 
Night 1:
Orientation: You will be oriented to the lab. One of the staff members will show you around and show you to your room.
Actiwatch: You will be fitted with an actiwatch that you will wear for your entire stay at the lab. This will be the same type of device that you wore for 2 weeks as part of the home study.
Sleep Diary: You will fill out a sleep diary while you are here in the lab, both before bed and when you wake up. This will be very similar to the one you filled out during the home study (but shorter).
Complete your evening sleep diary
Sleep Recording: While you sleep in the lab, your sleep will be recorded using a number of devices and sensors. These will include sensors on your head, face, chest, abdomen, and legs. This will be similar to the home sleep test you did a while ago, but with more sensors. The sleep technician will set you up and make sure everything is comfortable.
PVT Training (Reaction Time): You will complete several reaction time tests while here in the lab. Although you won’t be taking any tonight, you will be shown how to do it in the morning.
Lights Out: Your lights out will be within 15 minutes of your usual time, based on your sleep diary.
Day 1:
Lights On: Lights on will be within 15 minutes of your usual time, based on your sleep diary.

Sleep Diary: You will keep filling out your sleep diary while you stay in the lab.
Complete your morning sleep diary
PVT Tests (Reaction Time): You will complete 6-7 reaction time tests across the day. The first test will be when you wake up, and the last will be before you go to bed. The rest will be spaced across the day, 2 hours apart.

Nap Test: This test involves 4-5 naps throughout the day, spaced 2 hours apart. The test looks to see how long it takes you to fall asleep (with all of the testing equipment from the night before). Once you are asleep, the staff member will wake you up, so you don’t nap for long.
Questionnaire Packet: You will complete an online questionnaire packet – these will be the same questionnaires you filled out at the start of the study.

Pulse Wave Velocity: For this test, you will go down to the Clinical and Translational Research Center on the 1st floor of the hospital. This test involves measuring your blood pressure and then using a sensor to measure your pulse on three different parts of your body.
Medical History and Physical Exam: A trained nurse will perform a brief physical exam and ask you about your medical history.
Computer Testing: In the afternoon, you will complete a number of tests on the computer that measure your memory, attention, and other abilities.
To access the computer tests, open an Explorer window and navigate to C:\CHARTS\tests

Pack Up: This is your last morning in the lab. So you will need to pack up to get ready to check out.
Blood Collection: You will be taken back down to the Clinical and Translational Research Center for a blood collection that will take place over about 6 hours. This takes a long time because it involves giving you a standard amount of glucose and seeing how your body processes the blood sugar.
End of Study: After the blood test, you will get brunch and will be finished with the study.
