Thank you for all your answers.

Crankin, that's what I meant, when they hear someone is being active or "doing sports" they think about a small biketour on the weekend. And it's ok, I guess they are right most of the time. Most people consider themselves "active" and think that they "eat well" even if they don't - and probably doctors are used to this.
Finding a physician that is more used to treating active people or even an athlete herself so that she can relate to what we do - I guess this would be great.

As far as I know, high bp is not common in DHs family, but he told me that he had high bp as teenager, so genetics could be a factor.

Regarding his job, DH cut back one work hour the last few days and slept a little longer than usual. He cut back on coffee. I don't know how long this will last, but I guess it won't do any harm
I tried to de-stress him a bit, took him for a small biketour in the evening and made some good-night tea.

Emily, this article is really interesting. Strange how different studies sometimes come to contradicting results. I think I will just continue to use enough salt to taste while not overdoing it - this seems to make the most sense to me.
