I've been noticing that I'm more tired and need more downtime in days where I make, (or forced to make), critical decisions.
If I start the day by knowing what to do, then I don't really feel the burnout. For example, if I'm designing either a piece of hardware or firmware, and I know how to tackle the problem and it is just the matter of implementing it, I can code/design for 10 hours straight and when the workday ends, I still feel full of energy.
However, if the day is full of "decisions" (engineering or managerial), at the end of the day, I feel exhausted (and irritable, according to my family)
