We’ve written about sleep books before, so what makes this one different? Its major selling point is: most of the focus isn’t on the things that everyone already knows.
Yes, there’s a section on sleep hygiene and yes it’ll tell you to cut the caffeine and alcohol, but most of the advice here is beyond that.
Rather, it looks at finding out (if you don’t already know for sure) what is keeping you from healthy sleep, be it environmental, directly physical, or psychological, and breaking out of the stress-sleep cycle that often emerges from such.
The style is light and conversational, but includes plenty of science too; Dr. Porter knows her stuff.
Bottom line: if you feel like you know what you should be doing, but somehow life keeps conspiring to stop you from doing it, then this is the book that could help you break out that cycle.

Is It Dementia?
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.
Spot The Signs (Because None Of Us Are Immune)
Dementia affects increasingly many people, and unlike a lot of diseases, it disproportionately affects people in wealthy industrialized nations.
There are two main reasons for this:
- Longevity (in poorer countries, more people die of other things sooner; can’t get age-related cognitive decline if you don’t age)
- Lifestyle (in the age of convenience, it has never been easier to live an unhealthy lifestyle)
The former is obviously no bad thing for those of us lucky enough to be in wealthier countries (though even in such places, good healthcare access is of course sadly not a given for all).
The latter, however, is less systemic and more epidemic. But it does cut both ways:
- An unhealthy lifestyle is much easier here, yes
- A healthier lifestyle is much easier here, too!
This then comes down to two factors in turn:
- Information: knowing about dementia, what things lead to it, what to look out for, what to do
- Motivation: priorities, and how much attention we choose to give this matter
So, let’s get some information, and then give it our attention!
More than just memory
It’s easy to focus on memory loss, but the four key disabilities directly caused by dementia (each person may not get all four), can be remembered by the mnemonic: “AAAA!”
No, somebody didn’t just murder your writer. It’s:
- Amnesia: memory loss, in one or more of its many forms
- e.g. short term memory loss, and/or inability to make new memories
- Aphasia: loss of ability to express oneself, and/or understand what is expressed
- e.g. “More people have been to Berlin than I have”
- Or even less communication-friendly, Broca’s (Expressive) Aphasia and Wernicke’s (Receptive) Aphasia
- Apraxia: loss of ability to do things, through no obvious physical disability
- e.g. staring at the bathroom mirror wondering how to brush one’s teeth
- Agnosia: loss of ability to recognize things
- e.g. prosopagnosia, also called face-blindness.
If any of those seem worryingly familiar, be aware that while yes, it could be a red flag, what’s most important is patterns of these things.
Another difference between having a momentary brainlapse and having dementia might be, for example, the difference between forgetting your keys, and forgetting what keys do or how to use one.
That said, some are neurological deficits that may show up quite unrelated to dementia, including most of those given as examples above. So if you have just one, then that’s probably worthy of note, but probably not dementia.
Writer’s anecdote: I have had prosopagnosia all my life. To give an example of what that is like and how it’s rather more than just “bad with faces”…
Recently I saw my neighbor, and I could tell something was wrong with her face, but I couldn’t put my finger on what it was. Then some moments later, I realized I had mistaken her hat for her face. It was a large beanie with a panda design on it, and that was facelike enough for me to find myself looking at the wrong face.
Subjective memory matters as much as objective
Objective memory tests are great indicators of potential cognitive decline (or improvement!), but even a subjective idea of having memory problems, that one’s memory is “not as good as it used to be”, can be an important indicator too:
Subjective memory may be marker for cognitive decline
And more recently:
If your memory feels like it’s not what it once was, it could point to a future dementia risk
If you’d like an objective test of memory and other cognitive impairments, here’s the industry’s gold standard test (it’s free):
SAGE: A Test to Detect Signs of Alzheimer’s and Dementia
(The Self-Administered Gerocognitive Exam (SAGE) is designed to detect early signs of cognitive, memory or thinking impairments)
There are things that can look like dementia that aren’t
A person with dementia may be unable to recognize their partner, but hey, this writer knows that feeling very well too. So what sets things apart?
More than we have room for today, but here’s a good overview:
What are the early signs of dementia, and how does it differ from normal aging?

