You can visually measure stress and relaxation. It is more objective and
reproducible, compared to typical medical interview-based self-assessment. Combining the relaxation assessment and skin measurement,
we can evaluate the improvement effect of the skin condition due to mental stress.
Before and after evaluation, blood flow in some brain regions is measured using near-infrared light. It is said that when relaxed, the blood flow in the front right section decreases.
We measure the pupil size contraction(miotic pupil rate) before and after evaluation. When relaxed, miotic pupil rate increases.
We monitor and quantify changes in blood flow at the fingertip before and after evaluation. When relaxed, blood flow at the fingertip increases.
