Surround the hole with wet leaves, then put a large piece of plastic down over the hole and weigh it down. Condensation will collect in your container and you’ll be able to drink it. When it rains, make sure that you are filling up containers to catch the fresh water to keep you hydrated for the long run.

Obviously, drinking seawater will kill you, but, if you have even a few items from your broken plane or boat then you can make a “solar-still,” which will allow you to turn salt-water into distilled water (See www.wikihow.com/Make-Water-in-the-Desert). It can even be used to recycle your urine into fresh water.

What Can You Drink When Stranded at Sea?

• Short Water Rations. When you have a limited water supply and you can’t replace it by chemical or mechanical means, use the water efficiently.
• Desalting Kits.
• Water From Fish.
• Sea Ice.

2. Finding a source of drinking Water

1. Step 1: Dig a hole in the sand up near the edge of the trees.
2. Step 2: Place a container in the center of the hole.
3. Step 3: Fill the gaps surrounding the container with anything wet, such as wet leaves.

Seawater is toxic to humans because your body is unable to get rid of the salt that comes from seawater. Your body’s kidneys normally remove excess salt by producing urine, but the body needs freshwater to dilute the salt in your body for the kidneys to work properly.

The body tries to compensate for fluid loss by increasing the heart rate and constricting blood vessels to maintain blood pressure and flow to vital organs. You’re also most likely to feel nausea, weakness and even delirium.

Drinking saltwater itself doesn’t make you crazy. It does make you dehydrate faster because your kidneys need more water to process the salt than you get from the sea water though and that can result in many symptoms including confusion.

Risks: Drinking salt water on an empty stomach may cause nausea and vomiting. A saltwater flush may increase your risk of sodium overload. Sodium overload may lead to high blood pressure.

Saltwater itself is not bad for your skin, but constant exposure to a combination of salt, sun and sand can irritate and dry out skin, especially for those with a history of dry skin or other issues like eczema.

Your body uses salt to balance fluids in the blood and maintain healthy blood pressure, and it is also essential for nerve and muscle function.

Reducing the amount of sodium in your diet can: Lower your blood pressure. The amount of fluid in your blood decreases, which leads to lower blood pressure. Reduce your risk of a heart attack.
