Hyyyyyyydromatic…
Hydrotherapy is a very broad term, and refers to any (external) use of water as part of a physical therapy. Today we’re going to look at some of the top ways this can be beneficial—maybe you’ll know them all already, but maybe there’s something you hadn’t thought about or done decently; let’s find out!
Notwithstanding the vague nature of the umbrella term, some brave researchers have done a lot of work to bring us lots of information about what works and what doesn’t, so we’ll be using this to guide us today. For example:
Scientific Evidence-Based Effects of Hydrotherapy on Various Systems of the Body
Swimming (and similar)
An obvious one, this can for most people be a very good full-body exercise, that’s exactly as strenuous (or not) as you want/need it to be.
It can be cardio, it can be resistance, it can be endurance, it can be high-intensity interval training, it can be mobility work, it can be just support for an aching body that gets to enjoy being in the closest to zero-gravity we can get without being in freefall or in space.

Depending on what’s available for you locally (pool with a shallow area, for example), it can also be a place to do some exercises normally performed on land, but with your weight being partially supported (and as a counterpoint, a little resistance added to movement), and no meaningful risk of falling.
Tip: check out your local facilities, to see if they offer water aerobics classes; because the water necessitates slow movement, this can look a lot like tai chi to watch, but it’s great for mobility and balance.
Water circuit therapy
This isn’t circuit training! Rather, it’s a mixture of thermo- and cryotherapy, that is to say, alternating warm and cold water immersion. This can also be interspersed with the use of a sauna, of course.

this last one is about thermal shock-mediated hormesis, which sounds drastic, but it’s what we’re doing here with the hot and cold, and it’s good for most people!
Pain relief
Most of the research for this has to do with childbirth pain rather than, for example, back pain, but the science is promising:
Post-exercise recovery
It can be tempting to sink into a hot bath, or at least enjoy a good hot shower, after strenuous exercise. But does it help recovery too? The answer is probably yes:

Mythbusting Moldy Food
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.
Most Food Should Not Be Fuzzy
In yesterday’s newsletter, we asked you for your policy when it comes to mold on food (aside from intentional mold, e.g. blue cheese etc), and the responses were interesting:
- About 49% said “throw the whole thing away no matter what it is; it is dangerous”
- About 24% said “cut the mold off and eat the rest of whatever it is”
- The remainder were divided equally between “eat it all; keep the immune system on its toes” and “cut the mold off bread, but moldy animal products are dangerous”
So what does the science say?
Some molds are safe to eat: True or False?
True! We don’t think this is contentious so we’ll not spend much time on it, but just for the sake of being methodical: foods that are supposed to have mold on, including many kinds of cheese and even some kinds of cured meat (salami is an example; that powdery coating is mold).
We could give a big list of safe and unsafe molds, but that would be a list of names and let’s face it, they don’t introduce themselves by name.
However! The litmus test of “is it safe to eat” is:
Did you acquire it with this mold already in place and exactly as expected and advertised?
- If so, it is safe to eat (unless you have an allergy or such)
- If not, it is almost certainly not safe to eat
(more on why, later)
The “sniff test” is a good way to tell if moldy food is bad: True or False?
False. Very false. Because of how the sense of smell works.
You may feel like smell is a way of knowing about something at a distance, but the only way you can smell something is if particles of it are physically connecting with your olfactory receptors inside you. Yes, that has unfortunate implications about bathroom smells, but for now, let’s keep our attention in the kitchen.
If you sniff a moldy item of food, you will now have its mold spores inside your respiratory system. You absolutely do not want them there.
If we cut off the mold, the rest is safe to eat: True or False?
True or False, depending on what it is:
- Hard vegetables (e.g carrots, cabbage), and hard cheeses (e.g. Gruyère, Gouda) – cut off with an inch margin, and it should be safe
- Soft vegetables (e.g. tomatoes, and any vegetables that were hard but are now soft after cooking) – discard entirely; it is unsafe
- Anything else – discard entirely; it is unsafe
The reason for this is because in the case of the hard products mentioned, the mycelium roots of the mold cannot penetrate far.
In the case of the soft products mentioned, the surface mold is “the tip of the iceberg”, and the mycelium roots, which you will not usually be able to see, will penetrate the rest of it.
“Anything else” seems like quite a sweeping statement, but fruits, soft cheeses, yogurt, liquids, jams and jellies, cooked grains and pasta, meats, and yes, bread, are all things where the roots can penetrate deeply and easily. Regardless of you only being able to see a small amount, the whole thing is probably moldy.
The USDA has a handy downloadable factsheet:
Molds On Food: Are They Dangerous?
Eating a little mold is good for the immune system: True or False?
False, generally. There are of course countless types of mold, but not only are many of them pathogenic (mycotoxins), but also, a food that has mold will usually also have pathogenic bacteria along with the mold.
See for example: Occurrence, Toxicity, and Analysis of Major Mycotoxins in Food
Food poisoning will never make you healthier.
But penicillin is safe to eat: True or False?
False, and also penicillin is not the mold on your bread (or other foods).
Penicillin, an antibiotic* molecule, is produced by some species of Penicillium sp., a mold. There are hundreds of known species of Penicillium sp., and most of them are toxic, usually in multiple ways. Take for example:
Penicillium roqueforti PR toxin gene cluster characterization
*it is also not healthy to consume antibiotics unless it is seriously necessary. Antibiotics will wipe out most of your gut’s “good bacteria”, leaving you vulnerable. People have died from C. diff infections for this reason. So obviously, if you really need to take antibiotics, take them as directed, but if not, don’t.
See also: Four Ways Antibiotics Can Kill You
One last thing…
It may be that someone reading this is thinking “I’ve eaten plenty of mold, and I’m fine”. Or perhaps someone you tell about this will say that.
But there are two reasons this logic is flawed:
- Survivorship bias (like people who smoke and live to 102; we just didn’t hear from the 99.9% of people who smoke and die early)
- Being unaware of illness is not being absent of illness. Anyone who’s had an alarming diagnosis of something that started a while ago will know this, of course. It’s also possible to be “low-level ill” often and get used to it as a baseline for health. It doesn’t mean it’s not harmful for you.
Stay safe!

