  • How To Mobilize Your Hips (Without Kneeling)

    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.

    Hip and knee mobility are both very important, but how to improve one if the other is poor? Mobility coach Alisa Szyman shows us how:

    Let’s get hip

    Step by step:

    1. Warm-up: lie on your back with one knee bent and gently pulled toward your chest. Draw small controlled circles with your knee in both directions, keeping your pelvis steady and core lightly engaged. Switch legs and repeat. Then, with both knees bent and feet flat, let both knees drop gently side to side to loosen hip rotation and lower back stiffness.
    2. Clamshell and internal rotation: lie on your side supported by your forearm or elbow, knees slightly bent, feet stacked. Lift your top knee (clamshell), then bring your knees together and lift your top foot, rotating from your hip. This strengthens your glute medius and improves internal and external hip rotation.
    3. Hip abduction: from the same position, extend your top leg straight and lift it upward, keeping your body still and core strong. Switch sides and repeat both the clamshell and hip abduction sequence.
    4. Lying leg openers: lie on your back with both legs extended toward the ceiling. Open your legs out to the sides, then squeeze them back together like horizontal scissors. Keep your lower back anchored and core stable to work your inner thighs and core.
    5. Side-lying hip circles: on your side, bend your bottom leg for stability and keep your top leg straight. Draw small or large circles with your top leg, controlling the motion through your hip. This improves joint mobility and glute activation.
    6. Inner thigh lift: from the same position, bend your top leg and place the foot in front of you on the floor. Extend your bottom leg straight and lift it slightly off the floor to strengthen your inner thigh and groin. Switch sides and repeat both the circles and adduction exercise.
    7. Band stretch: lie on your back with one leg extended up, then gently guide it across your body while keeping your shoulders grounded. Feel the stretch along the outside of your hip and thigh. Adjust the height for comfort.
    8. Figure-four stretch and twist: lie on your back, bend your knees, and cross your left ankle over your right knee. Stay here for a static stretch or drop both legs to the side for a gentle twist, holding or moving dynamically. Switch sides.
    9. Pancake stretch: sit with your legs wide apart and hinge forwards from your hips, reaching your arms ahead while keeping your spine long. Use a cushion or yoga block under your hips if needed. This deep stretch opens your hips, lengthens your hamstrings, and promotes good spinal alignment.

    You don’t have to do them all, of course, but it’s at the very least a good menu to choose from, and doing some is infinitely better than doing none!

  • Pine Nuts vs Pecans – 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 pine nuts to pecans, we picked the pine nuts.

    Why?

    Both have their merits!

    In terms of macros, pine nuts have more protein while pecans have more fiber. They’re about equal on fats, although pine nuts have more polyunsaturated fat and pecans have more monounsaturated fat, of which, both are healthy. They’re also about equal on carbs. So really it comes down to the subjective choice between prioritizing protein and prioritizing fiber. On principle, we pick fiber, which gives the win to pecans, but your preference in this regard may differ; prioritizing the protein would give the win to pine nuts.

    In the category of vitamins, pine nuts have more of vitamins B2, B3, B9, E, K, and choline, while pecans have more of vitamins A, B1, B5, B6, and C. Thus, a 6:5 marginal win for pine nuts.

    Looking at the minerals, pine nuts have more copper, iron, magnesium, manganese, phosphorus, potassium, and zinc, while pecans have more calcium and selenium. An easy win for pine nuts this time.

    Adding up the sections makes for a win for pine nuts, but of course, enjoy either or (preferably) both; diversity is good!

  • How does the hair-loss drug finasteride work? Can it affect my mental health?

    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.

    For many men the gradual thinning of hair is about more than just their appearance. Finasteride, a drug widely prescribed for the treatment of male pattern baldness has been used effectively for many years for this deeply personal problem.

    Yet, behind its use are growing concerns about its link to the development of depression, anxiety, and even suicidal thoughts.

    There is now critical discussion among both users and health-care professionals about the potential hazards associated with its continued use.

