HPA Axis vs. Fight Flight Freeze

[peter.g15]

Hello all,
Reading about the HPA axis and cortisol and the fight flight freeze response.

Can someone explain the link between these two systems (if there is one). What i mean is does the FFF response occur at the same time as the HPA axis, however since the FFF response cannot be sustained, the HPA axis continues? Or is it that the FFF response is activated, and then the HPA axis becomes active?

Thank you very much

Put simply, the HPA axis is like support for the flight-fight response when there is persistent activation. This is for the reason that the FF response uses up a lot of the body's resources, and to ensure that there is enough to continue the response, the HPA axis is activated to release hormones (e.g cortisol) that increase these reserves.

Also you should note that the HPA axis is activated in situations in which the individual is subjected to a prolonged stressor, while fight or flight is in more temporary situations.

For example,
If you miss a bus to school, your FF response could be activated.
But like if your gf dumps you and you're still not over her HPA could come into play. you know when u got that drake shizz on repeat 24/7
