🪶 The Navy uses natural rhythms to prevent "worse-than-drunk" performances (and you can, too).
I came across a Navy handbook that used the words "worse-than-drunk" to describe the performance of sailors in a state of circadian disruption. Thankfully, there are field-tested schedules to prevent this. Here are the rules:
nightshift is between 3-6 hours, never more!
eat at least one hot meal every day, with plenty of time to enjoy it (1.5-2.0 hours)
don’t require anyone to show up early (afternoon is the sweet compromise between night owls and morning larks)
Read the handbook here: CREW ENDURANCE HANDBOOK: A Guide to Applying Circadian-Based Watchbills (2017).
That's all for today, but you can always review the archive at nikkofujita.substack.com. I will share more about natural schedules and circadian rhythmicity in my upcoming emails📩.
As always, I’d love to hear your questions and experiences about this topic of circadian scheduling!