    So how does the drug work? And what does the evidence say about the risk of developing a mental health problem?

    agrobacter/Getty

    How does finasteride work?

    Finasteride is used to treat androgenetic alopecia, also known as male pattern baldness. It works to regrow hair and prevent the further loss of hair.

    One of the key causes of pattern baldness is the production of a hormone called dihydrotestosterone which the body makes from testosterone. When it binds to the follicles of hairs, it initiates a process called hair follicle miniaturisation. This is where the growth cycle of the hair becomes progressively shorter, resulting in thinner and weaker hair.

    Finasteride works by blocking the enzyme that converts testosterone to dihydrotestosterone. By blocking the enzyme, dihydrotestosterone concentrations can be reduced by around 60–70% for the majority of men.

    Finasteride was first approved in the late 1990s as a prescription-only medicine and is taken as a daily 1 milligram oral tablet. Medications available at a higher 5 mg daily dose are not used for baldness, but as a treatment for non-cancerous prostate enlargement.

    This medication is not indicated for women, even though they can also have this type of hair loss.

    How can it impact your mental health?

    Changes in mental health are not listed as an established side effect in Australian guidance given to health-care professionals.

    Based on clinical trials, the most common effects include:

    • decreased libido
    • erectile dysfunction
    • reduced semen production.

    The guidance also describes an increased risk of prostate cancer and a potential risk for breast cancer. Yes, men can get breast cancer too.

    While initial clinical trials conducted to obtain approval for the drug didn’t demonstrate mental health concerns, monitoring of patients using the drug has since indicated a potential increased risk of depression and suicidal thoughts. But as this is based on patients self-reporting symptoms, according to the guidance there is no definitive link.

    However, in May 2025, the European Medicines Agency safety committee stated suicidal thoughts was a confirmed side effect of finasteride. The European Union also advises patients that finasteride can cause a depressed mood and depression.

    Similarly, in a warning about compounded finasteride, the United States Food and Drug Administration stated in April 2025 that topical formulations of the drug has similar side effects to the oral version. These include depression, anxiety and suicidal thoughts.

    What should you do if it is affecting your mental health?

    If you notice changes in your mental health while taking the drug, try not to handle significant mood changes by yourself. If you’re feeling unusually low, anxious or emotionally unstable, check in with a doctor so they can help you figure out whether finasteride is contributing to your mood and what support you may need.

    If the symptoms are mild, they may suggest pausing finasteride to see whether things improve, or continuing with additional mental health support. If your symptoms are more severe, stopping the medication and getting prompt medical review may be appropriate.

    If you are taking finasteride and are worried about its side effects, it is safe to stop immediately. Most side effects ease once the medication is out of your system, although a small number of people have reported symptoms that persist.

    If you do decide to stop, this will mean that your hormone levels will gradually return to baseline and the hair growth seen with the drug will be lost over time.

    If finasteride is not the right fit for you, there is another evidence-based alternative.

    Topical minoxidil is a first-line treatment that can be used on its own or with other treatments and is available from pharmacies over the counter. It only works while it’s being used and may irritate the scalp, but its effectiveness is well-established and widely recommended.

    While depression and anxiety are associated with minoxidil, the incidence is much lower because of their topical application.

    There is also a medication called dutasteride. However, as it works in a similar way to finasteride, it may also increase your risk of developing mental health problems. So it is best to avoid dutasteride if finasteride is not suitable for you.

  • Cold Medicines & Heart Health

    Cold Medicines & Heart Health

    In the wake of many decongestants disappearing from a lot of shelves after a common active ingredient being declared useless*, you may find yourself considering alternative decongestants at this time of year.

    *In case you missed it:

    Why Is Oral Phenylephrine on the Market After Compelling Evidence of Its Ineffectiveness as a Decongestant?

    It doesn’t seem to be dangerous, by the way, just also not effective:

    FDA Panel Says Common OTC Decongestant, Phenylephrine, Is Useless

    Good for your nose, bad for your heart?

