Many Are Cold, But Few Are Frozen

We asked you for your (health-related) view of ice baths, and got the above-depicted, below-described, set of responses:

  • About 31% said “ice baths are great for the health; we should take them”
  • About 29% said “ice baths’ risks outweigh their few benefits”
  • About 26% said “ice baths’ benefits outweigh their few risks”
  • About 14% said “ice baths are dangerous and can kill you; best avoided”

So what does the science say?

Freezing water is very dangerous: True or False?

True! Water close to freezing point is indeed very dangerous, and can most certainly kill you.

Fun fact, though: many such people are still saveable with timely medical intervention, in part because the same hypothermia that is killing them also slows down the process* of death

Source (and science) for both parts of that:

Cold water immersion: sudden death and prolonged survival

*and biologically speaking, death is a process, not an event, by the way. But we don’t have room for that today!

(unless you die in some sudden violent way, such as a powerful explosion that destroys your brain instantly; then it’s an event)

Ice baths are thus also very dangerous: True or False?

False! Assuming that they are undertaken responsibly and you have no chronic diseases that make it more dangerous for you.

What does “undertaken responsibly” mean?

Firstly, the temperature should not be near freezing. It should be 10–15℃, which for Americans is 50–59℉.

You can get a bath thermometer to check this, by the way. Here’s an example product on Amazon.

Secondly, your ice bath should last no more than 10–15 minutes. This is not a place to go to sleep.

What chronic diseases would make it dangerous?

Do check with your doctor if you have any doubts, as no list we make can be exhaustive and we don’t know your personal medical history, but the main culprits are:

  • Cardiovascular disease
  • Hypertension
  • Diabetes (any type)

The first two are for heart attack risk; the latter is because diabetes can affect core temperature regulation.

Ice baths are good for the heart: True or False?

True or False depending on how they’re done, and your health before starting.

For most people, undertaking ice baths responsibly, repeated ice bath use causes the cardiovascular system to adapt to better maintain homeostasis when subjected to thermal shock (i.e. sudden rapid changes in temperature).

For example: Respiratory and cardiovascular responses to cold stress following repeated cold water immersion

And because that was a small study, here’s a big research review with a lot of data; just scroll to where it has the heading“Specific thermoregulative adaptations to regular exposure to cold air and/or cold water exposure“ for many examples and much discussion:

Health effects of voluntary exposure to cold water: a continuing subject of debate

Ice baths are good against inflammation: True or False?

True! Here’s one example:

Winter-swimming as a building-up body resistance factor inducing adaptive changes in the oxidant/antioxidant status

Uric acid and glutathione levels (important markers of chronic inflammation) are also significantly affected:

Uric acid and glutathione levels during short-term whole body cold exposure

  • The Autoimmune Cure – by Dr. Sara Gottfried

    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.

    We’ve featured Dr. Gottfried before, as well as another of her books (“Younger”), and this one’s a little different, and on the one hand very specific, while on the other hand affecting a lot of people.

    You may be thinking, upon reading the subtitle, “this sounds like Dr. Gabor Maté’s ideas” (per: “When The Body Says No”), and 1) you’d be right, and 2) Dr. Gottfried does credit him in the introduction and refers back to his work periodically later.

    What she adds to this, and what makes this book a worthwhile read in addition to Dr. Maté’s, is looking clinically at the interactions of the immune system and nervous system, but also the endocrine system (Dr. Gottfried’s specialty) and the gut.

    Another thing she adds is more of a focus on what she writes about as “little-t trauma”, which is the kind of smaller, yet often cumulative, traumas that often eventually add up over time to present as C-PTSD.

    While “stress increases inflammation” is not a novel idea, Dr. Gottfried takes it further, and looks at a wealth of clinical evidence to demonstrate the series of events that, if oversimplified, seem unbelievable, such as “you had a bad relationship and now you have lupus”—showing evidence for each step in the snowballing process.

    The style is a bit more clinical than most pop-science, but still written to be accessible to laypersons. This means that for most of us, it might not be the quickest read, but it will be an informative and enlightening one.

    In terms of practical use (and living up to its subtitle promise of “cure”), this book does also cover all sorts of potential remedial approaches, from the obvious (diet, sleep, supplements, meditation, etc) to the less obvious (ketamine, psilocybin, MDMA, etc), covering the evidence so far as well as the pros and cons.

