What are common patient instructions before a sleep study?

It is essential for patients to avoid caffeine, alcohol, and excessive napping prior to a sleep study because these substances and activities can significantly interfere with the quality of sleep that is evaluated during the study. Caffeine, a stimulant, can disrupt the natural sleep cycle and make it harder to fall asleep. Alcohol, while often initially sedating, can lead to fragmented sleep and reduce the overall quality of sleep. Excessive napping during the day can also impact the ability to fall asleep naturally at night due to increased daytime sleepiness and altered sleep patterns.

By following these instructions, patients can ensure that the results of the sleep study more accurately reflect their typical sleep patterns and behaviors, allowing for more effective diagnosis and treatment planning.
