health idea

i dont know if this will work but it came to me in a dream last night. a way to cure/relieve asthma symptoms. 1. bring a toothbrush with you 2. do strenuous activites, brush the inside of your mouth and use this to help spit out all the gross stuff. 3. take a break for a couple minutes 4. do these steps 2 more times. 5. breathe easier a few minutes later because the airway is clean. overall this will strengthen the lungs as well reducing asthma symptoms. this came to me in a dream so there is a good chance itis crazy and will not work, but maybe there's something to it.
