Which category does sleep deprivation belong to in crisis contributors?

• A. Mental health symptom
• B. Substance misuse/misuse
• C. Physical external condition
• D. Situational stressor

Answer: (C)

Sleep deprivation is a physical external condition because it describes a physiological state of the body—missing sufficient sleep—that directly affects how a person thinks, feels, and behaves. It’s a bodily condition, not a mental health symptom, not a substance misuse issue, and not a standalone situational stressor. While stress, illness, or environment can lead to sleep loss, the condition itself resides in the body’s state rather than in thoughts, substances, or a discrete stressful event. Recognizing it as a physical external condition helps explain its impact on functioning and why it’s considered a contributing physical factor in a crisis.
