Which statement best describes the effect of daily exercise on sleep for someone aiming to lose weight?

• A. Exercise daily can help reduce bedtime wakefulness
• B. Exercise at night increases wakefulness
• C. Exercise has no effect on sleep
• D. Exercise worsens sleep quality

Answer: (A)

Regular daily exercise tends to improve sleep quality by helping you fall asleep more quickly and stay asleep with fewer awakenings. When sleep is more continuous and restorative, it supports weight loss by boosting recovery, daytime energy, and adherence to activity and eating plans. That makes the statement about daily exercise reducing bedtime wakefulness the best description: you’re more likely to experience fewer interruptions at night, which contributes to better overall sleep and supports weight loss goals. While very late or intense workouts can affect individuals differently, the overall pattern is that regular activity enhances sleep continuity, rather than worsening it.
