The wristband is a device that records your activity level and sleep.

It provides information about your general activity, sleep schedule, naps, time awake, and information about your sleep quantity and quality.

You will wear the wristband all day and all night throughout the two-week study periods.

Yes. You can wear it while you shower or bathe, but remove it if you are going into a hot tub, sauna, or pool.

Stop using it and let the study team know right away if a rash or reddening appears.

If the device becomes damaged, remove it and contact us.

The wristband should not need to be cleaned while you have it. However, if you must clean it, use a soft cloth lightly moistened in mild detergent (such as dish soap) and water to gently remove dirt and stains. Do NOT use abrasives or alcohol as they may damage the wristband.

After each two-week study period, please return the wristband following the instructions in the Shipping section of the study booklet or website.

You do not need to charge or do anything else with the wristband. It is all set up so all you need to do is wear it.
