A Muscle With A Lot Of Therapeutic Value
First, a quick anatomy primer, so that the rest makes sense. We’re going to be talking about your sternocleidomastoid (SCM) muscle today.
To find it, there are two easy ways:
- look in a mirror, turn your head to one side and it’ll stick out on the opposite side of your neck
- look at this diagram
(we’re going to talk about it in the singular, but you have one on each side)
This muscle is interesting for very many reasons, but what we’re going to focus on today is that massaging/stretching it (correctly!) can benefit several things that are right next to it and/or behind it, namely:
- The tenth cranial nerve
- The eleventh cranial nerve
- The carotid artery
Why do we care about these?
Well, we would die quickly without the first and last of those. However, more practically, massaging each has benefits:
The tenth cranial nerve
This one is also known by its superhero alter-ego name:
The Vagus Nerve (And How You Can Make Use Of It)
The eleventh cranial nerve
This one’s not nearly so critical to life, but it does facilitate most of the motor functions in that general part of the body—including some mechanics of speech production, and maintaining posture of the shoulders/neck/head (which in turn strongly affects presence/absence of certain kinds of headaches).
The carotid artery
We suspect you know what this one does already; it supplies the brain (and the rest of your head, for that matter) with oxygenated blood.
What is useful to know today, is that it can be massaged, via the SCM, in a way that brings about a gentler version of this “one weird trick” to cure a lot of kinds of headaches:
Curing Headaches At Home With Actual Science
How (And Why) To Massage Your SCM
…to relieve many kinds of headache, migraine, eye-ache, and tension or pain the jaw. It’s not a magical cure all so this comes with no promises, but it can and will help with a lot of things.
In few words: turn your ahead away from the side where it hurts (if both, just pick one and then repeat for the other side), and slightly downwards. When your SCM sticks out a bit on the other side, gently pinch and rub it, working from the bottom to the top.
If you prefer videos, here is a demonstration:
How (And Why) To Stretch Your SCM
The above already includes a little stretch, but you can stretch it in a way that specifically stimulates your vagus nerve (this is good for many things).
In few words: stand (or sit) up straight, and interlace your fingers together. Put your hands on the back of your neck, thumbs-downwards, and (keeping your face forward) look to one side with your eyes only, and hold that until you feel the urge to yawn (it’ll probably take between about 3 seconds and 30 seconds). Then repeat on the other side.
If you prefer videos, this one is a very slight variation of what we just described but works the same way:

The Stress-Proof Brain – by Dr. Melanie Greenberg
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 premise of the book is as stated in the subtitle: using mindfulness and neuroplasticity to manage our stress response.
As such, it’s divided into three parts:
- Understanding your stress (and different types of stressors)
- Calming your amygdalae (thus, dealing with your stress response while the stressor is stressing you)
- Moving forward with your prefrontal cortex (and thus, gradually improving automatic stress responses over time, as we learn new, better responses to do automatically)
The content ranges from the neurophysiological to “therapist’s couch” stuff; Dr. Greenberg having her PhD in psychology has prepared her to write both of those different-but-touching fields with equal competence. In-line citations are given throughout, for those who want to look up studies.
The style is direct and informative, with little to no attention given to making it an entertaining read. As a result, it’s information dense (which is good), and/but not necessarily a “couldn’t put it down” page-turner.
Bottom line: if you’d like to improve your ability to deal with stress, this book is as good as any.

What’s the difference between ‘strep throat’ and a sore throat? We’re developing a vaccine for one of 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.
What’s the difference? is a new editorial product that explains the similarities and differences between commonly confused health and medical terms, and why they matter.
It’s the time of the year for coughs, colds and sore throats. So you might have heard people talk about having a “strep throat”.
But what is that? Is it just a bad sore throat that goes away by itself in a day or two? Should you be worried?
Here’s what we know about the similarities and differences between strep throat and a sore throat, and why they matter.
Prostock-studio/Shutterstock How are they similar?
It’s difficult to tell the difference between a sore throat and strep throat as they look and feel similar.
People usually have a fever, a bright red throat and sometimes painful lumps in the neck (swollen lymph nodes). A throat swab can help diagnose strep throat, but the results can take a few days.
Thankfully, both types of sore throat usually get better by themselves.
How are they different?
Most sore throats are caused by viruses such as common cold viruses, the flu (influenza virus), or the virus that causes glandular fever (Epstein-Barr virus).
These viral sore throats can occur at any age. Antibiotics don’t work against viruses so if you have a viral sore throat, you won’t get better faster if you take antibiotics. You might even have some unwanted antibiotic side-effects.
