Smart Pillows for Enhancing Sleep Quality

Subjective sleep quality will be measured by the Pittsburgh Sleep Quality Index (PSQI). The PSQI score ranges from 0-21. A higher score indicates worse sleep quality. The PSQI will be administered prior to use of the study pillow and again after discontinuing use of the study pillow.

Subjective sleep quality will also be measured by a novel questionnaire created for this project. Questionnaire score ranges from 3-15. A higher score indicates better sleep quality. Participants will be asked to complete this questionnaire 14 times during their participation: once daily for the 7 days prior to initiating use of the study pillow (Day -7 through Day -1) and once daily for the last 7 days of study pillow use (Day 8 - Day 14).

As part of measuring objective sleep quality, total sleep time will be measured using the Fitbit Inspire 3 (an actigraphy watch). Participants will be asked to wear the actigraphy watch continuously for the 7 days before initiating use of the study pillow (Day -7 through Day -1) and continuously for the last 7 days of study pillow use (Day 8 through Day 14).

As part of measuring objective sleep quality, sleep periods (light and deep sleep) will be measured using the Fitbit Inspire 3 (an actigraphy watch). Participants will be asked to wear the actigraphy watch continuously for the 7 days before initiating use of the study pillow (Day -7 through Day -1) and continuously for the last 7 days of study pillow use (Day 8 through Day 14).

As part of measuring objective sleep quality, REM and non-REM sleep time will be measured using the Fitbit Inspire 3 (an actigraphy watch). Participants will be asked to wear the actigraphy watch continuously for the 7 days before initiating use of the study pillow (Day -7 through Day -1) and continuously for the last 7 days of study pillow use (Day 8 through Day 14).

The study pillow (Nitetronic Z6 smart pillow) will collect data on total time spent snoring and the intensity of the snoring. Participants will be asked to use the study pillow for 14 consecutive nights during their participation (Day 1 through Day 14).

Depressive symptoms will be measured using the Center for Epidemiologic Studies Depression Scale, 8-item (CES-D-8). The CES-D-8 score ranges from 0 to 8. A higher score indicates more severe depressive symptoms.. The CES-D-8 will be administered prior to use of the study pillow and again after discontinuing use of the study pillow.

Blood oxygen level will be measured using the Fitbit Inspire 3 (an actigraphy watch). Participants will be asked to wear the actigraphy watch continuously for the 7 days before initiating use of the study pillow (Day -7 through Day -1) and continuously for the last 7 days of study pillow use (Day 8 through Day 14).

Physical activity level will be measured using the Fitbit Inspire 3 (an actigraphy watch). Participants will be asked to wear the actigraphy watch continuously for the 7 days before initiating use of the study pillow (Day -7 through Day -1) and continuously for the last 7 days of study pillow use (Day 8 through Day 14).

Subjective cognitive function will be measured by a two-question questionnaire: 1) 'How would you rate your memory at the present time? Would you say it is excellent, very good, good, fair, or poor?' and 2) 'Compared to the previous month, would you say your memory is better now, about the same, or worse than it was then?' The two-question questionnaire will be administered prior to the use of the study pillow and again after discontinuing the use of the study pillow.

Objective cognitive function will measured by the Montreal Cognitive Assessment (MoCA). The MoCA score ranges from 0-30. A higher score indicates better cognitive function. The MoCA will be administered prior to the use of the study pillow and again after discontinuing the use of the study pillow.

Subjective sleep quality will be measured by the Pittsburgh Sleep Quality Index (PSQI). The PSQI score ranges from 0-21. A higher score indicates worse sleep quality. The PSQI will be administered to sleep partners of study participants prior to the participant's use of the study pillow and again after the participant discontinues use of the study pillow.

Subjective sleep quality will also be measured by a novel questionnaire created for this project. Questionnaire score ranges from 3-15. A higher score indicates better sleep quality. Sleep Partners will be asked to complete this questionnaire 14 times during their participation: once daily for the 7 days prior to the participant initiating use of the study pillow (Day -7 through Day -1) and once daily during the participant's last 7 days of study pillow use (Day 8 through Day 14).

As part of measuring objective sleep quality, total sleep time will be measured using the Fitbit Inspire 3 (an actigraphy watch). Sleep Partners of study participants will be asked to wear the actigraphy watch continuously for 7 days before the participant initiates use of the pillow (Day -7 through Day -1) and continuously for the last 7 days of the participant's pillow use (Day 8 through Day 14).
