GENERAL ADAPTATION SYNDROME
3 phase of physiological stress-response:
Alarm
First reaction when stressed is to FOCUS and your alarm turns on
®
Sympathetic Nervous System

Amygdala reacts
®
Sympathetic Nervous System (SNS) [flight or fight] releases
adrenaline via Hypothalamus
HPA-Axis activaates (Hypothalamic Pituitary Adrenal Axis)
Hypothalamus sends signal (CFR signal) to your pituitary
gland and it releases (ACTH) to the adrenal gland and
the adrenal gland released a cascade of glucocorticoids
which releases cortisol into your bloodstream
