1 Salt cleanses. 2  Not only does salt water flush out post-nasal drip and other bacterial material (just like any fluid would), a salty environment prevents bacteria from growing. 3  Just ask any medieval meat-eater how they kept their meat from going rancid, and youâll recall that salt is a bacteria-fighter.
Many things can cause your blood pressure to be too low, ranging from normal pregnancy-induced changes to dangerous underlying conditions, like heart problems or hormone disturbances. In some instances, what causes low blood pressure could be a simple case of dehydration brought on by vomiting, intense exercise, or the overuse of diuretics. Some studies have shown that a dehydration-induced weight loss of 1 percent is enough to trigger dizziness, confusion, or other symptoms of low blood pressure.
Symptoms of low blood pressure caused by conditions or diseases depend upon the specific cause of the low blood pressure. For example, if insufficient blood flows to the brain, brain cells do not receive enough oxygen and nutrients, and a person can feel lightheaded, dizzy, or even faint. If the blood pressure is already low, standing can make the low pressure worse, to the point of causing symptoms. 2  The development of lightheadedness, dizziness, or fainting upon standing caused by low blood pressure is called orthostatic hypotension.
