Brief Summary

Although exposure to nature has restorative effects on human health, beneficial effects of nature-based interventions in the working environment have been underexplored. The investigators aim to conduct a randomised controlled pilot study. During workhours one group participates in a nature-based program, the other group is a control group. The investigators test stress-related parameters including cortisol levels, wellbeing and stress, and neurocognition.

Outcome Measures

Primary Outcomes (7)

  • Neurocognition: selective attention

    computerised tests (stroop test). The scale is mean reaction time and is used as a continuous variable.

    5 minutes

  • Neurocognition: short-term memory

    computerised tests (Digit Span Test). The scale is number of digits and is used as a continuous variable.

    10 minutes

  • Neurocognition:visual information processing speed

    computerised tests (Digit Symbol test). The scale is number of digits and is used as a continuous variable.

    5 minutes

  • Neurocognition: visual information processing speed

    computerised tests (Pattern Comparison test ). The scale is reaction time and is used as a continuous variable.

    5 minutes

  • stress levels

    Assessed by salivary cortisol levels. Scale is µg/dl and used as a continuous variable.

    5 minutes

  • stress levels

    Assessed by questionnaires (burnout assessment tool). Scores are used as continuous variable. Lower scores represent lower risk of burnout, higher scores represent higher risk of burnout. The score is constructed from questions concerning exhaustion, mental distance, emotional disorder and cognitive disorder.

    10 minutes

  • stress levels

    Assessed by smartwatch (algorithm including hart rate and movement). Values are used as continuous variable

    3 weeks
