Some health news to round off the week:

The Infection That Leads To Heart Failure

It’s long been held that, for example, flossing reduces heart disease risk, with the hypothesis being that if plaque bacteria enter the blood stream, well, that’s an even worse place for plaque bacteria to be. Now, with much more data, attention has turned to

1. actual infections, and
2. actual heart failure

Way to up the ante! And, it holds true regardless of what kind of infection. So, you might think that a UTI, for example, is surely “downstream” and should not affect the heart, but it does. Because of this, researchers currently believe that it is not the infection itself, so much as the body’s inflammation response to infection, that leads to the heart failure. Which is reasonable, because, for example, atherosclerosis is made mostly not of cholesterol itself, but rather mostly of dead immune cells that got stuck in the cholesterol.

Moreover, it’s not so much about the acute inflammatory response (which is almost always a good thing, circumstantially), but rather that after cases where an infection managed to take hold, the immune system can then often stay on high alert for many years alter. Long COVID is an obvious recent example of this, but it’s hardly a new phenomenon; see for example post-polio syndrome, and consider how many more such post-infection maladies are likely to exist that never got a name because they flew under the radar or got diagnosed as fibromyalgia or something (fibromyalgia is a common diagnosis doctors give when they acknowledge something’s wrong, and it causes pain and exhaustion, but they don’t know what, and it appears to be stable—so while it can be helpful to put a name to the collection of symptoms, it’s a non-diagnosis diagnosis on the doctors’ part. It’s saying “I diagnose you with hurty tiredness”).

The take-away from all this? Avoid infections, for your heart’s sake, and if you do get an infection, take it seriously even if it’s minor. The safe amount of infection is “no infection”.

Cold Water Immersion: Hot Or Not?

The evidence is clear for some benefits; for others, not so much:

• It’s great (if you’re already in fair health, and definitely not if you have a heart condition) to improve circulation and stress response
• There may be some benefits to immune function, but however reasonable the hypothesis, actual evidence is thin on the ground
• The oft-hyped mood benefits are a) marginal b) short-lived, with benefits fading after 3 months of regular cold baths/showers/etc

The Unspoken Trials Of Going To The Gym (While Being A Woman)

Public health decision-makers often think that getting people to go to the gym more is a matter of public information, or perhaps branding. Some who have their thinking heads on might even realize that there may be economic factors for many. But for women, there’s an additional factor—or rather, an additionally prominent factor. The study we’ll link started with this observation (please read it in the voice of your favorite nature documentary narrator):

❝Despite an increase in gym memberships, women are less active than men and little is known about the barriers women face when navigating gym spaces.❞

What then, of these shy, elusive creatures that make up a mere 51% of the world’s population?

A medium-sized (n=279) study of women, of whom 84% being current gym-goers, reported often feeling “judged for their appearance or performance, as well as having to fight for space in the gym and to be taken seriously, while navigating harassment and unsolicited comments from men”

Even gym attire becomes an issue:

❝Aligning with previous literature, women often chose attire based on comfort and functionality. However, their choices were also influenced by comparisons with others or fear of judgement for wearing non-branded attire or looking too put together. Many women also chose gym attire to hide perceived problem areas or avoid appearance concerns, including visible sweat stains.❞

…which main seem silly; you’re at the gym, of course you’re going to sweat, but if you’re the only one with visible sweat stains, then there can be social consequences (bad ones).

Similarly, there’s a “damned if you do; damned if you don’t” when it comes to working out while fat—on the one hand, society conflates fatness with laziness; on the other, it can be extra intimidating to be the only fat person in a gym full of people who look like they’re going to audition for a superhero movie.

❝In the gym, just like in other areas of life, women often feel stuck between being seen as ‘too much’ and ‘not enough’, dealing with judgement about how they look, how they perform, and even how much space they take up. Even though the pressure to be super thin is decreasing, the growing focus on being muscular and athletic is creating new challenges. It is pushing unrealistic standards that can negatively affect women’s body image and overall well-being.❞

Writer’s note: I live a few minutes walk from my nearest gym, and I work out at home instead. This way, if I want to do yoga in my pajamas, I can. If I want to use my treadmill naked and watch my T+A bounce in the mirror, I can. If I want to lift weights in the dress I happened to be wearing, I can. Alas that I can’t swim at home!
