The main goal of this study is to explore whether a person's typical sleep habits are related to their health and functioning. Our goal is to allow you to complete as much of the study as possible on your own time, at your convenience, with as little as possible in the lab. That said, there are a number of things that can only be done in the lab.

We appreciate your time and effort. You will be paid $500 if you complete the study. If you withdraw early, your payment will be prorated. This study does not ask you to change your sleep schedule and it does not involve any study medications.

This study consists of:


Before doing anything else, you will be asked to complete an online survey. This survey may take 30-60 minutes to complete, and asks for your contact information, information about you, and details about your sleep, how you feel during the day, and your medical history. If you qualify for the study, you wll be invited for VISIT 1.

If you don't qualify, we will tell you why. If it is because of a medical or other problem that came up on the survey, we can direct you to resources that might be able to help.

Whether you qualify or not, we will send you a free report that details your scores on the questionnaires you completed.

Those that qualify will be invited to schedule an appointment for VISIT 1.


For the initial visit, you will be asked to come in to our office and meet with a member of the research staff.

You will be asked more questions about your sleep, medical, and family history, and undergo a brief physical exam (height, weight, blood pressure, etc.). You will also be asked questions about your diet, exercise habits, use of substances (like alcohol tobacco, and caffeine), mood, thoughts, and feelings, and you will be asked to fill out a packet of questionnaires.

Part of this visit involves completing two reaction time tests using handheld devices (each takes 10 minutes).

We will then collect a saliva sample for DNA purposes.


During your initial visit, we will show you how to use the portable sleep monitor (Embletta) that you will take home and use for one night. You will be provided with a pre-paid UPS envelope in which to send the sleep monitor back to us. You will be expected to use it the night of the initial visit, and send it back the next day. This will be used to determine if you have sleep apnea.


After your home sleep test is scored (usually takes about a week), provided that you do not have sleep apnea, you will be invited back for a second visit. During this visit, you will be given equipment and instructions to assist in monitoring your day-to-day sleep pattern for a period of 2 weeks.


This home study will include: (1) 1-minute sleep diary that you fill out every morning, (2) actigraph device (looks like a digital watch) that records movement and light, which you wear 24/7, (3) a handheld device with a reaction time test, and (4) a blood pressure monitor. The reaction time test takes 10 minutes and will need to be completed 3 times each day for 5 days. You only wear the blood pressure monitor for 24 hours. We will give you pre-paid envelopes to return all the equipment.


After you are finished with the home study, your results will be analyzed and, if you qualify, you will be asked to spend three nights (and three days) in the sleep lab. All meals will be provided.

Most participants are a little nervous about sleeping in the lab, but remember that we will do our best to make your stay in the lab as comfortable as possible -- it helps us make sure the data are reliable and we want participants to recommend our research study to friends.

During the first two nights, your sleep will be recorded using a number of sensors that monitor your breathing, brain activity, etc. On the third night, no sensors will be applied.

On the day after the first night, we will guide you through a set of tests that measure your levels of alertness and sleepiness across the day.

On the day after the second night, you will undergo a test that measures (using special sensors) your blood flow and heart function. You will also complete more computer-based tests of alertness and sleepiness.

On the morning after the third night, you will undergo a special type of blood test, called an OGTT, that includes a series of blood draws across several hours. During the OGTT, a nurse will insert a catheter (needle with tube) into your arm vein for blood collection. Catheters make it possible to take frequent samples of your blood without having to puncture skin each time. There will be 21 blood collections for a total of 105 milliliters, which is about 1/4th the amount of blood taken during a typical blood donation. After the test is finished, you are free to leave. You will be provided a meal before you leave.
