Filter by:Vitamin C (ascorbic acid) is a well-known antioxidant that is involved in anxiety, stress, depression, fatigue and mood state in humans . The purpose of this study is to investigate the effect of low doses of vitamin C on decreasing the level of public speaking stress in term of salivary cortisol , blood pressure (systolic and diastolic) and heart rate . A purposive sample of (90) were included in this randomized placeboled trial study (60 students were given 500 mg of vitamin c per day for one week a group presentation while 30 other students were given placebo for one week before a group presentation) . Salivary cortisol was measured by means of commercial immunoenzymatic kits . Blood pressure (systolic and diastolic) and heart rate were measured immediately before and after presentation .
Everyday life psychosocial challenges may negatively impact health and well-being, contributing to the onset and/or progression of psychological and psychosomatic disorders. Pharmacological treatments can moderate our stress response, but they usually bring about addiction/tolerance and a number of other side effects. Therefore, it is relevant to identify alternative stress relief strategies that are devoid of these unwanted drawbacks. Moreover, the effects of such alternative interventions should be objectively quantified by means of reliable psychobiological parameters. The goal of this study was to quantify the acute and persistent effects of a cosmetic routine based on the self-administration of a cream enriched with essential oils, namely Juniperus Phoenicea gum extract, Copaifera Officinalis resin, Aniba Rosodora wood oil, and Juniperus Virginiana. This aim was achieved by measuring the (re-)activity of the autonomic nervous system (via heart variability indexes) and the hypothalamic-pituitary-adrenocortical axis (via salivary cortisol levels), as well as through psychometric and behavioral assessments. Participants' informed consent signature for adhesion at the study was initially requested. With their acceptance, parameters were recorded anonimously, identified by their initials and an alphanumeric code. Data were transferred on Excel worksheets, utilized for descriptive analysis related at every variable. All statistical analyses were performed using SPSS 25 software package and statistical significance was set at p<0.05.
The purpose of this clinical trial is to determine whether Probiotic can modulate the psychological stress experienced by healthy medical, dental and health science students preparing for university/institute of technology semester examination (s), measured by self-report scales and hypothalamic pituitary adrenal axis activity, compared with placebo.
A convenient sample of internal medicine residents will be observed during their nightshift work in the wards of the department of internal medicine of a university hospital. The epidemiology of night calls and emergencies, including incidence, causes, management, and prognosis, will be assessed prospectively. The impact of nightshift work on sleep, stress, quality of life, regrets, and general well being of the residents observed will be measured through completion of validated questionnaires. Quality of handoff sessions will also be assessed.
The investigators plan to conduct a crossover experimental trial examining physiological responses to a socio-evaluative speech task under laboratory conditions. Participants will attend two laboratory sessions. At one session participants will take part in a brief laboratory stress task and at the other participants will rest for the same period. Measures of cardiovascular response will be assessed at both sessions. In addition, blood will be drawn at multiple time points across a 125 minute period to assess changes in circulating levels of cortisol, catecholamines, markers of inflammation and cell free mitochondrial DNA in response to the task. The investigators expect that the stress task will induce a specific increase in ccf-mtDNA, which will statistically mediate subsequent peak circulating Interleukin-6 and Tumor Necrosis Factor-α levels. In secondary analyses, the investigators will examine whether stress-induced increases in circulating cortisol, epinephrine, and norepinephrine levels correlate with increases in ccf-mtDNA. These studies will establish the kinetics and magnitude of psychological stress-induced ccf-mtDNA release, the association with early stress mediators, and whether ccf-mtDNA mediates the inflammatory response to acute stress in humans.
The purpose of this acute randomized control study is to assess the feasibility of a low-to-moderate intensity Yoga intervention (i.e. sun salutations), and examine its effect on cognitive functioning, compared to engaging in aerobic activity or seated rest. Participants will include individuals who are currently experiencing symptoms of psychosocial stress or general anxiety.
The primary aim of this study is to assess the feasibility of an intervention to reduce and break up prolonged sitting time in full-time police staff. The secondary aims of this study are to assess preliminary effects on patterns of sedentary behaviour (number of breaks, number of prolonged sitting bouts, average duration of prolonged sitting bouts, and total prolonged sitting duration), additional measures of sedentary behaviour (total sitting time, standing, and stepping), cardiometabolic risk markers, physiological stress (cortisol levels), physical health (self-report and postural stability), psychological wellbeing and mood, work stress (self-reported), and work performance (job satisfaction and productivity).
This project aims to determine whether neurofeedback augmented mindfulness intervention increases the plasticity in brain areas affected by exposure to early life adversity in youth. The study will first establish the augmented mindfulness training protocol targeting the posterior cingulate cortex (PCC) with real-time fMRI neurofeedback for use with healthy control and ELA-exposed youth. Next, in addition to ongoing data collection with healthy controls, ELA-exposed youth will be randomly assigned to either complete the neurofeedback augmented mindfulness training (AMT) or sham condition protocol. Effect of augmented mindfulness training on state measures of mindfulness, perceived stress, and affect will be examined.
The aim of this study is to measure the effects of three stress reduction methods on patients with stress and stress associated complaints.
The goal of this study is to develop and pilot test a telehealth behavioral weight control intervention for adolescents from a low-income background that combines facets of mindfulness training with behavioral weight control. We aim to examine biological (e.g., weight) and behavioral (e.g., emotional eating, mindfulness) changes as a result of a 12-session mindfulness-based weight control intervention compared to a 12-session standard behavioral weight control intervention.
