Cortisol Capers

Did you know that when the body is under stress, it produces a hormone called cortisol? The hormone provides energy that might be needed in a stressful situation.It also lowers the body's immune response to infections like influenza;  inflammation and inflammation-related responses like coughing, sneezing and fevers. So, while it lowers the immune response, there's a bit of an upside because it also depresses the things we don't like about the flu, for example; the coughing, the sneezing and the fever.

But when cortisol levels stay elevated - say, under periods of prolonged stress - the body may become less sensitive to it. When researchers at Carnegie Mellon tested this idea* by exposing healthy adults to cold viruses, they found that people who'd recently been through stressful experiences were most likely to show resistance to cortisol. They were also more likely to develop colds - and they produced cytokines, immune system components that promote inflammation and heighten the severity of symptoms.

Have brief periods of stress, and a correspondingly brief jump in your cortisol levels could allow you to operate more efficiently and even depress the symptoms of infections you get because of your correspondingly lowered immune system.

Have extended periods of stress, and all that cortisol in your system will do less and less good; in fact, your body will produce another chemical that will increase and heighten the severity of all the symptoms that cortisol fought.

I just learned that. And now I'm that much closer to understanding why, when my stress level goes from Defcon Three to Defcon Two (we're never at less than Defcon Three here at Casa Kaffyr,) my body's sclerodermically wonky immune system responds by inflaming my wrists, my toes, my ankles, my fingers, the tops of my feet and the backs of my hands,  making them so hot and sore that it hurts to wash my hands or put socks on.

We had our first negotiation session today. Guess how my joints have reacted?

But right now I'm kind of gleeful, all that notwithstanding. Not about the pain, but about what I learned.

I mean, yeah, the common wisdom (an oxymoronic phrase if ever there was one) has been that stress can lead to ailments. And, yeah, there are have been numerous studies linking stress to illness (which, I suppose, means that in this case the common wisdom isn't quite so oxymoronic as it might otherwise be aaaaaand I'm rambling). But reading about this study really helps me understand my own body, and gives me a more concrete idea of why - and, more importantly for me, how -  my own stress-illness connection works.


And yes, somehow that's more worth talking about than the day of negotiations.

Oh, and I'm really, really close to finishing Chapter 17. I know I said that earlier, but I'm even closer now. Really. Maybe by the end of the weekend. I feel positively breathless.


*Findings of the study were published in The Proceedings of the National Academy of Sciences.

I would even go so far as to say that I am pro-science (and I vote!).

Oh, and isn't there some theory that says too much cortisol for too long may also be a factor in depression?

And you vote? This Aussie is confused. What does voting have to do with science?

...to bumper stickers past, which said stuff like "I am pro-choice, and I vote". Back when bumper stickers were more popular (they're SO 20th century!).

Can be relevant in opposition to anti-science politics. There are genuinely politicans who will insist that global warming or evolution or rape-caused pregnancy don't exist and form policy based on those assumptions.

I guess the other part of my confusion is that here in Australia, EVERYBODY votes. So it isn't particularly noteworthy to declare that one votes.

If you don't vote, you get fined. I failed to vote in my council elections once, and I cheerfully paid the fine (about $50), because I totally agree with the idea of compulsory voting. IMHO, in a democracy, voting isn't a right, it's a duty.

It does make the political landscape quite different, I think. Instead of wooing the extremists (which in a voluntary-voting democracy are the ones most likely to vote at all) the politicians have to woo the moderates (the "swinging voters") because they are the ones most likely to change their minds about who to vote for.

I like you!

Well, that explains a lot about my summer. Hope the pain and inflammation is at least manageable.

Dude...see what you can do about that. I just recommend NOT shooting people. Tis an EASY fix, but it doesn't work for the interim and only leads to MORE stress later. But there is a lot to be said for THINKING it. And porn. Lots of porn.

I think I love BB, lol! *Sends a squish for him*

Mmmm...indeed. But we will not discuss my scribbles right now. They upset me, raise my cortisol levels (and my blood pressure) and make me want to hurt things that DO NOT EXIST ON THIS PLANE. Which is even more frustrating.

I am thinking of taking up knitting, fishing or drinking, though technically, they are all the same thing...

*Squishes you adoringly*
