Lower Your Cortisol! (Here’s Why & How)

Cortisol, or “the stress hormone” to its friends, is produced by your adrenal glands, and is generally considered “not fun”.
It does serve a purpose, of course, just like almost everything else our body does. It serves as part of the “fight or flight” response, for example, and helps you to wake up in the morning.
While you do need some cortisol (and a small percentage of people have too little), most of us have too much.
Why? Simply put, modern life is not what 200,000* years of human evolution prepared us for:
- Agriculture (which allowed us to settle down and cease being nomadic) happened during the last 6% of those 200,000 years.
- The Industrial Revolution and the onset of modern capitalism happened during only during the last 0.1% of those 200,000 years.
*the 200,000 years figure is conservative and doesn’t take into account the 200,000,000 years of pre-hominid mammalian evolution. Doing so, on the basis of the mammalian brain & physiology being what’s important here, means our modern stressors have been around for <0.0001% of the time we have.
So guess what, our bodies haven’t caught up. As far as our bodies are concerned, we are supposed to be enjoying the sunshine of grassy plains and the shade of woodland while eating fruit.
- When the alarm clock goes off, our body panics and prepares us to either flee or help fight the predator, because why else would we have been woken so?
- When we have a pressing deadline for work, our brain processes this as “if we don’t do this, we will literally starve and die”.
- When people are upset or angry with us, there’s a part of our brain that fears exile from the tribe and resultant death.
…and so on.
Health Risks of High Cortisol
The long-term stressors are the biggest issue for health. Unless you have a heart condition or other relevant health problem, almost anyone can weather a brief unpleasant surprise. But if something persists? That prompts the body to try to protect you, bless it. The body’s attempts backfire, because…
- One way it does this by making sure to save as much food as possible in the form of body fat
- It’ll also increase your appetite, to make sure you eat anything you can while you still can
- It additionally tries to protect you by keeping you on the brink of fight-or-flight readiness, e.g:
- High blood pressure
- High blood sugar levels
- Rapid mood changes—gotta be able to do those heel-turns as necessary and react quickly to any possible threat!
Suffice it to say, these things are not good for your long-term health.
That’s the “Why”—now here’s the “How”:
Lowering your cortisol levels mostly means lowering your stress and/or lowering your stress response. We previously gave some powerful tools for lowering anxiety, which for these purposes amounts to the same thing.
However, we can also make nutritional and lifestyle changes that will reduce our cortisol levels, for example:
- Reduce (ideally: eliminate from your lifestyle) caffeine
- Reduce (ideally: eliminate from your lifestyle) alcohol
- Yes, really. While many understandably turn to alcohol specifically to help manage stress, it only makes it worse long-term.
- Additionally, alcohol directly stimulates cortisol production, counterintuitive as that may be.

As well as reductions/eliminations, are some things you can add into your lifestyle that will help!
We’ve written previously about some:

Other things include, no surprises here:
- The Mediterranean diet (nutritious and delicious): https://10almonds.com/mediterranean-diet
- Get 7–9 hours (good quality!) sleep per night: https://10almonds.com/time-pillow-talk
- Get regular exercise (the regularity matters most!): https://10almonds.com/keep-on-keeping-on
Progressive Relaxation
We’ll give this one its own section because we’ve not talked about it before. Maybe you’re familiar. If not, then in a nutshell: progressive relaxation means progressively tensing and then relaxing each part of your body in turn.
Why does this work? Part of it is just a physical trick involving biofeedback and the natural function of muscles to contract and relax in turn, but the other part is even cleverer:
It basically tricks the most primitive part of your brain, the limbic system, into thinking you had a fight and won, telling it “thank you very much for the cortisol but we don’t need it anymore”.
Take a Hike! Or a Stroll… You Do You!
Last but not least: go connect with your roots. Spend time in the park, or at least the garden. Have a picnic, if the weather suits. Go somewhere you can spend time around leafy green things under a blue sky (we realize the blue sky may be subject to availability in some locations, but do what you can!).
Remember also: just as your body’s responses will be tricked by the alarm clock or the housework, they will also be easily tricked by blue and green stuff around you. If a sunny garden isn’t available in your location, a picture of one as your desktop background is the next best thing.

