The "red zone" typically refers to an area that is considered high-risk or dangerous. In various contexts, such as sports or health, it can indicate a critical situation that requires immediate attention. For example, in American football, the red zone is the area within 20 yards of the opponent's end zone, where scoring opportunities increase significantly. In the context of health, the red zone can refer to a stage in a person's health condition that requires urgent care or intervention. This term is often used in discussions about heart disease or emergency medicine, highlighting the importance of recognizing and responding to critical health issues promptly.
