Well, I'm shocked--the man page doesn't give the answer?  

The fact that you can restart most processes with a SIGHUP is one of
those things that you just pick up along the way.  (It might be
different for the real gurus, but I mean the average person.)  Godwin
and I once had a correspondence about this very thing, when I made an
effort to find reference to it in some man pages--I think the OpenBSD
man page for signals might have had it, but they were the only one.

(Which is typical, they tend to have the best docs--they are the only
ones, for example, who bother to give an example of how to use
ifconfig--when I was a newcomer, I thought the man page, especially the
Linux ones, which tend to be the worst, was very little help.)

I usually try killall -SIGHUP sshd or whatever.  Anyway, don't worry if
you don't find it in a man page, though it wouldn't suprise me if it's
in OpenBSD's.  (I haven't checked, and I'm at work right now, but I'd
say there's a reasonable chance.)
