The purpose of this study was to describe nocturnal sleep and daytime nap duration in relation to salivary cortisol levels and child temperament in nonproblem nappers and problem nappers. Nighttime sleep and nap durations were obtained with continuous actigraph recordings for 3 days and nights (Tuesday, Wednesday, and Thursday) on 38 children aged 3 to 5 years who attended full-day child care centers. Nap times and disruptive behaviors were also observed and coded on each of the 3 days. Parents completed a temperament scale, sleep diaries, and the Children's Sleep Habits Questionnaire. Salivary cortisol samples were collected midmorning and in the afternoon after a nap on 2 consecutive days (Wednesday and Thursday). Problem napping and disruptive behaviors were associated with more negative affect, higher afternoon cortisol levels, and a smaller decrement in cortisol from morning to afternoon. Problem napping and disruptive behaviors were also associated with longer nighttime sleep, shorter nap durations, and later rise times. These data provide some insight into the associations among nighttime sleep, napping behavior, and salivary cortisol.

Cortisol awakening response (CAR) research relies upon self-collected saliva sampling during the post-awakening period. It is unknown how the CAR protocol is perceived and how they may affect typical routines relevant to CAR methodology. CAR assessment is sensitive to state variables, suggesting that CAR measurement may be affected by research participation.

There is a lack of objective indicators to evaluate the treatment effect of burning mouth syndrome, a neuropathic pain of unknown causes. Therefore, this study aimed to evaluate potential salivary biomarkers by analyzing saliva before and after clonazepam treatment in patients with burning mouth syndrome. Saliva was collected from 23 patients with burning mouth syndrome before and 4 weeks after the topical administration of clonazepam.

Background And Objectives: Laboratory-based stress inductions are commonly used to elicit acute stress but vary widely in their procedures and effectiveness. We compared the effects of stress induction techniques on measures of two major biological stress systems: the early sympathetic-adrenal-medullary (SAM) and the delayed hypothalamic-pituitary-adrenal (HPA) axis response.
Design: A review and meta-analysis to examine the relationship between stress induction techniques on cardiorespiratory and salivary measures of SAM and HPA system activity.

Adverse early-life experiences alter the regulation of major stress systems such as the hypothalamic-pituitary-adrenal (HPA) axis. Low early-life maternal care (MC) has repeatedly been related to blunted cortisol stress responses. Likewise, an acutely increased awareness of mortality (mortality salience [MS]) also has been shown to blunt cortisol responses.

Goals: To investigate whether basal and stimulated levels of cortisol differ between healthy people with obesity and individuals with normal weight Design: Total, free, and salivary cortisol were tested at baseline state and after 1 g ACTH stimulation in 60 healthy subjects with obesity and 54 healthy lean controls.
