To preserve at least some form, the human body requires a minimum of a liter of water per day, but you can survive with a diet of 55-220 ml. Even if you have a good supply of water, while surviving at sea, immediately start rationing it, given these minimum standards. Until you manage to replenish stocks. Do not soften the diet until final salvation, as you cannot know exactly how long you will have to live on your stock.
Extraction, collection and saving of drinking water while surviving at sea, reducing water demand.
Drinking water collection.
When surviving at sea, use all possible containers to collect drinking water day and night. Usually you will see the approach of a rain flurry and you will have time to build a catchment from tarpaulin or plastic, which will go much more than in different banks. Fasten the tarpaulin overnight so that its corners are raised to collect dew.
, do not eat, especially food containing protein, which includes fish and seaweed, it requires a lot of water to digest. Carbohydrates (sugars and starches) need less to digest water.
Getting water from sea ice.
Drinking water can be obtained from ice. But the young sea ice is salty. Use only old sea ice, which can be recognized by its bluish-gray color and rounded outlines. It can be melted or sucked, because after a year or more, the ice loses its salt. In summer, there may be potable water in puddles on the surface of sea ice. Unless, of course, they were formed not by splashes of waves. Try this water very well before drinking it, as any amount of salt absorbed will only increase thirst..
Fish water extraction.
Drink watery fluid in the ridge and in the eyes of large fish. Carefully cut the fish in half to get to the water and suck out your eyes. If you have so little drink that you are forced to take such measures, then do not drink all the other body fluids of the fish, as they are rich in proteins and fats, and this will cause a greater consumption of water from the body’s reserves to digest them than these liquids themselves will give.
If you are on a liferaft, its equipment may include solar and chemical desalination. They have relevant instructions. Activate solar desalination plants immediately, use desalination tablets only when the weather is unfavorable for the solar desalination plant, and collecting dew and rainwater is ineffective.
When surviving at sea, try the following:.
Do not drink seawater.
Do not drink urine.
Do not drink alcohol.
Do not smoke.
Do not eat if there is not enough drinking water.
Sleep and peace are the best ways to overcome periods of lack of drinking and food, but provide adequate protection from direct sunlight when you sleep during the day. When the sea is restless, get attached to the boat, take cover and try to bear the storm as calmly as possible. The main thing here is to relax, or at least try to relax..
