Exploratory Study in Healthy Volunteers to Define Circadian Relationships Between Social Behavior, Blood Pressure and Metabolomics

University of Pennsylvania·observational·Posted Sep 26, 2014·Updated Mar 17, 2026

In Brief

An observational study for Healthy. Completed, enrolled 6 participants across 1 site.

Detailed Summary

As citizens of the information age, humans leave digital traces of behavior in their communication and movement patterns through our cell phone. The Global Positioning System (GPS) technology tracks the way persons commute to school or work or when visiting family and friends. Circadian rhythmicity describes the concept that many of the bodily functions follow a roughly 24-hour rhythm. Usually, the ability to do concentrated and focused work is best during daytime while humans rest and sleep during nighttime. The current study wishes to look for a relationship between patterns in participants' cell phone use (Android only at this point) and several of their bodily functions.