    Bottom line: if you have or suspect you may have an autoimmune problem, and/or would just like to nip the risk of such in the bud (especially bearing in mind that the same things cause neuroinflammation and thus, putatively, depression and dementia too), then this is one for you.

  • Relieve GERD and Acid Reflux with Stretches and Exercises

    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.

    Looking for relief from GERD or acid reflux? Today we’re featuring an amazing video by Dr. Jo, packed with stretches and exercises designed to ease those symptoms.

    Here’s a quick rundown, in case you don’t have time to watch the whole video.

    If you’re not familiar with GERD, you can find our simple explanation of GERD here. Or, if you’re on the other end of the spectrum and want to do a deeper dive on the topic, we reviewed a great book on the topic).

    1. Mobilize Your SEM Muscle

    The sternocleidomastoid (SEM) muscle, if tight, can aggravate acid reflux. Dr. Jo shows how to gently mobilize this muscle by turning your head while holding the SEM in place. It’s simple but effective.

    2. Portrait Pose Stretch

    Stretch out that SEM with the Portrait Pose. Place your hand on your collarbone, turn your head away, side bend, and look up. Hold for 30 seconds. You’ll feel the tension melting away.

    3. Seated Cat-Cow Motion

    Open up your stomach area with this easy exercise. Sit down, roll your body forward, arch your back (Cow), then curl your spine and tuck your chin (Cat). Alternate for 30 seconds and feel the difference.

    4. Quadruped Cat-Cow with Breathing

    Similar to the seated cat-cow, the quadruped cat-cow focuses on flexing the lower spine whilst on all fours. Bonus tip: focus on deep belly breathing during the exercise. This helps improve digestion and ease reflux symptoms.

    5. Exaggerated Pelvic Tilt

    Lie on your back and tilt your pelvis back and forth. This loosens up the abdominal area and helps everything flow better.

    6. Trunk Rotation

    Lie down, bend your knees, and rotate them to one side. Hold for 30 seconds, then switch sides. It’s a great way to relax and stretch your abdominal muscles.

    We know this is a quick overview (sorry if it seems rushed!), but if you have a few more minutes on your hand you can watch the whole video below.

    Feel better soon! And if you have any favorite tips or videos to share, email us at 10almonds.

  • Winter Wellness – by Rachel de Thample

    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.

    Winter is often the season of comfort foods and, in much of the Western world, there’s a holiday season slide of forgotten diets and instead sugar, alcohol, pastry, and the like.

    What de Thample does here is an antidote to all that, without sacrificing happiness and celebration.

    Before the recipes get started, she has a chapter on “food as medicine“, and to our immense surprise, proceeds to detail, accurately, many categories such as

    • Foods for immune health
    • Foods against inflammation
    • Foods for gut health
    • Foods against aging
    • Foods for energy levels
    • Foods against anxiety
    • Foods for hormonal balance

    …and so forth, with lists of ingredients that fit into each category.

    Then in the rest of the book, she lays out beautiful recipes for wonderful dishes (and drinks) that use those ingredients, without unhealthy additions.

    The recipes are, by the way, what could best be categorized as “fancy”. However, they are fancy in the sense that they will be impressive for entertaining, and (again, to our great surprise) they don’t actually call for particularly expensive/rare ingredients, nor for arcane methods and special equipment.Instead, everything’s astonishingly accessible to put together and easy to execute.

    Bottom line: if you’d like to indulge this winter, but would like to do so healthily, this is an excellent way to do so.

  • How Emotions Are Made – by Dr. Lisa Feldman Barrett

    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.

    We’ve previously reviewed Dr. Barrett’s (also good) book Seven And A Half Lessons About The Brain, and this one is very different, and of more practical use:

    The main thrust of the book is: the bioessentialist model of emotions is flawed; there is also no Platonic perfect form of any given emotion, and in fact emotions are constructed by the brain as a learned adaptive response.

    She argues this from the dual vectors of on the one hand hard sciences of affective neuroscience and clinical psychology, and on the other hand sociology and anthropology.

    In the category of criticism: Dr. Barrett, a very well-known and well-respected cognitive neuroscientist, is not an expert on sociology and anthropology, and some of her claims there are verifiably false.

    However, most of the book is given over the psychophysiology, which is entirely her thing, and she explains it clearly and simply while backing everything up with mountains of data.

