It's my understanding that our ideas of eight hours of continuous sleep window may be an artifact of the industrial revolution and electrification. Meaning it may not be ideal for us, but just the assumption that we've become accustom to in modern times. There are lots of old writing (Ben Franklin etc.) that refer to their "second sleep" ie, they sleep for a few hours, get up and do some work, and then go back to sleep for a few hours more. If anyone has more concrete information on this, I'd be interested.
- kstrauser 2y agoThat's a valid sleep mode for some people. My wife wakes up in the middle of the night, reads for a bit, then goes back to sleep. That works for her. I absolutely cannot do this. When I fall asleep, I stay asleep for 7-8 hours and only then wake up. In the times where I've been unable to get that uninterrupted sleep. In the case of the Navy, I can guarantee that 6+6 shifts didn't come about because of advanced sleep research, but because "it was good enough for me and now it's good enough for them".
- bumby 2y agoI don't know it's origination, but I suspect the 6+6 was probably a result of having the ability to split operations of a 24 hour day into even crews (not much different than the civilian 8 hour allowing factory work to be split into 3 shifts). How they rationalize it after the fact is a different story.
