How to get many benefits of sleep, while awake!
Today we’re talking about Dr. Andrew Huberman, a neuroscientist and professor in the department of neurobiology at Stanford School of Medicine.
He’s also a popular podcaster, and as his Wikipedia page notes:
❝In episodes lasting several hours, Huberman talks about the state of research in a specific topic, both within and outside his specialty❞
Today, we won’t be taking hours, and we will be taking notes from within his field of specialty (neurobiology). Specifically, in this case:
Non-Sleep Deep Rest (NSDR)
What is it? To quote from his own dedicated site on the topic:
❝What is NSDR (Yoga Nidra)? Non-Sleep Deep Rest, also known as NSDR, is a method of deep relaxation developed by Dr. Andrew Huberman, a neuroscientist at Stanford University School of Medicine.
It’s a process that combines controlled breathing and detailed body scanning to bring you into a state of heightened awareness and profound relaxation. The main purpose of NSDR is to reduce stress, enhance focus, and improve overall well-being.❞
While it seems a bit bold of Dr. Huberman to claim that he developed yoga nidra, it is nevertheless reassuring to get a neurobiologist’s view on this:
How it works, by science
Dr. Huberman says that by monitoring EEG readings during NSDR, we can see how the brain slows down. Measurably!
- It goes from an active beta range of 13–30 Hz (normal waking) to a conscious meditation state of an alpha range of 8–13 Hz.
- However, with practice, it can drop further, into a theta range of 4–8 Hz.
- Ultimately, sustained SSDR practice can get us to 0.5–3 Hz.
This means that the brain is functioning in the delta range, something that typically only occurs during our deepest sleep.
You may be wondering: why is delta lower than theta? That’s not how I remember the Greek alphabet being ordered!
Indeed, while the Greek alphabet goes alpha beta gamma delta epsilon zeta eta theta (and so on), the brainwave frequency bands are:
- Gamma = concentrated focus, >30 Hz
- Beta = normal waking, 13–30 Hz
- Alpha = relaxed state, 8–13 Hz
- Theta = light sleep, 4–8 Hz
- Delta = deep sleep, 1–4 Hz
Source: Sleep Foundation ← with a nice infographic there too
NSDR uses somatic cues to engage our parasympathetic nervous system, which in turn enables us to reach those states. The steps are simple:
- Pick a time and place when you won’t be disturbed
- Lie on your back and make yourself comfortable
- Close your eyes as soon as you wish, and now that you’ve closed them, imagine closing them again. And again.
- Slowly bring your attention to each part of your body in turn, from head to toe. As your attention goes to each part, allow it to relax more.
- If you wish, you can repeat this process for another wave, or even a third.
- Find yourself well-rested!
Note: this engagement of the parasympathetic nervous system and slowing down of brain activity accesses restorative states not normally available while waking, but 10 minutes of NSDR will not replace 7–9 hours of sleep; nor will it give you the vital benefits of REM sleep specifically.
So: it’s an adjunct, not a replacement

Switchcraft – by Dr. Elaine Fox
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.
How do we successfully balance “a mind is like a parachute: it only works if it’s open”, with the importance of also actually having some kind of personal integrity and consistency?
Dr. Fox recommends that we focus on four key attributes:
- Mental agility
- Self-awareness
- Emotional awareness
- Situational awareness
If this sounds a little wishy-washy, it isn’t—she delineates and explains each in detail. And most importantly: how we can build and train each one.
Mental agility, for example, is not about being able to rapidly solve chess problems or “answer these riddles three”. It’s more about:
- Adaptability
- Balancing our life
- Challenging (and if appropriate, changing) our perspective
- Developing our mental competence
This sort of thing is the “meat” of the book. Meanwhile, self-awareness is more a foundational conscious knowledge of one’s own “pole star” values, while emotional awareness is a matter of identifying and understanding and accepting what we feel—anything less is self-sabotage! And situational awareness is perhaps most interesting:
Dr. Fox advocates for “trusting one’s gut feelings”. With a big caveat, though!
If we trust our gut feelings without developing their accuracy, we’re just going to go about being blindly prejudiced and often wrong. So, a whole section of the book is devoted to honing this and improving our ability to judge things as they really are—rather than as we expect.
