Wrong Arm Position = Wrong Measurement Of Blood Pressure

This is especially important to know if you measure your own blood pressure at home.

Even if you don’t, it’s still good to know this as healthcare providers also can (and often will) do it wrong, especially if they are under time pressure (e.g. they need to get you out of their office and the next person in):

From the heart

Many things can change our blood pressure, and even gravity changes (considerably!) our blood pressure locally.

For example, even with good circulation, so long as we are in the Earth’s gravity under normal conditions (e.g. not skydiving, not riding a rollercoaster, etc), our blood pressure will always be higher below our heart, and lower above it, because gravity is pulling our blood downwards; this is also why if your circulation is not good, you may feel light-headed upon sitting up or standing up, as the bloodstream takes a moment to win a battle against gravity. This is also why blood rushes to your head if you are hanging upside down—increasing the local blood pressure in your head, which unlike your feet, isn’t used to it, so you feel it, and the effect may be visible from the outside, too.

When it comes to having your arm above or below your heart, the difference is less pronounced as it’s only a small change, but that small change can make a big difference:

  • If the cuff is above heart level → Lower blood pressure reading.
  • If the cuff is below heart level → Higher blood pressure reading.
  • Every 1-inch difference causes a 2 mmHg change in readings.

For the reading to be accurate, the blood pressure cuff therefore needs to be at the same height as your heart.

You may be thinking: “my heart is bigger than an inch; do I aim for the middle?”

And the answer is: ideally the cuff should be at the same height as the right atrium of the heart, which is under the midpoint of the sternum.

However, your arm needs to be supported at that height, because if you have to keep it there using your own power, that will mean a tensing of your muscles, and increase in both heart rate and blood pressure. In fact, studies cited in the video found:

  • Unsupported arm, in healthy patients → Systolic +8 mmHg, Diastolic +7 mmHg.
  • Unsupported arm, in high blood pressure patients → Systolic +23 mmHg, Diastolic +10 mmHg.

Some other considerations; firstly, correct sitting posture:

  • Sit upright with back support
  • Feet flat on the floor, legs uncrossed
  • Arm should be outward from the body and, as per the above explanation, supported (armrest, table, etc.)

And finally, you should be relaxed and at rest.

For example, your writer here is due for a regular checkup in a couple of weeks, and usually when I go there, I will have walked a couple of miles to get there, then bounced cheerfully up 6 flights of stairs. However, for this appointment, I will need to make sure to arrive early, so that I have time for my (so far as I know, happy and healthy) heart to return to its resting pulse and blood pressure.

Also, if you are anything like this writer, the blood pressure cuff activating is not a relaxing experience (and so invites a higher pulse and blood pressure), so it’s better to take three readings and then discard the first one, and record the average of the second two (I do it this way at home).

Similarly, if a medical environment in general is stressful for you, then taking two minutes to do a little mindfulness meditation, or even just breathing exercises, can be good.

  • Chipotle Chili Wild Rice

    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 is a very gut-healthy recipe that’s also tasty and filling, and packed with polyphenols too. What’s not to love?

    You will need

    • 1 cup cooked wild rice (we suggest cooking it with 1 tbsp chia seeds added)
    • 7 oz cooked sweetcorn (can be from a tin or from frozen or cook it yourself)
    • 4 oz charred jarred red peppers (these actually benefit from being from a jar—you can use fresh or frozen if necessary, but only jarred will give you the extra gut-healthy benefits from fermentation)
    • 1 avocado, pitted, peeled, and cut into small chunks
    • ½ red onion, thinly sliced
    • 6–8 sun-dried tomatoes, chopped
    • 2 tbsp extra virgin olive oil
    • 2 tsp chipotle chili paste (adjust per your heat preferences)
    • 1 tsp black pepper, coarse ground
    • ½ tsp MSG or 1 tsp low-sodium salt
    • Juice of 1 lime

    Method

    (we suggest you read everything at least once before doing anything)

    1) Mix the cooked rice, red onion, sweetcorn, red peppers, avocado pieces, and sun-dried tomato, in a bowl. We recommend to do it gently, or you will end up with guacamole in there.

    2) Mix the olive oil, lime juice, chipotle chili paste, black pepper, and MSG/salt, in another bowl. If perchance you have a conveniently small whisk, now is the time to use it. Failing that, a fork will suffice.

