Your body has a clock of sorts inside, but it is not very accurate.
A hotel without clocks, calendars, night and day indicators would allow you or your favorite researcher to see if your internal clock is fast or slow or random. Ports or tv cameras could track your natural activity cycles. To find
out how long you normally sleep without the sunrise or rooster resetting your clock daily. How long you work at a task etc.
Over a two week vacation you could be completely unhinged from the clock.
Only a wing or section of the hotel need be in lock down mode.
also. Maybe a TV series "The Chronically Disabled".

Blindness and Non-24

“The majority of patients with non-24 are totally blind, and the failure of entrainment is explained by an absence of photic input to the circadian clock.” [ytk, Jul 02 2014]

I don't think circadian rhythms quite work that way. It's not
so much that your body is on a natural cycle that would
continue more or less on its own but is “tweaked” by the
presence or absence of sunlight; it's really more like your
body is constantly adjusting based on external cues. For
example, morning light is stimulating, basically telling your
brain it's time to wake up and function. Also of note is the
fact that there is a strong link between total blindness and
non-24-hour sleep cycle disorder. |
|
| |
So removing these cues wouldn't really give you any sense
of how accurate your internal clock is, because it's not
really an internal clock in the first place. It might still be
an interesting experiment, however (though my guess is
“terrifying” and “disturbing” would be the adjectives more
likely to be used by subjects). [+] |

I haven't searched, nor will I most likely, due to a bad
case of laziness, but something inside of me says I bet
this exists, somewhere on one of those expensive,
very remote, tropical islands in the Pacific. |
|
| |
If I get a second wind today, or remember, I will
naturally search the internet world for this, come back
and delete this wordy anno. Thanks and have a special
Tuesday. |
|

Experimentation has shown that in the absence of external cues, your
species' circadian cycle is about 25 of your Earth hours, although
artificial lighting above minimal levels can severely bias the results. |
|
| |
I have the feeling you may have hit an a (possibly already in use somewhere) form of torture / imagine a prisoner who has no idea how long he's been held. |
|
| |
Throw in some periods of drug induced unconsciousness making sure to shave them (etc.) before waking them so they've no clear indication from such cues as to how long they've been out. |
|
| |
Obviously they would be kept in solitary with no access to mirrors (you don't want them marking time by their own changing appearance, plus (for men) having to shave by touch is it's own form of torture), TV (accept maybe taped episodes of The Prisoner, but with the last & one other random episode missing / because it's annoying & they'll wonder why) or papers (etc.). |

So... every hotel in Las Vegas then? : ] |
|
| |
Many a true word ... Vegas hotels are deliberately configured to give
just the sorts of psychological effects described; dissociation, loss of
time sense. |
|
| |
Maybe an annoyingly full of clocks and calenders hotel in Vegas would attract business? Right by the airport with cabs outside with motors running. Gotta Go. See ya. |
|
| |
Yes I was thinking of that. |
|
| |
Also mission impossible style prisoner detention & interrogation, maybe with fake newspapers & TV reports at some stage (i.e. of the death of someone you want information about). |
|
| |
I once found myself @ a new job away from home without an alarm (my watch @ the time was non-digital). |
|
| |
I'd recently seen a TV program that suggested a form of self visualisation. |
|
| |
So I imagined a number of stones dropping into a pond one after the other (7 stones for 7am) & the ripples spreading out (could have been arrows hitting a target at the appropriate clock position / pixies skipping rope / whatever) while repeating (in my head) the time it was, how many hours b4 I had to rise & the time I had rise: repeat until sleep claims you. |
|
| |
I really didn't expect it to work but it did, seemingly almost to the minute most days. |
|
| |
So there's something there & it can be fairly accurate over periods of a day or less (not that I'd ever trust to it if I actually had an alarm clock). |
|
| |
I doubt I could repeat the trick now though (neither as young or eager / my subconscious doesn't really care if I get into work on time or not any more). |
|
| |

Source please.
From what I have been able to glean, the pineal gland (light sensitive third eyeball) controls circadian rhythms in even those born profoundly blind. |
|
| |
minor quibble "...explained by an absence of photic input to the circadian clock.[1] However, the disorder can also occur in sighted people...." |
|
| |
Looks like they have confounded two different syndromes... |
|
| |
Maybe they did, but you can't conclude that from the
statement you quoted. The pathway in the brain
between the optic nerve and the circadian clock may
be damaged in such patients. |
|
| |
Well crap. I can't find the articles first read this information in. |
|
| |
Closest I could find;
"When people are completely isolated from environmental time cues, their circadian rhythms free run with a nearly 24-h cycle, generated by an internal body clock. Free-running temperature, cortisol, and melatonin rhythms have also been described in totally blind people, even though they were living in normal society and had access to abundant time cues; thus an intact visual system may be essential for synchronization of the circadian system. However, because of the small numbers of subjects studied, the incidence and clinical significance of circadian rhythm abnormalities among the blind has remained uncertain." fr. Pub Med |
|
| |
The original paper I read stated that even in people born without eyeballs whatsoever still had their own circadian ryhythms. |

RGCs -> melanopsin ->SCN -> SCG -> pineal gland -> melatonin supression |
|
| |
In the absence of light or melanopsin, melatonin is produced by the pineal gland. In humans, it induces an almost irresistible urge to sleep. Its primary function is to signal day length to the SCN so that it can synchronise the day/night cycle with:
•Endocrine rhythms
•Body temperature
•Glucose homeostasis
•Lipogenesis
•Locomotor activity |
|
| |