Bottom line: this book is a great tool for not only challenging our preconceptions about how we think, but giving us the resources to be adaptable and resilient without sacrificing integrity.

Women spend more of their money on health care than men. And no, it’s not just about ‘women’s issues’
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.
Medicare, Australia’s universal health insurance scheme, guarantees all Australians access to a wide range of health and hospital services at low or no cost.
Although access to the scheme is universal across Australia (regardless of geographic location or socioeconomic status), one analysis suggests women often spend more out-of-pocket on health services than men.
Other research has found men and women spend similar amounts on health care overall, or even that men spend a little more. However, it’s clear women spend a greater proportion of their overall expenditure on health care than men. They’re also more likely to skip or delay medical care due to the cost.
So why do women often spend more of their money on health care, and how can we address this gap?
Elizaveta Galitckaia/Shutterstock Women have more chronic diseases, and access more services
Women are more likely to have a chronic health condition compared to men. They’re also more likely to report having multiple chronic conditions.
While men generally die earlier, women are more likely to spend more of their life living with disease. There are also some conditions which affect women more than men, such as autoimmune conditions (for example, multiple sclerosis and rheumatoid arthritis).
Further, medical treatments can sometimes be less effective for women due to a focus on men in medical research.
These disparities are likely significant in understanding why women access health services more than men.
For example, 88% of women saw a GP in 2021–22 compared to 79% of men.
As the number of GPs offering bulk billing continues to decline, women are likely to need to pay more out-of-pocket, because they see a GP more often.
In 2020–21, 4.3% of women said they had delayed seeing a GP due to cost at least once in the previous 12 months, compared to 2.7% of men.
Data from the Australian Bureau of Statistics has also shown women are more likely to delay or avoid seeing a mental health professional due to cost.
Women are more likely to live with chronic medical conditions than men. Drazen Zigic/Shutterstock Women are also more likely to need prescription medications, owing at least partly to their increased rates of chronic conditions. This adds further out-of-pocket costs. In 2020–21, 62% of women received a prescription, compared to 37% of men.
In the same period, 6.1% of women delayed getting, or did not get prescribed medication because of the cost, compared to 4.9% of men.
Reproductive health conditions
While women are disproportionately affected by chronic health conditions throughout their lifespan, much of the disparity in health-care needs is concentrated between the first period and menopause.
Almost half of women aged over 18 report having experienced chronic pelvic pain in the previous five years. This can be caused by conditions such as endometriosis, dysmenorrhoea (period pain), vulvodynia (vulva pain), and bladder pain.
One in seven women will have a diagnosis of endometriosis by age 49.
Meanwhile, a quarter of all women aged 45–64 report symptoms related to menopause that are significant enough to disrupt their daily life.
All of these conditions can significantly reduce quality of life and increase the need to seek health care, sometimes including surgical treatment.
Of course, conditions like endometriosis don’t just affect women. They also impact trans men, intersex people, and those who are gender diverse.
Diagnosis can be costly
Women often have to wait longer to get a diagnosis for chronic conditions. One preprint study found women wait an average of 134 days (around 4.5 months) longer than men for a diagnosis of a long-term chronic disease.
Delays in diagnosis often result in needing to see more doctors, again increasing the costs.
Despite affecting about as many people as diabetes, it takes an average of between six-and-a-half to eight years to diagnose endometriosis in Australia. This can be attributed to a number of factors including society’s normalisation of women’s pain, poor knowledge about endometriosis among some health professionals, and the lack of affordable, non-invasive methods to accurately diagnose the condition.
There have been recent improvements, with the introduction of Medicare rebates for longer GP consultations of up to 60 minutes. While this is not only for women, this extra time will be valuable in diagnosing and managing complex conditions.
But gender inequality issues still exist in the Medicare Benefits Schedule. For example, both pelvic and breast ultrasound rebates are less than a scan for the scrotum, and no rebate exists for the MRI investigation of a woman’s pelvic pain.
Management can be expensive too
Many chronic conditions, such as endometriosis, which has a wide range of symptoms but no cure, can be very hard to manage. People with endometriosis often use allied health and complementary medicine to help with symptoms.
On average, women are more likely than men to use both complementary therapies and allied health.
