I’d say it depends on your role and how much you need to sleep.
I’m in busy production management role where we work 4 on 4 off, this being 2 days and then 2 nights. Managers work a minimum of 13 hour shifts with handovers at both ends of the shift and can be lucky to get more than one break in a shift on occasion.
Be disciplined with your routines and try to get as much sleep as you need.
I struggle with quality sleep and also find myself eating at all hours. This combines to pile on a few pounds and before you know it you’re less fit than you’ve ever been!
Some guys that work in my team love it, they run their machines, get their breaks, come in and go home on time, sleep all day/night and repeat, then have 4 quality days off.
