Preparing for narcolepsy sleep study checklist

Undergoing a narcolepsy sleep study (often including an overnight polysomnogram followed by a Multiple Sleep Latency Test, or MSLT) can feel like a big step. Having a clear “Preparing for narcolepsy sleep study checklist” can help you arrive confident and ready, so your care team gets the most accurate information. Below is a straightforward guide—no sugar-coating, but also no unnecessary stress.

1. Understand what will happen

Before diving into what to bring and do, it helps to know the basic flow:

• Overnight polysomnogram (PSG): You sleep in a lab while sensors monitor brain waves, breathing, heart rate and movement.
• Multiple Sleep Latency Test (MSLT): The next day you take 4–5 scheduled naps to measure how quickly you fall asleep and enter REM sleep.

Talking through these steps with your sleep specialist or technologist in advance helps you feel more prepared.

2. Two weeks before your study

Adjusting habits in the days leading up can improve test accuracy.

• Keep a sleep diary for at least 7–14 days. Note bedtimes, wake times, naps, caffeine, alcohol and medication.
• Follow your usual sleep schedule—avoid drastic changes in bedtime or wake-up time.
• Limit or stop these substances, if possible:
  • Caffeine (coffee, tea, soda, energy drinks)
  • Alcohol
  • Nicotine
• Ask your doctor if any medications (especially stimulants, antidepressants or sleep aids) should be tapered or paused. Do not stop prescribed meds on your own.

3. The night before

A few simple steps the evening before help ensure clear results:

• Eat a light dinner. Heavy, fatty or spicy meals can cause discomfort overnight.
• Shower and shampoo. Sensors attach to clean, oil-free skin and hair. Avoid conditioner or heavy hair products.
• Skip caffeine after noon. Even green tea or chocolate can linger in your system.
• Pack your bag. See Section 5 below for a complete list.

4. Day of the study

On the morning of your study, maintain normal routines as much as possible:

• Get up at your usual time. A consistent wake-up helps the lab calibrate baseline sleepiness.
• Have a light breakfast. Oatmeal, toast or yogurt are good options—avoid greasy or heavy foods.
• Dress comfortably. Wear loose-fitting, two-piece sleepwear (shirt and pants) so you can easily attach electrodes.
• Limit liquids. Drink enough to stay hydrated, but don’t overdo it—you may need to minimize bathroom trips overnight.

5. What to bring

Pack a small overnight bag that includes:

• Comfort items:
  • Two-piece pajamas or loose shorts and a T-shirt
  • Socks and slippers or flip-flops
  • Eyemask and earplugs (if you normally use them)
• Personal care:
  • Toothbrush, toothpaste and hairbrush
  • Deodorant (unscented)
  • Lip balm (unscented)
• Entertainment & essentials:
  • Phone, charger and headphones
  • Book, tablet or quiet hobby (you’ll have waits between naps)
  • Eyeglasses or contact-lens case and solution
• Documentation:
  • Photo ID and insurance card
  • Sleep diary or log
  • List of current medications and doses
• Snacks and meals:
  • Light, easy-to-digest snacks (fruit, granola bars)
  • Lunch or money for on-site cafeteria

6. What to avoid

To get the clearest test results, steer clear of:

• Heavy meals right before bedtime
• Vigorous exercise within 3–4 hours of the study
• Nicotine, caffeine or alcohol
• New sleep aids or herbal supplements (unless cleared by your doctor)

7. During the study

Once you’re in the lab:

• Ask questions. It’s normal to be curious about equipment, electrodes and what you’ll experience.
• Be honest about sleepiness. The technologist needs accurate feedback on how you feel.
• Relax as much as possible. Even if it feels odd, try to treat it as your normal bedtime setting.

After the overnight portion, you’ll transition to the MSLT:

• You’ll lie down in a darkened room for 4–5 “nap sessions,” each 20 minutes long, scheduled two hours apart.
• A technologist will wake you after 20 minutes or once you reach REM sleep.
• You may read or sit quietly between naps, but avoid stimulants, phone calls or screens.

8. After the study

Your lab team will remove sensors and review initial data. Next steps:

• Schedule a follow-up appointment with your sleep doctor to go over results.
• Continue keeping a sleep diary if recommended.
• Discuss treatment options (medications, lifestyle changes, scheduled naps).

9. Additional tips

• If you have mobility issues, let the lab know so they can make accommodations.
• Bring any special pillows or blankets you need for comfort—but the lab environment must remain safe and sensor-compatible.
• If you’re anxious about needles or electrodes, talk with staff—they’re trained to make the process as smooth as possible.

10. Next steps and resources

A narcolepsy sleep study is a critical tool in diagnosing narcolepsy or other sleep disorders. Doing your part—following this checklist—leads to clearer results and a faster path to the right treatment plan.

If you’re unsure whether narcolepsy could be causing your daytime sleepiness or other symptoms, you might consider doing a free, online symptom check, using the doctor approved Ubie Symptom Checker (https://ubiehealth.com/). It’s a quick way to gather insights before or between doctor visits.

As always, speak to a doctor about any concerns—especially if you experience serious symptoms such as sudden loss of muscle control (cataplexy), sleep paralysis or hallucinations. If you ever have life-threatening or severe issues, seek immediate medical attention.

With this “Preparing for narcolepsy sleep study checklist” in hand, you can approach your sleep study equipped and confident. Good luck, and here’s to clearer answers and better sleep ahead!
