Operational Evaluation of a Photic Countermeasure to Improve Alertness, Performance, and Mood During Night-Shift Work on the 105-Day Study (105-Day Russian Chamber Study)

Completed Technology Project

Project Introduction

The 105-day isolation study was conducted at the Institute for Biomedical Problems (IBMP) from 31 Mar 09 to 14 Jul 09. Six crewmembers lived and worked in an isolation facility and participated in our study validating the efficacy and operational feasibility of a photic countermeasure to improve alertness and performance during night shift work occurring during a simulated expedition mission. Eighteen mission controllers who worked 24-hour extended duration shifts also participated in the study. Throughout the 105-day experiment, a variety of measurements were obtained to assess sleep, performance, alignment of the circadian system, and melatonin levels. All data were collected and analyzed and a manuscript is in preparation. More »