Is still water better for you than sparkling water?
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.
Still or sparkling? It’s a question you’ll commonly hear in a café or restaurant and you probably have a preference. But is there any difference for your health?
If you love the fizz, here’s why you don’t have to pass on the sparkling water.
Brent Hofacker/Shutterstock What makes my water sparkle?
This article specifically focuses on comparing still filtered water to carbonated filtered water (called “sparkling water” or “unflavoured seltzer”). Soda water, mineral water, tonic water and flavoured water are similar, but not the same product.
The bubbles in sparkling water are created by adding carbon dioxide to filtered water. It reacts to produce carbonic acid, which makes sparkling water more acidic (a pH of about 3.5) than still (closer to neutral, with a pH around 6.5-8.5).
Which drink is healthiest?
Water is the best way to hydrate our bodies. Research shows when it comes to hydration, still and sparkling water are equally effective.
Some people believe water is healthier when it comes from a sealed bottle. But in Australia, tap water is monitored very carefully. Unlike bottled water, it also has the added benefit of fluoride, which can help protect young children against tooth decay and cavities.
Sparkling or still water is always better than artificially sweetened flavoured drinks or juices.
Isn’t soda water bad for my teeth and bones?
There’s no evidence sparkling water damages your bones. While drinking a lot of soft drinks is linked to increased fractures, this is largely due to their association with higher rates of obesity.
Sparkling water is more acidic than still water, and acidity can soften the teeth’s enamel. Usually this is not something to be too worried about, unless it is mixed with sugar or citrus, which has much higher levels of acidity and can harm teeth.
However, if you grind your teeth often, the softening could enhance the damage it causes. If you’re undertaking a home whitening process, sparkling water might discolour your teeth.
In most other cases, it would take a lot of sparkling water to pass by the teeth, for a long period of time, to cause any noticeable damage.
How does drinking water affect digestion?
There is a misconception drinking water (of any kind) with a meal is bad for digestion.
While theoretically water could dilute stomach acid (which breaks down food), the practice of drinking it doesn’t appear to have any negative effect. Your digestive system simply adapts to the consistency of the meal.
Some people do find that carbonated beverages cause some stomach upset. This is due to the build-up of gases, which can cause bloating, cramping and discomfort. For people with an overactive bladder, the acidity might also aggravate the urinary system.
Interestingly, the fizzy “buzz” you feel in your mouth from sparkling water fades the more you drink it.
Is cold water harder to digest?
You’ve chosen still or sparkling water. What about its temperature?
There are surprisingly few studies about the effect of drinking cold water compared to room temperature. There is some evidence colder water (at two degrees Celsius) might inhibit gastric contractions and slow down digestion. Ice water may constrict blood vessels and cause cramping.
However other research suggests drinking cold water might temporarily boost metabolism, as the body needs to expend energy to warm it up to body temperature. This effect is minimal and unlikely to lead to significant weight loss.
Which water wins?
The bottom line is water is essential, hydrates us and has countless other health benefits. Water, with carbonated bubbles or without, will always be the healthiest drink to choose.
And if you’re concerned about any impact to teeth enamel, one trick is to follow sparkling water with a glass of still. This helps rinse the teeth and return your mouth’s acidity back to normal.

5 Golden Rules To Lose Belly Fat
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 belly is often the first place we gain fat and the last to lose it—due to hormonal changes, poor blood flow, and fat cell types. This also means that weight loss efforts can result in it looking worse before it looks better, as we lose weight from elsewhere around it. But, there is a way forwards:
What to do about it
Cori Lefkowith, of “Redefining Strength” and “Strength At Any Age” fame, advise that we follow the following “5 golden rules”:
- Mindset: avoid “All or Nothing” thinking; focus on small, sustainable changes and consistent habits.
- Macros: prioritize protein (40%+ of calories), balance fats and carbs for hormonal health, and avoid extreme calorie deficits (your body will try to save you from starvation by slowing your metabolism to conserve energy, and storing fat).
- Nutrition quality: focus on whole, nutrient-dense foods for better satiety, gut health, and energy. Get plenty of fiber and water; your body still needs those too.
- Muscle building: strength training preserves muscle, boosts metabolism, and improves body composition—don’t ditch your strength training for cardio; it won’t help and that swap would hinder..
- Daily walks: 15–20 minutes of walking after dinner aids digestion, and reduces stress (remember: stress invites your body to store extra fat, especially at the belly). It also incidentally burns calories without stressing the body, but honestly, it’s really not very many calories, so that’s not the main reason to do it.