Fall Special
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.
Some fall-themed advice…
It is now, nominally at least, fall. We’re going to talk about the other kind of “fall” though, the kind that results in broken hips and more.
If you’re thinking “not me; that happens to older more infirm people”, rest assured, it can and statistically probably will happen to you at some point. So, how to play the odds?
First, be robust!
We may not be able to make ourselves like children who bounce easily, but we also don’t have to crumble into dust at the slightest knock, either. There are two important ways we can start to make ourselves robust from the inside out, and they are simple: diet and exercise.
- Diet: The Bare-Bones Truth About Osteoporosis
- Exercise: Osteoporosis Exercises
“But I don’t have osteoporosis”—great! But osteoporosis is preceded by osteopenia, which is generally asymptomatic at first, and also if we’re not very careful about it, we will lose about 1% bone density per year from the age of about 35 onwards, with that rate of loss climbing sharply from the age of 50 onwards, and even more steeply in cases of untreated menopause.
So in other words, don’t take your bone strength for granted; there’s a first time for everything, and you don’t want to find out the hard (and yet, dare we say it, brittle) way.
Second, be dynamic!
Be able to fall and get up safely. If your later life is going to be a triathlon of things you need to train for now, then being able to fall and get up safely should be at the top of the list.
Being able to “deep squat” will help you a lot here, in being able to get up with minimal (or no) use of your hands. We shared a great instructional video about this last week.
It also means that the more your lower body can still take your weight while your torso is closer to the ground (without your legs buckling and collapsing, for instance), the softer and gentler you’ll hit the floor if you do fall, because the final “drop” will be from a lower height.
If at all possible, consider taking some classes of a martial art that involves safely falling—aikido is typically the softest and gentlest and is famously great for people of all ages, but judo or jujitsu will suffice if aikido isn’t available where you are. You don’t have to get a black belt (unless you want to), and any decent instructor will be happy to guide you through the basics of safely falling and then send you on your merry way, if that’s all you wanted.
The benefits of this are twofold:
- Obviously, if you fall, you will have better technique and thus be less likely to incur injury
- As you are falling, you will be less afraid, and thus less likely to tense up mid-fall (tensing up will exacerbate any falling injury)

Third, be balanced!
Spending even just a few minutes each day working on your balance can go a long way.
Standing on one leg (and then the other) is a very good obvious starting point. Please, do so safely. The shower is not the best place to take up this practice, for instance. A nice safe grassy area is great. Your carpeted living room or bedroom is next-best.
Another great approach is the practice of bāguàzhǎng circle-walking.
Bāguà is tai chi’s lesser-known cousin, and those arts are two of the three main schools of wǔdāngquán. But, fear not, you don’t have to don orange robes and live atop the Wudang mountains to get what you need in this case.
To give a text-based summary: bāguàzhǎng circle-walking involves walking in a small circle, with a low center of gravity, moving one’s weight very purposefully from one leg to the other, keeping complete stability the whole time that one is (often!) on one leg.
Once you get good at this, you’ll see that this is essentially a super-enhanced version of the “standing on one leg” exercise, because it’s about keeping balance while on one leg, and/but while moving also.
Naturally, if you do get good at this, you’ll be very unlikely to fall in the first place.
Here’s a visual primer. This video will show the basic footwork, and the video that follows it (it’ll prompt you if you want to watch it) shows how to bring it up to a standard walking speed, without losing fluidity of movement:

4 Critical Things Female Runners Should Know

When it comes to keeping up performance in the face of menopause, Shona Hendricks has advice:
Don’t let menopause run you down
- Prioritize recovery! Overtraining without adequate recovery just leads to decreased performance in the long term, and remember, you may not recover as quickly as you used to. If you’re still achey from your previous run, give it another day, or at least make it a lighter run.
- Slow down in easy and long runs! This isn’t “taking the easy way out”; it will improve your overall performance, reducing muscle damage, allowing for quicker recovery and ultimately better fitness gains.
- Focus on nutrition! And that means carbs too. A lot of people fighting menopausal weight gain reduce their intake of food, but without sufficient energy availability, you will not be able to run well. In particular, carbohydrates are vital for energy. Consume them sensibly and with fiber and proteins and fats rather than alone, but do consume them.
- Incorporate strength training! Your run is not “leg day” by itself. Furthermore, do whole-body strength training, to prevent injuries and improve overall performance. A strong core is particularly important.

