A change from the regular routine of driving home in a hurry and being all worked up when you walk in the door could also help.

Back when I was a med surge floor nurse I found it very helpful to go by the local college and take a short run round the track a few times followed by a quick shower before going home.

One could also try just stopping when they leave work and meditating for a little while preforming some kind of mantra or ritual to help relieve the stress of the day and re-focus the mind.
