It's the opposite for me. If disconnecting and taking a break provides relief, the problem was overwork/exhaustion/fatigue and not "burnout". Burnout is something deeper that and more closely related to depression, and no amount of time off will fix it if you just end up coming back to the same environment.

Strangely enough, the fix to burnout can be finding different/more engaging work to help overcome the cynicism and sense of hopelessness.