We looked at over 166,000 psychiatric records. Over half showed people were admitted against their will
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.
Picture two people, both suffering from a serious mental illness requiring hospital admission. One was born in Australia, the other in Asia.
Hopefully, both could be treated on a voluntary basis, taking into account their individual needs, preferences and capacity to consent. If not, you might imagine they should be equally likely to receive treatment against their will (known colloquially as being “sectioned” or “scheduled”).
However, our research published in British Journal of Psychiatry Open suggests this is not the case.
In the largest study globally of its kind, we found Australians are more likely to be treated in hospital for their acute mental illness against their will if they are born overseas, speak a language other than English or are unemployed.
What we did and what we found
We examined more than 166,000 episodes of voluntary and involuntary psychiatric care in New South Wales public hospitals between 2016 and 2021. Most admissions (54%) included at least one day of involuntary care.
Being brought to hospital via legal means, such as by police or via a court order, was strongly linked to involuntary treatment.
While our study does not show why this is the case, it may be due to mental health laws. In NSW, which has similar laws to most jurisdictions in Australia, doctors may treat a person on an involuntary basis if they present with certain symptoms indicating serious mental illness (such as hallucinations and delusions) which cause them to require protection from serious harm, and there is no other less-restrictive care available. Someone who has been brought to hospital by police or the courts may be more likely to meet the legal requirement of requiring protection from serious harm.
The likelihood of involuntary care was also linked to someone’s diagnosis. A person with psychosis or organic brain diseases, such as dementia and delirium, were about four times as likely to be admitted involuntarily compared to someone with anxiety or adjustment disorders (conditions involving a severe reaction to stressors).
However, our data suggest non-clinical factors contribute to the decision to impose involuntary care.
Compared with people born in Australia, we found people born in Asia were 42% more likely to be treated involuntarily.
People born in Africa or the Middle East were 32% more likely to be treated this way.
Overall, people who spoke a language other than English were 11% more likely to receive involuntary treatment compared to those who spoke English as their first language.
Some international researchers have suggested higher rates of involuntary treatment seen in people born overseas might be due to higher rates of psychotic illness. But our research found a link between higher rates of involuntary care in people born overseas or who don’t speak English regardless of their diagnosis.
We don’t know why this is happening. It is likely to reflect a complex interplay of factors about both the people receiving treatment and the way services are provided to them.
People less likely to be treated involuntarily included those who hold private health insurance, and those referred through a community health centre or outpatients unit.
Our findings are in line with international studies. These show higher rates of involuntary treatment among people from Black and ethnic minority groups, and people living in areas of higher socioeconomic disadvantage.
A last resort? Or should we ban it?
Both the NSW and Australian mental health commissions have called involuntary psychiatric care an avoidable harm that should only be used as a last resort.
Despite this, one study found Australia’s rate of involuntary admissions has increased by 3.4% per year and it has one of the highest rates of involuntary admissions in the world.
Involuntary psychiatric treatment is also under increasing scrutiny globally.
When Australia signed up to the UN Convention on the Rights of Persons with Disabilities, it added a declaration noting it would allow for involuntary treatment of people with mental illness where such treatments are “necessary, as a last resort and subject to safeguards”.
However, the UN has rejected this, saying it is a fundamental human right “to be free from involuntary detention in a mental health facility and not to be forced to undergo mental health treatment”.
Others question if involuntary treatment could ever be removed entirely.
Where to from here?
Our research not only highlights concerns regarding how involuntary psychiatric treatment is implemented, it’s a first step towards decreasing its use. Without understanding how and when it is used it will be difficult to create effective interventions to reduce it.
But Australia is still a long way from significantly reducing involuntary treatment.
We need to provide more care options outside hospital, ones accessible to all Australians, including those born overseas, who don’t speak English, or who come from disadvantaged communities. This includes intervening early enough that people are supported to not become so unwell they end up being referred for treatment via police or the criminal justice system.
More broadly, we need to do more to reduce stigma surrounding mental illness and to ensure poverty and discrimination are tackled to help prevent more people becoming unwell in the first place.
Our study also shows we need to do more to respect the autonomy of someone with serious mental illness to choose if they are treated. That’s whether they are in NSW or other jurisdictions.
And legal reform is required to ensure more states and territories more fully reflect the principal that people who have the capacity to make such decisions should have the right to decline mental health treatment in the same way they would any other health care.

