So this is no myth everyone who even for a second feels a sore or itchy throat coming on gargle like youâve never gargled beforeâ¦..IT REALLY DOES HELP!!!!!! Not only does salt water help with sore throats, it also helps an abcess tooth. I felt an abcess coming on last week and the pain was irritating. I decided to try to rinse the area with salt water. The pain IMMEDIATELY went away and did not become inflamed any further.
1 Dehydration can sometimes cause blood pressure to drop. 2  However, dehydration does not automatically signal low blood pressure. 3  Fever, vomiting, severe diarrhea, overuse of diuretics and strenuous exercise can all lead to dehydration, a potentially serious condition in which your body loses more water than you take in.
However, a sudden drop in blood pressure â even a change of just 20 mm Hg â can cause dizziness or fainting, according to the American Heart Association. Sit down if you feel dizzy and drink water, because dehydration can cause a drop in blood pressure.
