Low-frequency vibrating mat for sleep and daily stress recovery

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This randomized, controlled study assigns healthy adults aged 18-45 to either a home-based vibrating mat program or a no-mat control for three weeks. The experimental group uses a low-frequency whole-body vibration mat for three 15-minute sessions, 3-4 days per week, while both groups complete questionnaires, brief affect check-ins, and daily logs. Investigators collect heart rate variability and resting EEG at two lab visits before and after the program to measure physiological changes related to stress recovery, sleep, mood, and attention. Outcomes compare group differences over time and explore relationships between EEG patterns and HRV changes.

Why it matters

Who can join: the full rules

Inclusion Criteria:

* Adults 18-45 years.
* Able to provide written informed consent.
* Apparently healthy and free of unstable cardiovascular, neurological, or psychiatric conditions per screening.
* Cleared for low-to-moderate intensity whole-body vibration delivered supine/recumbent on a mat.
* Willing and able to comply with study procedures: two lab visits; 3-week home protocol (3-4 days/week); three 15-min sessions; brief affect check-ins and daily logs.
* Willing to abstain from caffeine, alcohol, and strenuous exercise for 24 hours before each lab visit and to attend visits at the same time of day.
* Able to lie supine for 15 minutes and follow instructions for the HRV device.

Exclusion Criteria:

* Implanted electronic medical devices (e.g., pacemaker, neurostimulator).
* Uncontrolled hypertension or severe vestibular disorders.
* Current substance dependence.
* Medications known to markedly affect autonomic function or sleep architecture (e.g., beta-blockers, antiarrhythmics, sedative-hypnotics, antidepressants with strong autonomic effects).
* Diagnosed neurological or psychological disorders that substantially affect emotional processing or autonomic regulation (severe psychiatric conditions).
* Prior extensive experience with vibration therapies (to minimize expectancy bias).
* Any condition judged by study staff to contraindicate vibration exposure or preclude safe participation (including inability to tolerate supine/recumbent position).
* Unwillingness to refrain from initiating new structured exercise or relaxation programs during the study period.
