This study, called the "Beneficial Exposome Study," is looking at how natural compounds might improve your health. Researchers want to understand the positive effects of regular exposure to Hinoki essential oil, Lemon essential oil, or plain water (as a control) diffused nightly for 4 weeks. They will measure your resting heart rate, heart rate variability (how your heart rate changes between beats), and sleep quality over 26 weeks to see if these compounds have a benefit. You can join if you are 18 or older, speak English, live in the US, and do not have certain medical conditions like epilepsy or allergies to the Cupressaceae plant family. The current recruitment status is unclear.

Study design

This interventional study plans to enroll 40 healthy participants. Participants will be assigned to use one of three different diffusers (Hinoki essential oil, Lemon essential oil, or water) each night.

What's involved

Participants will use a diffuser with their assigned compound every night for 4 weeks while they sleep. Measurements of heart rate and sleep quality will be taken at the beginning of the study and again at 26 weeks.

Compensation

Not stated in the trial record.

Follow-up

Participants will be followed for 26 weeks after the start of the study, with final measurements taken at that time.
