BEWARE-Fight or Flight May Be in Our Bones

Halloween ghosts and goblins may be our early warning that THE holiday season is here, raising our stress levels in preparation for gift shopping, cooking, cleaning, relatives, financial pressure . . .

The flight or fight response, our body’s way to prepare us to combat danger and keep us alive:

  • You breathe faster
  • Your heart rate increases
  • Your blood pressure increases
  • Your pupils dilate
  • The blood supply to your skin decreases
  • Your immune system shuts down

Just in time for Halloween . . .  scientists have identified a new hormone that is part of the stress response. It’s a protein called osteocalcin secreted by bone and is involved in triggering the body’s reaction to stress

“Gerard Karsenty, a physician and geneticist at the Columbia University Irving Medical Center, set out to investigate calcification a hardening of bone. In his study of this he eliminated osteocalcin from mice. While that did not change calcification as he had thought, the affected mice did not breed well and had excess fat.”

“Osteocalcin was in the blood of the mice, so Karsenty decided to see if it was a hormone. It was, and was involved in metabolism, fertility and muscle function, and maybe in brain development and thinking. He and others working on osteocalcin wondered why bone would produce a hormone. They thought perhaps bones evolved to help animals escape danger . . . . If so, bones may be part of the fight or flight response.”

Researchers . . .”found that mice without osteocalcin had a much lower fight or fight response, including less of an increase in heart rate, less increase in blood glucose, and less of a rise in temperature-all part of the physiological fight or flight response. This confirmed that osteocalcin played a role in the response.

“As they continued to learn about osterocalcins role, they thought  that what it was doing was activating the sympathetic part of the autonomic nervous system This part of the  autonomic nervous system is what triggers the fight or flight response. But injecting the hormone into the blood stream did not activate the sympathetic nerve, which was a surprise.”

“What was happening was the parasympathetic part of the autonomic nervous system, which triggers the “opposite” rest and digest response (which come into play when there is no threat), was affected-and it was suppressed.”  

So what osteocalcin does is turns off the parasympathetic autonomic nervous system (ANS) –and allowing the sympathetic ANS to take over and start the flight or fight response.”

 

“The notion that the parasympathetic nervous system is mediating the effects of osteocalcin on stress is a very interesting finding,” says James Herman, a neuroscientist at the University of Cincinnati, “I think what that means is that the way we currently understand stress is too simplistic.” He says that other chemical messengers may also play a role.”

“Karsenty’s team has also learned that stimulating part of the amygdala increases osteocalcin in the blood.”

Not all scientists are convinced of this work, and it will need to be replicated by others to be sure.  Maybe we’ll know more by next Halloween.

Fears I’ve Overcome and those to come . . .

Humans don’t learn to become terrified of spiders and snakes — we were hard-wired millions of years ago to fear them! 

Apparently, as a scientific study* concludes, the spider/snake specific response conferred an evolutionary advantage to our ancestors- who were able to identify and react to the creatures more quickly.

Reading this article made me reflect on my fears:

  • I used to be fearful of aliens coming to “get me”.  I am pretty sure that the time it would have been useful for them to study me has passed.
  • I used to be afraid that my mind would go before my body.  Since watching the decline of my own parents I’m now fearful that my mind will NOT go before my body.  It may be a blessing not to be aware of what my limitations are.
  • I used to be fearful people wouldn’t like me.  I now consider it a compliment that certain people don’t like me
  • I used to be fearful of snakes. I spent hours in my early 20’s watching snakes (behind a glass exhibit) noticing  how beautiful their markings were, how incredible it was that they navigated their way with their tongue and how remarkable their ability to move was.  I still am afraid of snakes. It’s hard-wired, you know.

  • I used to be fearful of not getting good grades in school.  I’ve got all the diplomas now I need . . .or want.
  • I used to be terrified of dying.  I’m not afraid of that since I’ve embraced the Baha’i belief about the celestial realm.
  • I used to be fearful of never having a boy ask me to dance at high school dances.  Now I fear that if anyone asked they’d find out I can’t dance
  • I used to be afraid of heights.  I took a Wilderness Course in my 30’s where we had to climb poles, walk across streams on tiny logs and fall backwards off ledges into people’s’ arms.  I am still afraid of heights.

Hey! My list of fears has really been whittled down!

All I’m afraid of now is that there are snakes in heaven, I will be a dance instructor for eternity and that heaven is REALLY HIGH up.

What are . . . or were . . . your fears ?

Frankly Freddie – No Trick, All Treat

It’s that time of year when my human-beings buy bags of candy in the pretext of passing it out on Halloween. Then they close all the curtains, turn off the lights and eat the candy themselves.

It’s also that time of year when Peggy & Judy revel in all things “gastly and ghoulish” but cover it up by only publicly displaying their drawings that are “sweet & lovable”

I’m putting their artistic endeavors up for sale on 

 Zazzle.com/catnipblog

“True Love is Seen Through the Heart” MUGS and More

All the proceeds go to buying me my own halloween treats which I shall eat on Halloween with the curtains closed and the lights out.

All the designs are on

  • Cups
  • Napkins
  • Paper plates
  • Mugs
  • AND special order (like t-shirts for real kids and adult kids)

Please buy a lot of these things because all we get is 5% of the sale and that doesn’t buy a lot of treats (human or canine).

Frankly,

Freddie Parker Westerfield, HMS

Head of Marketing & Sales
