Mythbusting The Mask Debate

We asked you for your mask policy this respiratory virus season, and got the above-depicted, below-described, set of responses:

  • A little under half of you said you will be masking when practical in indoor public places
  • A little over a fifth of you said you will mask only if you have respiratory virus symptoms
  • A little under a fifth of you said that you will not mask, because you don’t think it helps
  • A much smaller minority of you (7%) said you will go with whatever people around you are doing
  • An equally small minority of you said that you will not mask, because you’re not concerned about infections

So, what does the science say?

Wearing a mask reduces the transmission of respiratory viruses: True or False?

True…with limitations. The limitations include:

  • The type of mask
    • A homemade polyester single-sheet is not the same as an N95 respirator, for instance
  • How well it is fitted
    • It needs to be a physical barrier, so a loose-fitting “going through the motions” fit won’t help
  • The condition of the mask
    • And if applicable, the replaceable filter in the mask
  • What exactly it has to stop
    • What kind of virus, what kind of viral load, what kind of environment, is someone coughing/sneezing, etc

More details on these things can be found in the link at the end of today’s main feature, as it’s more than we could fit here!

Note: We’re talking about respiratory viruses in general in this main feature, but most extant up-to-date research is on COVID, so that’s going to appear quite a lot. Remember though, even COVID is not one beast, but many different variants, each with their own properties.

Nevertheless, the scientific consensus is “it does help, but is not a magical amulet”:

Wearing a mask is actually unhygienic: True or False?

False, assuming your mask is clean when you put it on.

This (the fear of breathing more of one’s own germs in a cyclic fashion) was a point raised by some of those who expressed mask-unfavorable views in response to our poll.

There have been studies testing this, and they mostly say the same thing, “if it’s clean when you put it on, great, if not, then well yes, that can be a problem”:

❝A longer mask usage significantly increased the fungal colony numbers but not the bacterial colony numbers.

Although most identified microbes were non-pathogenic in humans; Staphylococcus epidermidis, Staphylococcus aureus, and Cladosporium, we found several pathogenic microbes; Bacillus cereus, Staphylococcus saprophyticus, Aspergillus, and Microsporum.

We also found no associations of mask-attached microbes with the transportation methods or gargling.

We propose that immunocompromised people should avoid repeated use of masks to prevent microbial infection.❞

Wearing a mask can mean we don’t get enough oxygen: True or False?

False, for any masks made-for-purpose (i.e., are by default “breathable”), under normal conditions:

However, wearing a mask while engaging in strenuous best-effort cardiovascular exercise, will reduce VO₂max. To be clear, you will still have more than enough oxygen to function; it’s not considered a health hazard. However, it will reduce peak athletic performance:

Effects of wearing a cloth face mask on performance, physiological and perceptual responses during a graded treadmill running exercise test

…so if you are worrying about whether the mask will impede you breathing, ask yourself: am I engaging in an activity that requires my peak athletic performance?

Also: don’t let it get soaked with water, because…

Writer’s anecdote as an additional caveat: in the earliest days of the COVID pandemic, I had a simple cloth mask on, the one-piece polyester kind that we later learned quite useless. The fit wasn’t perfect either, but one day I was caught in heavy rain (I had left it on while going from one store to another while shopping), and suddenly, it fitted perfectly, as being soaked through caused it to cling beautifully to my face.

However, I was now effectively being waterboarded. I will say, it was not pleasant, but also I did not die. I did buy a new mask in the next store, though.

tl;dr = an exception to “no it won’t impede your breathing” is that a mask may indeed impede your breathing if it is made of cloth and literally soaked with water; that is how waterboarding works!

  • What is Ryeqo, the recently approved medicine for endometriosis?

    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 women diagnosed with endometriosis it is often a long sentence of chronic pain and cramping that impacts their daily life. It is a condition that is both difficult to diagnose and treat, with many women needing either surgery or regular medication.

    A medicine called Ryeqo has just been approved for marketing specifically for endometriosis, although it was already available in Australia to treat a different condition.

    Women who want the drug will need to consult their local doctor and, as it is not yet on the Pharmaceutical Benefits Scheme, they will need to pay the full cost of the script.

    What does Ryeqo do?

    Endometriosis affects 14% of women of reproductive age. While we don’t have a full understanding of the cause, the evidence suggests it’s due to body tissue that is similar to the lining of the uterus (called the endometrium) growing outside the uterus. This causes pain and inflammation, which reduces quality of life and can also affect fertility.

    Ryeqo is a tablet containing three different active ingredients: relugolix, estradiol and norethisterone.