While women with chronic conditions can access a chronic disease management plan, which provides Medicare-subsidised visits to a range of allied health services (for example, physiotherapist, psychologist, dietitian), this plan only subsidises five sessions per calendar year. And the reimbursement is usually around 50% or less, so there are still significant out-of-pocket costs.
In the case of chronic pelvic pain, the cost of accessing allied or complementary health services has been found to average A$480.32 across a two-month period (across both those who have a chronic disease management plan and those who don’t).
More spending, less saving
Womens’ health-care needs can also perpetuate financial strain beyond direct health-care costs. For example, women with endometriosis and chronic pelvic pain are often caught in a cycle of needing time off from work to attend medical appointments.
Our preliminary research has shown these repeated requests, combined with the common dismissal of symptoms associated with pelvic pain, means women sometimes face discrimination at work. This can lead to lack of career progression, underemployment, and premature retirement.
More women are prescribed medication than men. PeopleImages.com – Yuri A/Shutterstock Similarly, with 160,000 women entering menopause each year in Australia (and this number expected to increase with population growth), the financial impacts are substantial.
As many as one in four women may either shift to part-time work, take time out of the workforce, or retire early due to menopause, therefore earning less and paying less into their super.
How can we close this gap?
Even though women are more prone to chronic conditions, until relatively recently, much of medical research has been done on men. We’re only now beginning to realise important differences in how men and women experience certain conditions (such as chronic pain).
Investing in women’s health research will be important to improve treatments so women are less burdened by chronic conditions.
In the 2024–25 federal budget, the government committed $160 million towards a women’s health package to tackle gender bias in the health system (including cost disparities), upskill medical professionals, and improve sexual and reproductive care.
While this reform is welcome, continued, long-term investment into women’s health is crucial.

Running: Getting Started – by Jeff Galloway
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.
Superficially, running is surely one of the easiest sports to get into, for most people. You put one foot in front of the other, repeat, and pick up the pace.
However, many people do not succeed. They head out of the door (perhaps on January the first), push themselves a little, experience runner’s high, think “this is great”, and the next day wake up with some minor aches and no motivation. This book is here to help you bypass that stage.
Jeff Galloway has quite a series of books, but the others seem derivative of this one. So, what makes this one special?
It’s quite comprehensive; it covers (as the title promises) getting started, setting yourself up for success, finding what level your ability is at safely rather than guessing and overdoing it, and building up from there.
He also talks about what kit you’ll want; this isn’t just about shoes, but even “what to wear when the weather’s not good” and so forth; he additionally shares advice about diet, exercise on non-running days, body maintenance (stretching and strengthening), troubleshooting aches and pains, and running well into one’s later years.
Bottom line: if you’d like to take up running but it seems intimidating (perhaps for reasons you can’t quite pin down), this book will take care of all those things, and indeed get you “up and running”.

Drug companies pay doctors over A$11 million a year for travel and education. Here’s which specialties received the most
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.
Drug companies are paying Australian doctors millions of dollars a year to fly to overseas conferences and meetings, give talks to other doctors, and to serve on advisory boards, our research shows.
Our team analysed reports from major drug companies, in the first comprehensive analysis of its kind. We found drug companies paid more than A$33 million to doctors in the three years from late 2019 to late 2022 for these consultancies and expenses.
We know this underestimates how much drug companies pay doctors as it leaves out the most common gift – food and drink – which drug companies in Australia do not declare.
Due to COVID restrictions, the timescale we looked at included periods where doctors were likely to be travelling less and attending fewer in-person medical conferences. So we suspect current levels of drug company funding to be even higher, especially for travel.
Monster Ztudio/Shutterstock What we did and what we found
Since 2019, Medicines Australia, the trade association of the brand-name pharmaceutical industry, has published a centralised database of payments made to individual health professionals. This is the first comprehensive analysis of this database.
We downloaded the data and matched doctors’ names with listings with the Australian Health Practitioner Regulation Agency (Ahpra). We then looked at how many doctors per medical specialty received industry payments and how much companies paid to each specialty.
We found more than two-thirds of rheumatologists received industry payments. Rheumatologists often prescribe expensive new biologic drugs that suppress the immune system. These drugs are responsible for a substantial proportion of drug costs on the Pharmaceutical Benefits Scheme (PBS).