Do Probiotics Work For Weight Loss?
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.
It’s Q&A Day at 10almonds!
Have a question or a request? We love to hear from you!
In cases where we’ve already covered something, we might link to what we wrote before, but will always be happy to revisit any of our topics again in the future too—there’s always more to say!
As ever: if the question/request can be answered briefly, we’ll do it here in our Q&A Thursday edition. If not, we’ll make a main feature of it shortly afterwards!
So, no question/request too big or small
❝Can you talk about using probiotics for weight loss? Thanks❞
Great question! First, a quick catch-up:
How Much Difference Do Probiotic Supplements Make, Really?
Our above-linked article covers a number of important benefits of probiotic supplements, but we didn’t talk about weight loss at all. So let’s examine whether probiotics are useful for weight loss.
Up-front summary: the science is unclear
This 2021 systematic review found that they are indeed very effective:
❝The intake of probiotics or synbiotics could lead to significant weight reductions, either maintaining habitual lifestyle habits or in combination with energy restriction and/or increased physical activity for an average of 12 weeks.
Specific strains belonging to the genus Lactobacillus and Bifidobacterium were the most used and those that showed the best results in reducing body weight.
Both probiotics and synbiotics have the potential to help in weight loss in overweight and obese populations.❞
This slightly older (2015) systematic review and meta-analysis found the opposite:
❝Collectively, the RCTs examined in this meta-analysis indicated that probiotics have limited efficacy in terms of decreasing body weight and BMI and were not effective for weight loss.❞
Source: Probiotics for weight loss: a systematic review and meta-analysis
And in case that’s not balanced enough, this 2020 randomized controlled trial got mixed results:
❝Regression analysis performed to correlate abundance of species following supplementation with body composition parameters and biomarkers of obesity found an association between a decrease over time in blood glucose and an increase in Lactobacillus abundance, particularly in the synbiotic group.
However, the decrease over time in body mass, BMI, waist circumstance, and body fat mass was associated with a decrease in Bifidobacterium abundance.❞
Source: Effects of Synbiotic Supplement on Human Gut Microbiota, Body Composition and Weight Loss in Obesity
Summary
Probiotics may or may not work for weight loss.
In all likelihood, it depends on the blend of cultures contained in the supplement. It’s possible that Lactobacillus is more beneficial for weight loss than Bifidobacterium, which latter may actually reduce weight loss.
Or it might not, because that was just one study and correlation ≠ causation!
We’d love to give you a hard-and-fast answer, but if the data doesn’t support a hard-and-fast answer, we’re not going to lie to you.
What we can say for sure though is that probiotics come with very many health benefits, so whether or not weight loss is one of them, they’re a good thing to have for most people.
Some further articles that may interest you:

- Making Friends With Your Gut (You Can Thank Us Later) ← gut health 101
- Burn! How To Boost Your Metabolism ← these things can help change your metabolic base rate, which is highly relevant to weight loss
- How To Do HIIT (Without Wrecking Your Body) ←unlike most forms of exercise, which cause the body to slow the metabolism afterwards to compensate, high-intensity interval training results in an increased metabolic rate (so generally: fat-burning) for several hours after training.