    Relugolix is a drug that blocks a particular peptide from releasing other hormones. It is also used in the treatment of prostate cancer. Estradiol is a naturally occurring oestrogen hormone in women that helps regulate the menstrual cycle and is used in menopausal hormone therapy. Norethisterone is a synthetic hormone commonly used in birth control medications and to delay menstruation and help with heavy menstrual bleeding.

    All three components work together to regulate the levels of oestrogen and progesterone in the body that contribute to endometriosis, alleviating its symptoms.

    Relugolix reduces the overall levels of oestrogen and progesterone in the body. The estradiol compensates for the loss of oestrogen because low oestrogen levels can cause hot flushes (also called hot flashes) and bone density loss. And norethisterone blocks the effects of estradiol on the uterus (where too much tissue growth is unwanted).

    Is it really new?

    The maker of Ryeqo claims it is the first new drug for endometriosis in Australia in 13 years.

    But individually, all three active ingredients in Ryeqo have been in use since 2019 or earlier.

    Ryeqo has been available in Australia since 2022, but until now was not specifically indicated for endometriosis. It was originally approved for the treatment of uterine fibroids, which share some common symptoms with endometriosis and have related causes.

    In addition to Ryeqo, current medical guidance lists other drugs that are suitable for endometriosis and some reformulations of these have also only been recently approved.

    The oral medicine Dienogest was approved in 2021, and there have been a number of injectable drugs for endometriosis recently approved, such as Sayana Press which was approved in a smaller dose form for self-injection in 2023.

    How to take it and what not to do

    Ryeqo is a once-a-day tablet. You can take it with, or without food, but it should be taken about the same time each day.

    It is recommended you start taking Ryeqo within the first five days after the start of your next period. If you start at another time during your period, you may experience initial irregular or heavier bleeding.

    Because it contains both synthetic and natural hormones, you can’t use the contraceptive pill and Ryeqo together. However, because Ryeqo does contain norethisterone it can be used as your contraception, although it will take at least one month of use to be effective. So, if you are on Ryeqo, you should use a non-hormonal contraceptive – such as condoms – for a month when starting the medicine.

    Ryeqo may be incompatible with other medicines. It might not be suitable for you if you take medicines for epilepsy, HIV and AIDS, hepatitis C, fungal or bacterial infections, high blood pressure, irregular heartbeat, angina (chest pain), or organ rejection. You should also not take Ryeqo if you have a liver tumour or liver disease.

    The possible side effects of Ryeqo are similar to those of oral contraceptives. Blood clots are a risk with any medicine that contains an oestrogen or a progestogen, which Ryeqo does. Other potential side effects include bone loss, a reduction in menstrual blood loss or loss of your period.

    It’s costly for now

    Ryeqo can now be prescribed in Australia, so you should discuss whether Ryeqo is right for you with the doctor you usually consult for your endometriosis.

    While the maker has made a submission to the Pharmaceutical Benefits Advisory Committee, it is not yet subsidised by the Australian government. This means that rather than paying the normal PBS price of up to A$31.60, it has been reported it may cost as much as $135 for a one-month supply. The committee will make a decision on whether to subsidise Ryeqo at its meeting next month.

    Correction: this article has been updated to clarify the recent approval of specific formulations of drugs for endometriosis.The Conversation

    ❝Hi, do you have anything helpful on avoiding PFAs?❞

    PFAS, or perfluoroalkyl and polyfluoroalkyl substances, are “forever chemicals” made specifically to avoid degradation of industrial and chemical products. Which is great for providing stain and water resistance, but not so great for our bodies or the environment.

    To go into all the harms they cause would take a main feature (maybe we will, one of these days), but suffice it to say, they’re not good, and range from cancer and insulin resistance to hypertension and reduced immune response.

    To answer your question in a nutshell, avoiding them completely would be almost impossible, but we can reduce our exposure a lot by avoiding single-use food/drink products that have been waterproofed, e.g. paper/bamboo straws, utensils, cups, dishes, take-out containers, etc.

    Also, anything advertised as “stain-resistant” that you suspect should be quite stainable by nature, is probably good to avoid too.

    For more detailed information than we have room for here today, here’s a helpful overview:

  • Is Fast Food Really All That Bad?

    Yes, yes it is. However, most people misunderstand the nature of its badness, which is what causes problems. The biggest problem is not the acute effects of one afternoon’s burger and fries; the biggest problem is the gradual slide into regularly eating junk food, and the long-term effects of that habit as our body changes to accommodate it (of which, people tend to focus on subcutaneous fat gain as it’s usually the most visible, but that’s really the least of our problems).

