Talk:Cortisol awakening response

Sudden interest

Cannot add this fact to the article since it is original research but "Cortisol awakening response" is a "hot" research topic. Type these words with the quotation marks in to PubMed and 85 (when I write) articles appear. 27 roughly a third are 2009 76 since 2005 and so the last four years.--LittleHow (talk) 05:35, 23 August 2009 (UTC)

I think it is because it has only recently been discovered. This is discussed in some of the reviews, I believe, so you should be able to find a ref for it. --sciencewatcher (talk) 04:52, 29 April 2014 (UTC)

Incompatible

These two statements would seem to be mutually exclusive:

• Alarm clock vs. spontaneous waking: there is no difference on days when people woke up spontaneously or used the alarm clock.[1]
• Cortisol awakening response is larger for those: waking up to a working day compared to work- free weekend day.[20][21]

- Hordaland (talk) 07:02, 23 August 2009 (UTC)

This may explain the confusion. This source says:

Salivary cortisol levels on waking did not differ by gender or socioeconomic position, or between work and weekend days. However, the cortisol awakening response (defined as the difference between waking and 30 min later) was greater on work than weekend days

according to what Hordaland says the source is misinterpreted in the article. salivary cortisol levels on waking is NOT the result of CAR, instead CAR is measured as elevation of C 30 min later, compared to the baseline of the waking level. the false info:"Alarm clock vs. spontaneous waking: there is no difference on days when people woke up spontaneously or used the alarm clock.[1] " must be deleted. 80.99.38.199 (talk) 19:53, 14 April 2018 (UTC).

okay, instead of deleting the wrong line I rewrote it. since it is part of a larger section in the article that talks about different factors from the point of view how they affect the CAR, I changed it to reflect the finding (of the source) that although the waking level of cortisol is unchanged by alarm clock waking, the CAR is stronger when waking to an alarm clock than when waking spontaneously. 80.99.38.199 (talk) 19:53, 14 April 2018 (UTC).

The source we use clearly says that the use of alarm clock has no effect. If you have a source saying it does have an effect, you should add it. However there is no confusion here...see Hordaland's comment above for the reason: it's due to whether or not the person is going to work, not whether or not they use an alarm clock. --sciencewatcher (talk) 20:22, 14 April 2018 (UTC)

CFS/PTSD

Low CAR in chronic fatigue syndrome and PTSD needs to be added. --sciencewatcher (talk) 04:53, 29 April 2014 (UTC)