    With products based on phenylephrine out of the running, products based on pseudoephedrine, a competing drug, are enjoying a surge in popularity.

    Good news: pseudoephedrine works!

    Bad news: pseudoephedrine works because it is a vasoconstrictor, and that vasoconstriction reduces nasal swelling. That same vasoconstriction also raises overall blood pressure, potentially dangerously, depending on an assortment of other conditions you might have.

    Further reading: Can decongestants spike your blood pressure? What to know about hypertension and cold medicine

    Who’s at risk?

    The warning label, unread by many, reads:

    ❝Do not use this product if you have heart disease, high blood pressure, thyroid disease, diabetes, or difficulty in urination due to enlargement of the prostate gland, unless directed by a doctor❞

    Source: Harvard Health | Don’t let decongestants squeeze your heart

    What are the other options?

    The same source as above recommends antihistamines as an option to be considered, citing:

    ❝Antihistamines such as […] cetirizine (Zyrtec) and loratadine (Claritin) can help with a stuffy nose and are safe for the heart.❞

    But we’d be remiss not to mention drug-free options too, for example:

    • Saline rinse with a neti pot or similar
    • Use of a humidifier in your house/room
    • Steam inhalation, with or without eucalyptus etc

  • Chemically Imbalanced – by Dr. Joanna Moncrieff

    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 author, a professor of psychiatry, challenges the prevailing consensus that depression is often caused by a neurotransmitter imbalance, and as such, she further challenges the most popularly-prescribed class of antidepressants, SSRIs (selective serotonin reuptake inhibitors, whose job is do what it says on the tin, with the end goal of your brain having more serotonin in it because you’re keeping the serotonin you do make for longer).

    Her position is that depression is only caused by—and can only be fixed by—external factors, and that any benefit from antidepressants is placebo (in contrast, at 10almonds we wrote a while back about the more widely-accepted explanation of the hit-and-miss nature of whether antidepressants help someone is that often people are simply taking the wrong class of antidepressants for their specific depression; see: Antidepressants: Personalization Is Key!).

    She asserts that depression is not even a real medical condition, and is simply a social phenomenon, and she hopes that one day her colleagues in the profession will agree.

    It’s worth noting that a more moderate version of the first part of her assertions (that personal life conditions are often a major causal factor) is a common view by prescribers in the author’s native UK, where doctors have coined a colorful name for this condition. However, SSRIs are usually still the first recourse, on a “try it and see” basis.

    Dr. Moncrieff devotes several chapters to the unwanted side effects that can be experienced, and considers the incidence of such to be important enough—and persistent enough, sometimes lasting for a while after discontinuation—to be a violation of the “first, do no harm” principle.

    The style is… confident, let’s say. The author accepts that there are a plurality of views—hers, and the wrong ones held by most people in her profession. She also encourages us as readers to make our own decisions—avoid antidepressants (and, in fact, psychiatric meds of any kind, especially antipsychotics for people experiencing psychosis), or destroy our health; it’s up to us. She recognizes that very many people believe antidepressants have changed their lives for the better—and she considers those now-happier people to be fools duped by Big Pharma.

    Bottom line: on the one hand, this looks a lot like 288 pages of the author’s firmly-held confirmation bias; on the other hand, that doesn’t change the fact that it is worth at the very least considering, before embarking on a course of treatment, “why are we assuming that the issue is serotonin specifically?”, because (per the prevailing scientific consensus) sometimes it is, sometimes it isn’t.

  • The Truth About Vaccines

    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 Truth About Vaccines

    Yesterday we asked your views on vaccines, and we got an interesting spread of answers. Of those who responded to the poll, most were in favour of vaccines. We got quite a lot of comments this time too; we can’t feature them all, but we’ll include extracts from a few in our article today, as they raised interesting points!

    Vaccines contain dangerous ingredients that will harm us more than the disease would: True or False?

    False, contextually.