How To Make Drinking Less Harmful
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.
Making Drinking Less Harmful
We often talk of the many ways alcohol harms our health, and we advocate for reducing (or eliminating) its consumption. However, it’s not necessarily as easy as all that, and it might not even be a goal that everyone has. So, if you’re going to imbibe, what can you do to mitigate the harmful effects of alcohol?
There is no magical solution
Sadly. If you drink alcohol, there will be some harmful effects, and nothing will completely undo that. But there are some things that can at least help—read on to learn more!
Coffee
It’s not the magical sober-upperer that some would like it to be, but it is good against the symptoms of alcohol intoxication, and slightly reduces the harm to your body, because it is:
- Hydrating (whereas alcohol is dehydrating)
- A source of antioxidants (whereas alcohol causes oxidative stress, which has nothing to do with psychological stress, and is a kind of cellular damage)
- A stimulant, assuming it is not decaffeinated (it’s worth noting that its stimulant effects work partly by triggering vasoconstriction, which is the opposite of the vasodilation caused by alcohol)
To this end, the best coffee for anti-alcohol effects should be:
- Caffeinated, and strong
- Long (we love espresso, but we need hydration here and that comes from volume!)
- Without sugar (you don’t want to create an adverse osmotic gradient to leech water from your body)
As for milk/cream/whatever, have it or don’t, per your usual preference. It won’t make any difference to the alcohol in your system.
Antioxidants, polyphenols, flavonoids, and things with similar mechanisms
We mentioned that coffee contains antioxidants, but if you want to really bring out the heavy guns, taking more powerful antioxidants can help a lot. If you don’t have the luxury of enjoying berries and cacao nibs by the handful, supplements that have some similar benefits are a perfectly respectable choice.
For example, you might want to consider green tea extract:
L-theanine 200mg (available on Amazon)
Specialist anti-alcohol drugs
These are somewhat new and the research is still ongoing, but for example:
Dihydromyricetin (DHM) as a novel anti-alcohol intoxication medication
In short, DHM is a flavonoid (protects against the oxidative stress caused by alcohol, and has been found to reduce liver damage—see the above link) and also works on GABA-receptors (reduces alcohol withdrawal symptoms after cessation of drinking, and thus also reduces hangovers).
Once again: the marketing claims of such drugs may be bold, but there’s a lot that’s not known and they’re not a magic pill. They do NOT mean you can take them alongside drinking and drink what you like with impunity. However, they may help mitigate some of the harmful effects of alcohol. If you wish to try them, these can be purchased at pharmacies or online, for example:
Alcohol Defense Capsules (available on Amazon)
Bottom line
Alcohol is bad for your health and none of the above will eliminate the health risks. But, if you’re going to have alcohol, then having the above things as well may at least somewhat reduce the harm done.

