This might be a bit of a head scratcher, but despite the fact that you can easily float in the Dead Sea, you can still drown. In fact, the Dead Sea was named the second most deadly place to swim in Israel. It’s difficult to move easily within the lake, making it tricky if you end up in a dangerous position. Also, if you drink too much of the salt water, it can deplete your electrolytes and be hard on your kidneys, essentially poisoning you with too much salt.
