Infants, elders, shift workers#
The people for whom the nap is least optional
Until now, in one line#
The course has mostly concerned healthy adults on a standard day.
That was a convenience. This week it goes.
Three groups, one pattern#
| Group | The claim | The access |
|---|---|---|
| Infants and children | polyphasic by default | provided, then withdrawn |
| Older adults | nighttime sleep fragments | read as decline |
| Shift workers | measurable occupational hazard | frequently prohibited |
Strength of claim does not predict permission.
Infants and children#
- polyphasic by default, consolidating over years
- naps here are uncontroversial and institutionally provided
- provision stops at an age set by school timetables
Not by anything developmental.
Older adults#
Nighttime sleep fragments with age, and daytime sleep often returns.
The interesting part is the interpretation: the same behaviour that is developmentally normal in a child is read as decline in an older person.
Sometimes medicalised.
Shift workers#
The clearest case in the course.
- circadian misalignment is a measurable occupational hazard
- documented consequences for error rates and long-term health
- rostered napping demonstrably helps
Strongest claim, least access#
The group with the best evidence is the group most often forbidden
Why#
Safety-critical industries frequently prohibit on-shift sleep outright.
Week 7’s explanation applies directly, unchanged:
The objection is to how it looks, not to what it does.
Where it was fixed, and how#
Aviation is the case worth studying.
Controlled rest on the flight deck was regulated into existence, against industry resistance.
Not bought. Not encouraged. Required.
Who is missing from this list#
- carers
- people with chronic illness or disability
- anyone whose fatigue is contested rather than assumed
Strong claim, no access — and not yet a policy question anyone has taken up.
Tell me which group you’d argue for#
Across all three groups, permission to sleep in the day correlates with social position and not with physiological need. The nap pod cannot fix this, because it was never the kind of problem a purchase addresses.
