Whenever a pupil dilates from stress, it practically is showing effects of the fight or flight reaction. There are multiple factors that lead to this but that is the main reason.

The sympathetic branch of the ANS responds to a person being under stress, triggering the “fight or flight” response, which will cause the pupil to dilate.
