What is the term used to describe when something exceeds someone's comfort level?

The correct term to describe when something exceeds someone's comfort level is "overexposure." This term is often used to indicate a situation where a person is subjected to something beyond their capacity to cope with or handle comfortably. In various contexts, such as in mental health, personal boundaries, or even in physical situations, overexposure signifies that an individual has been placed in an environment or situation that is overwhelming or distressing beyond their threshold of comfort.

In contrast, the other choices reflect different concepts. Overreaction generally refers to an emotional response that is disproportionate to the actual situation. Overindulgence implies excessive indulgence in something, which may lead to negative consequences but does not specifically address the idea of comfort levels. Overload indicates being overwhelmed with too much of something, but it typically refers to tasks or responsibilities rather than personal comfort zones. Therefore, "overexposure" captures the essence of exceeding a person's comfort level most accurately.
