Purpose

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.

Experimental
Group A- Natural Compound A to Natural Compound B to Natural Compound C
- 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.
  • Other: Natural Compound A (Hinoki essential oil)
    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).
  • Other: Natural Compound B (Lemon essential oil)
    Participants will use "Natural Compound B" 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).
  • Other: Natural Compound C (Control/Water)
    Participants will use "Natural Compound C" 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).

Detailed Description

Considerable research has been conducted on the effects of environmental exposure on human diseases. This is also known as "exposome" research. However, there is limited research on the impact of beneficial exposomes found in the natural environment. The researchers would like to identify and measure the benefits of these naturally occurring compounds on holistic human health. Through blood specimens, the researchers will observe biomarkers such as cortisol levels and inflammatory markers. Data will be collected from wearable sensors to observe the effects of beneficial exposomes on areas such as cardiovascular health and sleep quality. There will be surveys to understand well-being, stress, and mood. Through such observations, this study aims to understand the positive impacts of intentional exposure to selected compounds found in nature.