The specialists who received the most funding as a group were cancer doctors (oncology/haematology specialists). They received over $6 million in payments.
This is unsurprising given recently approved, expensive new cancer drugs. Some of these drugs are wonderful treatment advances; others offer minimal improvement in survival or quality of life.
A 2023 study found doctors receiving industry payments were more likely to prescribe cancer treatments of low clinical value.
Our analysis found some doctors with many small payments of a few hundred dollars. There were also instances of large individual payments.
Why does all this matter?
Doctors usually believe drug company promotion does not affect them. But research tells a different story. Industry payments can affect both doctors’ own prescribing decisions and those of their colleagues.
A US study of meals provided to doctors – on average costing less than US$20 – found the more meals a doctor received, the more of the promoted drug they prescribed.
Pizza anyone? Even providing a cheap meal can influence prescribing. El Nariz/Shutterstock Another study found the more meals a doctor received from manufacturers of opioids (a class of strong painkillers), the more opioids they prescribed. Overprescribing played a key role in the opioid crisis in North America.
Overall, a substantial body of research shows industry funding affects prescribing, including for drugs that are not a first choice because of poor effectiveness, safety or cost-effectiveness.
Then there are doctors who act as “key opinion leaders” for companies. These include paid consultants who give talks to other doctors. An ex-industry employee who recruited doctors for such roles said:
Key opinion leaders were salespeople for us, and we would routinely measure the return on our investment, by tracking prescriptions before and after their presentations […] If that speaker didn’t make the impact the company was looking for, then you wouldn’t invite them back.
We know about payments to US doctors
The best available evidence on the effects of pharmaceutical industry funding on prescribing comes from the US government-run program called Open Payments.
Since 2013, all drug and device companies must report all payments over US$10 in value in any single year. Payment reports are linked to the promoted products, which allows researchers to compare doctors’ payments with their prescribing patterns.
Analysis of this data, which involves hundreds of thousands of doctors, has indisputably shown promotional payments affect prescribing.
Medical students need to know about this. LightField Studios/Shutterstock US research also shows that doctors who had studied at medical schools that banned students receiving payments and gifts from drug companies were less likely to prescribe newer and more expensive drugs with limited evidence of benefit over existing drugs.
In general, Australian medical faculties have weak or no restrictions on medical students seeing pharmaceutical sales representatives, receiving gifts, or attending industry-sponsored events during their clinical training. They also have no restrictions on academic staff holding consultancies with manufacturers whose products they feature in their teaching.
So a first step to prevent undue pharmaceutical industry influence on prescribing decisions is to shelter medical students from this influence by having stronger conflict-of-interest policies, such as those mentioned above.
A second is better guidance for individual doctors from professional organisations and regulators on the types of funding that is and is not acceptable. We believe no doctor actively involved in patient care should accept payments from a drug company for talks, international travel or consultancies.
Third, if Medicines Australia is serious about transparency, it should require companies to list all payments – including those for food and drink – and to link health professionals’ names to their Ahpra registration numbers. This is similar to the reporting standard pharmaceutical companies follow in the US and would allow a more complete and clearer picture of what’s happening in Australia.
Patients trust doctors to choose the best available treatments to meet their health needs, based on scientific evidence of safety and effectiveness. They don’t expect marketing to influence that choice.

Power Plates – by Gena Hamshaw
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.
Superfoods are all well and good, but there are only so many ways one can reasonably include watercress before it starts becoming a chore.
Happily, Gena Hamshaw is here with a hundred single-dish vegan meals, that are not only nutritionally balanced as the subtitle promises, but also, as the title suggests, are nutritional powerhouses too.
In the category of criticism, some ingredients are not so universally available as others. For example, depending on where you live, your local supermarket might not have freekeh, gochujang, or pomegranate molasses.
However, most of the recipes have ingredients that are easy enough to source in any medium-sized supermarket, and for the ones that aren’t, we do recommend ordering the ingredient online and trying something you might not otherwise have experienced—that’s an important thing in life, after all!
Bottom line: if you’d like plant-based meals that are packed full of nutrients and are delicious too, this is a top-tier recipe book.
Click here to check out Power Plates, and enjoy a wide variety of plant-based cuisine!
