Could there be a significant link between dehydration and sinus problems?

About 3 months ago I saw an alternative doctor for a completely different
reason than the sinus stuffiness that I continued to experience. During the
course of the exam, the doctor determined that I was dehydrated even though
I consistently drink about ½ to 1 gallon of water daily. He explained that
despite the quantity of my water intake that I was not retaining the water.
He further explained that there is good salt and bad salt and suggested that
I begin taking ¼ teaspoon daily of Celtic Sea Salt (Light Grey) . (Note: I
have no vested interest or connection to this product, directly or
indirectly). After several days of using this salt, I began to notice a
dramatic improvement in the sinus area . there seemed to be much less
stuffiness during the daytime and at nighttime. I thought this dramatic
improvement to be curious and, before sharing my experience, I waited to
discern if this improvement was most likely due to using Celtic Sea Salt.
The product can be bought at a health food store and cost only about $4.00.
While this additional improvement could be due to other reasons (see below),
I personally have come to believe it is due solely to the Celtic Sea Salt;
therefore, I thought that others might find this simple product worth trying
and helpful.

Instructions:
If you decide to try this Celtic Sea Salt, daily and in the morning, put a ¼
(to ½ teaspoon) in water (it is a very coarse salt) and stir it until
dissolved. I drink this mixture and follow with additional water. It's a
very light tasting salt, unlike table salt. The product I received at the
doctor's office comes in a plastic, resealable bag.

Other successful sinus methods I use:
About a year ago I began using the "upside down sinus flooding" method using
Xlear (a nasal rinse product that I had on hand at the time), and using this
method has completely eliminated a constant vibration that had been
occurring for several years in my sinuses and that an ENT doctor was
unsuccessful in treating. At first, I used this flooding method about 2x a
month for about three months and then the maintenance use has decreased over
time to about once every two months (shortly after using the flooding
method, the vibration in the sinus area was completely eliminated and has
never returned). I also use Yoga breathing exercises to help with the
feeling of stuffiness, but I am fairly certain that neither of these methods
were the reason for the additional, dramatic improvement I had when I began
using the Celtic Sea Salt.

Good luck . and feel free to write me at my e-mail address also if you have
any other questions.
