Which of the following is an effective intervention to promote sleep in older adults?

Maintaining a consistent sleep schedule is an effective intervention to promote sleep in older adults because it helps regulate the body's internal clock, known as the circadian rhythm. This regulation is crucial in ensuring that the individual feels sleepy at appropriate times and can enhance the quality of sleep. Consistency in sleep timing can lead to improved sleep quality, making it easier for older adults to fall asleep and stay asleep through the night. Having a stable routine signals the body when it’s time to wind down and prepare for sleep, which can be especially beneficial for older adults who often experience disruptions in sleep patterns.

In contrast, avoiding physical activity is not suitable, as engaging in regular light exercise can actually promote better sleep quality and help relieve insomnia. Consuming large meals before bedtime can disrupt sleep, as it may lead to discomfort or indigestion that interferes with the ability to fall asleep. Reducing water intake might seem like it could prevent nighttime awakenings, but adequate hydration is important for overall health, and restricting intake can lead to dehydration or other health issues.
