What is the impact of sleep hygiene on stress?

• A. Good sleep hygiene worsens stress due to insomnia rebound.
• B. Sleep quality is unaffected by stress levels.
• C. Good sleep hygiene improves sleep quality and reduces perceived stress; poor sleep worsens stress and mood.
• D. Sleep hygiene only affects physical recovery, not mood or stress.

Answer: (C)

Quality sleep supports emotional regulation and how we handle stress. When you follow good sleep hygiene—consistent bed and wake times, a comfortable sleep environment, limiting caffeine and evening screens—you get more restorative sleep. With better sleep, the brain’s ability to cope with daily stress improves and mood stays steadier, so perceived stress tends to decrease. Conversely, poor sleep leaves you more irritable, exhausted, and reactive to stress, which can worsen mood and create a cycle of higher stress. That’s why the statement that good sleep hygiene improves sleep quality and reduces perceived stress, while poor sleep worsens stress and mood, best fits what happens. The other options don’t fit because sleep quality is linked to stress, sleep isn’t only about physical recovery, and good sleep hygiene does not worsen stress.
