I know that anxiety leads to high blood pressure due to elevations of adrenaline.
It also can also increase cortisol levels which as the Mayo Clinic points out:
- curbs functions that would be nonessential or detrimental in a fight-or-flight situation
- alters immune system responses
- increases sugars (glucose) in the bloodstream and
- suppresses the digestive system, the reproductive system and growth processes.
According to Jayne Leonard in Medical News Today (2019):
having long-term high blood pressure — which doctors refer to as hypertension — can cause people to feel anxious about their health and future.
And, while interestingly she points out that:
some medications for anxiety can increase blood pressure
I am not talking about fears about health after being diagnosed with high blood pressure due to arterial atherosclerosis for example.
What I am referring to is the possibility of stress/anxiety being caused by the high blood pressure, maybe creating an elevation of adrenaline or cortisol through some kind of neural connection with the heart and blood supply.
Is this possible?
Anxiety can lead to aggression and/or other behaviours — as an example (as @starckman pointed out in the comments) there is a study by Kouchaki & Desai (2015) that showed a link between anxiety and unethical behavior in the workplace — and I was wondering if high blood pressure not caused by mental health problems could lead to those mental health problems and possibly elevate the blood pressure problems in a vicious cycle.