But strep throat is caused by Streptococcus pyogenes bacteria, also known as strep A. Strep throat is most common in school-aged children, but can affect other age groups. In some cases, you may need antibiotics to avoid some rare but serious complications.
In fact, the potential for complications is one key difference between a viral sore throat and strep throat.
Generally, a viral sore throat is very unlikely to cause complications (one exception is those caused by Epstein-Barr virus which has been associated with illnesses such as chronic fatigue syndrome, multiple sclerosis and certain cancers).
But strep A can cause invasive disease, a rare but serious complication. This is when bacteria living somewhere on the body (usually the skin or throat) get into another part of the body where there shouldn’t be bacteria, such as the bloodstream. This can make people extremely sick.
Invasive strep A infections and deaths have been rising in recent years around the world, especially in young children and older adults. This may be due to a number of factors such as increased social mixing at this stage of the COVID pandemic and an increase in circulating common cold viruses. But overall the reasons behind the increase in invasive strep A infections are not clear.
Another rare but serious side effect of strep A is autoimmune disease. This is when the body’s immune system makes antibodies that react against its own cells.
The most common example is rheumatic heart disease. This is when the body’s immune system damages the heart valves a few weeks or months after a strep throat or skin infection.
Around the world more than 40 million people live with rheumatic heart disease and more than 300,000 die from its complications every year, mostly in developing countries.
However, parts of Australia have some of the highest rates of rheumatic heart disease in the world. More than 5,300 Indigenous Australians live with it.
Strep throat is caused by Streptococcus bacteria and can be treated with antibiotics if needed. Kateryna Kon/Shutterstock Why do some people get sicker than others?
We know strep A infections and rheumatic heart disease are more common in low socioeconomic communities where poverty and overcrowding lead to increased strep A transmission and disease.
However, we don’t fully understand why some people only get a mild infection with strep throat while others get very sick with invasive disease.
We also don’t understand why some people get rheumatic heart disease after strep A infections when most others don’t. Our research team is trying to find out.
How about a vaccine for strep A?
There is no strep A vaccine but many groups in Australia, New Zealand and worldwide are working towards one.
For instance, Murdoch Children’s Research Institute and Telethon Kids Institute have formed the Australian Strep A Vaccine Initiative to develop strep A vaccines. There’s also a global consortium working towards the same goal.
Companies such as Vaxcyte and GlaxoSmithKline have also been developing strep A vaccines.
What if I have a sore throat?
Most sore throats will get better by themselves. But if yours doesn’t get better in a few days or you have ongoing fever, see your GP.
Your GP can examine you, consider running some tests and help you decide if you need antibiotics.

Quercetin Quinoa Probiotic Salad
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 quercetin-rich salad is a bit like a tabbouleh in feel, with half of the ingredients switched out to maximize phenolic and gut-healthy benefits.
You will need
- ½ cup quinoa
- ½ cup kale, finely chopped
- ½ cup flat leaf parsley, finely chopped
- ½ cup green olives, thinly sliced
- ½ cup sun-dried tomatoes, roughly chopped
- 1 pomegranate, peel and pith removed
- 1 preserved lemon, finely chopped
- 1 oz feta cheese or plant-based equivalent, crumbled
- 1 tsp black pepper, coarse ground
- 1 tbsp capers
- 1 tbsp chia seeds
- 1 tbsp extra virgin olive oil
Note: you shouldn’t need salt or similar here, because of the diverse gut-healthy fermented products bringing their own salt with them
Method
(we suggest you read everything at least once before doing anything)
1) Rinse the quinoa, add the tbsp of chia seeds, cook as normal for quinoa (i.e. add hot water, bring to boil, simmer for 15 minutes or so until pearly and tender), carefully (don’t lose the chia seeds; use a sieve) drain and rinse with cold water to cool. Shake off excess water and/or pat dry on kitchen paper if necessary.
2) Mix everything gently but thoroughly.
3) Serve:
Enjoy!

Dr. Greger’s Anti-Aging Eight
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.
Dr. Greger’s Anti-Aging Eight
This is Dr. Michael Greger. We’ve featured him before: Brain Food? The Eyes Have It!
This time, we’re working from his latest book, the excellent “How Not To Age”, which we reviewed all so recently. It is very information-dense, but we’re going to be focussing on one part, his “anti-aging eight”, that is to say, eight interventions he rates the most highly to slow aging in general (other parts of the book pertained to slowing eleven specific pathways of aging, or preserving specific bodily functions against aging, for example).
