Interventions
Participants will be randomly assigned to either the treatment (virtual reality, VR) or the active control group (freely chosen relaxation method) according to an externally constructed randomization
during the relaxation phase, sunrise is simulated. Via headphones calming music and nature sounds will be presented to the participants. During the relaxation phase, participants will be seated on a c

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1. Stress ratings measured with a visual analogue scale (VAS) on a Likert scale ranging from 0 (not stressed) to 9 (very stressed) at pre-baseline, post-baseline, pre-stress, mid stress, post-stress, pre-relaxation, post-relaxation, pre-recovery, post-recovery and in the evening of the day of laboratory testing 2. Relaxation ratings will be measured with a VAS on a Likert scale ranging from 0 (not relaxed) to 9 (very relaxed) at pre-baseline, post-baseline, pre-stress, mid stress, post-stress, pre-relaxation, post-relaxation, pre-recovery, post-recovery and in the evening of the day of laboratory testing | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Heart rate variability measured with an electrocardiogram, analyzed using the Pan Tompkins algorithm, and estimated with the root mean square of successive differences (RMSSD) throughout baseline, stress, relaxation, and recovery 2. Tonic skin conductance level measured using galvanic skin conductance (GSR) recording and analyzed using Ledalab throughout baseline, stress, relaxation, and recovery 3. Number of phasic non-specific skin conductance responses measured using GSR recording and analyzed using Ledalab throughout baseline, stress, relaxation, and recovery 4 Systolic and diastolic blood pressure measured using an automated oscillometric blood pressure monitor at 1 min from the end of the baseline, stress, relaxation, and recovery phases 5. Respiratory rate measured using a respiration belt throughout baseline, stress, relaxation, and recovery 6. State mood measured using Der Mehrdimensionale Befindlichkeitsfragebogen (MDBF) questionnaire at pre-stress, post-stress, post-relaxation, and in the evening of the day of laboratory testing 7. State rumination measured using Der Response Styles Questionnaire (RSQ-D, adapted for state) at pre-stress, post-stress, post-relaxation, and in the evening of the day of laboratory testing 8. Post-event processing measured using Post-Event Processing Record (PEPR) questionnaire (translated to German) at post-relaxation and in the evening of the day of laboratory testing | — |