The Cold Truth About Respiratory Infections
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 Pathogens That Came In From The Cold
Yesterday, we asked you about your climate-themed policy for avoiding respiratory infections, and got the above-depicted, below-described, set of answers:
- About 46% of respondents said “Temperature has no bearing on infection risk”
- About 31% of respondents said “It’s important to get plenty of cold, fresh air, as this kills/inactivates pathogens”
- About 22% of respondents said “It’s important to stay warm to avoid getting colds, flu, etc”
Some gave rationales, including…
For “stay warm”:
❝Childhood lessons❞
For “get cold, fresh air”:
❝I just feel that it’s healthy to get fresh air daily. Whether it kills germs, I don’t know❞
For “temperature has no bearing”:
❝If climate issue affected respiratory infections, would people in the tropics suffer more than those in colder climates? Pollutants may affect respiratory infections, but I doubt just temperature would do so.❞
So, what does the science say?
It’s important to stay warm to avoid getting colds, flu, etc: True or False?
False, simply. Cold weather does increase the infection risk, but for reasons that a hat and scarf won’t protect you from. More on this later, but for now, let’s lay to rest the idea that bodily chilling will promote infection by cold, flu, etc.
In a small-ish but statistically significant study (n=180), it was found that…
❝There was no evidence that chilling caused any acute change in symptom scores❞
Read more: Acute cooling of the feet and the onset of common cold symptoms
Note: they do mention in their conclusion that chilling the feet “causes the onset of cold symptoms in about 10% of subjects who are chilled”, but the data does not support that conclusion, and the only clear indicator is that people who are more prone to colds generally, were more prone to getting a cold after a cold water footbath.
In other words, people who were more prone to colds remained more prone to colds, just the same.
It’s important to get plenty of cold, fresh air, as this kills/inactivates pathogens: True or False?
Broadly False, though most pathogens do have an optimal operating temperature that (for obvious reasons) is around normal human body temperature.
However, given that they don’t generally have to survive outside of a host body for long to get passed on, the fact that the pathogens may be a little sluggish in the great outdoors will not change the fact that they will be delighted by the climate in your respiratory tract as soon as you get back into the warm.
With regard to the cold air not being a reliable killer/inactivator of pathogens, we call to the witness stand…
Polar Bear Dies From Bird Flu As H5N1 Spreads Across Globe
(it was found near Utqiagvik, one of the northernmost communities in Alaska)
Because pathogens like human body temperature, raising the body temperature is a way to kill/inactivate them: True or False?
True! Unfortunately, it’s also a way to kill us. Because we, too, cannot survive for long above our normal body temperature.
So, for example, bundling up warmly and cranking up the heating won’t necessarily help, because:
- if the temperature is comfortable for you, it’s comfortable for the pathogen
- if the temperature is dangerous to the pathogen, it’s dangerous to you too
This is why the fever response evolved, and/but why many people with fevers die anyway. It’s the body’s way of playing chicken with the pathogen, challenging “guess which of us can survive this for longer!”
Temperature has no bearing on infection risk: True or False?
True and/or False, circumstantially. This one’s a little complex, but let’s break it down to the essentials.
- Temperature has no direct effect, for the reasons we outlined above
- Temperature is often related to humidity, which does have an effect
- Temperature does tend to influence human behavior (more time spent in open spaces with good ventilation vs more time spent in closed quarters with poor ventilation and/or recycled air), which has an obvious effect on transmission rates
The first one we covered, and the third one is self-evident, so let’s look at the second one:
Temperature is often related to humidity, which does have an effect
When the environmental temperature is warmer, water droplets in the air will tend to be bigger, and thus drop to the ground much more quickly.
When the environmental temperature is colder, water droplets in the air will tend to be smaller, and thus stay in the air for longer (along with any pathogens those water droplets may be carrying).
Some papers on the impact of this:
- Cold temperature and low humidity are associated with increased occurrence of respiratory tract infections
- A Decrease in Temperature and Humidity Precedes Human Rhinovirus Infections in a Cold Climate
So whatever temperature you like to keep your environment, humidity is a protective factor against respiratory infections, and dry air is a risk factor.
So, for example:
- If the weather doesn’t suit having good ventilation, a humidifier is a good option
- Being in an airplane is one of the worst places to be for this, outside of a hospital
Don’t have a humidifier? Here’s an example product on Amazon, but by all means shop around.
A crock pot with hot water in and the lid off is also a very workable workaround too

Retrain Your Brain – by Dr. Seth Gillihan
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.
15-Minute Arabic”, “Sharpen Your Chess Tactics in 24 Hours”, “Change Your Life in 7 Days”, “Cognitive Behavioral Therapy in 7 weeks”—all real books from this reviewer’s shelves.
The thing with books with these sorts of time periods in the titles is that the time period in the title often bears little relation to how long it takes to get through the book. So what’s the case here?
You’ll probably get through it in more like 7 days, but the pacing is more important than the pace. By that we mean:
Dr. Gillihan starts by assuming the reader is at best “in a rut”, and needs to first pick a direction to head in (the first “week”) and then start getting one’s life on track (the second “week”).
He then gives us, one by one, an array of tools and power-ups to do increasingly better. These tools aren’t just CBT, though of course that features prominently. There’s also mindfulness exercises, and holistic / somatic therapy too, for a real “bringing it all together” feel.
And that’s where this book excels—at no point is the reader left adrift with potential stumbling-blocks left unexamined. It’s a “whole course”.
Bottom line: whether it takes you 7 hours or 7 months, “Cognitive Behavioral Therapy in 7 Weeks” is a CBT-and-more course for people who like courses to work through. It’ll get you where you’re going… Wherever you want that to be for you!