    Cumulative effects

    There are, of course, immediate negative effects too, and they’re not without cause for concern. Because of the composition of most junk food, it will almost by definition result in immediate blood sugar spikes, rising insulin levels, and a feeling of fatigue not long afterwards.

    • Within a week of regularly consuming junk food, gut bacteria will change, resulting in moderate cravings, as well as a tendency towards depression and anxiety. Mood swings are likely, as are the gastrointestinal woes associated with any gut microbiota change.
    • Within two weeks, those effects will be greater, the cravings will increase, energy levels will plummet, and likely skin issues may start to show up (our skin mostly works on a 3-week replacement cycle; some things can show up in the skin more quickly or slowly than that, though).
    • Within three weeks, the rest of our blood metrics (e.g. beyond blood sugar imbalances) will start to stray from safe zones. Increased LDL, decreased HDL, and the beginnings of higher cardiovascular disease risk and diabetes risk.
    • Within a month, we will likely see the onset of non-alcoholic fatty liver disease, and chronic inflammation sets in, raising the risk of a lot of other diseases, especially immune disorders and cancer.

    If that seems drastic, along the lines of “eat junk food for a month and get cancer”, well, it’s an elevated risk, not a scheduled diagnosis, but the body is constantly rebuilding itself, for better or for worse, and if we sabotage its efforts by consuming a poor diet, then it will be for worse.

    The good news is: this works both ways, and we can get our body back on track in fairly short order too, by enjoying a healthier diet; our body will be thrilled to start repairing itself. And of course, all these effects, good and bad, are proportional to how well or badly we eat. There’s a difference between doing a “Supersize Me” month-long 100% junk food diet, and “merely” getting a junk food breakfast each day and eating healthily later.

    In short, if your diet is only moderately bad, then you will only be moderately unwell.

  • Fluoride Toothpaste vs Non-Fluoride Toothpaste – 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 fluoride toothpaste to non-fluoride toothpaste, we picked the fluoride.

    Why?

    Fluoride is indeed toxic; that’s why it’s in toothpaste (to kill things; namely, bacteria whose waste products would harm our teeth). However, we are much bigger than those bacteria.

    Given the amount of fluoride in toothpaste (usually under 1mg per strip of toothpaste to cover a toothbrush head), the amount that people swallow unintentionally (about 1/20th of that, so about 0.1mg daily if brushing teeth twice daily), and the toxicity level of fluoride (32–64mg/kg), then even if we take the most dangerous ends of all those numbers (and an average body size), to suffer ill effects from fluoride due to brushing your teeth, would require that you brush your teeth more than 23,000 times per day.

    Alternatively, if you were to ravenously eat the toothpaste instead of spitting it out, you’d only need to brush your teeth a little over 1,000 times per day.

    All the same, please don’t eat toothpaste; that’s not the message here.

    However! In head-to-head tests, fluoride toothpaste has almost always beaten non-fluoride toothpaste.

    Almost? Yes, almost: hydroxyapatite performed equally in one study, but that’s not usually an option on as many supermarket shelves.

    We found some on Amazon, though, which is the one we used for today’s head-to-head. Here it is:

    Boka Fluoride-Free Toothpaste

    However, before you rush to buy it, do be aware that the toxicity of hydroxyapatite appears to be about twice that of fluoride:

    Scientific Committee on Consumer Safety Opinion On Hydroxyapatite (Nano)

    …which is still very safe (you’d need to brush your teeth, and eat all the toothpaste, about 500 times per day, to get to toxic levels, if we run with the same numbers we discussed before. Again, please do not do that, though).

    But, since the science so far suggests it’s about twice as toxic as fluoride, then regardless of that still being very safe, the fluoride is obviously (by the same metric) twice as safe, hence picking the fluoride.

  • For many who are suffering with prolonged grief, the holidays can be a time to reflect and find meaning in 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.

    The holiday season is meant to be filled with joy, connection and celebration of rituals. Many people, however, are starkly reminded of their grief this time of year and of whom – or what – they have lost.

    The added stress of the holiday season doesn’t help. Studies show that the holidays negatively affect many people’s mental health.

    While COVID-19-related stressors may have lessened, the grief from change and loss that so many endured during the pandemic persists. This can cause difficult emotions to resurface when they are least expected.

    I am a licensed therapist and trauma-sensitive yoga instructor. For the last 12 years, I’ve helped clients and families manage grief, depression, anxiety and complex trauma. This includes many health care workers and first responders who have recounted endless stories to me about how the pandemic increased burnout and affected their mental health and quality of life.

    I developed an online program that research shows has improved their well-being. And I’ve observed firsthand how much grief and sadness can intensify during the holidays.

