The Biological Effects of Anxiety on the Body
In order to understand why long-term stress can be bad, we need to understand what immediate effect stress has on our bodies. Under stress, the hypothalamus-pituitary-adrenal system (HPA axis) is activated. The hypothalamus releases corticotrophin-releasing-hormone (CRH). CRH stimulates the pituitary gland. The pituitary then secretes adrenocorticotrophic hormone (ACTH). The Adrenal cortex then produces the stress hormone cortisol in humans.
Cortisol activates the fight-or-flight response. The sympathetic nervous system shuts down anything that your body doesn’t need during a traumatic event where you might need to fight or run away from a threat. That means your stomach stops digesting, you stop producing semen / ovulating, your immune system – which requires a huge amount of energy – slows way down. Tissue repair – also another drain on energy – halts. Activation of the sympathetic nervous system leads to release of the adrenaline (epinephrine) and noradrenaline (norepinephrine). These hormones circulate through the body and increase rate of the heart and of glucose metabolism – that gets the oxygen and energy flowing so you can use your limbs for fight or flight.
Cortisol is the hormone that prepares the body for fight-or-flight; thus, it is a good hormone to have around in an immediate danger. However, if stress continues, and cortisol is not turned off, the long term effects of suppression of vital bodily functions is quite detrimental to the body. Usually, after immediate stress, the cortisol has a feedback inhibition mechanism, in which it signals to slow its own production. However, if the stress continues for too long, cortisol’s feedback inhibition loop can be deactivated; thus allowing the adrenal cortex to continue pumping out cortisol and keeping the physiological effects of the sympathetic nervous system still active.
Since the immune system is inhibited by the sympathetic nervous system, individuals experiencing long-term stress are susceptible to infection by viruses and bacteria.
The best known physical side effect of stress is cardiovascular problems. As mentioned earlier in this post, the sympathetic nervous system increases heart-rate so that blood pumps more quickly throughout the body. Not only can this increase blood pressure directly, but it can also lead to damage of the blood vessel walls. The high blood pressure leads to tiny tears in the blood vessel walls. These tears are susceptible to accumulating circulating “junk” such as particles of fat and cholesterol. This accumulation – pictured n yellow above – can decrease blood flow through the vessel, or completely block flow as seen above. When the heart doesn’t get enough oxygen, then a heart attack may occur. Another problem with decreased blood flow is that if the brain doesn’t get enough oxygen, this can cause a stroke.
As you can see, stress can have a huge impact on your health. Doesn’t that stress you out?

Personality Disorders – Cluster B
Narcissistic personality disorder is one of the disorders that would be dropped if the diagnosis switched to a dimensional rather than cluster approach.
Because there is a lot of public interest in borderline personality disorder and antisocial / psychopathy, I will mention those Cluster B disorders in another post.

The Biology of Desire, by Marc Lewis

Lewis also points out that although medication and therapy generally help the individual to give up alcohol to begin with, there is a very high relapse rate. And that is because although the individual doesn’t want the negative effects of his addiction, he has not yet accepted the choice to give up the drug.
Nonfiction Book Pairings
This week’s Nonfiction November prompt given at Regular Ruminations is book pairings.
Half of a Yellow Sun follows 3 characters: Ugwu, a village boy who is taken in by some politically-inclined academics as a house boy; Olanna, Ugwu’s mistress and a rich heiress; and Richard, a British expat who desperately wants to be accepted by the Biafrans as one of them. The stories of these three characters are superbly and tragically woven together on a backdrop of war, racial hatred, and famine.
This is one of the most impressive books I’ve read in quite a while. The characters were so deep that I felt I knew them. The events described had an eerie realism to them that comes from the author’s intimate knowledge of the history and people. This is one of those books that makes you feel like every incident described is important and well-planned. This is a story not only of war, but of people–their dreams, their loves, their fears, their strengths and weaknesses. Half of a Yellow Sun is a must-read for anyone interested in international literature.
(Those two paragraphs were stolen from my review on the old blog in July of 2012.)
I have not had the opportunity to read There Was a Country yet, but it is the memoir of Chinua Achebe, social activist and author of Things Fall Apart. This book is the story of Achebe’s experience during the Biafra war. It’s been sitting on Mt. TBR ever since it was released.
I thought I’d add in a NF/NF/NF pairing as well, since it’s one that I’ve been considering. Lawrence in Arabia and From Beirut to Jerusalem are both histories of the Middle East. Seven Pillars of Wisdom is T. E. Lawrence – Lawrence of Arabia’s – memoir of his time spent in Arabia during WWI. I own two of these books, but am too intimidated to start on this journey.
Maybe I’ll make it a goal to read these non-fiction books – and perhaps re-read Half of a Yellow Sun before next year’s Nonfiction November. I could even do a readalong of these books, if anybody would like to join in. Though I know all of them are pretty intense and “read like a textbook” which is something that I’ve seen complained about by many participants of Nonfiction November. So I doubt I’ll get any takers.

| The Gilgamesh Epic and Old Testament Parallels by Alexander Heidel |
I wasn’t a huge fan of this translation, though it’s a classic that many scholars use as one of their base translations. It, like the Foster translation, is in fragmented verse. Only, it didn’t have the annotations. And the typeset in my book was difficult to read. I’d say the benefit of reading this book rather than the Norton Critical Edition is that it is a classic translation and includes Heidel’s analysis about Old Testament parallels.
