Which term describes physical factors that affect sleep quality?

• A. Sleep Strategies
• B. Sleep Environment
• C. Physiological Factors
• D. Age-Related Changes

Answer: (C)

Sleep quality is shaped by what the body does and how its systems function—that's physiological factors. These include hormonal cycles and circadian rhythm, medical conditions, pain, nocturia, and the effects of medications, all of which can make it harder to fall asleep or stay asleep and can alter how deeply one sleeps. The question targets this internal, body-based influence, which is why physiological factors is the best label. By contrast, the sleep environment refers to room conditions like light and noise, sleep strategies are behavioral routines, and age-related changes describe general aging processes, not the specific internal processes that disrupt sleep.
