What should you avoid drinking when stranded in the sea?

1. Rainwater

2. Freshwater from fish

3. Seawater

4. Watery fluids from birds

The correct answer is: Seawater

When stranded in the sea, drinking seawater should be avoided because it contains high levels of salt. Consuming seawater can lead to dehydration and adverse health effects. The human body requires salt to function properly, but the concentration of salt in seawater is much higher than what is needed. Drinking it causes the body to work harder to excrete the excess salt, which ultimately leads to further dehydration. In contrast, the other options, such as rainwater and freshwater from fish, typically offer hydration benefits and are safer alternatives to consume. Even fluids from birds can be a potential source of hydration. Therefore, the critical takeaway is that while in a survival situation at sea, it is essential to avoid seawater due to its dehydrating effects.