    3) Add the contents of the second bowl to the first, tossing gently but thoroughly to combine well, and serve.

    Enjoy!

  • Big Think’s #1 Antidote To Aging

    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.

    Why This Video Is Important

    A lot of what we talk about here at 10almonds is focused on healthy aging. We want you – our lovely readers – to not only live for a long time, but also be healthy enough to enjoy that “long time”.

    We’ve talked about anything from Dr. Greger’s eight anti-aging interventions, to the specific benefits of resveratrol or metformin in combatting aging, to even reducing stress-induced aging.

    So, why is this video important? It goes beyond just talking about what we know about living longer, but also focuses on how we should live longer; there’s a big difference between living a long life but never leaving your house vs. living a long life beyond your front door.

    The Takeaways

    The core message that Big Think wants to convey is that our lifestyle is our best bet in slowing the aging process. Our bodies are adaptive systems, responding positively to healthy lifestyle choices. They focus on exercise: regular physical activity increases healthspan, consequently extending lifespan.

    A key takeaway is the difference between physical activity and exercise. While any movement counts as physical activity, exercise is a deliberate, health-focused activity. It benefits the brain by releasing growth factors that strengthen critical areas like the hippocampus and prefrontal cortex.

    The video encourages embracing physical activity in any form available to you, from gardening to walking. The goal isn’t to hit a specific number of steps but to stay active in a way that suits your lifestyle.

    Science may not solve death. Yet. But focusing on maintaining a healthy, functioning state for as long as possible is the real victory in the battle against aging. And, at the moment, exercise seems to be our best bet:

  • Stop Overthinking – by Nick Trenton

    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 book is exactly what it says on the tin. We are given twenty-three techniques to relieve stress, stop negative spirals, declutter your mind, and focus on the present, in the calm pursuit of good mental health and productivity.

    The techniques are things like the RAIN technique above, so if you liked that, you’ll love this. Being a book rather than a newsletter, it also takes the liberty of going into much more detail—hence the 200 pages for 23 techniques. Unlike many books, it’s not packed in fluff either. It’s that perfect combination of “to the point” and “very readable”.

    If you’ve read this far into the review and you’re of two minds about whether or not this book could be useful to you, then you just might be overthinking it

  • Get Past Executive Dysfunction

    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.

    In mathematics, there is a thing called the “travelling salesman problem”, and it is hard. Not just subjectively; it is classified in mathematical terms as an “NP-hard problem”, wherein NP stands for “nondeterministic polynomial”.

    The problem is: a travelling salesman must visit a certain list of cities, order undetermined, by the shortest possible route that visits them all.

    To work out what the shortest route is involves either very advanced mathematics, or else solving it by brute force, which means measuring every possible combination order (which number gets exponentially larger very quickly after the first few cities) and then selecting the shortest.

    Why are we telling you this?

    Executive dysfunction’s analysis paralysis

    Executive dysfunction is the state of knowing you have things to do, wanting to do them, intending to do them, and then simply not doing them.

    Colloquially, this can be called “analysis paralysis” and is considered a problem of planning and organizing, as much as it is a problem of initiating tasks.

    Let’s give a simple example:

    You wake up in the morning, and you need to go to the bathroom. But the bathroom will be cold, so you’ll want to get dressed first. However, it will be uncomfortable to get dressed while you still need to use the bathroom, so you contemplate doing that first. Those two items are already a closed loop now. You’re thirsty, so you want to have a drink, but the bathroom is calling to you. Sitting up, it’s colder than under the covers, so you think about getting dressed. Maybe you should have just a sip of water first. What else do you need to do today anyway? You grab your phone to check, drink untouched, clothes unselected, bathroom unvisited.

    That was a simple example; now apply that to other parts of your day that have much more complex planning possible.

    This is like the travelling salesman problem, except that now, some things are better if done before or after certain other things. Sometimes, possibly, they are outright required to be done before or after certain other things.

    So you have four options:

    • Solve the problem of your travelling-salesman-like tasklist using advanced mathematics (good luck if you don’t have advanced mathematics)
    • Solve the problem by brute force, calculating all possible variations and selecting the shortest (good luck getting that done the same day)
    • Go with a gut feeling and stick to it (people without executive dysfunction do this)
    • Go towards the nearest item, notice another item on the way, go towards that, notice a different item on the way there, and another one, get stuck for a while choosing between those two, head towards one, notice another one, and so on until you’ve done a very long scenic curly route that has narrowly missed all of your targetted items (this is the executive dysfunction approach).

