Recent increases in XR headset sales suggest a growing consumer preference for AR/VR in home and institutional environments. As XR technology becomes mainstream and evolves, it is essential to examine its physical and mental impacts. While recent studies emphasize the positive effects of XR, this paper argues for investigating potential negative outcomes to ensure user well-being and ethical standards. This study involved young adults (ages 18–29) using the Apple Vision Pro headset within a visionOS environment, designed to encompass a range of user interactions. Questionnaires and health tests were conducted to evaluate participants. Findings indicate users’ adeptness in interacting with XR technologies, particularly favoring experiences that simulate real-life environments in three dimensions. However, despite their familiarity with technology and extensive screen time, young adults experienced physical side effects early in the testing process. This research underscores the necessity of a balanced understanding of XR’s implications to guide its development responsibly.
