Navigating the Depths of Cardiovascular Effects on Submariners

Area of Science:

• Occupational Health
• Environmental Medicine
• Cardiovascular Health

Background:

• Submariner deployment involves confinement, inactivity, caloric excess, and circadian disruption.
• These factors contribute to metabolic disturbances, sleep deprivation, and physiological/cognitive abnormalities.
• Submariners experience vitamin D and B12 deficiencies due to limited sunlight and poor nutrition, increasing cardiovascular risk.

Purpose of the Study:

• To identify key health risk factors in the submariner environment.
• To explore the associations between these risks and cardiovascular health outcomes.
• To propose mitigation strategies for submariner well-being.

Main Methods:

• Review of environmental factors and their physiological impacts.
• Analysis of reported health issues including metabolic disturbances, vitamin deficits, and obesity.
• Identification of cardiovascular risk factors such as heart rate variability changes.

Main Results:

• Submariner environment poses risks: confinement, inactivity, caloric excess, circadian disruption.
• Metabolic disturbances, cardiovascular risks, and sleep deprivation are linked to disrupted circadian rhythms.
• Vitamin D/B12 deficiencies, high obesity prevalence, and altered heart function are prevalent.
• Leptin resistance and lifestyle contribute to obesity and cardiovascular risks.

Conclusions:

• Submariner health is compromised by unique environmental and lifestyle factors.
• Addressing circadian rhythm stability, vitamin intake, and lifestyle is crucial.
• Proactive health management can mitigate cardiovascular disease vulnerability and enhance submariner well-being.