Healthy Brain, Happy Life – by Dr. Wendy Suzuki

We talked about Dr. Wendy Suzuki’s research in the category of exercise and brain-benefits in our main feature the other day. But she has more to say than we can fit into an article!
This book chronicles her discoveries, through her work in memory and neuroplasticity, to her discoveries about exercise, and her dive into broader neurology-based mental health. So what does neurology-based mental health look like?
The answer is: mitigating brain-busters such as stress and anxiety, revitalizing a fatigued brain, boosting creativity, and other such benefits.
Does she argue that exercise is a cure-all? No, not quite. Sometimes there are other things she’s recommending (such as in her chapter on challenging the neurobiology of the stress response, or her chapter on meditation and the brain).
The writing style is mostly casual, interspersed with occasional mini-lectures (complete with diagrams and other illustrations), and is very readable and informative throughout.
Bottom line: if you’d like the more in-depth details of Dr. Suzuki’s work, this book is a very accessible way to get 320 pages of that!

Burn! How To Boost Your Metabolism
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.
Let’s burn! Metabolic tweaks and hacks
Our metabolism is, for as long as we live, a constantly moving thing. And it’s not a monolith either; there are parts of our metabolism that can speed up or slow down independently of others.
If we talk about metabolism without clarifying context, though, this is usually about one’s “basal metabolic rate”, that is, how many calories we burn just by being alive.
Why do we want to speed it up? Might we ever want to slow it down?
We might want to slow our metabolism down in survival circumstances, but generally speaking, a faster metabolism is a better one.
Yes, even when it comes to aging. Because although metabolism comes with metabolizing oxygen (which, ironically, tends to kill us eventually, since this is a key part of cellular aging), it is still beneficial to replace cells sooner rather than later. The later we replace a given cell (ie, the longer the cell lives), the more damaged it gets, and then the copy is damaged from the start, because the damage was copied along with it. So, best to have a fast metabolism to replace cells quickly when they are young and healthy.
A quick metabolism helps the body to do this.
Most people, of course, are interested in a fast metabolism to burn off fat, but beware: if you increase your metabolism without consideration to how and when you consume calories, you will simply end up eating more to compensate.
One final quick note before we begin:
Limitations
There’s a lot we can do to change our metabolism, but there are some things that may be outside of our control. They include:
- Age—we can influence our biological age, but we cannot (yet!) halt aging, so this will happen
- Body size—and yes we can change this a bit, but we all have our own “basic frame” to work with. Someone who is 6’6” is never going to be able to have the same lower-end-of-scale body mass of someone who is 5’0”, say.
- Sex—this is about hormones, and HRT is a thing, but for example, broadly speaking, men will have faster metabolisms than women, because of hormonal differences.
- Medical conditions—often also related to other hormones, but for example someone with Type 1 Diabetes is going to have a very different relationship with their metabolism than someone without, and someone with a hypo- or hyperactive thyroid will again have a very different metabolism in a way that that lifestyle factors can’t completely compensate for.
The tips and tricks
Intermittent fasting
Intermittent fasting has been found to, amongst other things, promote healthy apoptosis and autophagy (in other words: early programmed cell death and recycling—these are good things).
It also has anti-inflammatory benefits and decreases the risk of insulin resistance. In other words, intermittent fasting boosts the metabolism while simultaneously guarding against some of the dangers of a faster metabolism (harms you’d get if you instead increased your metabolism by doing intense exercise and then eating a mountain of convenience food to compensate)
Read the science: Intermittent Fasting: Is the Wait Worth the Weight?
Read our prior article: Fasting Without Crashing? We Sort The Science From The Hype
Enjoy plenty of protein
This one won’t speed your metabolism up, so much as help it avoid slowing down as a result of fat loss.
