Two serious challenges facing seafarers heading into the warmer seasons are sun exposure and dehydration. An USCG alert describes both, along with solutions and recommendations to avoid while working on and off the vessel, reports the American Club.
The USCG TAC Plus Q1 2025 Newsletter highlights these significant health concerns for seafarers during warmer seasons.
Sun Exposure Risks and Prevention
Prolonged sun exposure can lead to serious skin damage, increasing the risk of skin cancer. To mitigate these risks, the use of sunscreens with a Sun Protection Factor (SPF) of 45-50 is recommended, along with protective clothing and hat coverings. Certain medications, such as steroids, antifungals, antihistamines, antibiotics, retinoids, and some antidepressants, can heighten skin vulnerability to sun damage. Seafarers are advised to read medication labels and consult healthcare providers about potential risks.
Dehydration Awareness and Management
Dehydration is a common concern for seafarers, especially in warmer climates. It occurs due to excessive fluid and electrolyte loss from sweating. Medications like antihypertensives, diuretics, laxatives, chemotherapy drugs, antidepressants, lithium, and caffeine can increase the risk of dehydration. Common signs include thirst, less frequent urination, dark urine, dry skin, stomach cramps, and fatigue. In severe cases, heat stroke can develop, leading to confusion, loss of consciousness, dangerously low blood pressure, and acute kidney failure if untreated.
Recommendations for Seafarers
- Sun Protection: Apply sunscreen with SPF 45-50 regularly and wear protective clothing and hats.
- Hydration: Consume adequate fluids daily—approximately 3.7 liters for men and 2.7 liters for women.
- Medication Awareness: Be aware of medications that may increase sensitivity to sun exposure or risk of dehydration.
- Monitor Symptoms: Stay alert to signs of dehydration and seek medical attention if necessary.
By following these guidelines, seafarers can reduce the risks associated with sun exposure and dehydration, ensuring better health and safety while at sea.
