OBJECTIVE Despite their high prevalence in daily life, repeated night-wakings and their cognitive and emotional consequences have received less research attention compared to other types of sleep disturbances. Our aim was to experimentally compare the effects of one night of induced infrequent night-wakings (of ∼15 min, each requiring a purposeful response) and sleep restriction on sustained at...

BACKGROUND The diversity of pharmacological actions of antidepressants suggests that they may bring about their clinical effects by different functional means. METHODS Twenty healthy volunteers were randomized in a cross-over design to receive 2 weeks of a clinical dose of both reboxetine and sertraline. Baseline assessments of personality were made using the Cloninger Tridimensional Personal...

Recent progress with wearable sensors has enabled researchers to capture face-to-face interactions quantitatively and given great insight into human dynamics. One attractive field for applying such sensors is the workplace, where the relationship between the face-to-face behaviors of employees and the productivity of the organization has been investigated. One interesting result of previous stu...

UNLABELLED MDMA induces positive mood and increases impulse control during intoxication, but only a few studies on the neuropharmacological mechanisms underlying these processes have been conducted. It was hypothesized that pretreatment with 5-HT(1) and 5-HT(2) receptor blockers would prevent MDMA effects on mood and impulsivity. Subjects (N = 17) participated in a double-blind, placebo control...

Walnuts contain a number of potentially neuroprotective compounds like vitamin E, folate, melatonin, several antioxidative polyphenols and significant amounts of ω-3 fatty acids. The present study sought to determine the effect of walnuts on mood in healthy volunteers. Sixty-four college students were randomly assigned to two treatment sequences in a crossover fashion: walnut-placebo or placebo...

OBJECTIVE This study explored whether drinking tea "treated" with good intentions would enhance mood more than drinking ordinary tea, under double-blind, randomized conditions. DESIGN Each evening, for seven days in a row, volunteers recorded their mood using the Profile of Mood States (POMS) questionnaire. On days three, four, and five of the test, each participant drank 600 mL of oolong tea...

To investigate the impact of overtime work, sleep duration, and perceived job characteristics on physical and mental status, a cross-sectional study was conducted on 377 workers (average age; 28 years old) in an information-technology (IT) company, engaged in consultation, system integration solution, and data management relevant to IT system. The psychophysical outcomes of overtime work were a...

Abstract Background An increasing number of gastrointestinal cancer (GI) patients suffer from side effects treatment that can affect their mood states and quality life. Despite its demonstrated effectiveness in female patients, Supportive Expressive Group Therapy (SEGT) has not been tested male patients. The current study sought to examine the longitudinal a professionally-led, men-only SEGT on...

The purpose of this study was to evaluate the effectiveness of a group intervention approach aimed at improving the mental health of psychiatric nurses exposed to violent speech/violence. Sixty-two nurses having experienced serious episodes of violent speech/violence were enrolled in this study. A group intervention approach was used in the intervention group. For both the intervention and the ...

Time spent walking and relaxing in a forest environment ("forest bathing" or "forest therapy") has well demonstrated anti-stress effects in healthy adults, but benefits for ill or at-risk populations have not been reported. The present study assessed the physiological and psychological effects of forest therapy (relaxation and stress management activity in the forest) on middle-aged males with ...
