A nurse is teaching a client who reports insomnia. Which of the following statements should the nurse make?

A. "Stop exercising at least 30 minutes before bedtime.": Vigorous exercise should be avoided within several hours of bedtime, not just 30 minutes, because it stimulates the body and can make falling asleep more difficult. B. "Take a 1 hr nap each day.": Long naps during the day can interfere with nighttime sleep by reducing sleep drive. If naps are needed, they should be brief (20–30 minutes) and earlier in the day. C. "Keep your bedroom at a warm temperature.": A cool, quiet, and dark environment promotes better sleep. Warm temperatures may cause restlessness and discomfort, making it harder to stay asleep. D. "Remove the television from your bedroom.": Removing stimulating activities such as watching TV or using electronics in bed promotes better sleep hygiene. The bedroom should be reserved for sleep and relaxation, which helps train the body to associate the space with rest.
