Shiftworkers frequently experience sleep loss (<6 hrs. following nightshift), due to the circadian misalignment resulting from the sleep-wake patterns of their roster cycle. Within a mining operation, this sleep loss may have significant consequences due to fatigue, including an increased risk of accidents and chronic health conditions. This study...

Twelve female players and three male coaches wore actigraphy devices for 60 nights during the Women's National Basketball League, Australia, to assess sleep and alertness and completed questi...
Article
Anecdotal reports suggest that the first night of sleep monitoring using a wrist‐actigraphy monitor may result in impaired sleep when compared to subsequent nights, due to increased levels of anxiety and awareness of being monitored. This phenomenon has been seen in sleep laboratories with polysomnographic monitoring. However, this is yet to be est...

Novel methods of acute weight loss practiced by combat sport athletes include 'water loading'; the consumption of large fluid volumes for several days prior to restriction. We examined claims this technique increases total body water losses, while also assessing the risk of hyponatremia. Male athletes were separated into control (CON, n=10) and wat...

Accurate measurement of time at lights out is essential for calculation of several measures of sleep in wrist-activity monitors. While some devices use subjective reporting of time of lights out from a sleep diary, others utilise an automated proprietary scoring algorithm to calculate time at lights out, thereby negating the need for a sleep diary....

Background: Wrist-activity monitors (WAM) are used to objectively assess ‘sleep’ in shift-workers. Accurate measurement of time at ‘lights out’ (LO) is essential for calculation of several activity-derived measures including sleep latency (SL), sleep duration (SD), wake after sleep onset (WASO) and sleep efficiency (SE). Some devices use subjective...

Question
Hi all,
Does anyone have any good presentations, examples or suggested reading on how to explain the two process model for Sleep/Wake ? S -Sleep and C-Circadian. The original research paper by Daan,Beersma and Borbely 1984 can be a little confusing. 
Cheers

Question
Hi,
Does anyone know of any modelling tools or methods to model caffeine?,in particular its to apply restrocpectively to a data set. It was during a rugby game with caffeine saliva samples taken 2 hrs before the game and within 1 hr of the game. I have individual bodyweight for 20 people and self reported caffeine. I am trying to use a predictive model/technique to ascertain peak caffeine level and the half life of caffeine. I have the time of sleep onset and the sleep latency for each individual. The timw at sleep onset is roughly 4-5 hrs after the post game caffeine levels.
Any thoughts,models or methods ?
Cheers

Good day all ,
Has anyone conducted or does anyone know of any studies that have validated popular wearable technologies such as jawbone,fitbit etc against PSG (Kripke method) or any method. In particular for performance or industrial settings.
