While playing the game, my hydration meter dropped down to "flashing red" which caused me to start loosing health. I had a box of cereal and a bag of salty stix, which I consumed, and as a result my health began to rise even though my hydration meter was still at "flashing red".

There was a bug in the past where drinking water at "flashing red" hunger regained health, and this is the opposite form of that same bug.
