.

Let’s Bust Some Myths!
It’s too late after puberty, hormones won’t change xyz
While yes, many adult trans people dearly wish they’d been able to medically transition before going through the “wrong” puberty, the truth is that a lot of changes will still occur later… even to “unchangeable” things like the skeleton.
The body is remaking itself throughout life, and hormones tell it how to do that. Some parts are just quicker or slower than others. Also: the skeleton is pulled-on constantly by our muscles, and in a battle of muscle vs bone, muscle will always win over time.
Examples of this include:
- trans men building bigger bones to support their bigger muscles
- trans women getting smaller, with wider hips and a pelvic tilt
Trans people have sporting advantages
Assuming at least a year’s cross-sex hormonal treatment, there is no useful advantage to being trans when engaging in a sport. There are small advantages and disadvantages (which goes for any person’s body, really). For example:
- Trans women will tend to be taller than cis women on average…
- …but that larger frame is now being powered by smaller muscles, because they shrink much quicker than the skeleton.
- Trans men taking T are the only athletes allowed to take testosterone…
- …but they will still often be smaller than their fellow male competitors, for example.
Read: Do Trans Women Athletes Have Advantages? (A rather balanced expert overview, which does also cover trans men)
There’s a trans population explosion; it’s a social contagion epidemic!
Source for figures: The Overall Rate Of Left-Handedness (Researchgate)
Left-handed people used to make up around 3% of the population… Until the 1920s, when that figure jumped sharply upwards, before plateauing at around 12% in around 1960, where it’s stayed since. What happened?! Simple, schools stopped forcing children to use their right hand.
Today, people ask for trans healthcare because they know it exists! Decades ago, it wasn’t such common knowledge.
The same explanation can be applied to other “population explosions” such as for autism and ADHD.
Fun fact: Mt. Everest was “discovered” in 1852, but scientists suspect it probably existed long before then! People whose ancestors were living on it long before 1852 also agree. Sometimes something exists for a long time, and only comes to wider public awareness later.
Transgender healthcare is too readily available, especially to children!
To believe some press outlets, you’d think:
- HRT is available from school vending machines,
- kids can get a walk-in top surgery at recess,
- and there’s an after-school sterilization club.
In reality, while availability varies from place to place, trans healthcare is heavily gatekept. Even adults have trouble getting it, often having to wait years and/or pay large sums of money… and get permission from a flock of doctors, psychologists, and the like. For those under the age of 18, it’s almost impossible in many places, even with parental support.
Puberty-blockers shouldn’t be given to teenagers, as the effects are irreversible
Quick question: who do you think should be given puberty-blockers? For whom do you think they were developed? Not adults, for sure! They were not developed for trans teens either, but for cis pre-teens with precocious puberty, to keep puberty at bay, to do it correctly later. Nobody argues they’re unsafe for much younger cis children, and only object when it’s trans teens.
They’re not only safe and reversible, but also self-reversing. Stop taking them, and the normally scheduled puberty promptly ensues by itself. For trans kids, the desired effect is to buy the kid time to make an informed and well-considered decision. After all, the effects of the wrong puberty are really difficult to undo!
A lot of people rush medical transition and regret it!
Trans people wish it could be rushed! It’s a lot harder to get gender-affirming care as a trans person, than it is to get the same (or comparable) care as a cis person. Yes, cis people get gender-affirming care, from hormones to surgeries, and have done for a long time.
As for regret… Medical transition has around a 1% regret rate. For comparison, hip replacement has a 4.8% regret rate and knee replacement has a 17.1% regret rate.
A medical procedure with a 99% success rate would generally be considered a miracle cure!
