Safeguarding Seafarers: The Crucial Role Of Hydration in Maritime Work

For seafarers, the importance of maintaining hydration levels cannot be overstated. The demanding nature of maritime work, often conducted in challenging environments, makes it essential for seafarers to stay well-hydrated to ensure their safety, well-being and overall job performance, reports Britannia P&I.

Importance of hydration

The recommended daily water intake for adult males is 2.5 liters, while females should aim for 2 liters. Most of this water should come from drinks, with the remaining 30-40% from food. It is also important to note that water is the best type of fluid to drink. These guidelines serve as a baseline, but individual requirements may vary based on factors such as age, body composition, climate, and physical activity.

Best practices to ensure adequate hydration

● Consistently drink water throughout the day, even if you do not feel thirsty. Thirst is often a delayed indicator of dehydration
● Sip water rather than drinking lots of water in one go, to avoid it passing straight through you
● In addition to water, include beverages with electrolytes to replenish salts lost through sweating
● Pay attention to the color of your urine; pale yellow indicates good hydration, while dark yellow or amber signals dehydration
● Limit the consumption of alcoholic and caffeinated beverages, as they can contribute to dehydration
● Keep a reusable water bottle within reach to encourage regular water consumption.

The maritime work environment can significantly impact hydration levels. Extended periods of work, exposure to extreme temperatures, and physically demanding tasks can lead to increased fluid loss through sweating. Seafarers must be especially mindful of their hydration in these conditions and try to consume more fluids.

Working in warm climates or during the summer months requires extra attention to hydration. The body acclimatizes to hot conditions over time, but during the adjustment period, seafarers are at a higher risk of heat-related illnesses and dehydration. Adequate rest, shade, and frequent hydration breaks are essential during this period to minimize the risks associated with excessive heat. Seafarers who are used to working in hot conditions tend to sweat more efficiently, while those who are not may lose more salt in their sweat. Adding extra salt to food can help, but salt tablets are not recommended as they do not enter the body as quickly.

Not drinking enough water can lead to kidney stones, which a lack of water intake or excessive calcium in the diet can cause. Foods high in calcium include beetroot, asparagus, soy products, and some nuts. It is important to maintain hydration levels to avoid these issues.

It is important to raise awareness around the significance of staying adequately hydrated; campaigns can help prevent these problems and improve crew members’ overall well-being through education. The importance of having a crew with adequate knowledge of hydration can be shown in the International Seafarers’ Welfare and Assistance Network’s Quench Campaign whereby 16% of participants thought you could survive for a month without water. These participants consumed the least amount of water throughout the campaign, conversely, participants with the greatest knowledge of hydration, unsurprisingly, consistently consumed the most water.

Staying hydrated is of paramount importance for seafarers. Adequate water intake, adherence to guidelines, and adopting best practices are essential to ensure the well-being and performance of the crew. The work environment, especially in warm conditions, can pose challenges to hydration, making it imperative to remain vigilant. By following these guidelines and staying informed through initiatives, seafarers can safeguard their health and safety while at sea.
