Short Vacation Improves Stress-Level and Well-Being in German-Speaking Middle-Managers-A Randomized Controlled Trial.

Stress in the work place has a detrimental effect on people's health. Sufficient recovery is necessary to counteract severe chronic negative load reactions. Previous research has shown that vacationing for at least seven consecutive days provided an efficient recovery strategy. Yet, thus far, the effects of short vacations and the mode of vacation (whether at home or in a new environment) have rarely been studied. We investigated the immediate and long-term effects of a short vacation (four nights) on well-being and perceived stress and whether the mode of vacation impacted on these results. Data was obtained from 40 middle managers (67.5% men and 32.5% women). The intervention group (n = 20) spent a short vacation in a hotel outside their usual environment. The control group (n = 20) spent their vacation at home. Results indicated that one single short-term vacation, independent of the mode, has large, positive and immediate effects on perceived stress, recovery, strain, and well-being. Strain levels decreased to a greater extent in the intervention group compared to the control group. The effects can still be detected at 30 days (recovery) and 45 days (well-being and strain) post-vacation. Encouraging middle management employees to take short vacations seems to be an efficient health promotion strategy; environmental effects seem to play a minor role.

Intense illumination in the morning hours improved mood and alertness but not mental performance.

Cognitive performance and alertness are two determinants for work efficiency, varying throughout the day and depending on bright light. We conducted a prospective crossover study evaluating the impacts of exposure to an intense, early morning illumination on sustained attention, alertness, mood, and serum melatonin levels in 33 healthy individuals. Compared with a dim illumination, the intense illumination negatively impacted performance requiring sustained attention; however, it positively impacted subjective alertness and mood and had no impact on serum melatonin levels. These results suggest that brief exposure to bright light in the morning hours can improve subjective measures of mood and alertness, but can also have detrimental effects on mental performance as a result of visual distraction. Therefore, it is important that adequate lighting should correspond to both non-visual and visual demands.

Short-term effects of bright light therapy in adults with chronic nonspecific back pain: a randomized controlled trial.

OBJECTIVE: The present trial evaluated incorporation of bright light therapy in the treatment of chronic nonspecific back pain (CNBP). DESIGN: A prospective, randomized, controlled, multicenter, open design with three parallel trial arms was used. SETTING: Subjects received a novel therapeutic, an expected therapeutic ineffective low dose, or no light exposure at three different medical centers. PATIENTS: A total of 125 CNBP patients reporting pain intensity of ≥3 points on item 5 of the Brief Pain Inventory (BPI) were included. INTERVENTION: Over 3 weeks, 36 active treatment, 36 placebo controls, and 33 controls received 3 or no supplementary light exposures of 5.000 lx or 230 lx, respectively. OUTCOME MEASURES: Changes in self-reported scores of pain intensity (BPI sub-score 1) and depression (Hospital Anxiety and Depression Questionnaire) were the primary outcome measures. Secondary outcome measures were changes in self-reported overall pain sensation (BPI total score), grade of everyday life impairment (BPI sub-score 2), mood (visual analog scale), and well-being (World Health Organization-Five Well-Being Index). RESULTS: Changes in pain intensity were higher (1.0 [0.8-1.6]) in the bright light group compared with controls (0.3 [-0.1-0.8]; effect size D = 0.46). Changes in the depression score were also higher in the intervention group (1.5 [0.0-2.5]) compared with controls (0.0 [0.0-2.0]; effect size D = 0.86). No differences were seen in change scores between intervention vs sham group. CONCLUSION: The present randomized controlled trial shows that light therapy even in low dose could improve depressive symptoms and reduce pain intensity in CNBP patients. Further research is needed for optimizing parameters of frequency, dose, and duration of therapeutic light exposure.

Evaluation of West-Austrian junior athletes' knowledge regarding doping in sports.

BACKGROUND: An important factor while developing efficient doping prevention strategies is to identify relevant target groups, to evaluate the state of knowledge about this topic as well as to evaluate motivations behind using prohibited substances. Measures to prevent doping substances abuse have to be supported in early stages of childhood. PURPOSE: The aim of this prospective study was to evaluate the knowledge of Tyrolean junior athletes about doping in sport. Next to the knowledge, their attitudes in regard to doping practices have also been a focus of this project. METHODS: Within a prospective cross-sectional study, Tyrolean junior athletes aged between 14 and 19 years (n = 408) were anonymously questioned by distributing questionnaires in three Tyrolean sport schools as well as two Tyrolean sport-training centers. To collect the data, an anonymous questionnaire with close-ended questions was used. Next to sociodemographic data, questions also evaluated the knowledge about prohibited substances as well as attitudes and behaviors towards doping. The concept was set up based on contents of comparable studies and publications. RESULTS: The knowledge about doping among junior athletes was moderate. The consumer behavior of the young athletes on the other hand has turned out to be satisfactory. Nevertheless, the overall knowledge especially regarding potential negative side effects of doping agents is poor. CONCLUSIONS: To incorporate an effective doping-prevention strategy, improved education, particularly in terms of side effects, is clearly needed. To achieve sustainable doping-prevention effects, focus has to be generally set on education within the frame of junior competitive sport.
