cities have been named after it economies have been built on it wars have been fought over and your life depends on it salt may be the most important and the most divisive mineral in history what is it worth to us today this is what if and here's what would happen if there were no salt in the world there are more than 14,000 uses for salt but to most of us it only means one thing high blood pressure back in the day your salary might have been paid in salt it could have preserved your food healed your wounds and brought good fortune today beyond being the reason why that burger that pretzel and those french fries taste so good right now salt is important for de-icing chemical processing water treatment farming and for several uses in the oil and gas industry it's also made up of two elements that on their own kill you but together they keep you alive want to see what happens when you put sodium in water do you know what chlorine does to you well when you put this and this together you get table salt also known as sodium chloride to deadly elements combined into one you can't live without salt has a number of crucial benefits like helping your body transmit nerve signals so that your muscles can relax and contract enabling your heart to pump blood it's also important for digesting nutrients and fighting infections but hold on there mister peanut you can have too much of a good thing while low blood sodium make us fatigue vomiting seizures or even death too much salt can end up accumulating between your cells thickening your blood making your heart work harder and often resulting in cardiac arrest your body naturally has about 40 teaspoons of salt in it or roughly 0.4% of your body weight but every time you cry sweat or pee you lose some of that salt and it needs to be replaced the American Heart Association recommends that adults get between 1,500 to 2300 milligrams of salt per day but that only amounts to one bag of chips or two California rolls meanwhile that burger and fries you are eyeing have about 3,400 milligrams so maybe you're thinking it's time to start cutting back on your salt intake well sure but don't cut it all out in the 1930s dr.
Robert McCants of Cambridge University's Department of experimental medicine got four volunteers to go ten days without salt first he had them sweat out all the salt in their bodies then he literally desalinated everything they consumed it wasn't long before the participants began to realize they weren't tasting much flavor in anything then fatigue set in and they became too tired to even eat signs of hyponatremia started to show which basically means that your blood cells start swelling because there's not enough salt in your blood to regulate how much water a cell will consume left untreated hyponatremia can result in seizures coma and death at the end of the trial participants were given salty foods and within minutes they could taste again and their energy quickly came back if that's just ten days without salt imagine if it simply ceased to exist we wouldn't last very long and not just us plants and animals need salt as much as we do the mere desalinization of our oceans would wipe out all our underwater algae cutting photosynthesis on earth in half land-based plant life would follow and soon we'd be facing an issue of too much carbon dioxide and not enough oxygen our climate would go crazy fluctuating between extreme hot and cold temperatures with a dramatic surge in hurricanes of course to mulches weather food shortages and a lack of oxygen would be even harder to process since you'd also be suffering from dizzying headaches vomiting and extreme fatigue any numbness or chest pain you might experience is probably an oncoming heart attack but instead of running for an overcrowded hospital get to the nearest convenience store if you're lucky there will still be some chips and Gatorade left on the shelves but that's assuming that no one else who's feeling totally helpless in the face of this mass desalinization event has seen this video look it's never going to happen but you'll be prepared for anything as long as you keep watching what if [Music]