    The usefulness of this book is chiefly: if we understand that emotions are not innate and are instead constructed adaptive (and sometimes maladaptive) neurological responses to stimuli and associations, we can set about rewiring things a little in accord with what’s actually more beneficial to us. The book also outlines how.

    Bottom line: if you’d like to be able to not merely manage emotions as they are, but also prune and/or grow them from the stem up, then this book provides a robustly scientific approach for doing that.

  • Parenting a perfectionist? Here’s how you can respond

    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 children show signs of perfectionism from early on. Young children might become frustrated and rip up their drawing if it’s not quite right. Older children might avoid or refuse to do homework because they’re afraid to make a mistake.

    Perfectionism can lead to children feeling overwhelmed, angry and frustrated, or sad and withdrawn.

    And yet perfectionism isn’t considered all bad in our society. Being called a “perfectionist” can be a compliment – code for being a great worker or student, someone who strives to do their best and makes sure all jobs are done well.

    These seemingly polarised views reflect the complex nature of perfectionism.

    Annie Spratt/Unsplash

    What is perfectionism?

    Researchers often separate perfectionism into two parts:

    1. perfectionistic strivings: being determined to meet goals and achieve highly
    2. perfectionistic concerns: worry about being able to meet high standards, and self-criticism about performance.

    While perfectionistic strivings can be positive and lead to high achievement, perfectionistic concerns can lead to a higher chance of children developing eating disorders or anxiety and depression, and having lower academic achievement.

    Children and adolescents may experience perfectionism in relation to school work, sport, performance in art or music, or in relation to their own body.

    Signs of perfectionistic concerns in children and adolescents may include:

    A range of genetic, biological and environmental factors influence perfectionism in children. And as a parent, our role is important. While research evidence suggests we can’t successfully increase positive perfectionistic strivings in our children, harsh or controlling parenting can increase negative perfectionistic concerns in children.

    Parents who are perfectionistic themselves can also model this to their children.

    So, how can we walk the line between supporting our child’s interests and helping them to achieve their potential, without pressuring them and increasing the risk of negative outcomes?

    Give them space to grow

    A great metaphor is the gardener versus the carpenter described by psychology professor Alison Gopnik.

    Instead of trying to build and shape our children by controlling them and their environment (like a carpenter), parents can embrace the spirit of the gardener – providing lots of space for children to grow in their own direction, and nourishing them with love, respect and trust.

    We can’t control who they become, so it’s better to sit back, enjoy the ride, and look forward to watching the person they grow into.

    However, there is still plenty we can do as parents if our child is showing signs of perfectionism. We can role model to our children how to set realistic goals and be flexible when things change or go wrong, help our children manage stress and negative emotions, and create healthy balance in our family daily routine.

    Set realistic goals

    People with perfectionistic tendencies will often set unattainable goals. We can support the development of flexibility and realistic goal setting by asking curious questions, for example, “what would you need to do to get one small step closer to this goal?” Identifying upper and lower limits for goals is also helpful.

    If your child is fixed on a high score at school, for example, set that as the “upper limit” and then support them to identify a “lower limit” they would find acceptable, even if they are less happy with the outcome.

    This strategy may take time and practice to widen the gap between the two, but is useful to create flexibility over time.

    If a goal is performance-based and the outcome cannot be guaranteed (for example, a sporting competition), encourage your child to set a personal goal they have more control over.

    We can also have conversations about perfectionism from early on, and explain that everyone makes mistakes. In fact, it’s great to model this to our children – talking about our own mistakes and feelings, to show them that we ourselves are not perfect.

    Talk aloud practices can help children to see that we “walk the walk”. For example, if you burn dinner you could reflect:

    I’m disappointed because I put time and effort into that and it didn’t turn out as I expected. But we all make mistakes. I don’t get things right every time.

    Manage stress and negative emotions

    Some children and adolescents have a natural tendency towards perfectionism. Rather than trying to control their behaviour, we can provide gentle, loving support.

    When our child or adolescent becomes frustrated, angry, sad or overwhelmed, we support them best by helping them to name, express and validate all of their emotions.

    Parents may fear that acknowledging their child’s negative emotions will make the emotions worse, but the opposite is true.

    Creating healthy balance

    The building blocks of healthy child development are strong loving family relationships, good nutrition, creative play and plenty of physical activity, sleep and rest.