    So instead, just pick one, do it, pick another one, do it, and so forth.

    That may seem “easier said than done”, but there are tools available…

    Task zero

    We’ve mentioned this before in the little section at the top of our daily newsletter that we often use for tips.

    One of the problems that leads to executive function is a shortage of “working memory”, like the RAM of a computer, so it’s easy to get overwhelmed with lists of things to do.

    So instead, hold only two items in your mind:

    • Task zero: the thing you are doing right now
    • Task one: the thing you plan to do next

    When you’ve completed task zero, move on to task one, renaming it task zero, and select a new task one.

    With this approach, you will never:

    • Think “what did I come into this room for?”
    • Get distracted by alluring side-quests

    Do not get corrupted by the cursed artefact

    In fantasy, and occasionally science fiction, there is a trope: an item that people are drawn towards, but which corrupts them, changes their motivations and behaviors for the worse, as well as making them resistant to giving the item up.

    An archetypal example of this would be the One Ring from The Lord of the Rings.

    It’s easy to read/watch and think “well I would simply not be corrupted by the cursed artefact”.

    And then pick up one’s phone to open the same three apps in a cycle for the next 40 minutes.

    This is because technology that is designed to be addictive hijacks our dopamine processing, and takes advantage of executive dysfunction, while worsening it.

    There are some ways to mitigate this:

    Rebalancing Dopamine (Without “Dopamine Fasting”)

    …but one way to avoid it entirely is to mentally narrate your choices. It’s a lot harder to make bad choices with an internal narrator going:

    • “She picked up her phone absent-mindedly, certain that this time it really would be only a few seconds”
    • “She picked up her phone for the eleventy-third time”
    • “Despite her plan to put her shoes on, she headed instead for the kitchen”

    This method also helps against other bad choices aside from those pertaining to executive dysfunction, too:

    • “Abandoning her plan to eat healthily, she lingered in the confectionary aisle, scanning the shelves for sugary treats”
    • “Monday morning will be the best time to start my new exercise regime”, she thought, for the 35th week so far this year

    Get pharmaceutical or nutraceutical help

    While it’s not for everyone, many people with executive dysfunction benefit from ADHD meds. However, they have their pros and cons (perhaps we’ll do a run-down one of these days).

    There are also gentler options that can significantly ameliorate executive dysfunction, for example:

  • The Recipe For Empowered Leadership – by Doug Meyer-Cuno

    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 is not a “here’s how to become a leader, you young would-be Machiavelli”; it’s more a “so you’re in a leadership role; now what?” book. The book’s subtitle describes well its contents: “25 Ingredients For Creating Value & Empowering Others”

    The book is written with the voice of experience, but without the ego-driven padding that accompanies many such books. Especially: any anecdotal illustrations are short and to-the-point, no chapter-long diversions here.

    Which we love!

    Equally helpful is where the author does spend a little more time and energy: on the “down to brass tacks” of how exactly to do various things.

    In short: if instead of a lofty-minded book of vague idealized notions selling a pipedream, you’d rather have a manual of how to actually be a good leader when it comes down to it, this is the book for you.

  • Asparagus vs Eggplant – 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 asparagus to eggplant, we picked the asparagus.

    Why?

    In terms of macros, they’re very similar. Technically asparagus has twice the protein, but it’s at 2.2g/100g compared to eggplant’s 0.98g/100g, so it’s not too meaningful. They’re both mostly water, low in carbs, with a little fiber, and negligible fat (though eggplant technically has more fat, but again, these numbers are miniscule). For practical purposes, the two vegetables are even in this category, or if you really want decisive answers, a tiny margin of a win for asparagus.

    In the category of vitamins, asparagus is much higher in vitamins A, B1, B2, B3, B5, B6, B9, E, & K, as well as choline. Eggplant is not higher in any vitamins. A clear win for asparagus.

    When it comes to minerals, asparagus is much higher in calcium, copper, iron, phosphorus, selenium, and zinc, while eggplant is a little higher in manganese. Another easy win for asparagus.

    Lastly, asparagus wins on polyphenols too, with its high quercetin content. Eggplant does contain some polyphenols, but in such tiny amounts that even added up they’re less than 7% of what asparagus has to offer in quercetin alone.

    Obviously, enjoy both, though! Diversity is healthy.
