Unless you're operating dangerous machinery, you don't need as much sleep to work effectively at a warehouse. 6-7 hours and to recover physically and then a couple days off every so often to rest and you'll be fine. You don't have to think much, you just have to be strong and willing to exert effort.
Plus, getting to sleep at night when working a warehouse job is pretty easy, you're usually exhausted when you get home and have nothing to do but eat and sleep.
It's much different than a technical job that requires focus, concentration, inspiration, and mental discipline. Much different from work that requires social interaction with people. The mental states associated with lack of sleep can be disastrous in those environments.