    Many people are very understandably wary of things they know full well to be toxic, being injected into them.

    One subscriber who voted for “Vaccines are poison, and/or are some manner of conspiracy ” wrote:

    ❝I think vaccines from 50–60 years ago are true vaccines and were safer than vaccines today. I have not had a vaccine for many, many years, and I never plan to have any kind of vaccine/shot again.❞

    They didn’t say why they personally felt this way, but the notion that “things were simpler back in the day” is a common (and often correct!) observation regards health, especially when it comes to unwanted additives and ultraprocessing of food.

    Things like aluminum or mercury in vaccines are much like sodium and chlorine in table salt. Sodium and chlorine are indeed both toxic to us. But in the form of sodium chloride, it’s a normal part of our diet, provided we don’t overdo it.

    Additionally, the amount of unwanted metals (e.g. aluminum, mercury) in vaccines is orders of magnitude smaller than the amount in dietary sources—even if you’re a baby and your “dietary sources” are breast milk and/or formula milk.

    In the case of formaldehyde (an inactivating agent), it’s also the dose that makes the poison (and the quantity in vaccines is truly miniscule).

    This academic paper alone cites more sources than we could here without making today’s newsletter longer than it already is:

    Vaccine Safety: Myths and Misinformation

    I have a perfectly good immune system, it can handle the disease: True or False?

    True! Contingently.

    In fact, our immune system is so good at defending against disease, that the best thing we can do to protect ourselves is show our immune system a dead or deactivated version of a pathogen, so that when the real pathogen comes along, our immune system knows exactly what it is and what to do about it.

    In other words, a vaccine.

    One subscriber who voted for “Vaccines are important but in some cases the side effects can be worse ” wrote:

    ❝In some ways I’m vacd out. I got COVid a few months ago and had no symptoms except a cough. I have asthma and it didn’t trigger a lot of congestion. No issues. I am fully vaccinated but not sure I’ll get one in fall.❞

    We’re glad this subscriber didn’t get too ill! A testimony to their robust immune system doing what it’s supposed to, after being shown a recent-ish edition of the pathogen, in deactivated form.

    It’s very reasonable to start wondering: “surely I’m vaccinated enough by now”

    And, hopefully, you are! But, as any given pathogen mutates over time, we eventually need to show our immune system what the new version looks like, or else it won’t recognize it.

    See also: Why Experts Think You’ll Need a COVID-19 Booster Shot in the Future

    So why don’t we need booster shots for everything? Often, it’s because a pathogen has stopped mutating at any meaningful rate. Polio is an example of this—no booster is needed for most people in most places.

    Others, like flu, require annual boosters to keep up with the pathogens.

    Herd immunity will keep us safe: True or False?

    True! Ish.

    But it doesn’t mean what a lot of people think it means. For example, in the UK, “herd immunity” was the strategy promoted by Prime Minister of the hour, Boris Johnson. But he misunderstood what it meant:

    • What he thought it meant: everyone gets the disease, then everyone who doesn’t die is now immune
    • What it actually means: if most people are immune to the disease (for example: due to having been vaccinated), it can’t easily get to the people who aren’t immune

    One subscriber who voted for “Vaccines are critical for our health; vax to the max! ” wrote:

    ❝I had a chiropractor a few years ago, who explained to me that if the general public took vaccines, then she would not have to vaccinate her children and take a risk of having side effects❞

    Obviously, we can’t speak for this subscriber’s chiropractor’s children, but this raises a good example: some people can’t safely have a given vaccine, due to underlying medical conditions—or perhaps it is not available to them, for example if they are under a certain age.

    In such cases, herd immunity—other people around having been vaccinated and thus not passing on the disease—is what will keep them safe.

    Here’s a useful guide from the US Dept of Health and Human Services:

    How does community immunity (a.k.a. herd immunity) work?

    And, for those who are more visually inclined, here’s a graphical representation of a mathematical model of how herd immunity works (you can run a simulation)!

    Stay safe!
