Lecture 3 Flashcards
Mental Health
What factors indicate failing mental health
listlessness
overwhelming sadness
inability to enjoy thing
What is stress
mental or physical responses to pressure
Positive vs. negative stress
positive (eustress) motivation, personal growth
negative (distress): mental and physical health decline
What happens to our body’s homeostasis when it perceives a stressor
- drop in homeostasis occurs (alarm stage)
- adaptation recourses mobilized to combat stressor, endocrine system comes into play (resistance stage)
- energy stores depleted (exhaustion stage)
define stressor
person, place, or thing we react to
can be physical, mental, environmental, or philosophical
Eustress vs. distress
Eustress: positive or beneficial stress
Distress: negative or harmful stress
What is the general adaptation syndrome
The body’s response to stress, three stages:
- Alarm: preparing for fight,
flight, and/or freeze - Resistance: Sympathetic vs. parasympathetic NS
- Exhaustion
What happens to the body during the general adaptation syndrome/stress?
more blood flows to the brain, senses sharpen, hearing increases, respiration increases, heart rate and blood pressure increase
The body’s physiological response to stress
Stressor disturbs homeostasis,
cerebral cortex triggers autonomic NS to prepare body for fight or flight. Hypothalamus controls epinephrine, ACTH, & cortisol
Sources of stress
inconsistent goals & behaviours, change, overload, pressure
psychoneuroimmunology (PNI)
Scienceofthe interaction between the mind and body, in particular with the immune system
common defence mechanisms
displacement, repression, regression, sublimation
technostress sources
information overload, constant learning, multitasking
Moderate vs. vigorous intensity heart rate %
Moderate: 50-70%
Vigorous: 70-85%
