If your healthcare provider has recommended a sleep test, you may be wondering what to expect. A sleep test, also called a sleep study, is an important tool for diagnosing conditions like sleep apnea, restless legs syndrome, and other sleep disorders. Whether you’re completing an overnight study in a sleep center or using a home sleep testing device, a little preparation can help ensure the most accurate results.
Here are 4 tips to help you get ready for your sleep test.
Before your sleep test, you’ll receive specific instructions based on the type of study you’re having. If you’re taking a home sleep test, you’ll be shown how to wear the sensors correctly and when to start the recording. For an in-lab sleep study, you’ll be told when to arrive and what to bring.
Be sure to ask questions if anything is unclear. Properly placing sensors and following the instructions helps ensure the equipment collects accurate information about your breathing, heart rate, oxygen levels, and sleep patterns.
If you’re asked to continue taking your regular medications, do so unless your healthcare provider tells you otherwise.
Caffeine and alcohol can interfere with your normal sleep patterns, which may affect your test results. On the day of your sleep study, it’s generally best to avoid coffee, energy drinks, soda, chocolate, and other sources of caffeine during the afternoon and evening.
Alcohol should also be avoided before your test. While it may make you feel sleepy initially, it can disrupt your sleep cycle and affect your breathing during the night. Your goal is to sleep as naturally as possible so the study accurately reflects your typical sleep habits.
It may be tempting to take an extra nap or stay up late the night before your test, but it’s usually better to maintain your regular schedule. Wake up at your usual time, eat your normal meals, and follow your typical evening routine.
Before leaving for your appointment, take a shower and avoid using lotions, oils, hairsprays, or styling products. Clean, dry skin helps the monitoring sensors adhere properly throughout the night.
If you’re having an overnight study at a sleep center, bring comfortable pajamas, your toothbrush, and any other personal items you normally use before bed to help you feel more relaxed.
Many people are concerned they won’t be able to sleep while connected to monitoring equipment. Fortunately, sleep specialists understand that sleeping in a new environment can feel different. Even if you don’t sleep as deeply or as long as you normally do, the study often provides enough information to make an accurate diagnosis.
The equipment is designed to record valuable data throughout the night, and the sleep technologists will do everything they can to make you as comfortable as possible.
A sleep test is a safe, noninvasive way to identify the cause of persistent snoring, daytime fatigue, interrupted sleep, and other symptoms of sleep disorders. By following your provider’s instructions, avoiding caffeine and alcohol, maintaining your normal routine, and arriving prepared, you’ll help ensure the most accurate results.