Without further ado, his “anti-aging eight” are…
- Nuts
- Greens
- Berries
- Xenohormesis & microRNA manipulation
- Prebiotics & postbiotics
- Caloric restriction / IF
- Protein restriction
- NAD+
As you may have noticed, some of these are things might appear already on your grocery shopping list; others don’t seem so “household”. Let’s break them down:
Nuts, greens, berries
These are amongst the most nutrient-dense and phytochemical-useful parts of the diet that Dr. Greger advocates for in his already-famous “Dr. Greger’s Daily Dozen”.
For brevity, we’ll not go into the science of these here, but will advise you: eat a daily portion of nuts, a daily portion of berries, and a couple of daily portions of greens.
Xenohormesis & microRNA manipulation
You might, actually, have these on your grocery shopping list too!
Hormesis, you may recall from previous editions of 10almonds, is about engaging in a small amount of eustress to trigger the body’s self-strengthening response, for example:
Xenohormesis is about getting similar benefits, second-hand.
For example, plants that have been grown to “organic” standards (i.e. without artificial pesticides, herbicides, fertilizers) have had to adapt to their relatively harsher environment by upping their levels of protective polyphenols and other phytochemicals that, as it turns out, are as beneficial to us as they are to the plants:
Hormetic Effects of Phytochemicals on Health and Longevity
Additionally, the flip side of xenohormesis is that some plant compounds can themselves act as a source of hormetic stress that end up bolstering us. For example:
In essence, it’s not just that it has anti-oxidant effect; it also provides a tiny oxidative-stress immunization against serious sources of oxidative stress—and thus, aging.
MicroRNA manipulation is, alas, too complex to truly summarize an entire chapter in a line or two, but it has to do with genetic information from the food that we eat having a beneficial or deleterious effect to our own health:
Diet-derived microRNAs: unicorn or silver bullet?
A couple of quick takeaways (out of very many) from Dr. Greger’s chapter on this is to spring for the better quality olive oil, and skip the cow’s milk:
- Impact of Phenol-Enriched Virgin Olive Oils on the Postprandial Levels of Circulating microRNAs Related to Cardiovascular Disease
- MicroRNA exosomes of pasteurized milk: potential pathogens of Western diseases
Prebiotics & Postbiotics
We’re short on space, so we’ll link you to a previous article, and tell you that it’s important against aging too:
Making Friends With Your Gut (You Can Thank Us Later)
An example of how one of Dr. Greger’s most-recommended postbiotics helps against aging, by the way:
- The mitophagy activator urolithin A is safe and induces a molecular signature of improved mitochondrial and cellular health in humans
- Urolithin A improves muscle strength, exercise performance, and biomarkers of mitochondrial health in a randomized trial in middle-aged adults
(Urolithin can be found in many plants, and especially those containing tannins)
See also: How to Make Urolithin Postbiotics from Tannins
Caloric restriction / Intermittent fasting
This is about lowering metabolic load and promoting cellular apoptosis (programmed cell death; sounds bad; is good) and autophagy (self-consumption; again, sounds bad; is good).
For example, he cites the intermittent fasters’ 46% lower risk of dying in the subsequent years of follow-up in this longitudinal study:
For brevity we’ll link to our previous IF article, but we’ll revisit caloric restriction in a main feature on of these days:
Fasting Without Crashing? We sort the science from the hype!
Dr. Greger favours caloric restriction over intermittent fasting, arguing that it is easier to adhere to and harder to get wrong if one has some confounding factor (e.g. diabetes, or a medication that requires food at certain times, etc). If adhered to healthily, the benefits appear to be comparable for each, though.
Protein restriction
In contrast to our recent main feature Protein vs Sarcopenia, in which that week’s featured expert argued for high protein consumption levels, protein restriction can, on the other hand, have anti-aging effects. A reminder that our body is a complex organism, and sometimes what’s good for one thing is bad for another!
Dr. Greger offers protein restriction as a way to get many of the benefits of caloric restriction, without caloric restriction. He further notes that caloric restriction without protein restriction doesn’t decrease IGF-1 levels (a marker of aging).
However, for FGF21 levels (these are good and we want them higher to stay younger), what matters more than lowering proteins in general is lowering levels of the amino acid methionine—found mostly in animal products, not plants—so the source of the protein matters:
For example, legumes deliver only 5–10% of the methionine that meat does, for the same amount of protein, so that’s a factor to bear in mind.
NAD+
This is about nicotinamide adenine dinucleotide, or NAD+ to its friends.
NAD+ levels decline with age, and that decline is a causal factor in aging, and boosting the levels can slow aging:
Therapeutic Potential of NAD-Boosting Molecules: The In Vivo Evidence
Can we get NAD+ from food? We can, but not in useful quantities or with sufficient bioavailability.
Supplements, then? Dr. Greger finds the evidence for their usefulness lacking, in interventional trials.
