Disable work email from my personal devices, redirect unknown phone numbers to voicemail (including "unknown" phone numbers), block news sites by way of adblock on my computers, shut down my computer when not in use (so I think twice about turning it back on), cancel cable service, put my cellphone on vibrate, go for walks, do some physical labor, engage in hobbies that mix what I enjoy with something physical like robotics.
I am more relaxed during my personal time by disconnecting from the outside world and focusing on something outside of my mind (something that is not conceptual or virtual). There is definitely something about balancing personal and interpersonal time and internal and external engagements to create a healthy existence.