Pneumonia: Prevention Is Better Than Cure
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.
Pneumonia: What We Can & Can’t Do About It
Pneumonia is a significant killer of persons over the age of 65, with the risk increasing with age after that, rising very sharply around the age of 85:
While pneumonia is treatable, especially in young healthy adults, the risks get more severe in the older age brackets, and it’s often the case that someone goes into hospital with one thing, then develops pneumonia, which the person was already not in good physical shape to fight, because of whatever hospitalized them in the first place:
American Lung Association | Pneumonia Treatment and Recovery
Other risk factors besides age
There are a lot of things that can increase our risk factor for pneumonia; they mainly fall into the following categories:
- Autoimmune diseases
- Other diseases of the immune system (e.g. HIV)
- Medication-mediated immunosuppression (e.g. after an organ transplant)
- Chronic lung diseases (e.g. asthma, COPD, Long Covid, emphysema, etc)
- Other serious health conditions ← we know this one’s broad, but it encompasses such things as diabetes, heart disease, and cancer
See also:
Why Chronic Obstructive Pulmonary Disease (COPD) Is More Likely Than You Think
Things we can do about it
When it comes to risks, we can’t do much about our age and some of the other above factors, but there are other things we can do to reduce our risk, including:
- Get vaccinated against pneumonia if you are over 65 and/or have one of the aforementioned risk factors. This is not perfect (it only reduces the risk for certain kinds of infection) and may not be advisable for everyone (like most vaccines, it can put the body through its paces a bit after taking it), so speak with your own doctor about this, of course.
- See also: Vaccine Mythbusting
- Avoid contagion. While pneumonia itself is not spread person-to-person, it is caused by bacteria or viruses (there are numerous kinds) that are opportunistic and often become a secondary infection when the immune system is already busy with the first one. So, if possible avoid being in confined spaces with many people, and do wash your hands regularly (as a lot of germs are transferred that way and can get into the respiratory tract because you touched your face or such).
- See also: The Truth About Handwashing
- If you have a cold, or flu, or other respiratory infection, take it seriously, rest well, drink fluids, get good immune-boosting nutrients. There’s no such thing as “just a cold”; not anymore.
- Look after your general health too—health doesn’t exist in a vacuum, and nor does disease. Every part of us affects every other part of us, so anything that can be in good order, you want to be in good order.
This last one, by the way? It’s an important reminder that while some diseases (such as some of the respiratory infections that can precede pneumonia) are seasonal, good health isn’t.
We need to take care of our health as best we can every day along the way, because we never know when something could change.

Atomic Habits – by James Clear
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.
James Clear’s Atomic Habits has become “the” go-to book about the power of habit-forming. And, there’s no shortage of competition out there, so that’s quite a statement. What makes this book stand out?
A lot of books start by assuming you want to build habits. That can seem a fair assumption; after all, we picked up the book! But an introductory chapter really hammers home the idea in a way that makes it a lot more motivational:
- Habits are the compound interest of productivity
- This means that progress is not linear, but exponential
- Habits can also be stacked, and thus become synergistic
- The more positive habits you add incrementally, the easier they become because each thing is making your life easier/better
For example:
- It’s easier to save money if you’re in good health
- It’s easier to sleep better if you do not have financial worries
- It’s easier to build your relationship with your loved ones if you’re not tired
…and so on.
For many people this presents a Catch-22 problem! Clear instead presents it as an opportunity… Start wherever you like, but just start small, with some two-minute thing, and build from there.
A lot of the book is given over to:
- how to form effective habits (using his “Four Laws”)
- how to build them into your life
- how to handle mishaps
- how to make sure your habits are working for you
- how to see habits as part of your identity, and not just a goal to be checked off
The last one is perhaps key—goals cease to be motivating once accomplished. Habits, on the other hand, keep spiralling upwards (if you guide them appropriately).
There’s lots more we could say, but it’s a one-minute book review, so we’ll just close by saying:
This book can help you to become the kind of person who genuinely gets a little better each day, and reaps the benefits over time.

