Remember Urine is 95% water and theres some salts in there also, these are both very important against Asthma. You see when you have an attack its because the body is trying to steal water from the lungs in order to give to another needy area through its water regulatory system called Histamine. If the lungs gave the water up then they would shred and you would die so it fights this action giving you the symptoms of Asthma. It doesn't matter if you drink like a fish you can still get this simply because people do not balance the water with real salt (himalayan) in order for it to hydrate the body, it floods back out otherwise to protect the last minut salt reserves. So read up on Dr Batmanghelidj and follow his work. If you suffer an attack just drink 1 glass of water then put a tsp of salt on the tongue and drink another glass of water and you'll be just fine!
