What should the nurse instruct a client to avoid before bedtime to help with sleep difficulties?

Avoiding colas, teas, and coffee before bedtime is crucial for individuals experiencing sleep difficulties. These beverages contain caffeine, a stimulant that can interfere with the ability to fall asleep or stay asleep throughout the night. Caffeine can remain in the system for several hours, and its stimulating effects may make it harder for the brain to relax and enter the sleep cycle. By eliminating or minimizing the consumption of these items in the evening, clients can create a more conducive environment for restful sleep, allowing for better overall health and well-being.

In the context of sleep hygiene, while avoiding sugary snacks, heavy meals, and loud noises can also be beneficial, the impact of caffeine on sleep quality is particularly significant and well-documented.
