A "content warning" is a notice that alerts individuals about potentially distressing material in a piece of media, such as a book, film, or online post. These warnings help prepare audiences for themes that may include violence, trauma, or other sensitive topics, allowing them to make informed choices about their exposure to the content. Content warnings are often used in various settings, including social media, educational materials, and mental health resources. They aim to create a safer environment for individuals who may have personal experiences related to the content, promoting awareness and sensitivity in discussions around difficult subjects.