    Perfectionism is associated with rigidity, and thinking that there is only one correct way to succeed. We can instead encourage flexibility and creativity in children.

    Children’s brains grow through play. There is strong research evidence showing that creative, child-led play is associated with higher emotion regulation skills, and a range of cognitive skills, including problem-solving, memory, planning, flexibility and decision-making.

    Play isn’t just for young children either – there’s evidence that explorative, creative play of any kind also benefits adolescents and adults.

    There is also evidence that getting active outdoors in nature can promote children’s coping skills, emotion regulation and cognitive development.

  • Surgery won’t fix my chronic back pain, so what 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.

    This week’s ABC Four Corners episode Pain Factory highlighted that our health system is failing Australians with chronic pain. Patients are receiving costly, ineffective and risky care instead of effective, low-risk treatments for chronic pain.

    The challenge is considering how we might reimagine health-care delivery so the effective and safe treatments for chronic pain are available to millions of Australians who suffer from chronic pain.

    One in five Australians aged 45 and over have chronic pain (pain lasting three or more months). This costs an estimated A$139 billion a year, including $12 billion in direct health-care costs.

    The most common complaint among people with chronic pain is low back pain. So what treatments do – and don’t – work?

    Opioids and invasive procedures

    Treatments offered to people with chronic pain include strong pain medicines such as opioids and invasive procedures such as spinal cord stimulators or spinal fusion surgery. Unfortunately, these treatments have little if any benefit and are associated with a risk of significant harm.

    Spinal fusion surgery and spinal cord stimulators are also extremely costly procedures, costing tens of thousands of dollars each to the health system as well as incurring costs to the individual.

    Addressing the contributors to pain

    Recommendations from the latest Australian and World Health Organization clinical guidelines for low back pain focus on alternatives to drug and surgical treatments such as:

    • education
    • advice
    • structured exercise programs
    • physical, psychological or multidisciplinary interventions that address the physical or psychological contributors to ongoing pain.

    Two recent Australian trials support these recommendations and have found that interventions that address each person’s physical and psychological contributors to pain produce large and sustained improvements in pain and function in people with chronic low back pain.

    The interventions have minimal side effects and are cost-effective.

    In the RESOLVE trial, the intervention consists of pain education and graded sensory and movement “retraining” aimed to help people understand that it’s safe to move.

    In the RESTORE trial, the intervention (cognitive functional therapy) involves assisting the person to understand the range of physical and psychological contributing factors related to their condition. It guides patients to relearn how to move and to build confidence in their back, without over-protecting it.

    Why isn’t everyone with chronic pain getting this care?

    While these trials provide new hope for people with chronic low back pain, and effective alternatives to spinal surgery and opioids, a barrier for implementation is the out-of-pocket costs. The interventions take up to 12 sessions, lasting up to 26 weeks. One physiotherapy session can cost $90–$150.

    In contrast, Medicare provides rebates for just five allied health visits (such as physiotherapists or exercise physiologists) for eligible patients per year, to be used for all chronic conditions.

    Private health insurers also limit access to reimbursement for these services by typically only covering a proportion of the cost and providing a cap on annual benefits. So even those with private health insurance would usually have substantial out-of-pocket costs.

    Access to trained clinicians is another barrier. This problem is particularly evident in regional and rural Australia, where access to allied health services, pain specialists and multidisciplinary pain clinics is limited.

    Higher costs and lack of access are associated with the increased use of available and subsidised treatments, such as pain medicines, even if they are ineffective and harmful. The rate of opioid use, for example, is higher in regional Australia and in areas of socioeconomic disadvantage than metropolitan centres and affluent areas.

    So what can we do about it?

    We need to reform Australia’s health system, private and public, to improve access to effective treatments for chronic pain, while removing access to ineffective, costly and high-risk treatments.

    Better training of the clinical workforce, and using technology such as telehealth and artificial intelligence to train clinicians or deliver treatment may also improve access to effective treatments. A recent Australian trial, for example, found telehealth delivered via video conferencing was as effective as in-person physiotherapy consultations for improving pain and function in people with chronic knee pain.

    Advocacy and improving the public’s understanding of effective treatments for chronic pain may also be helpful. Our hope is that coordinated efforts will promote the uptake of effective treatments and improve the care of patients with chronic pain.
