As I understand it (but I'm no doctor), stress can really affect BP. If your husband's job is very stressful--to the point of affecting his health--it might be an opportunity to figure out how to lower that stress. I left a job that was so stressful that I had multiple health problems from the stress. I did not have high BP, but I serious bruxism, nearly chronic back and hip pain, and extra weight. I left that job and those issues resolved themselves.

Just something to think about as you and your husband figure out how best to be healthy and happy.
