I'm not sure hun tbh. My uncle suffers with high blood pressure and had to go on tablets (he is only 40ish and has had high blood pressure since his mid 30's).
I know he had a lot of time off work at one stage but he is quite a stressy person.
Probably best to maybe go with your hubby to the docs and get some advice on what to avoid, like stressful events.
Sorry I'm not much help but

to you xx
