Q: Does a person absorb enough of the salt in a nasal saline wash to raise blood pressure?
A: Nasal saline washes are made to have the same salt concentration as the body. This means you can wash the inside of your nose with the solution without getting a significant absorption of salt into the body. Proper use of a balanced nasal irrigation solution will not increase blood pressure. Let the solution fall out of your nose or mouth, you don’t want to swallow it.