    Post-pandemic holidays and prolonged grief

    During the pandemic, family dynamics, close relationships and social connections were strained, mental health problems increased or worsened, and most people’s holiday traditions and routines were upended.

    Those who lost a loved one during the pandemic may not have been able to practice rituals such as holding a memorial service, further delaying the grieving process. As a result, holiday traditions may feel more painful now for some. Time off from school or work can also trigger more intense feelings of grief and contribute to feelings of loneliness, isolation or depression.

    Sometimes feelings of grief are so persistent and severe that they interfere with daily life. For the past several decades, researchers and clinicians have been grappling with how to clearly define and treat complicated grief that does not abate over time.

    In March 2022, a new entry to describe complicated grief was added to the Diagnostic and Statistical Manual of Mental Disorders, or DSM, which classifies a spectrum of mental health disorders and problems to better understand people’s symptoms and experiences in order to treat them.

    This newly defined condition is called prolonged grief disorder. About 10% of bereaved adults are at risk, and those rates appear to have increased in the aftermath of the pandemic.

    People with prolonged grief disorder experience intense emotions, longing for the deceased, or troublesome preoccupation with memories of their loved one. Some also find it difficult to reengage socially and may feel emotionally numb. They commonly avoid reminders of their loved one and may experience a loss of identity and feel bleak about their future. These symptoms persist nearly every day for at least a month. Prolonged grief disorder can be diagnosed at least one year after a significant loss for adults and at least six months after a loss for children.

    I am no stranger to complicated grief: A close friend of mine died by suicide when I was in college, and I was one of the last people he spoke to before he ended his life. This upended my sense of predictability and control in my life and left me untangling the many existential themes that suicide loss survivors often face.

    How grieving alters brain chemistry

    Research suggests that grief not only has negative consequences for a person’s physical health, but for brain chemistry too.

    The feeling of grief and intense yearning may disrupt the neural reward systems in the brain. When bereaved individuals seek connection to their lost loved one, they are craving the chemical reward they felt before their loss when they connected with that person. These reward-seeking behaviors tend to operate on a feedback loop, functioning similar to substance addiction, and could be why some people get stuck in the despair of their grief.

    One study showed an increased activation of the amygdala when showing death-related images to people who are dealing with complicated grief, compared to adults who are not grieving a loss. The amygdala, which initiates our fight or flight response for survival, is also associated with managing distress when separated from a loved one. These changes in the brain might explain the great impact prolonged grief has on someone’s life and their ability to function.

    Recognizing prolonged grief disorder

    Experts have developed scales to help measure symptoms of prolonged grief disorder. If you identify with some of these signs for at least one year, it may be time to reach out to a mental health professional.

    Grief is not linear and doesn’t follow a timeline. It is a dynamic, evolving process that is different for everyone. There is no wrong way to grieve, so be compassionate to yourself and don’t make judgments on what you should or shouldn’t be doing.

    Increasing your social supports and engaging in meaningful activities are important first steps. It is critical to address any preexisting or co-occurring mental health concerns such as anxiety, depression or post-traumatic stress.

    It can be easy to confuse grief with depression, as some symptoms do overlap, but there are critical differences.

    If you are experiencing symptoms of depression for longer than a few weeks and it is affecting your everyday life, work and relationships, it may be time to talk with your primary care doctor or therapist.

    A sixth stage of grief

    I have found that naming the stage of grief that someone is experiencing helps diminish the power it might have over them, allowing them to mourn their loss.

    For decades, most clinicians and researchers have recognized five stages of grief: denial/shock, anger, depression, bargaining and acceptance.

    But “accepting” your grief doesn’t sit well for many. That is why a sixth stage of grief, called “finding meaning,” adds another perspective. Honoring a loss by reflecting on its meaning and the weight of its impact can help people discover ways to move forward. Recognizing how one’s life and identity are different while making space for your grief during the holidays might be one way to soften the despair.

    When my friend died by suicide, I found a deeper appreciation for what he brought into my life, soaking up the moments he would have enjoyed, in honor of him. After many years, I was able to find meaning by spreading mental health awareness. I spoke as an expert presenter for suicide prevention organizations, wrote about suicide loss and became certified to teach my local community how to respond to someone experiencing signs of mental health distress or crisis through Mental Health First Aid courses. Finding meaning is different for everyone, though.

    Sometimes, adding a routine or holiday tradition can ease the pain and allow a new version of life, while still remembering your loved one. Take out that old recipe or visit your favorite restaurant you enjoyed together. You can choose to stay open to what life has to offer, while grieving and honoring your loss. This may offer new meaning to what – and who – is around you.
