What if you drink saltwater?

SaltwaterSeventy one percent of our planet’s surface is wet with water. So can we consume it?

The short answer: No, thanks (or no thanks) to salt.

Our bodies need both salt and water to function. But too much of salt and water results in harmful effects to our bodies. If you are consuming seawater, the results are spectacularly disastrous. The salinity of seawater is almost four times that of our bodily fluids.

So, if you’re guzzling seawater, you are not taking in any water but are incurring a net loss, leading to depleted body fluids, muscle cramps, dry mouth, and yes, thirst.

Consuming small amounts of saltwater would not kill you. But salt and water are best consumed separately—and any salt intake should be accompanied by freshwater.
