I would totally agree with the "playing a musical instrument" as a method to wind down.

My working desk and all my IT gear is on one side of my home office. Behind me, the other half is racks of amps, keyboards and amps. During long compiles, installs or downloads or while waiting for a Slack response from a colleague, I will often just lean back and grab an instrument and play away for a few minutes.

Great way to reset the brain, plus change posture and breathing patterns.
