Brief Summary

The overarching goal of this research study is to determine "proof of concept" of effect of a non-invasive sleep aid device on sleep and performance during sleep opportunities (naps) that occur during and after simulated night shift work.

Aim 1: To determine the effect of the ApolloNeuro device on sleep duration, sleep architecture, blood pressure, heart rate variability, and subjective ratings of sleep quality during and after simulated night shift work.

Aim 2: To determine the effect of the ApolloNeuro device on post-sleep psychomotor performance.

Detailed Description

Night shift workers suffer from poor sleep quality, high levels of fatigue, and irregular sleep patterns. The overarching goal of this research study is to determine "proof of concept" of effect of a non-invasive sleep aid device on sleep and performance during sleep opportunities (naps) that occur during and after simulated night shift work. The device is commercially available and worn on the wrist (the ApolloNeuro). We will use a laboratory-based, randomized crossover trial with two conditions tested. With 24 total subjects enrolled and 20 total completing the study as designed, we have 80% power to detect a moderate to large effect size difference between the two conditions tested. Study findings will guide a "go-no-go" decision for future, large-sample studies.

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: CROSSOVER
• Primary Study Purpose: BASIC_SCIENCE
• Blinding Strategy: SINGLE

Study Groups

Apollo device applied followed by no device applied

Participants will be randomized to first wear the Apollo Neuro device immediately before, during, and immediately after sleep opportunities during the study protocol. Next, the participant will complete the protocol without the device.

Group Type: EXPERIMENTAL

Wrist worn vibro-acoustic device

Intervention Type: DEVICE

The Apollo device is a wrist worn device that is similar to a typical wristwatch. It emits a vibration pattern based on settings selected on a designated mobile app.

No device applied followed by the Apollo device applied

Participants will be randomized to first complete the protocol without the Apollo Neuro device applied then complete a condition with the Apollo Neuro device applied immediately before, during, and immediately after sleep opportunities during the study protocol.

Intervention Type: DEVICE

The Apollo device is a wrist worn device that is similar to a typical wristwatch. It emits a vibration pattern based on settings selected on a designated mobile app.

Eligibility Criteria

Inclusion Criteria

1. are 18 years of age or older;

2. have not been diagnosed or told by a healthcare clinician that they have a medical condition that may impact their blood pressure or cardiovascular health/system;

3. can abstain from smoking tobacco or chewing tobacco / nicotine products during the protocol and data collection;

4. can abstain from alcohol and moderate to high intensity exercise during the protocol and data collection;

5. are not prescribed medications or take over the counter medications that may impact blood pressure or heart rate (a team physician will review any reported medications identified during screening);

6. do not have a physical condition that may interfere with application of non-invasive devices on the wrist, upper arm, or chest for purposes of data collection with non-invasive devices;

7. feel that they can avoid working and complete the study protocol without interruption.

8. a public safety or healthcare shift worker based on standard licensing / certification requirements in the state of Pennsylvania.

Exclusion Criteria

An individual will be excluded if they report:

1. a medical condition or diagnosis that may impact their blood pressure or heart rate;

2. taking any standing medications or prescriptions, other than over the counter medications or contraceptives, that may impact their blood pressure or heart rate;

3. are unable to adhere to the study protocol that involves abstaining from alcohol, tobacco products (nicotine), and moderate to intense exercise during the study protocol and data collection periods;

4. have a physical condition that may limit use of non-invasive devices applied to the wrist, upper arm, or chest for data collection purposes.

5. being pregnant.

6. "heavy" alcohol use as defined by the CDC (8 or more drinks per week in women or 15 or more drinks per week in men)?

Because participants will have their sleep interrupted during the in-lab sleep opportunity, it is important that staff and the study team know if the participant has ever experienced the following:

A] Sleep Paralysis; B] Night Terrors; C] Have Obstructive Sleep Apnea which requires the use of a CPAP Device; D] Become angry towards others when abruptly woken up; E] Become physical towards others when abruptly woken up.

Mild annoyance and feelings of fatigue or sleepiness with being woken by staff is expected and not a reason for exclusion in this research study.

Answering YES to any of the above (A-E) will result in a discussion with the study team physician to discuss with the individual and make a determination if the individual can or should participate in this research study.

All who voluntarily participate should be without significant health issues and without health concerns that may affect their blood pressure.

All who voluntarily participate should not be on medications that fall within the following categories:

A] Antihypertensives; B] Analgesics; C] Beta blockers; D] Diuretics; E] Stimulants; F] Sedatives; G] Steroids.

Participants must not take any medications with sedative effects or effects on sleep during the study protocol and data collection periods (such as NyQuil).
