You can drink preworkout with little salt in it to be more efficient during workouts. But if you drink sea water before a workout, you’ll die. Why?

Body needs to maintain not only certain amount of water and salt present, but also a specific balance between them to be upheld. If this balance is lost (having in body comparatively too much salt or too much water), you will feel bad, and in extreme cases there can be damage to your body.

When you exercise, you are going to sweat (also exhale much). You lose much water and some salt this way. You need to replenish them, and in the right balance. Seawater is too salty, it will make the balance even worse. Water without any salt can also flip the balance in bigger amounts – and you will want bigger amounts when you sweat stuff out. Water with some salt is exactly what you need.
