Abstract
The purpose of this study was to examine the effects on sleep of two different environments that protect against chemical threats. Ten (7 male and 3 female) regular Canadian Forces personnel were divided into two groups and performed various command post (CP) duties for 24 hours while in a chemical threat scenario environment wearing Individual Protective Ensemble (IPE MOPP 4) or in a Collective Protective Facility (COLPRO) wearing IPE MOPP 0. During their trials, their sleep was monitored and recorded using actigraph technology. Results: Soldiers had significantly less sleep in the IPE MOPP 4 ensemble (mean ± sd, 3.2 ± 1.6 hours), compared to the COLRO environment, (5.0 ± 1.3 hours). The sleep quality was also significantly poorer as they had more awakenings during their sleep periods in the IPE MOPP4 ensemble (3.0 ± 1.9) compared to COLPRO (1.1 ± 1.1). Conclusions: It was concluded that 24 hours in IPE MOPP 4 produced sleep deprivation in soldiers that lead to severe decrement in cognitive and physical performance.
