Time flow of the experimental process. RS1 and RS2 correspond to the resting state periods, where participants had to rest with their eyes closed. First, the participants completed RS1. Then, they went through the Montreal imaging stress test (MIST) test. The MIST phase was common for both groups and it consisted of a test with the aim of stressing the subjects. The next phase corresponded to relaxation, where participants were split into two groups. The control group was conducted to relaxation using a chromotherapy room, while the test group used our virtual reality proposal. Finally, a second resting state period, RS2, was completed. During the experiment, the participants filled several surveys (T1–T4) to report their perceived stress level. The experiment lasted approximately 18 min.
