Sensitive parenting early in life sets children up for healthy development, and this type of parenting draws on the parent's compassion and physiological regulation. Loving-kindness meditations (LKM) increase compassion and reduce physiological responses to stressors and so may support sensitive parenting. The current study tested the effects of a LKM on parent sensitivity and salivary alpha amylase (sAA) during a parent-child interaction. One hundred and thirty-six parents (114 mothers, 22 fathers) of toddlers (18-36 months, M = 28.85 months, SD = 5.13) participated in an online survey and were randomly assigned to listen to either a LKM, focused-imagery audio, or podcast during a video call before engaging in a play-based interaction with their toddler. Parent sAA was collected from parents at five points throughout the video call. LKM did not significantly increase parent sensitivity (B = 0.06, p = 0.86); however, there was limited variability in sensitivity in this sample (M = 6.01, SD = 0.89). The LKM did affect sAA activity (B = - 0.66, p < 0.05) such that parents in the LKM group gradually decreased sympathetic activity across the research session, whereas the podcast group increased sAA levels after the parent-child interaction. Overall, these findings suggest that engaging in compassion and self-compassion can change the pattern of stress physiology in parents of toddlers while parenting.

Background: Eating disorders such as Anorexia Nervosa (AN) and Bulimia Nervosa (BN) were previously found to partly entail alterations in stress physiology including salivary cortisol (sC), and salivary alpha amylase (sAA) at rest and basal vagal tone (HF-HRV), compared to individuals without mental disorders or with mixed mental disorders (anxiety and depressive disorders), but corresponding data remain scarce and are not entirely consistent.
Method: HF-HRV, sC and sAA at rest were assessed in a female sample of 58 individuals with AN and 54 individuals with BN before and after psychotherapy and contrasted against measurements from 59 female individuals suffering from mixed disorders and 101female healthy controls.
Results: Values for sC were elevated in AN compared to all other groups, those for HF-HRV were highest in both AN and BN and lowest in mixed mental disorders and no differences were found at rest for sAA.

Light serves as the main synchroniser of the circadian system. The amount of light and its spectral distribution throughout the day influence hormonal secretion and sleep-wake regulation. There is a knowledge gap regarding the impact of the spectrum and intensity reduction of short-wavelength light during the day on circadian system outputs.

Introduction: Poor quality of life and psychological stress have been associated with worse clinical outcomes, including anxiety and depression disorders, cardiovascular diseases, metabolic syndrome, type 2 diabetes, and premature mortality. Evidence suggested that physically active adults were more likely to report better quality of life and increased capacity to deal with stress, compared to their sedentary peers. This study examines the effects of 16 weeks of combined aerobic and resistance exercise training on health-related quality of life (HRQoL) and stress levels in sedentary adults.

Background And Aim: There is a lack of research on the stress-related transfer from goal-directed behavior to stimulus-response habits in (early stages of) online buying-shopping disorder (BSD). This study investigated the Pavlovian-to-instrumental transfer (PIT) effect after reward devaluation (PIT-dev) as indicator of habitual behavior and its modulation by acute stress in individuals with risky (online) buying-shopping (r-BSh).
Methods: Individuals with r-BSh (n = 67) and a control group (n = 67) underwent a PIT paradigm with devaluation procedure.

Objective: Cortisol is a well-established biomarker of stress, assessed through salivary or blood samples, which are intrusive and time-consuming. Speech, influenced by physiological stress responses, offers a promising non-invasive, real-time alternative for stress detection. This study examined relationships between speech features, state anger, and salivary cortisol using a validated stress-induction paradigm.
