• B. Sleep hygiene only matters for children.
• C. Adults should sleep 5-6 hours.
• D. Sleep duration is not related to health.

Answer: (A)

Sleep is a foundational component of health promotion because adequate rest supports physical health, mental well-being, and daily functioning. When you get enough sleep, mood, memory, and decision-making are clearer, immune function is stronger, and the body regulates appetite and metabolism more effectively. In adult health guidelines, the typical target is seven to nine hours of sleep per night for most adults, combined with a regular sleep schedule—same bedtime and wake time every day. A consistent routine and a sleep-friendly environment (cool, dark, quiet) help the body settle into a reliable rhythm. Limiting stimulants like caffeine later in the day, avoiding heavy meals before bed, and reducing screen exposure before sleep also improve sleep quality and make the target easier to reach. Prioritizing sleep within health promotion reduces risks for obesity, high blood pressure, type 2 diabetes, heart disease, mood disorders, and cognitive problems, while also enhancing daytime functioning and safety. Shorter or more irregular sleep can undermine these health benefits, and sleep does relate to physical and mental health, not just for children.