How to be kind to yourself (without going to a day spa)
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.
“I have to be hard on myself,” Sarah told me in a recent telehealth psychology session. “I would never reach my potential if I was kind and let myself off the hook.”
I could empathise with this fear of self-compassion from clients such as Sarah (not her real name). From a young age, we are taught to be kind to others, but self-kindness is never mentioned.
Instead, we are taught success hinges on self-sacrifice. And we need a healthy inner critic to bully us forward into becoming increasingly better versions of ourselves.
But research shows there doesn’t have to be a trade-off between self-compassion and success.
Self-compassion can help you reach your potential, while supporting you to face the inevitable stumbles and setbacks along the way.
What is self-compassion?
Self-compassion has three key ingredients.
1. Self-kindness
This involves treating yourself with the same kindness you would extend towards a good friend – via your thoughts, feelings and actions – especially during life’s difficult moments.
For instance, if you find yourself fixating on a minor mistake you made at work, self-kindness might involve taking a ten-minute walk to shift focus, and reminding yourself it is OK to make mistakes sometimes, before moving on with your day.
2. Mindfulness
In this context, mindfulness involves being aware of your own experience of stress or suffering, rather than repressing or avoiding your feelings, or over-identifying with them.
Basically, you must see your stress with a clear (mindful) perspective before you can respond with kindness. If we avoid or are consumed by our suffering, we lose perspective.
3. Common humanity
Common humanity involves recognising our own experience of suffering as something that unites us as being human.
For instance, a sleep-deprived parent waking up (for the fourth time) to feed their newborn might choose to think about all the other parents around the world doing exactly the same thing – as opposed to feeling isolated and alone.
It’s not about day spas, or booking a manicure
When Sarah voiced her fear that self-compassion would prevent her success, I explained self-compassion is distinct from self-indulgence.
“So is self-compassion just about booking in more mani/pedis?” Sarah asked.
Not really, I explained. A one-off trip to a day spa is unlikely to transform your mental health.
Instead, self-compassion is a flexible psychological resilience factor that shapes our thoughts, feelings and actions.
It’s associated with a suite of benefits to our wellbeing, relationships and health.
What does the science say?
Over the past 20 years, we’ve learned self-compassionate people enjoy a wide range of benefits. They tend to be happier and have fewer psychological symptoms of distress.
Those high on self-compassion persevere following a failure. They say they are more motivated to overcome a personal weakness than those low on self-compassion, who are more likely to give up.
So rather than feeling trapped by your inadequacies, self-compassion encourages a growth mindset, helping you reach your potential.
However, self-compassion is not a panacea. It will not change your life circumstances or somehow make life “easy”. It is based on the premise that life is hard, and provides practical tools to cope.
It’s a factor in healthy ageing
I research menopause and healthy ageing and am especially interested in the value of self-compassion through menopause and in the second half of life.
Because self-compassion becomes important during life’s challenges, it can help people navigate physical symptoms (for instance, menopausal hot flushes), life transitions such as divorce, and promote healthy ageing.
I’ve also teamed up with researchers at Autism Spectrum Australia to explore self-compassion in autistic adults.
We found autistic adults report significantly lower levels of self-compassion than neurotypical adults. So we developed an online self-compassion training program for this at-risk population.
Three tips for self-compassion
You can learn self-compassion with these three exercises.
1. What would you say to a friend?
Think back to the last time you made a mistake. What did you say to yourself?
If you notice you’re treating yourself more like an enemy than a friend, don’t beat yourself up about it. Instead, try to think about what you might tell a friend, and direct that same friendly language towards yourself.
2. Harness the power of touch
Soothing human touch activates the parasympathetic “relaxation” branch of our nervous system and counteracts the fight or flight response.
Specifically, self-soothing touch (for instance, by placing both hands on your heart, stroking your forearm or giving yourself a hug) reduces cortisol responses to psychosocial stress.
3. What do I need right now?
Sometimes, it can be hard to figure out exactly what self-compassion looks like in a given moment. The question “what do I need right now” helps clarify your true needs.
For example, when I was 37 weeks pregnant, I woke up bolt awake one morning at 3am.
Rather than beating myself up about it, or fretting about not getting enough sleep, I gently placed my hands on my heart and took a few deep breaths. By asking myself “what do I need right now?” it became clear that listening to a gentle podcast/meditation fitted the bill (even though I wanted to addictively scroll my phone).

8 Signs Of High Cortisol & How To Reverse “Cortisol Face”
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. Shereene Idriss has insights about the facial features that might indicate chronically elevated cortisol levels, and what to do about same:
At face value
Dr. Idriss notes that for most people, this should not be cause for undue concern, although hypercortisolism can also be associated with genetic disorders such as Cushing’s syndrome, as well as prolonged use of certain medication, or the presence of certain tumors. As well as facial swelling, hypercortisolism can also result in other physical changes like acne, weight gain, skin thinning, stretch marks, infections, and hair loss.
As for what to do about it, she recommends addressing lifestyle factors like poor sleep, unhealthy diet, alcohol consumption, and lack of hydration to reduce facial puffiness related to stress. Diet suggestions include incorporating foods rich in magnesium, vitamin C, and omega-3s, such as leafy greens, fatty fish, nuts and seeds, and berries.
She also suggests some supplements to consider, such as ashwagandha, magnesium, omega-3s, and/or l-theanine, but you might want to speak to your doctor/pharmacist to check in case of contraindications per any other conditions you may have, or medications you may be on.
