Which term refers to physical conditions that impact sleep quality?

• A. Physiological Factors
• B. Sleep Environment
• C. Stress Incontinence
• D. Sleep Strategies

Answer: (A)

Physical conditions that affect sleep quality are described as physiological factors. This term covers body-based processes and health problems that can interrupt or fragment sleep, such as chronic pain, heart or lung disease, nocturnal urine production, sleep-disordered breathing, restless legs syndrome, and how medications or aging alter sleep regulation. Distinguish these from the sleep environment, which refers to external factors like noise, light, and temperature, and from sleep strategies, which are techniques used to improve sleep. For example, arthritis pain or nighttime urinary frequency disrupt sleep due to physiological factors. While conditions like stress incontinence can contribute to sleep disruption, the broader category describing all body-related factors affecting sleep is physiological factors.
