Navy Sailors Health Behavior: A Multi-Factor Analysis of Circadian Rhythm on Naval Operational Capability

Abstract

Objective: The objective of this research was to determine the impact of circadian rhythm disorders on sleep disorders, fatigue and health problems of navy sailors from the perspective of their health behavior. During its voyage, navy crews have obvious problems such as sleep disorders and fatigue, among which the circadian rhythm disorder was the most common. Warning system, special environment at sea, pressure and other factors can lead to the occurrence of circadian rhythm disorders. Methods: The primary data was used in this research with a sample size of 278 and Smart PLS was used for statistical analysis. Results: According to empirical data, the impact of circadian rhythm disorders was significant on sleep disorders, fatigue and health problems of navy sailors. The research is novel in the literature because very few studies have discussed the circadian rhythm disorders in the context of navy sailors. Conclusion: The research implications in the theory are reliable to enhance the body of knowledge of circadian in the significant way. Furthermore, the study has some practical implications to work on to enhance the practices to improve the health of navy sailors during their long time in the sea.
