I think, the page is somewhat uncritical. Why should it be a "disorder" if someone sleeps later or sooner than most of the other people? These people are a discriminated minority just like gays. Not everyone has to be like all the rest. There are even groups of them who fight for their rights, see http://delta-t.org

I think, DSPSer even are an evolutionary adjustment. Imagine two tribes of people in stone age. One tribe has a guy who is always alert in the middle of the night, the other tribe has not. Now some hungry, wild predator comes by. Which of the two groups has a better chance of survival?

I fully agree with this. It's clearly not a "disorder" if someone isn't conforming to, frankly, mediocre ideals for when people "should" sleep. It's without basis in fact, thus pseudoscience. As you can discern from research, MOST people are not morning people, so most people aren't going to consider going to bed at 10 p.m. normal. In fact that's incredibly early unless you're 5 years old. Considering that chronotypes and other research have proven beyond any doubt that whether you're a morning or night person isn't a "choice," but a genetic and biological fact of different people, then it cannot be a disorder to be an evening person any more than it's a disorder to be born gay or born black or born Indian. It's discrimination, nothing more, and obviously unworthy in 2017 of being counted as any sort of "disorder" as it's pure philosophy and has nothing to do with science. — Preceding unsigned comment added by 71.236.163.247 (talk) 08:22, 12 April 2017 (UTC)[reply]

This page is awesome and contains a lot of great information. However I believe that we can improve this page by expanding on a few areas:

-Under the "Extrinsic type" subheading, shift work is briefly mentioned. I believe that we can easily expand on this, as shift work has been well studied in terms of it's effect on circadian rhythms. Also, I believe that the phenomenon of jet lag should definitely be included in this section, as it has just as much a negative effect on circadian rhythms as shift work does. The effects that events like these have on our rhythms could easily be added and expanded upon.

-->Shift work can contribute to increased risks related to sleep and fatigue, cardiovascular disease, cancer, and human accidents. (Akerstedt & Wright, 2009) Nearly 20% of the labor force wordwide participates in shiftwork. Management strategies for the effects of shiftwork include approaches to promote sleep, adaptation to the imposed work schedule, and subsequent wakefulness. Additional studies are needed to further the understanding of the mechanisms underlying the health risks of shift work (Wyatt, 2013).

-Under the "Normal circadian rhythms" subheading, experiments pertaining to free-running rhythms are briefly mentioned. A famous study involving Michel Siffre could easily be presented and cited as evidence for this piece, which in turn could be placed under it's own subheading or section.

-->A study was done on three young male subjects polygraphicall recorded while isolated in caves for 5-6 months. Control recordings were performed just before and after their isolation. 2 out of the 3 patients developed variable latencies due to free-running rythms, with cycles up to 34 hr of wakefulness and 14hr of sleep, completely losing the 24-hour cycle. Upon exiting the cave, external zeitgebers such as light were effective in returning subjects to their normal rythms (Siffre et al., 1974).

-I like the introduction to this page, especially the second paragraph which explains circadian rhythms and what all physiological factors theses rhythms influence and control- including body temperature, alertness, appetite, hormone secretion, etc. I think that we could add how our rhythms affect these things. For example, we could elaborate on how body temperature fluctuates throughout the circadian cycle, showing that certain times of the day and cycle correspond to increases and decreases in body temperature. This could be done for many of the physiological mechanisms and provide the reader with a greater understanding of circadian rhythms, and thus be able to better understand how disorders of these rhythms can have negative impacts on the body.

-Overall a great article and a fun read. Thanks!

Thanks for your review. I think that many of the additions you suggest are addressed in, for example, Circadian rhythms, Shift work sleep disorder, Jet lag etc. --Hordaland (talk) 18:42, 1 June 2014 (UTC)[reply]

Caffine at bedtime pushes back the body's circadian clock.

Headline-1: Caffeine at Night Does More Than Keep You Up Late

QUOTE: "SCIENTISTS FIND THAT ESPRESSO 3 HOURS BEFORE BEDTIME DELAYS THE CIRCADIAN CLOCK ... caffeine has another physiological impact on sleep by delaying the body's natural surge in the production of the sleep hormone melatonin, which in turn pushes back the body's circadian clock. "To our surprise, no one had really tested this question," one of the researchers tells NPR. "What we're seeing here now is another way that caffeine impacts our physiology that we didn't know about before in humans." The problem in this case is that the circadian clock is "present in cells throughout our entire body," says the researcher. "It's in your fat cells; it's in your muscle cells." Messing with it appears to play a role in a wide range of health problems, from obesity to cancer. Many studies have recently suggested that bright light at night, especially the blue light emanating from our screens, impedes melatonin production." -- AstroU (talk) 09:44, 18 September 2015 (UTC) -- PS: FYI for future editing.[reply]

  • Bright light therapy is used to advance or delay sleep, depending on how (in which direction) the circadian rhythm needs to be shifted. This is accomplished by use of exposure to high-intensity light from the sun, a light box (up to 10,000 lux) or wearable light therapy device (up to 500 lux) for a duration of 30–60 minutes daily. The time of day is dependent on whether an advance or a delay is required; light upon awakening moves the sleep period earlier, light late in a person's day moves it later.[citation needed]

CRSD

[edit]

@Jytdog:

Currently CRSD redirects to Circadian rhythm sleep disorder. This is also the acronym for Copper River School District. The acronym "CRSD" was clearly stated in the "redirect" template as the reason for the redirect. I would like for a link to the school district to be re-established from "CRSD".
