The term "extreme conditions" refers to situations or circumstances that are characterized by a high degree of intensity, severity, or harshness. These conditions can be physical, such as extreme heat or cold, hurricane-force winds, or blizzard conditions; or they can be emotional, such as intense fear, anxiety, or stress. In any case, "extreme" implies a level of intensity that is beyond what is typically experienced in everyday life and may require specialized knowledge, skills, or equipment to manage safely.
