My new approach to breaking up chest congestion is an old idea.  Steam from a wet sauna, humidifier or pot of water is a traditional way to help with bronchitis.

I build a steam hookah, or stookah to generate steam.  A CPAP hose slips right on.  Boiling water generates air too hot to inhale and melts the hose.  Instead, the water is heated to a comfortably warm temperature. 

If I take a break, the lid has to be removed from the pot to keep the hose from melting.

The stookah works quite well.  It breaks up the chest congestion while I screw around online or watch TV.  A more robust hose would be good, but this works fine if I’m cautious.
