NCT06093464

Brief Summary

The purpose of this study is to explore the positive, holistic health outcomes resulting from regular exposure to naturally occurring compounds predicted to have health benefits. The researchers hope to learn how the human body is influenced by regular exposure to these compounds.

Outcome Measures

Primary Outcomes (4)

  • Resting Heart Rate

    Change in resting heart rate measured by wearable devices

    Baseline; 26 weeks

  • Heart Rate Variability

    Change in resting heart rate measured by wearable devices

    Baseline; 26 weeks

  • Change in sleep quality measured as duration of sleep stages

    Duration of each sleep stage \[i.e. light, deep, rapid eye movement (REM), wake stages\] overnight. Sleep quality will be measured via a wearable device. Sleep quality will be compared to baseline through the other intervention phases.

    Baseline; 26 weeks

  • Profile of Mood States

    Change in mood states, a 65 item scale that allow for the quick assessment of transient, fluctuating feelings and enduring affect states.

    Baseline; weeks 2, 6, 10, 14, 18, 22, and 26

Secondary Outcomes (8)

  • Metabolome

    Baseline; weeks 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, and 26

  • Proteome

    Baseline; weeks 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, and 26

  • Transcriptome

    Baseline; weeks 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, and 26

  • Well-being

    Baseline; weeks 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, and 26

  • Perceived Stress

    Baseline; weeks 2, 6, 10, 14, 18, 22, and 26

  • +3 more secondary outcomes

Study Arms (3)

Group A- Natural Compound A to Natural Compound B to Natural Compound C

EXPERIMENTAL

* Cycle 1 (4 weeks): use diffused "Natural Compound A" (essential oil) in a diffuser every night when sleeping * Cycle 2 (4 weeks): will not use compounds/diffuser (wash-out period) * Cycle 3 (4 weeks): use diffused "Natural Compound B" (essential oil) in a diffuser every night when sleeping * Cycle 4 (4 weeks): will not use compounds/diffuser (post-intervention observation period) * Cycle 3 (4 weeks): use diffused "Natural Compound C" (control) in a diffuser every night when sleeping * Cycle 4 (4 weeks): will not use compounds/diffuser (post-intervention observation period) There will be 3 natural compounds; the intervention compounds essential oils and are commercially available and there is a control compound (water). They will be used as intended with diffusers.

Interventions

Participants will use "Natural Compound A" in a diffuser every night for 4 weeks. Diffuser will be placed near participant's bed and will be used during the entire time they are asleep (about 8 hours, every night).