Because of our body’s marvelous homeostatic system trying to keep our body from changing status at any given time, often when we lose fat, our body drops our metabolism to compensate, thinking we are in an ongoing survival situation and food is scarce so we’d better conserve energy (as fat). That’s a pain for would-be weight-loss dieters!
Eating protein can let our body know that we’re perfectly safe and not starving, so it will keep the metabolism ticking over nicely, without putting on fat.
Read the science: The role of protein in weight loss and maintenance
Stay hydrated
People think of drinking water as part of a weight loss program being just about filling oneself up, and that is a thing, but it also has a role to play in our metabolism. Specifically, lipolysis (the process of removing fat).
Because, we are mostly water. Not only is it the main content of our various body tissue cells, but also, of particular note, our blood (the means by which everything is transported around our body) is mostly water, too.
It’s hard for the body to keep everything ticking over like a well-oiled machine if its means of transportation is sluggish!
Check it out: Increased Hydration Can Be Associated with Weight Loss
Take a stand
That basal metabolic rate we talked about?
- If you’re lying down at rest, that’s what your metabolism will be like.
- If you’re sitting up, it’ll be a little quicker, but not much.
- If you’re standing, suddenly half your body is doing things, and you don’t even notice them because they’re just stabilizing muscles and the like, but on a cellular level, your body gets very busy.
Read all about it: Cardiometabolic impact of changing sitting, standing, and stepping in the workplace
Time to invest in a standing desk? Or a treadmill in front of the TV?
The spice of life
Capsaicin, the compound in many kinds of pepper that give them their spicy flavor, boosts the metabolism. In the words of Tremblay et al for the International Journal of Obesity:
❝[Capsaicin] stimulates the sympathoadrenal system that mediates the thermogenic and anorexigenic effects of capsaicinoids.
Capsaicinoids have been found to accentuate the impact of caloric restriction on body weight loss.
Some studies have also shown that capsinoids increase energy expenditure.
Capsaicin supplementation attenuates or even prevents the increase in hunger and decrease in fullness as well as the decrease in energy expenditure and fat oxidation, which normally result from energy restriction❞
Read for yourself: Capsaicinoids: a spicy solution to the management of obesity?
You snooze, you lose (fat)
While exercising is generally touted as the road to weight loss, and certainly regular exercise does have a part to play, doing so without good rest will have bad results.
In fact, even if you’re not exercising, if you don’t get enough sleep your metabolism will get sluggish to try to slow you down and encourage you to sleep.
So, be proactive, and make getting enough good quality sleep a priority.
Eat for metabolic health
Aside from the chilli peppers we mentioned, there are other foods associated with good metabolic health. We don’t have room to go into the science of each of them here, but here’s a well-researched, well-sourced standalone article listing some top choices:

Broccoli vs Asparagus – 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 broccoli to asparagus, we picked the broccoli.
Why?
Both are great! But broccoli does distinguish itself:
In terms of macros, broccoli has slightly more protein, carbs, and fiber. The two vegetables have the same glycemic index. We’ll call this a slight win for broccoli based mainly on the higher fiber, but it’s not by a huge amount.
When it comes to vitamins, broccoli has more of vitamins B5, B6, B9, C, K, and choline, whereas asparagus has more of vitamins A, B1, B2, B3, and E. This would already be a 6:5 marginal win for broccoli, but it’s worth bearing in mind that broccoli’s margins are greater, especially with broccoli having around 15x the amount of vitamin C. So, a clear win for broccoli, respectable as asparagus may be.
In the category of minerals, broccoli has more calcium, magnesium, manganese, phosphorus, potassium, and selenium, while asparagus boasts more copper, iron, and zinc. A 6:3 win for broccoli here.
Both vegetables also contain generous amounts of antioxidant polyphenols and other beneficial phytochemicals, often a little different from each other, so that’s a case for enjoying both.
Still, if you’re going to pick just one, we recommend the broccoli!
