Personally, I don't think that having healthy relationships as a developer is much different than having healthy relationships as anyone else. As with any other technical job, it can be hard to explain exactly what your job is, but a bit of humor and an ELI5-style explanation goes a long way.
One thing specific to programmers is the ability to whip up a little program to help people. Someone spends an hour every day retyping lower-case data in uppercase? Take ten seconds and write them a program. Someone complains how they always forget to shut down their computer and waste electricity? Write them a widget to shut it down at 1am each night.
When I take a bit of time to write programs for people I care about, people are usually very grateful and vastly overestimate the difficulty of whatever I just did. As always, relevant xkcd: https://xkcd.com/1425/