How to boost NAD+, then? Dr. Greger prescribes…
Exercise! It boosts levels by 127% (i.e., it more than doubles the levels), based on a modest three-week exercise bike regimen:
Skeletal muscle NAMPT is induced by exercise in humans
Another study on resistance training found the same 127% boost:

What does it mean to be immunocompromised?
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 immune systems help us fight off disease, but certain health conditions and medications can weaken our immune systems. People whose immune systems don’t work as well as they should are considered immunocompromised.
Read on to learn more about how the immune system works, what causes people to be immunocompromised, and how we can protect ourselves and the immunocompromised people around us from illness.
What is the immune system?
The immune system is a network of cells, organs, and chemicals that helps our bodies fight off infections caused by invaders, such as bacteria, viruses, fungi, and parasites.
Some important parts of the immune system include:
- White blood cells, which attack and kill germs that don’t belong inside our bodies.
- Lymph nodes, which help our bodies filter out germs.
- Antibodies, which help our bodies recognize invaders.
- Cytokines, which tell our immune cells what to do.
What causes people to be immunocompromised?
Some health conditions and medications can prevent our immune systems from functioning optimally, which makes us more vulnerable to infection. Health conditions that compromise the immune system fall into two categories: primary immunodeficiency and secondary immunodeficiency.
Primary immunodeficiency
People with primary immunodeficiency are born with genetic mutations that prevent their immune systems from functioning as they should. There are hundreds of types of primary immunodeficiencies. Since these mutations affect the immune system to varying degrees, some people may experience symptoms and get diagnosed early in life, while others may not know they’re immunocompromised until adulthood.
Secondary immunodeficiency
Secondary immunodeficiency happens later in life due to an infection like HIV, which weakens the immune system over time, or certain types of cancer, which prevent the body from producing enough white blood cells to adequately fight off infection. Studies have also shown that getting infected with COVID-19 may cause immunodeficiency by reducing our production of “killer T-cells,” which help fight off infections.
Sometimes necessary treatments for certain medical conditions can also cause secondary immunodeficiency. For example, people with autoimmune disorders—which cause the immune system to become overactive and attack healthy cells—may need to take immunosuppressant drugs to manage their symptoms. However, the drugs can make them more vulnerable to infection.
People who receive organ transplants may also need to take immunosuppressant medications for life to prevent their body from rejecting the new organ. (Given the risk of infection, scientists continue to research alternative ways for the immune system to tolerate transplantation.)
Chemotherapy for cancer patients can also cause secondary immunodeficiency because it kills the immune system’s white blood cells as it’s trying to kill cancer cells.
What are the symptoms of a compromised immune system?
People who are immunocompromised may become sick more frequently than others or may experience more severe or longer-term symptoms than others who contract the same disease.
Other symptoms of a compromised immune system may include fatigue; digestive problems like cramping, nausea, and diarrhea; and slow wound healing.
How can I find out if I’m immunocompromised?
If you think you may be immunocompromised, talk to your health care provider about your medical history, your symptoms, and any medications you take. Blood tests can determine whether your immune system is producing adequate proteins and cells to fight off infection.
I’m immunocompromised—how can I protect myself from infection?
If you’re immunocompromised, take precautions to protect yourself from illness.
Wash your hands regularly, wear a well-fitting mask around others to protect against respiratory viruses, and ensure that you’re up to date on recommended vaccines.
Immunocompromised people may need more doses of vaccines than people who are not immunocompromised—including COVID-19 vaccines. Talk to your health care provider about which vaccines you need.
How can I protect the immunocompromised people around me?
You never know who may be immunocompromised. The best way to protect immunocompromised people around you is to avoid spreading illnesses.
If you know you’re sick, isolate whenever possible. Wear a well-fitting mask around others—especially if you know that you’re sick or that you’ve been exposed to germs. Make sure you’re up to date on recommended vaccines, and practice regular hand-washing.
If you’re planning to spend time with someone who is immunocompromised, ask them what steps you can take to keep them safe.
For more information, talk to your health care provider.

Come As You Are – by Dr. Emily Nagoski
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.
We’ve all heard the jokes, things like: Q: “Why is the clitoris like Antarctica?” A: “Most men know it’s there; most don’t give a damn”
But… How much do people, in general, really know about the anatomy and physiology of sexual function? Usually very little, but often without knowing how little we know.
This book looks to change that. Geared to a female audience, but almost everyone will gain useful knowledge from this.
The writing style is very easy-to-read, and there are “tl;dr” summaries for those who prefer to skim for relevant information in this rather sizeable (400 pages) tome.
Yes, that’s “what most people don’t know”. Four. Hundred. Pages.
We recommend reading it. You can thank us later!
