Unit 1 - The Definition of Health
sympathetic nervous system
"Fight or flight" ... unhealthy to have activated for long extended periods of time
parasympathetic nervous system
"Rest and digest"
The Placebo Effect: Cons
- ppl can miss necessary treatment - positive effects can fade over time - physical health isn't always treated -clouds clinical data
Hormones
Chemicals produced by certain organs or tissues in the body
Immune System responsible for:
Combatting illness and infections, remove foreign organisms/toxic substances from body
Bodily functions of sympathetic
Dilate outlets, increased heart rate, sweat gland stimulation, digestion decreased, adrenal glands stimulated, etc
Medical Model process
Disease detected through systematic process of observation, description, and differentiation ... in accordance with standard medical procedures, data driven
Disability adjusted life years
Estimated number of years lost due to ill health, disability, or early death
Mental health ___________ affects your overall health
Mental health completely affects your overall health
quality of life
No medical factors that effect a persons wellbeing ... self reported
Brains thoughts and feelings centers connect to
Other nerve cells in brain/body , hormone producing tissues and organs, and immune cells
Wellness Model Process/what's assessed?
Physical Wellness, emotional wellness, spiritual wellness, occupational wellness, social wellness, intellectual wellness ! (PESOS!)
Placebo can __________ psychosomatic illness, can ________ somatic symptom disorder
Placebo can lessen psychosomatic illness, and can cure somatic symptom disorder
Burden of Disease (BOD)
Quantifies the gap between ideal life span and an ill individuals current situation
Function of hormones
Regulates specific biological functions... feelings control hormones and hormones control feelings ... your thoughts can have an affect on your body though activation of the sympathetic nervous system or release of hormones
constant arousal of ANS can dause
Sleep problems, muscle tension, GI problems, increased cardiovascular disease

Immune system can be influenced by
The mind via nervous and endocrine systems ... stress/negative moods can weaken the immune system

DALY = ___ + ___
YLD + YLL (years lived with disability + years of life lost)
Medical Model definition of Health
absense of one or more of the 5 Ds
Psychosomatic Illness
any physical illness aggravated by a mental factor (emotions, anxiety, stress) Modern medicine doesn't treat psychosomatic illnesses directly ... drugs suppress symptoms but do not cure
How ANS is affected
can be affected by thoughts/feelings and overwhelmed people can have constant arousal of ANS
Five D's
death, disease, discomfort, disability, dissatisfaction
nocebo effect
harmless thing that causes harm because you believe it's harmful
autonomic nervous system (ANS)
nerves regulate body's physiological functions without conscious control
ANS has 2 parts:
parasympathetic and sympathetic
Somatic Symptom Disorder
physical symptom without any bodily disease or injury present (ex: depression/anger can cause pain, fatigue, nausea, diarrhea, etc)
Placebo can only help:
symptoms that can be modulated by the mind, which is still a big component for patient comfort, happiness, and wellbeing
Physicians should not prescribe placebos because
-might not work for all patients - no legal protection
Pharmalogical Conditioning
-placebo triggers response brain like a real drug - brain learns to associate taking a pill w/ relief ... chemicals kick in - only works if the drug is acting on something the brain is able to do naturally
The Placebo Effect: Pros
-tool to test new drugs (ethical concerns) - minimize bias in testing - relief from pain/ailments - expectations of recovery can decrease discomfort
