Stress - 1. The Philosophy of Stress Flashcards
Stress
A mismatch between the demands made upon an individual and their ability to meet those demands
When does stress arise?
When you believe you can’t deal with all the demands placed upon you
What may the demands require of the individual?
They may require physical, mental or emotional adjustment
Stressor
Anything in life that makes you think you cannot cope with the demands placed upon you - anything that causes you stress.
Stressors are different for everyone
What creates stress?
Pressure
Positive and negative forms of pressure
A little bit of pressure can be productive as it may give you motivation and improve your performance
Excessive pressure can be unhealthy for the mind and body, leading to long term illness
Two stress pathways
Hypothalamic-pituitary-adrenal (HPS) axis
Sympatho-adrenomedullary (SAM) axis
Hypothalamic-pituitary-adrenal (HPS) axis pathway of stress
Hypothalamus activates the pituitary gland
ACTH is released, which acts on the adrenal cortex
Adrenal cortex releases cortisol
Sympatho-adrenomedullary (SAM) axis pathway of stress
Hypothalamus activates the sympathetic branch of the ANS
Adrenal medulla releases adrenaline and noradrenaline
Cortisol is a…
Hormone
When is cortisol released?
During the fight or flight response
At all times of the day for homeostasis
What is responsible for detecting if your blood has the correct level of cortisol in it?
Hypothalamus
Pituitary gland
What disease is associated with a lack of cortisol (little/no cortisol)?
Addison’s disease
What is a result of too much cortisol?
Cushing’s syndrome
How is cortisol good for the fight or flight response?
It restricts blood vessels, making it good as it increases blood pressure and heart rate which means that more blood is sent to the muscles
