    I think it has something to do with needing more oxygen, just like doing push-ups will help and so will running around or even just stopping your breathing for ~30 seconds. Your body will eventually go into a higher alert state.

    It just helps for a short bit though, when you relax your nasal passage does too and blocks all again.
