abstract = {Chromotherapy rooms are comfortable spaces, used in places like special needs schools,
where stimuli are carefully selected to cope with stress. However, these rooms are expensive and
require a space that cannot be reutilized. In this article, we propose the use of virtual reality (VR)
as an inexpensive and portable alternative to chromotherapy rooms for stress relief. We recreated
a chromotherapy room stress relief program using a commercial head mounted display (HD).
We assessed the stress level of two groups (test and control) through an EEG biomarker, the relative
gamma, while they experienced a relaxation session. First, participants were stressed using the
Montreal imaging stress task (MIST). Then, for relaxing, the control group utilized a chromotherapy
room while the test group used virtual reality. We performed a hypothesis test to compare the selfperceived
stress level at di erent stages of the experiment and it yielded no significant di erences
in reducing stress for both groups, during relaxing (p-value: 0.8379,   = 0.05) or any other block.
Furthermore, according to participant surveys, the use of virtual reality was deemed immersive,
comfortable and pleasant (3.9 out of 5). Our preliminary results validate our approach as an
inexpensive and portable alternative to chromotherapy rooms for stress relief.},
