1
Q

Stress definition

A

The body’s response to a real or interpreted threat (physical, psychological, environmental) that leads to a disruption in the body’s homeostasis

Q

Cellular stress examples

A

Toxins, extreme temperature changes, mechanical damage that leads to cellular damage, imbalance between free radicals and antioxidants, etc (related to exposure to environmental stimuli)

Q

Eustress vs distress

A

Eustress can actually strengthen certain physiological functions (immunity) while distress can impair physiological function/cause imbalance

Q

Allostatic load

A

Q

Three main body systems involved in the stress response

13
Q

What happens when the HPA axis is activated?

A

The hypothalamus releases corticotropin releasing hormone (CRH) which signals the pituitary gland to release adrenocorticotropic hormone (ACTH) which causes the adrenals to release cortisol

Hypothalamus - Pituitary - Adrenals for the eventual release of cortisol

Q

Cortisol impact on blood pressure and blood sugar

A

Increases blood pressure to provide add’l blood to muscles
Increases blood glucose levels by activating the metabolic pathway called gluconeogenesis (where non-carbohydrate substrates are used to create glucose)

Q

What is released when the SNS is activated in response to stress?

A

Epinephrine/adrenaline and norepinephrine/noradrenaline which increases blood sugar levels, heart rate, and heart contractions

16
Q

What role does the PSNS play in stress response?

A

Helps the body recover after the stressor is gone

17
Q

What gland releases oxytocin during stress response and what impact does this have on the body?

A

Released by pituitary gland and helps buffer the effects of stress throughout the body
-protects cardiovascular system and relaxes blood vessels
-natural anti-inflammatory
-makes one crave connection with others/seek support

18
Q

Examples of non-essential bodily functions that are shut down during times of stress

A

Digestion, reproductive function, protein synthesis, bone formation, aspects of immune system, kidney function, growth

19
Q

What is hormesis and what are some examples?

A

The adaptive response of cells and organisms to moderate intermittent stress - generally favorable

Examples - cold plunges, saunas, exercise, fasting

20
Q

What % of human disease is repeated to activation of the stress response system?

A

75-90%

21
Q

Stress and ghrelin relationship

A

Stress and rise in cortisol causes rise in ghrelin causing the body to crave energy-dense food. Also reduces insulin sensitivity contributing to high blood sugar (if chronic, can contribute to blood sugar disreg, weight gain, Type 2 diabetes)

22
Q

Stress and the immune system

A

Stress suppresses normal immune function by causing a decline in the number of the body’s protective immune cells from prolonged, hyper activation of the immune system

23
Q

Stress and inflammation

A

Inflammation during stress is caused by a disruption in glucocorticoid (steroid hormone w/ anti-inflammatory effects) receptors

24
Q

What are the effects of oxidative stress?

A

Cellular damage, accelerated aging, development of disease

25
Q

What is oxidation/oxidative stress?

A

Oxidation = natural process that occurs in body during physical activity, detox, and immune response. Can result in oxidative stress if not kept in balance. Oxidized molecules (free radicals) are unstable and missing an electron and will steal electrons from healthy molecules creating a cascade

26
Q

Role of antioxidants

A

Antioxidants have an extra electron that can neutralize free radicals while remaining stable after doing so - can help mitigate oxidative stress!

27
Q

Examples of sources that stimulate the generation of free radicals

A

Cigarette smoke, mold, alcohol, air, cooking at high temperatures/heating oils repeatedly or past smoke/boiling points
